Background: Phuket Province is a major tourist destination with a migrant workforce accounting for 10% of its population. Despite governmental efforts to adjust health insurance policies, migrants face healthcare access challenges. This study examines the current healthcare access situation and factors associated with unmet needs among migrants in Phuket Province. Methods: We used a cross-sectional mixed-methods approach, recruiting participants through snowball sampling from the Migrant Health Volunteer Network. Quantitative data were gathered using self-administered questionnaires, with unmet need defined as desired outpatient or recommended inpatient services not received at government hospitals. Multivariable logistic regression identified unmet need predictors, and we assessed the mediating effect of health insurance status. Qualitative data from three focus groups on healthcare access provided context and enriched the quantitative findings. Results: This study includes 296 migrants mainly from Myanmar. The overall unmet need prevalence was 14.86%, mainly attributed to having undocumented status (34.09%), affordability issues (20.45%), and language barriers (18.18%). Working in the fishery industry significantly increased unmet needs risk (aOR 2.68, 95% CI 1.08–6.62). Undocumented status contributed a marginal total effect of 4.86 (95% CI 1.62–14.54), with a natural indirect effect through uninsured status of only 1.16 (95% CI 0.88–1.52). Focus group participants used various medical resources, with insured individuals preferring hospital care, but faced obstacles due to undocumented status and language barriers. Conclusion: Valid legal documents, including work permits and visas, are crucial for healthcare access. Attention to fishery industry practices is needed. We recommend stakeholder discussions to streamline the process of obtaining and maintaining these documents for migrant workers. These improvements could enhance health insurance acquisition and ultimately improve healthcare affordability for this population. These insights could be applied to migrant workers in other urban and suburban area of Thailand regarding access to government healthcare facilities. [ABSTRACT FROM AUTHOR]

Marine elapid snakes are a diverse, predominantly Indo‐West Pacific species group. The persistent removal of some species has an unquantified but potentially dire impact on populations. We conducted the first comprehensive review of the trade in marine elapid snakes based on published literature (1974–2022) and trade data from the only species (i.e., Hydrophis [Lapemis] curtus) whose trade is monitored internationally. Some species and populations were subjected to targeted harvest for their meat and skins for at least the last century; fisheries are possibly the most significant threat to populations of marine elapids, with the highest numbers being exploited either accidentally, incidentally, or opportunistically in Southeast Asian fisheries targeting other seafood, including demersal trawl and squid fisheries. Southeast Asia is the core region for exploitation of marine elapids. Annual offtake is >225,000 individuals of at least 8 species in the Gulf of Thailand. Of 72 recognized marine elapids (all non‐CITES [Convention on International Trade in Endangered Species of Wild Fauna and Flora] species), Hydrophis curtus and Hydrophis cyanocinctus dominate the skin trade. Skins of H. curtus are traded mainly in East and Southeast Asia and, to some extent, Europe. Despite some baseline information on the trade of these species, the sustainability of their harvests, particularly in the context of the burgeoning and unmanaged nature of fisheries in the region, remains the major challenge. In an era of declining fish stocks, there has been an increasing trend to commercialize the harvest and use marine elapids that were once considered accidental bycatch and discarded. This trend will continue to pose a significant risk to these snakes unless appropriate fisheries and trade regulations are enforced. Applying the precautionary principle to prevent the overexploitation of sea snakes is an indispensable measure in which trade in regional populations should be regulated through CITES. Accordingly, management plans to identify core distribution regions of exploited species would be crucial for assigning national responsibilities to sustain species and populations in the long term.

Choice of trade route and destination by cross border traders is an important decision in today's increasingly cross border trade of products including fish. The current study examined the geographical factors influencing choice of informal trade route and destination by fish traders. Both qualitative and quantitative approaches were adopted for the study. These included semi-structured questionnaires through personal interviews and key informant interviews with fish border inspectors. Data was analyzed through various techniques for trader's choice and destination. Specifically, principal component analysis and spearman correlation, and Huff's gravity model were used to identify significant factors influencing choice of trade route and destination, and market attractiveness, respectively. Fish traders bypass official border posts using informal routes connecting the main route before and after the border post. Despite attempts and awareness about formal trade, stringent regulations forced fish traders to use informal trade routes. However, investigations into choice of trade routes and destination found that route distance, presence of alternative destination, mode of transport, demand of the fish product, and personal safety and risks were the factors influencing choice of both trade route and destination by informal fish traders. This geographic analysis provides a basis for addressing challenges in informal cross border trade in Malawi. It is recommended that strategic efforts and investments should be made in the development of transportation infrastructure, such as roads and railways to improve connectivity between secondary routes and one stop border post. The government should also intensify awareness initiatives on COMESA simplified trade regime (STR) to encourage informal traders to transition to the formal sector through use of formal routes.

