Island communities, which rely on marine resources, are increasingly facing risks such as global climate change and overfishing, leading to lowered catch rates and biodiversity loss. This not only threatens ecosystems, but livelihoods as well; thus, sustainable ocean and fisheries management actions are critical in maintaining habitat integrity and increasing fish populations. Developing legal policy and restoring habitats are two important sustainability actions; however, these methods do not always ensure community buy-in or acceptance. A growing field in resource management involves the use of Behavior-Centered Design (BCD) and Community-Based Social Marketing (CBSM) to improve community involvement and adoption of management measures, working with communities to encourage behaviors that promote the sustainable use of ocean resources. BCD and CBSM combine how humans make decisions with steps to design programs to improve inclusion and collaboration, and enhance impact such as to increase successful adoption and implementation of conservation policies. It has been proven to be an effective tool, accelerating community support of sustainability initiatives. This project created a guidebook centered around implementing these behavioral approaches in the context of ocean and fisheries management, created with guidance from personale at the Waitt Institute, the Blue Azores Program, and the University of California San Diego. It will support conservation managers in their initiatives and outreach with communities by providing an easy-to-understand framework and knowledge base focused on behavioral approaches. The guide includes aspects such as successes and lessons learned in BCD throughout the industry, ethics and social justice,and strategies for implementation and testing for success. It presents a case study of São Miguel Island, a community with a rich culture of sustainability throughout history, as well as in current fisheries and ecosystem conservation programs. The island is in the Azores archipelago, an autonomous region located about 1000 miles off the coast of Portugal. A supplemental ArcGIS StoryMap web page was created to highlight the rich marine-based culture of communities on São, Miguel Island. The guide will act as a resource that can support marine managers in their initiatives, improving inclusion, equity, and increasing the chances of effecting long-term change.Please see media created for this project here: https://storymaps.arcgis.com/stories/a9faa311e62640a5b830b679cb80bb88

Newspapers and archives from Taiwan indicate a long history of Taiwan's commercial fishing in the Pacific that has largely been overlooked. Using these resources, this article analyses the relationship between the Taiwan government and Taiwan fishermen in the Pacific from the 1940s to the 1980s, demonstrating how non-state actors such as fishermen dictated Taiwan's official engagements in the region. I first outline the history of legal and illegal fishing by commercial Taiwan vessels in the Pacific from the 1940s to the 1980s. I then draw on two case studies: illegal fishing incidents in Tuvalu and Australia involving commercial Taiwan fishermen, and legal fishing operations in American Samoa. These case studies demonstrate how commercial fishermen impacted Taiwan-government engagements in the Pacific and were viewed by the government as a liability. The article concludes by connecting Taiwan's commercial fishing history in the Pacific with the larger history of Taiwan in the region. [ABSTRACT FROM AUTHOR]

When investigating potential causes of apparent declines in European brown trout angling catch rates over recent decades, fisheries management procedures are rarely considered. Using a 20‐year dataset of brown trout stocking and angling catch rates, we found a significant decline in brown trout angling catch rates in streams of East Bohemia, Czechia, were well predicted by a reduction in the number of brown trout stocked at catchable size (i.e. age‐3+). Increased stocking of smaller sized brown trout, and recent sporadic efforts to stock large brown trout, had no effect on catch rates. Our findings suggest that brown trout catch rates were related to 'put‐and‐take' stocking, in which non‐native rainbow trout gradually replaced brown trout in both stocking and catches. Our study stresses the importance of considering historical fisheries management, a sometimes‐neglected factor, when studying angling catches of economically important species.

ABSTRACT Changes in population demographic structure can have tangible but unknown effects on management effectiveness. Fishery management of Pacific salmon is often informed by estimates of the number of spawners expected to produce maximum sustainable yield (SMSY), implicitly assuming that reproductive output per spawner does not change over time. However, many salmon populations have experienced long‐term trends in age, sex and length compositions that have resulted in smaller body sizes of mature fish. We present an empirically based simulation approach for evaluating management implications of declining reproductive output resulting from shifting demographics. We simulated populations with or without demographic trends, selective or unselective harvests, and harvest policies based on assessment methods that did or did not account explicitly for demographic trends when estimating SMSY. A management strategy evaluation showed reduced expected harvests and run sizes when populations exhibited negative demographic trends. Reduced abundances and increased conservation risks (higher probability of falling below an abundance threshold) could be partially mitigated by using stock‐recruitment analyses based on total egg mass instead of spawner abundance, or via precautionary management where target escapements were higher than SMSY, especially in fisheries that selectively removed large fish. Explicit accounting of demographic trends in stock‐recruit analyses resulted in up to 25% higher run sizes and up to 20% lower conservation risks compared to traditional methods when trends toward smaller, younger and male‐biased runs were present in the population. Conservation of population demographic structure may be critical for sustaining productive fish populations and their benefits to ecosystems and people. [ABSTRACT FROM AUTHOR]

Many nutrients found in saltwater fish are thought to promote amelogenesis in ameloblast cells during tooth development. The aim of the study is to determine the effect of LC50 toxicity on saltwater fish powder on zebrafish embryos. The experimental research method was a post-test-only control group design, consisting of eight groups, namely the negative control and the internal group using embryo media, the positive control using 3,4-dichloroanillin, and the treatment group 125 µg/ml, 250 µg/ml, 500 µg/ml, 1000 µg/ml, 2000 µg/ml, and 4000 µg/ml using 384 zebrafish embryos. Saltwater fish powder is diluted and observed for 96 hours, controlled every 24 hours. There were no dead zebrafish embryos from various concentrations, negative control, and internal control. The toxicity test of saltwater fish powder from the lowest concentration of 125 µg/ml to the highest concentration of 4000 µg/ml showed no signs of zebrafish embryo mortality nor developmental abnormalities. It can be concluded that saltwater fish powder is non-toxic. [ABSTRACT FROM AUTHOR]