Telling stories can be an empowering exercise, providing important insights into the values and priorities of the storytellers. This article shares stories told during a participatory scenario planning process among Inuit, an Indigenous People of northern Canada, Greenland, and Alaska, USA. This research takes place in Nunatsiavut, a land claim area in Labrador, Canada, to explore how visions provide insights into postcolonial futures for the fishing industry. Beginning in 2019, a group of fisheries stakeholders and managers came together to create a visioning process that would help them to develop consensus around priorities for the industry. Facilitated by university researchers, Inuit in the commercial fishing industry participated in an iterative data-collection process that involved interviews and a workshop. This article shares what was found during the scenario-planning process and position stories of the future within the context of Indigenous sovereignty. [ABSTRACT FROM AUTHOR]

The operating efficiency of fishermen's associations is significant for developing the fishery industry and fishing villages. Since fishermen's associations have economic, financial, and service sectors, this study evaluates their efficiency through multiactivity data envelopment analysis. In addition to exploring the overall efficiency of each fishermen association, this study further investigates the differences in the operating efficiency of each of the economic, financial, and service sectors. Fishermen's associations were divided according to their sizes and geographic areas for analyses and comparisons by considering the differences in their organizational scales and fishing activities. In the empirical study, 24 fishermen associations in Taiwan were selected as the research subjects, and the shared inputs of economic, financial, and service sectors were taken to conform to their practical operation. The overall efficiency of fishermen's associations was affected by their size and mainly varied by economic sector. The research results indicate room for improvement in the overall efficiency of fishermen's associations, but improving the efficiency of different fishermen's associations should occur in various sectors.

Summary: The liquid by‐products obtained from the fisheries industry are usually discarded after primary processing. In this study, by‐products of pressure‐cooked milkfish broth were utilised and combined with Gracilaria sp. to create sustainable seaweed stick snacks. By utilising the by‐products of liquid waste from pressurised milkfish processing, combined with the addition of Gracilaria seaweed in snack development, it is expected to obtain a snack products with increased protein and fibre level. This endeavour contributes to the achievement of the Sustainable Development Goals (SDGs), particularly in promoting good health and well‐being, as well as responsible consumption and production. Comprehensive analyses were performed, covering proximate composition, dietary fibre, functional group, thermal properties, colour, microstructure, pore size, viscosity, texture, and sensory evaluation through hedonic testing and check‐all‐that‐apply sensory (CATA) profiling. The FTIR results showed that the inclusion of seaweed and fish broth was recognised and presented in the specific characteristic bands, especially the stretching band in the polysaccharide fingerprint region, and with protein vibration bands blending with the inclusion of broth. The seaweed had an impact on the dough viscosity and product's texture, increasing the firmness, and the amino acids in the broth enhanced the taste of the resulting snack, positively influencing the panellists' preferences. The smoothness, moistness, roughness, and overall texture attributes of the snack were altered by the combination of seaweed and broth additions. According to the sensory, physical properties, and nutrient results, the optimal snack formulations included the addition of 36% seaweed and 4% broth (S36B4). The prominent sensory attributes of the product were also described in the CATA sensory evaluation. Additionally, the inclusion of Gracilaria sp. increased the dietary fibre content, while milkfish broth contributed to higher levels of amino acids, improving the nutritional profile of the snacks. Therefore, this study promoting a new source of protein could be synergistically combined with marine plant‐based fibre to produce hybrid nutrient‐dense snack products, addressing the growing demand for sustainable food trends.

The history of freshwater fish production and consumption in Thailand were reviewed in the late 1970s. While aquaculture had a history of more than a century in the country it had only started to expand relatively recently because of the abundance of wild fish in former times. Historical aspects of freshwater capture fisheries and freshwater aquaculture in Thailand, and the development of irrigation in Central Thailand which played an important role in facilitating the development of inland aquaculture in the country were reviewed. While dam construction led to the demise of the flood plain capture fishery, it provided a controlled water supply necessary for the subsequent development of aquaculture. The study informed the development of education and research in aquaculture at the Asian Institute of Technology (AIT). More recent developments in Thai aquaculture are outlined. Malnutrition in developing countries and fish in the Thai diet at the time of the study were also reviewed. [ABSTRACT FROM AUTHOR]

This paper aims to analyze ASEAN's role in addressing forced labor exploitation in the fisheries industry in Indonesia through the ASEAN Ministerial Meeting in Transnational Crime (AMMTC) framework. The exploitation of workers in fisheries has emerged as a problem in the fisheries and seafood industry in Indonesia, although several international conventions have been made and ratified, its handling is complicated by the challenges of vested interests. The seafood supply chain is one of complex global value and involves a variety of sources including the use of workers who are vulnerable to deception and coercion in their recruitment and employment. The role of ASEAN as a regional organization is very influential in solving this problem and it requires compact cooperation between international organizations and governments to jointly handle it. This research raises the question "Why has the ASEAN cooperation mechanism not been able to reduce the level of exploitation of ship workers in Indonesian waters?". To find out and explain the research question, the concept of international organization will be used. [ABSTRACT FROM AUTHOR]