The fishery sector is expected to overcome the food crisis. Indonesia is one of the leading countries in terms of high volumes of fishery production in most of its areas, including the Regency of Tuban in East Java Province. The area of Tuban Regency is 1,839.94 km2 with the coastline covering 65 km and a sea area of 22,608 km2. This study aims to provide information regarding aquaculture production, diversity, and distribution in Tuban. This study used a survey method to collect fishery commodity data directly from aquaculture areas. The results of this study showed that the highest production came from the brackish water with a value of 32.46% (13,561.79 tons), followed by rice field pond (27.79% or 11,612.45 tons), freshwater pond (25.76% or 10,764.62 tons), floating net cage (13.97% or 5,836.59 tons), and marine (0.1% or 5.67 tons). Aquaculture biodiversity in Tuban consisted of 11 families and 14 species of the main aquatic produces, such as Cyprinidae (Cyprinus carpio, Barbonymus gonionotus, Parastromateus niger), Clariidae (Clarias bathracus), Pangasiidae (Pangasianodon hypophthalmus), Penaeidae (Penaeus monodon, Litopenaeus vannamei), Channidae (Channa striata), Cichlidae (Oreochromis niloticus, Oreochromis mosammbicus), Osphronemidae (Osphronemus gourami), Serranidae (Epinephelus sp.), Lutjanidae (Lutjanus sp.), and Chanidae (Chanos chanos). Cyprinus carpio, or common carp, is a fish cultivated in four different aquacultures, namely rice field pond, floating net cages, freshwater ponds, and brackish aquaculture ponds. Unfortunately, the diversity and production of marine aquaculture have not been improved even though Tuban has large marine areas. [ABSTRACT FROM AUTHOR]

This research was aimed to examine the habitat characteristics, growth patterns and condition factors of T. tambra in the Mamis River, Leuser Ecosystem Area, Aceh, Indonesia. This research was conducted on the Mamis River in three different river conditions from July to August 2023. The ecological parameters of T. tambra were conducted by observing the main, broodstock, spawning, and nursery ground habitats based on diversity of catch size at a location, water quality, aquatic substrate, aquatic vegetation, and water shade. The growth pattern parameter was also analysed to reveal the condition of T. tambra. The T. tambra habitat in the Mamis River includes broodstock and spawning habitat with the criteria from small to large rocks overgrown with Bryophytes, gravel and sand substrates, clear water color, slow to swift water currents, and river environment. Most of it is primary forest. In the main habitat, there is dominant riparian vegetation in the form of forest timber trees such as Pometia pinnata, Ficus fistulosa, Hydnocarpus castanea, and Aglaia tomentosa. The habitat for the juvenile is in the form of rocks, gravel substrate, clear water color, and fast water currents. In the nursery habitat, the dominant riparian vegetation is Balakata baccata. Based on the results of the water quality analysis at the three stations show that temperature, pH, DO, currents, BOD, COD are significantly different, but brightness levels are not significantly different. The analysis of the length-weight relationship shows that the condition of the fish is stable, and sufficient food is available. [ABSTRACT FROM AUTHOR]

The pomegranate plant is considered one of the medicinal herbs rich in antioxidants that can be used in aquaculture to support immunity and health. The objective of this investigation was to ascertain the impact of pomegranate peel (Punica granatum) extract (PPE) on growth performance, the intestinal bacteria count, total number of fungi and histological analysis of the grass carp. One hundred five fingerlings (11.04±0.22g) were distributed among 21 aquariums (60-L) in a completely randomized design (triplicated) and fed diets containing 0, 0.5, and 1% PPE for 70 days at a feeding rate of 3% body weight. A spectrophotometry assessment indicated for PPE that the total phenol content was 151.09 and 175.95 GAE/100 g, and flavonoid content was 36.04 and 42.89 RE/100 g, respectively. The results of the present work revealed that growth indicators (final weight, weight gain, specific growth rate (SGR), and feed conversion ratio (FCR)) increased (P<0.05) in the PPE group in comparison to the control group. PPE had an impact on the total count of aerobic bacteria or lactic acid bacteria (LAB), but the experimental treatments dramatically decreased the amount of enteric Gram-negative bacteria (P<0.05). The total fungi count showed a significant increase in all treated fish (P<0.05). Also, histological examination showed improvement and elongation of the villi, as well as an increase in goblet cells for the treatments supplemented with PPE. Therefore, it is recommended to use PPE (0.5%) as a diet additive for grass carp to improve their growth performance and health. [ABSTRACT FROM AUTHOR]

Fishing activities negatively impact fish populations, potentially causing a decline in fish stocks. Nevertheless, ensuring diversity and connectivity among populations can mitigate these adverse effects. To evaluate the connectivity of river mouths in the western part of Southern Java waters, we sequenced forty Stiphodon semoni individuals from five populations using mitochondrial cytochrome oxidase subunit 1 as molecular markers. The study revealed that S. semoni populations showed high diversity (0.821), with the population in Cimaja displaying the lowest diversity (0.464). Furthermore, the result of the analysis of molecular variance was a Fst value of 0.0630 with a p-value of 0.22. These results, along with the result of the haplotype network, indicated no significant genetic differences among these populations. This implies that the river mouths in the western part of Southern Java waters are interconnected. The distribution of mismatches showed a single peak, indicating that the populations have undergone demographic expansion. This information could be valuable for the conservation and management of S. semoni in the western part of the Southern Java waters. [ABSTRACT FROM AUTHOR]

Microplastics can be ingested by marine organisms, including fish. Although it has been widely reported, further information regarding microplastic contamination in commercial fish is still needed. This study aimed to analyze the presence and concentration of microplastics in the digestive tract of the mackerel R. kanaguarta and red snapper L. gibbus and to identify the shape, size, color, and type of microplastic polymer. Digestion of the organic materials was performed using a 10% KOH solution, which was then filtered using a vacuum filtration system. The particles were observed using an Olympus microscope and clarified using FTIR. The results of the research showed that R. kanaguarta and L. gibbus landed at the Beba Fish Landing Base (PPI Beba) Takalar were contaminated with microplastics with a microplastic concentration in R. kanaguarta 0.21 ± 0.06 particles/g and L. gibbus 0.11 ± 0.04 particles/g. The microplastics found were fiber and fragment of varying colors, such as black, white, red, and yellow. The size of microplastics was dominant in the size class < 2 mm. The FTIR analysis confirmed the presence of polypropylene (PP), Ethylene/Propylene Copolymer, Nylon, Polyethylene terephthalate (PET), and polyester (PES). This study showed that both commercial fish species were contaminated with microplastics. These findings suggest that microplastics are widespread and contaminate commercial fish caught from Takalar waters. Further research is still needed on other seafood from this region, and analysis of polymer types such as FTIR is important to carry out as one of the standard methods in microplastic research.

The mangrove ecosystems in Bawean Island are degraded due to anthropogenic activities and land conversion. Plantation has been carried out periodically, and this has continued in several mangrove ecosystems. This study was conducted to evaluate the physicochemical water quality of several mangrove ecosystems on Bawean Island, as well as phytoplankton as bioindicators. The evaluation of mangroves in Bawean Island was carried out at 11 locations based on different naturalness and human activities surrounding. The physical and chemical parameters of water observed were air temperature, water temperature, pH, TSS, dissolved oxygen (DO), biochemical oxygen demand (BOD), salinity, conductivity, nitrate, and orthophosphate. Community structure and plankton diversity measured include the Importance Value Index (IVI), Shannon-Wiener diversity index (H'), Simpson dominance index (Id), evenness index (E), trophic diatom index (TDI), and pollution tolerant value (%PTV). The physical parameters of water chemistry show that it meets the quality standards based on Indonesian Government Regulation No. 22 of 2021, except for nitrate and orthophosphate, but it is still under plankton tolerant. A total of 63 species from 7 phytoplankton classes were found based on the importance value index. Based on the TDI index, mangrove ecosystems Sawahmulya, Sidogedungbatu, Hijau Daun, Pamona, Pasir Putih, Sungai Rujing, Bangsal, Jherat Lanjheng, and Lebak were classified as eutrophic while Pulau Cina and Dekatagung were hypereutrophic. Based on %PTV, the Hijau Daun mangrove is the best mangrove ecosystem, while other mangroves were classified as moderately and heavily polluted. [ABSTRACT FROM AUTHOR]

Exploring the length-weight relationship of fish and characterising growth parameters is essential in fisheries as they offer fundamental biology and population dynamics data to establish good management strategies for fisheries resources. This study examines the growth and mortality patterns of Oreochromis mossambicus. Data was collected between September and December 2022 using quantitative descriptive survey sampling. The study involved 20 repeats and deliberate random sampling of 30-50 fish per sample, emphasising total length, weight, and sex parameters. Based on 726 samples of O. mossambicus (352 fish identified as male and 374 fish identified as female). The growth model study revealed the typical negative allometric growth for both sexes (male and female). Male individuals attained a length of 33.449 cm after 37 days has a growth trend ± 0.3265 year-1, and females reached 21.150 cm in 34 days with a growth rate around 0.3135 year-1, as per the von Bertalanffy growth model. There were complex mortality patterns, with males contributing to most total deaths. This study emphasizes the complex biology of tilapia and its untapped potential in the aquaculture pond system ecology in Tarakan. [ABSTRACT FROM AUTHOR]

Understanding fish reproduction biology, particularly sexual maturity, the reproductive cycle, and fecundity, is useful for managing fisheries. The reproduction of Giuris margaritaceus in Limboto Lake is regrettably unknown. Over a year, fish specimens (N = 662) were gathered. They ranged in length from 6.5 to 20.9 cm (mean SD 10.9±2.5). Fecundity varied from 30,057 to 61,920. The first sexual maturity of male and female fish occurred at different sizes, 11.2 cm and 10.3 cm, respectively. This information is needed to determine this fish's lowest acceptable harvest length under the management aim to enter all-female fish for reproduction at least once. We estimated the reproductive of G. margaritaceus cycle using the size of the oocytes, histological analysis of the ovaries, and monthly mean GSI. These techniques produced the same reliable conclusion: G. margaritaceus can spawn yearly, with maximal between September and October. Based on this finding, spawners of G. margaritaceus can be kept from entering the reproductive stock between September and October. Future efforts to fine-tune fishing efforts for the effective management of G. margaritaceus may be aided by the study's findings. [ABSTRACT FROM AUTHOR]

Vietnamese balm (Elsholtzia ciliata) is a prominent herb in Vietnamese traditional medicine. This study investigated the impact of Vietnamese balm leaf essential oils on the growth of striped catfish (Pangasianodon hypophthalmus) in the juvenile stage. Essential oils were extracted using steam distillation, following European Pharmacopoeia guidelines. Gas chromatographymass spectrometry identified the essential oil components. The experiment encompassed three treatments: 0% (control), 3%, and 5% of Vietnamese balm leaf essential oils in a completely randomized design. The results demonstrated a time and dose-dependent modulation of striped catfish growth by the essential oils. Diets enriched with 5% Vietnamese balm leaf essential oils significantly enhanced survival rate and growth, indicating potential as a fish feed additive. The essential oil yield was 0.83% dry weight, with major components including (Z)-ß-Farnesene (24.02%), neral (15.06%), geranial (15.02%), and ß-ocimene (13.61%). Additionally, the study emphasized the growth-promoting effects of herbal extracts on various growth parameters. Further investigations should explore the impact of Vietnamese balm essential oil on catfish immune response and disease resistance, providing a comprehensive understanding of its potential benefits.

Lymphocystis disease has a broad host range and has been reported to enter Indonesia. However, information regarding its susceptibility and predilection organs in fish is lacking. This study examined the susceptibility of four important fish species in Indonesia, namely, giant gourami (Osphronemus goramy), hybrid tilapia (Oreochromis sp.), Siamese fighting fish (Betta splendens), and hybrid catfish (Clarias sp.). The fish were infected with virus filtrate by intraperitoneal injection and immersion. The postinfection observation period was 60 days. Viral load was quantified by qPCR and expressed as major capsid protein (MCP) copy number/mg tissue. Mortality was observed in all fish species, with the highest recorded in hybrid catfish and the lowest in Siamese fighting fish. All the fish species showed changes in their clinical symptoms, such as anorexia and separation from schools. However, only giant gourami showed internal change seven days after injection (dpi), with white lesion detected in the liver. Viral load quantification showed that LCDV had different predilection organs in the four fish species. The highest viral load of giant gourami (1.7 x 104) was observed in the liver at 7 dpi, hybrid tilapia (7.5 x 103) was observed in the fins at 21 dpi, Siamese fighting fish (8.4 x 103) was observed in the fins at 14 dpi, and hybrid catfish (1.2 x 103) were observed in the fins and gills at 7 and 14 dpi. The findings indicated that giant gourami, hybrid tilapia, Siamese fighting fish, and hybrid catfish were susceptible to LCDV infection with different predilection organs. [ABSTRACT FROM AUTHOR]

In many marine ecosystems, the fish population has been correlated to bycatch related activities, the most frequently fisheries activities in Malaysia, while the relative importance of other factors such as the depth of artisanal fish trap remains understudied. We investigate whether the bycatch distribution would be affected by deployment of artisanal fish trap at different depths, placed at extensively studied marine educational university station, the Bidong Island, East Coast of Peninsular Malaysia, Terengganu. The traditional artisanal fish trap with a dimension of 1.52 m x 0.92 m x 0.92 m with the wooden frame and the oval shape funnel with a diameter of 25 cm x 6 cm and 25 cm of entrance depth were used for sample collection. The results show that there are six families, six genera and seven species of fish were successfully captured with a 20 m depth captured more fish species compared to others (i.e., 10 m and 15 m depth). The findings of this study provide evidence of the relationship of fish trap depths and fish distribution in the wild. This information could be useful for fishermen for further deployment of their fish trap within the sampling areas in the future. [ABSTRACT FROM AUTHOR]

The focus of this study on understanding the structure and dynamics of rhizosphere bacteria in mangrove ecosystems is driven by the increasing acknowledgment of the crucial roles these microorganisms play in ecosystem functioning. Rhizophora mucronata, a key mangrove species, is known for its ecological significance. Investigating the bacteria associated with its rhizosphere offers valuable information about the symbiotic relationships between mangrove vegetation and microbial communities. Bacteria are vital for decomposition and nutrient availability in mangroves. This research examines sediment from rehabilitated and natural areas to understand how human and natural factors shape bacterial communities. The DNA sequence was analyzed using Next-Generation Sequencing (NGS), which targeted the 16S bacterial region in the V3-V4 rDNA. Additionally, environmental factors such as nitrate, phosphate, and sulfur content were also analyzed. Kruskal-Wallis and T-test statistical analyses were used to examine the abundance of bacteria and environmental parameters between study sites. There are differences in the types of bacteria found in Kuala Langsa and Telaga Tujuh. Approximately 7% of the rhizosphere bacterial groups were exclusively detected in Telaga Tujuh, such as Fusobacteriia (Class). Additionally, the abundance of bacteria at both locations differs significantly (p < 0.05), as determined by Kruskal-Wallis. The results of the t-test indicate that the observed environmental parameters do not differ significantly from each other. The environmental parameters studied did not significantly impact the types or abundance of detected rhizosphere bacteria. [ABSTRACT FROM AUTHOR]

Chlorophyll-a has been considered an indicator of pelagic fish abundance in waters. Although a high nutrient load causes eutrophication, leading to fish mortality, global-scale climate anomalies will also influence the oceanographic conditions of the seas. This study aimed to investigate spatial patterns and trends of chlorophyll-a, the relationship between chlorophyll-a and pelagic fish catch productivity, and the effect of ENSO and IOD on pelagic fish catch productivity. The chlorophyll-a data were obtained from the SeaWiFS and Terra-Aqua MODIS time-series datasets of ocean color satellites. The results indicated that Jakarta Bay had the highest chlorophyll-A concentration. The Chlorophyll-A concentrations declined as the distance between the estuary and the coast grew. From 1997 to 2021, the regional pattern of increasing chlorophyll-a concentrations in the Citarum and Cisdane estuaries was continuous. Since 2001, the concentration of chlorophyll-a in Jakarta Bay has declined, whereas it has begun to climb in the seas of the North Seribu Islands. The increasing chlorophyll-A trend in the Seribu Islands is attributed to rising nitrate levels induced by human-driven coral degradation. Between 1997 and 2021, the concentration of chlorophyll-a in the Muara Bendera fishing region grew by +0.013 mg/m3/year, or 1.43 percent each year. The correlation between chlorophyll-a and pelagic fish catch productivity was -0.13. ENSO does not affect the productivity of pelagic catches in this region. However, it was discovered that IOD reduced the productivity of low-category pelagic catches. [ABSTRACT FROM AUTHOR]

Genus Nomorhamphus is an endemic fish that can be found in Sulawesi, Indonesia. This fish belongs to the halfbeak group and has diverse colors and morphology. It has economic value as an export commodity in the ornamental fish trade. Exploration of the genetic relationship of genus Nomorhamphus in Central Sulawesi is still limited. Nomorhamphus's fulfillment of export demand still comes from wild catches. This study aimed to identify the genetic relationship of genus Nomorhamphus in the inlet rivers of Lake Lindu, Central Sulawesi, and evaluate the adaptation response of genus Nomorhamphus to different wavelengths of light exposure. Caudal fin of six fish from the three inlet rivers of Lake Lindu were preserved in 95% ethanol for DNA extraction purposes. This research used a completely randomized design with three treatment, namely rearing under white (400 nm), green (525 nm), and red (625 nm) light for 60 days. Each treatment had three replications in the form of aquariums, with each aquarium being filled with four fish. A total of 42 fish were utilized in the study. CO1 sequence was amplified with universal primers of FISH-F2 and FISH-R2. The PCR amplification products were then sequenced and performed with phylogenetic tree analysis. The genetic diversity analysis suggests that the genus Nomorhamphus of all three rivers, Lindu Lake, Central Sulawesi is one species as Nomorhamphus sp. Male and female growth length and gonad maturation were developed faster under green light exposure, while survival rate, blood glucose level, and color quality were not significantly different under different light. Exposure of wild fish to green light Nomorhamphus sp. can accelerate gonad maturation and growth to accelerate domestication. [ABSTRACT FROM AUTHOR]

Aeromonas hydrophila, a gram-negative bacterium, is a major pathogen responsible for various diseases in mammals, reptiles, amphibians, fish, and humans. Targeting the specific toxin aerolysin in A. hydrophila is crucial to address antibiotic resistance and the lack of adequate and protective vaccines against this intracellular and extracellular pathogen. This study aimed to identify a multi-epitope vaccine (MEV) candidate targeting the aerolysin toxin to combat the disease effectively. Standard biochemical characterization methods, detection of PCR, and sequencing of the 16S rRNA, rpoB, and aerA genes identified the isolate AHSA1 as A. hydrophila isolated from O. goramy. Subsequently, we identified B and T cell epitopes on the aerolysin protein and predicted MHC-I and MHC-II epitopes. The epitopes were then evaluated for toxicity, antigenicity, allergenicity, and solubility. The vaccine design integrated multi-epitope constructs, utilizing specialized linkers (GPGPG and EAAAK) to connect epitope peptides with the cholera toxin B subunit as an adjuvant, thereby enhancing immunogenicity. Ramachandran plots showed that 85.25% of the residues were in the most favorable regions, followed by additionally allowed regions (10.80%), generously allowed regions (1.30%), and disallowed regions (2.65%), confirming the feasibility of the modeled vaccine design. Based on docking simulations, the MEV had strong binding energies with TLR-4 (-1081.4 kcal/mol), TLR-9 (-723.2 kcal/mol), MHC-I (-866.2 kcal/mol), and MHC-II (-9043.3 kcal/mol). Based on computational modeling, we expect the aerolysin MEV candidate to activate diverse immune mechanisms, stimulate robust responses against A. hydrophila, and maintain safety. The significant solubility, absence of toxicity and allergic response contribute to the potential clinical utility of this vaccine candidate. [ABSTRACT FROM AUTHOR]

Squids play vital ecological and economic functions as keystone species in marine food webs and integral components of global capture fisheries. However, a comprehensive understanding of their diversity and life history characteristics in Indonesian waters is still poorly understood. This study aimed to identify squids that inhabited Java's northern and southern coasts and examine their growth pattern through morphometric analysis. Six hundred eighteen squid samples were collected fishers caught from May to September 2022 in Blanakan and Palabuhanratu Bay, representing two areas of interest. The body size and the shape of sucker rings of squids were observed using morphometric method. Kruskall-Wallis test, Principal Component Analysis, and Spearman's correlation were performed to investigate morphometric variation and relationships. The length-weight relationships were estimated for each species. This study reported three species of squid on the north and south coasts of Java, namely the mitre squid (Uroteuthis chinensis), the Indian squid (Uroteuthis duvaucelii), and the purpleback flying squid (Sthenoteuthis oualaniensis). There were significant differences observed in ten morphometric variables among the three species of squid (p < 0.05), with fin width, fin length, and sucker ring teeth identified as the key distinguishing feature for the squids. Spearman's correlation indicated stronger associations between mantle and fin variables (ρ = 0.666-0.967, p < 0.05) than those between mantle and head variables (ρ = 0.380-0.864, p < 0.05). Mantle length-weight relationships revealed a hypoallometric growth pattern for U. chinensis and U. duvaucelii, while S. oualaniensis exhibited an isometric growth pattern. The finding of this study provides valuable insights concerning the growth of squids that reflect variation in ontogenic development, trophic ecology, and environmental conditions in Indonesian waters.

While climate change may amplify global mobility patterns, most affected individuals voluntarily stay in their locales. This research studies the multiple forms of voluntary non-migration amidst socio-environmental challenges, focusing on the traditional fishermen community in southwestern Bangladesh. Through 25 in-depth interviews and two focus group discussions, the research uncovers that despite socio-environmental obstacles, such as the loss of the primary source of livelihood – the river, a substantial number of fishermen are determined to stay in the locality voluntarily. The households who voluntarily stay face livelihood challenges that coexist with their vulnerabilities. The fishermen employ diverse livelihood strategies to cope with the adversities and strive to maintain their livelihoods in situ. This study emphasises that voluntary non-migration could serve as both an adaptation strategy in vulnerable locales and an outcome of livelihood decisions, highlighting its fluid and dynamic nature. The implications of these findings are relevant for future research and policy formulation in promoting local adaptation and supporting the population choosing to remain in place in the face of environmental challenges.

Using a lab-in-the-field experiment with Ugandan fishers, we study if and how the use of a common pool resource changes when the resource is either scarce or abundant and when the number of users increases over time. Both resource scarcity and a growing group require users to be more constrained, that is, more cooperative, in order to maintain the resource. However, the results show that fishers do not curtail their harvesting behavior under increased pressure, leading to rapid overexploitation when scarce resources are used by a growing group. This implies a particular need for sustainable management when scarce resources are exposed to in-migration. [ABSTRACT FROM AUTHOR]

The Ennore wetlands in North Chennai, India were once dense with diverse habitats and interwoven histories. Many of these histories began to unravel from the 1960s onwards, when state‐sponsored heavy industry began encroaching into and polluting the wetlands. Local fishers, whose lives, livelihoods, and cultural worlds were ignored by these changes, fought back in a campaign to reclaim and restore the wetlands. This paper analyses how the Save Ennore Creek Campaign and Ennore fishers used counter‐mapping strategies to reveal the state's wilful suppression of fisher knowledge and worldviews using maps and plans. It draws from decolonial and ignorance studies literatures to analyse the campaign's counter‐maps as cartographic, performative, and affective insurrections of subjugated knowledges and counter‐histories that un‐made the state's maps and plans, exposed the state's knowledge as wilful ignorance and spotlighted geographical knowledge from the margins as a way of remaking reality and opening up possibilities of alternative futures for the creek and its communities.

ABSTRACT Sustainable management of recreational fisheries requires balancing angler attitudes and behaviour with fisheries' biological potential. Herein, we investigated the balance in the sea‐run brown trout (Salmo trutta) fishery around the Swedish island of Gotland using data collected through a creel survey, test fishing, and spawning returns to selected streams. Anglers accurately anticipated catches of large fish but underestimated the role of natural reproduction in supporting the stock. Female sea trout entering spawning streams and post‐spawn sea trout caught on the coast were significantly larger than spawning males and non‐spawned fish, and were particularly important for the fishery. Larger sea trout also faced a higher level of harvest pressure than other sizes. Small changes to angler preferences, harvest rates, or regulations could significantly influence characteristics and sustainability of this fishery. The scale and direction of these changes merit further investigation. [ABSTRACT FROM AUTHOR]

ABSTRACT Artisanal fishing significantly not only contributes to socioeconomic development of numerous countries but also exerts pressure on natural populations. The white shrimp (Penaeus schmitti) is a key species in Brazilian artisanal fisheries, yet it is currently classified as data‐deficient. Conducting comprehensive studies on its population dynamics is essential to establish reference points that guarantee sustainable fishing. Therefore, we estimated population parameters to assess status of the white shrimp stock captured by beach seining in Northeast Brazil. Monthly samples of white shrimp were collected using a beach trawl. Based on population parameters, the white shrimp population in the study area, the sex ratio was 1 male to 1.29 females, with females larger and heavier than males. Weight–length relationships revealed positive allometric growth for males, females, and grouped sexes, with no significant difference between sexes. Asymptotic length, t_achor, and growth performance index also did not differ between sexes; however, the growth coefficient was higher for females. Beach trawling in northeastern Brazil predominantly targeted adult white shrimp, with carapace length at first capture (Lc50) averaging 2.12 cm for females and 2.19 cm for males. Mortality and exploitation rates were below maximum sustainable levels, so the stock was classified as underexploited. Overall, beach‐seine fishing was less harmful to this stock (F = 1.42) than motorized fishing and can be considered a sustainable fishing activity for the white shrimp population.

In the transition period of the Yangtze River fishing ban policy, the retrenched fishermen are in an inferior position in the employment market due to the lack of their own employment capital, and it has become a problem to switch to employment. Based on the study of employment quality and employment capital theory, this paper uses the PLS-SEM model to process the questionnaire data on the effect of government employment services on the quality of fishermen's re-employment based on the establishment of government employment services-quality analysis system and questionnaire design and collection. The total effect of government employment services on re-employment quality was 0.685. The indirect effect of government employment services on the quality of re-employment through the mediating variable of employment conditions was smaller than the direct effect of government employment services on the quality of employment. This research may provide a basis for solving the problems of high-quality re-employment for unemployed fishermen and sustainable livelihoods for fishermen. [ABSTRACT FROM AUTHOR]

Managing economic risk is a challenging endeavor for fishers. One of the ways to mitigate such risk is through income diversification spanning even beyond fishing activities. However, the role of non-fishing income on risk management has been poorly understood. Here we investigate the relationship between fishing risk levels and secondary incomes by analyzing risk levels of fishers' incomes from fishing, non-fishing, and partner income sources for Swedish fisheries from 2004 to 2015. We find that fishers with a balanced share of fishing and secondary incomes have lower risk levels than fishers who primarily rely on fishing income. Both non-fishing income and partner income reduce risk levels. [ABSTRACT FROM AUTHOR]

Going beach-combing after tide has been a major means of life and work for fishermen by the sea for thousands of years. These fishermen picked up and accumulated wisdom in their work, thus shaping a unique culture of beach-combing. Based on the analysis of the characteristics of seafood-collecting video clips produced by the current self-media platforms, the essay first studies the elements affecting beach-combing from the perspectives of YanCheng's geographical locations, beach characteristics, and Marine resources and then digs into new potential forms of beach-combing suitable for YanCheng so as to evolve a distinctive local beach-combing culture. The essay also attempts to expand the popularity and reach of Yancheng City and boost its economy and culture by integrating its beach-combing culture into other local cultures, such as its sea-salt culture, wetland culture, culture of celebrities and History, food culture, and popularizing and promoting its beach-combing culture through various kinds of channels.

Tourism development is an oft-touted strategy to enhance the livelihoods of local residents and reduce their dependence on resources. This study explores the determinants of lagoon fishermen's participation in tourism-related activities and evaluates whether tourism is an alternative livelihood option for Thừa Thiên Huế Province, Vietnam. We employed propensity score matching to analyze the survey data from 265 households in the coastal area of the lagoon. Our study indicates that tourism cannot provide a sustainable livelihood for local residents if the locals forego their traditional livelihood practices and completely transform the region into a tourist attraction, even though it can contribute to increasing household income. Other factors, such as low levels of education and larger travel distances between the lagoons and existing tourist areas, are the primary barriers to fishermen participation in tourism. Finally, we analyzed the related policy and managerial implications to improve tourism and diversify the locals' livelihoods. [ABSTRACT FROM AUTHOR]

This study aims to assess the level of acceptability of the credit services of Land Bank of the Philippines (LBP) among the small farmers in Alabel, Sarangani Province who have availed credit services from the said institution. Moreover, the study determined if there is a relationship between the profile of the respondents and the factors of acceptability of credit. This study used quantitative research design particularly the descriptive-correlation research method. Descriptive statistical treatment such as frequency and percentage were applied to analyzed and interpret the gathered data. A survey was conducted and revealed that the small farmers and fishers have high regard to LBP and the credit services of the latter are more than adequate and generally exceeds the criteria relative to acceptability. Furthermore, there is a weak positive relationship between the profile of the small farmers and the acceptability factors. Hence, it signifies that the profile of the small farmers does not influence much on their views about the credit services of Land Bank of the Philippines. [ABSTRACT FROM AUTHOR]

On the Mekong, where hydropower and hybrid species have altered the river’s ecology, new sources of potential arise. As the yearly rise and fall of the river is punctuated by sporadic floods and ebbs depending on hydropower generation needs, fish and other species find their spawning and feeding cycles dramatically altered. In turn, they are replaced with new, hybrid species. In the social and religious realms, this material change gives rise to new spirits, and new networks of human and nonhuman forces. While many from the region turn to cash crops or migrant labor, others seek to make new connections by fishing this changed landscape. Through making kin with the new, monstrous river and its new denizens, through tying a new social net as old fishing nets fail, fishermen on the river reach toward new ways of belonging in altered social, ecological, and ontological worlds.

It is crucial to comprehend the factors influencing fishermen's support for a newly established Marine Protected Area (MPA) in Malacca. This understanding aids in calculating stakeholder perspectives and informs decision-making processes related to marine management. The research objectives were to identify fishermen's perception towards the newly proposed MPA in Malacca and determine the factors affecting their intention to support it. A total of one hundred fifty respondents were enlisted through a questionnaire that specifically targeted the fishermen in the Jasin area of Malacca, who were primarily affected by the gazettement of the MPA. The selection of respondents from nine fishermen bases was via stratified random sampling technique. The theory of planned behaviour (TPB) formed the foundation for comprehending the fishermen's intention to provide support. The factors were specifically mentioned. The outcome proved advantageous for the Department of Marine Parks Malaysia in comprehending the fishermen's perception and, consequently, making suitable decisions regarding the well-being of the impacted fishermen.

Background: Fishers are at risk of back disorders due to their physically demanding work. The aim was to investigate risk factors for back disorders in fishers in Denmark. Methods: All male Danish registered fishers between 1994 and 2017 were included. ICD-10 codes classified back disorders (M40-M54* and DM99.1-4*). A multistate model on a cause-specific cox regression modelwas conducted. Results: Of 13,165 fishers included, 16% had a hospital contactwith an incident back disorder, and 52% at least had 1 recurrent episode. Having worked in another occupation (HR 1.14; 95% CI: 1.02, 1.27) and another musculoskeletal disorder (HR 1.84; 95% CI: 1.69, 2.01) were significant risk factors for the incident back disorder. No risk factors were seen for recurrent episodes. Conclusions: Risk factors for incident and recurrent back disorders were different; thus, episode-specific initiatives are needed to reduce back disorders among fishers. [ABSTRACT FROM AUTHOR]

A value chain analysis (VCA) is a cost‐effective tool to guide targeted value chain development interventions to address social wellbeing and environmental performance. Examining value chains through a gender lens can help design and implement interventions that enhance opportunities for women in the fisheries and address gender inequalities in the sector. We conducted a VCA in 2015 of the wild‐caught mud crab (Scylla serrata) fishery in Bua Province, Fiji. We found five main players involved in the selling of mud crabs – fishers, traders, retail shops, restaurants and exporters. The value chain was dominated by Indigenous (iTaukei) women fishers (88.1% of fishers) and characterised by low technological input, targeted largely for domestic markets or consumption, and with limited value‐adding activities. Although most women harvested mud crabs on a part‐time basis, it was an important source of income for most with 30% relying on it as their main livelihood. Despite being a lucrative commodity, there are several bottlenecks in the fishery – the relative informality of relationships amongst players in the value chain, the independent livelihood‐driven harvest behaviours of fishers, and opportunistic sale of products. As a result, the fishery did not meet the demands of the domestic market. Our study concluded the gendered‐skewness in the fishery increases the vulnerability of the chain to declines in economic productivity because of its reliance on irregular suppliers, and gender‐based constraints. However, the low frequency and intensity of harvesting and use of low technological harvesting methods meant the fishery was not over‐exploited and likely sustainable. [ABSTRACT FROM AUTHOR]

Why do people fish for recreation? Social science literature suggests that both catch (e.g., number or sizes of fish) and non‐catch dimensions (e.g., nature experience, temporary escape) play a role. After reviewing the literature from environmental psychology, neuroscience, anthropology, recreational fisher motivation research as well as popular fishing books, I find that the opposite of catching fish, more specifically the uncertainty of the catch, maybe another, perhaps fundamental force that explains the attraction of the activity to millions of people. There appears to be strong utility in the gaming nature of the activity. This quality may contribute to explain various patterns that are well known, e.g., the overinvestment of time and money by recreational fishers that drastically exceed the market value of fish, the lack of self‐regulation of a local recreational fishery in terms of effort being spent also on low stock sizes, the disutility associated with providing certain catch probability information, diminishing marginal utility return for increasing catch rates, management regulations that make fishing harder than necessary, suboptimal satisfaction despite rising catch rates, and finally the dominance of men among populations of recreational fishers. I present a serious of testable propositions and call for a novel research focus that seeks to better understand what makes catch ambiguity attractive psychologically and emotionally.

Recreational fishing is practiced by thousands of people in European coastal waters and is steadily gaining popularity. Serving multiple purposes, recreational fishing provides fresh fish for meals, offers leisure, and contributes to traditional ecological knowledge, especially at the local level. Therefore, analyzing its dynamics and catch is a complex task, since they not only depend on the environmental features but also on the behavior of fishers. In coastal areas, however, most recreational fishers remain unmonitored, making it difficult to obtain data on their impact on fish stocks. This is particularly evident in the Venice lagoon, where we conducted a comprehensive study aiming to characterize recreational fishing dynamics. We collected data through interviews, online questionnaires, and remote sensing techniques, including satellite imagery photointerpretation and machine learning algorithms. Our findings reveal spatial and temporal variations in fishing activity, with certain areas and times experiencing higher fishing pressure. This highlights a seasonality in fishing activity and a pattern in fishers' behaviors that are associated with fish migratory dynamics. Such an association demonstrates the local fishers' understanding of the fish lifecycle phases and the environmental conditions of the lagoon. Regarding the catch, the most targeted species are seabream (Sparus aurata), seabass (Dicentrarchus labrax), and cuttlefish (Sepia officinalis), with estimated total catches of 18.65 t per year, 15.82 t per year, and 8.36 t per year, respectively. However, our results showed a significant disproportion between the biomass caught by two different groups of fishers that differ in terms of fishing trip frequency, success rate, and catch. While the average catch of the first group, representing most recreational fishers, might be considered of low impact, the catch of the second group, encompassing recreational fishers who fish with very high frequency and efficiency, is substantial in the context of the lagoon ecosystem. Indeed, even considering a conservative estimate, recreational fishing in the Venice lagoon accounted for approximately 2% of the catch of cuttlefish and 17% of the catch of seabream compared to commercial fishing catch, whereas the catch of seabass by recreational fishing approached that of commercial fishing. Therefore, the implementation of a periodic monitoring program utilizing methods such as machine learning algorithms and remote sensing technologies could support the management of recreational fishing dynamics. We also suggest that participatory processes involving both professional and recreational fishers may aid in defining shared approaches and bottom–up initiatives, ensuring enjoyment as well as sustainable uses of coastal areas.

This paper is based on ethnographic fieldwork and collected oral histories in 2019 in the Lofoten islands, as well as on archival research. I investigate the complex creation of kinship networks between humans and skrei in the Lofoten islands. I argue that the constant struggle to survive for both fish and fishermen embedded in larger capitalist ecologies of exploitation creates a symbolic shared substance between fish and fishermen, which, despite the often-unequal antagonistic nature of their relationships, allows us to rethink of definitions of kinship between humans and nonhuman others.

The Bureau of Fisheries and Aquatic Resources (BFAR) rolled-out the Dangit Processing Livelihood FishCORALProject for the fishers’ organization in Prieto Diaz, Sorsogon in mid 2019 funded by UN-IFAD. Designed to help reduce poverty through increased household income, women participation and project sustainability. This study looked into the relevance, effectiveness and efficiency of implementation and readiness in attaining project objectives. The study is mixed descriptive method and used semi-structured questionnaire, key informants interview, FGD and secondary data analysis. The project was found relevant but poor in coordination and involvement of other stakeholders. Effective but failed to contribute to poverty reduction due to late implementation, no comprehensive project plans and technical support. Inefficient as it failed to translate resources it to incomes and sustained operations. The community organizationsare not ready and capable (lack technical and business management skills). The local resources (danggit, people and community organization) guarantee sustainability if managed appropriately. Women empowerment is hardly achieved. Recommendations;1) Develop project sustainability plan (technical and business facets of theproject), capacitate the organization along leadership and business management. 2) Bioecological data be produced on danggit stock to fine tune harvesting and regenerative capacity to ensure sustainability of supply. 3) Technical support provision coming from BFAR, LGU, academe, DTI, DOST, NLRC, NGOs in the form of product development, value adding, branding & packaging, business management, access to funds, assigning a full-time community facilitator as priority. Responsibilities and commitments of BFAR, LGU and the beneficiary be concretized through a memorandum of cooperation. [ABSTRACT FROM AUTHOR]

In the early twentieth century, when little was known about the underwater realm, the question of subaquatic vision garnered much interest. Based on human laws of optics in water, observers of the time claimed to show how fish see, and the impact of illusions on fish vision. Addressing fly-fishers in particular, they raised the question of whether fish see "freak pictures" and "monsters." The present study examines five scientific visualizations published in Scientific American in 1913 to determine whether optical illusions remain relevant for fish scientists today and whether conceptions of visual intelligence in fish have changed since 1913.

Purpose: This paper aims to determine the implications of Covid-19 on the livelihood of marine fishermen. It gives a concrete picture of how vulnerable communities like marine fishermen are affected due to the lockdown policies. The paper examines these communities' present status and the extent of vulnerability during the post-Covid period. Design/methodology/approach: The study uses an exploratory research design to find the solution to the research problem. 298 samples were collected and analysed within a sustainable livelihood theoretical framework. The scope of the study is limited to marine fishermen in Kerala, residing in six districts out of the nine coastal districts. The impact of the lockdown on income was analysed using paired t-test and results linked with the theory. Findings: The study has done an empirical analysis for three periods: before lockdown, lockdown and after lockdown, to identify the impact of lockdown on marine fishermen. The study's significant findings are that these fishermen's livelihood is at risk during the post-lockdown period, and many families are moving into a "debt-trap". Research limitations/implications: Policymakers can develop appropriate policy strategies to enhance the livelihood assets of vulnerable communities to include them in a sustainable framework. Originality/value: Only a few studies are highlighting the impact of Covid-19 on vulnerable communities in India. The effects of climate change on the marine ecosystem are already endangering marine fisher folks' livelihoods. In this light, it is vital to study the extent of the impact of income shock on the livelihood assets of marine fishermen due to the lockdown policy implemented in the State to prevent the spread of Covid-19.

This study examined the growth patterns of the spotted catfish, Arius maculatus (Thunberg, 1792) in the Thanlwin River Estuary throughout the analysis of standard lengths obtained from observed otolith data and back‐calculated data. Between April 2023 and January 2024, 516 fish ranging in standard lengths from 8.3 to 33 cm were collected. The annual deposition of annuli in otoliths was confirmed using the marginal increment ratio, with ages ranging from 2 to 9 years. The Dahl‐Lea back‐calculation method expanded the length at age data to 2472 records for ages 1–9 years. Growth was characterized using Von Bertalanffy growth curves, revealing the significant differences between the observed data (asymptotic length L∞ = 25.34 cm, growth coefficient K = 0.257 year−1 and growth performance index ϕ′ = 2.02) and the back‐calculated data (L∞ = 36.23 cm, K = 0.087 year−1 and ϕ′ = 2.21). The findings of the study suggested that the back‐calculated otolith data were more dependable for determining growth parameters compared to the observed otolith data. A. maculatus appears to exhibit slow growth characteristics, suggesting that the environmental conditions in the Thanlwin River Estuary may be deficient for this species. The insights gleaned from this research are crucial for guiding and shaping fishery management policies through informed advice and recommendations. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to determine the reproductive cycle and spawning frequency of the sea cucumber Holothuria tubulosa in the northeastern Aegean Sea. Methods: The study covered a period of 12 months, beginning in October 2018 and concluding in September 2019. During this period, sea cucumber samples were collected monthly. Macroscopic and histological examinations of gonadal tubules were conducted to provide credible information for fishery management and aquaculture. Result: The sex ratio of the sampled population was 1:1.3, with 95 males and 130 females. The drained body weights at 50% maturity were 70.90 g for females and 70.80 g for males. The total length at 50% maturity was estimated at 18.58 cm for females and 18.05 cm for males. Gonad maturation was initiated in March and progressed to spawning stages between July and August. From September to February, the gonads were in postspawning and recovery stages. A strong linear correlation was determined between the gonad index and the seawater temperature in the area. Conclusion: The information provided is expected to improve stock management, enforce fishery regulations, and support controlled breeding programs. These measures aim to preserve the natural populations of Holothuria tubulosa and guarantee the long‐term viability of the species in the wild. Impact statementThe Holothuria tubulosa is the most abundant commercial sea cucumber species found in the Mediterranean Sea, particularly in the Aegean Sea. This species plays an important ecological role in nutrient regeneration and surface sediment mineralization in the benthic zone; however, there is significant catch pressure on natural stocks. This study revealed the reproductive cycle of this Mediterranean Sea cucumber species, offering crucial data for sustainable fisheries and aquaculture. By understanding their breeding patterns, we can better manage wild populations and develop controlled breeding programs, ensuring the long‐term survival of the species and supporting healthy marine ecosystems.

The implementation of the European Fisheries Local Action Group (FLAG) system applies a neo‐endogenous approach, which can restructure public intervention in favour of a mosaic of local territories. By resting on a Finnish case study, this article studies the local adaptation of the FLAG system and how FLAG managers are positioned as intermediaries in horizontal and vertical networks that enhance local fisheries' livelihoods. The analysis of the FLAG system's approaches and various roles of the managers is based on qualitative interviews and a stakeholder survey, set in the interactive governance framework. Our findings show how via its intermediary role, expertise, commitment and networking, the FLAG system, and especially FLAG managers, can mend the failures of the governance system. We conclude that the recruitment of the right type of FLAG managers can be a path towards the enhancement of local small‐scale fishers in a well‐functioning governance system. [ABSTRACT FROM AUTHOR]

The study was conducted to estimate the post-harvest loss (PHL) of inland capture fisheries in Bangladesh based on the fishing venture i.e., sole proprietorship, partnership and cooperatives using Questionnaire Loss Assessment Method (QLAM). A total of 1339 fishermen were selected using stratified random sampling where 792, 485, and 62 were involved in the sole proprietorship, partnership, and cooperatives types of fishing venture respectively. The data were collected from thirty-nine districts across six divisions through the direct interview method covering 92 fish species. The results indicated that Ashar (June-July) to Agrahayon (November-December) was the peak fishing period for every fishing venture. The study revealed that the high volumes of fishes were caught from haor for partnership and cooperatives while river was for sole proprietorship. The study accounted lower PHL for cooperatives than that of sole proprietorship and partnership and found significance differences among them from Tukey's pairwise test. The estimated PHL was higher for Puti (Puntius chola) in sole proprietorship and partnership whereas Tengra (Gagata cenia) in cooperatives venture. The study suggests to expand the cooperatives fishing ventures widely in Bangladesh where the predominant factors (i.e., longer harvesting duration, delaying in marketing the fishes and temperature, excess supply, and etc.) of causing PHL in this venture should be taken under consideration.