Offshore oil and gas platforms support abundant reef fish and are popular fishing sites for recreational anglers. However, the rapid decommissioning and removal of active platforms have decreased such fishing opportunities in the Gulf of Mexico, raising concerns about fisheries impacts. Conversely, planned offshore energy structures like wind turbines may offer similar habitats and fishing sites. To inform spatial planning for marine energy infrastructure in the context of recreational fisheries, we created models of fish communities associated with oil and gas platforms using existing abundance data. We employed Random Forest analysis to predict the presence‐absence and abundance of Red Snapper (Lutjanus campechanus) and Greater Amberjack (Seriola dumerili) at platforms using 47 environmental and platform variables. Nonmetric multidimensional scaling on Bray−Curtis dissimilarities explored fish species composition among 37 species. Results showed variability in Red Snapper and Greater Amberjack incidence/abundance from shore to shelf‐edge, not attributed to surrounding habitat or climatological oceanographic variables. Incidence models were more robust than abundance models. Fish species composition was significantly influenced by location gradient, with less impact from other habitat features. Our findings guide selecting areas for artificial structures to enhance angler opportunities and maintain fish diversity, but identifying the drivers of finer scale abundance variation will require further sampling.

As the world’s capacity for plundering the ocean for food grows, our ability to know what level of fishing is sustainable isn’t keeping pace. Officials in charge of preventing overfishing [...]

The fishing gear deployed by fishermen in seas and oceans throughout the world not only captures target species but also unintentionally ensnares non‐target species, a phenomenon known as ‘by‐catch’. This unintended capture of marine life can represent significant challenges for the fishing industry, with adverse impacts on both the environment and species such as sea turtles, marine mammals, seabirds and elasmobranchs, which may be injured or even killed. To address this problem, the fishing industry has implemented regulations and mitigation measures. In this literature review, we have examined 389 papers published between 2010 and 2022 that assess the effectiveness of these measures. Taking into account the fishing gear with which each group interacts the most, trawls for sea turtles, gillnets for marine mammals and longlines for seabirds and elasmobranchs, it has been demonstrated that ‘TEDs’ (Turtle Excluder Devices) are an effective measure for sea turtles, ‘pingers’ for marine mammals and ‘BSLs’ (Bird Scaring Lines), more commonly known as ‘tori lines’, for seabirds. The most complex case is that of elasmobranchs, and the most effective measure has yet to be discovered. This complexity arises from the ongoing targeted fishing of these species, resulting in less monitoring of their catches and, therefore, fewer surveys. Overall, we encourage the global implementation of these measures by the fishing industry in order to reduce by‐catch in an attempt to ensure the future of many endangered species.

Seafood plays an important role in sustainably feeding the world and is one of the most traded food products globally. However sustainability improvements are often focused on its production (e.g., aquaculture, fishing) rather than trade. Here, we quantify the magnitude and extent of global 'redundant two-way' seafood trade–the exchange of the same quantity of the same taxonomic species between two countries–to examine its prevalence and potential implications across the seafood supply chain. We focused on wild-caught seafood trade and found that redundant two-way trade has increased by 43%, between 2000 and 2015, making up 3.2% (7.7 Mt) of global seafood trade during that period. Although most countries were involved in redundant two-way seafood trade (111 of 212 analyzed), the majority occurred between five trade partners: Canada and the United States (15%), Germany and the Netherlands (11.8%); Denmark and Sweden (10.6%); Germany and Denmark (7.1%); and France and Norway (7%). Nearly 50% of redundant trade is made up of just four species including Atlantic herring, Atlantic cod, Skipjack tuna and Atlantic mackerel. While deficiencies in global seafood trade data mask seasonal and product heterogeneity, redundant trade could have implications for meeting conservation and sustainable development goals. Future research should build upon these findings to explore specific environmental, economic, and social implications associated with redundant two-way trade to benefit producers and consumers within the seafood supply chain.

Our study examines the condition of sustainable development in Omani fisheries industry, with specific focus on the extent to which the fishing companies practice sustainable fishing that meets the objective of food security. We also detect, characterize, and analyze the compliance of the fishing companies with the principles of social, economic, and environmental sustainability. Using 55 completed questionnaires of 70 surveyed operating fishing companies, a multivariate general linear model was used to determine the impact of economic and environmental factors on achieving sustainability, and domestic demand of fisheries sector in Oman. Our results revealed that more than 63% of companies believed that sustainability is extremely important in the fisheries industry, and around 42% of the companies 'strongly agree' that Oman meets its domestic demand from its own harvest. The model displayed significant effects of the amount of production for local consumption, climate change adaptation, and water waste management on improving sustainability of the fisheries sector. Analysis also confirmed significant effects on the amount of production for local consumption, amount of production for export, and using technology to locate stock on enabling the country to meet its domestic demand through its own harvest. We conclude by arguing that our findings have important implications for managing production in terms of food security and safeguarding domestic consumption. [ABSTRACT FROM AUTHOR]

In recent years, smart fisheries, as an emerging model for fishery development, have become a research hotspot in the fishery and aquaculture industries of many countries. Smart fisheries can be thought of as a system that combines techniques for raising, catching, or selling aquatic products to improve production and sustainable development. Smart fisheries are crucial to improving fishery and aquaculture management. In this study, a comprehensive analysis was conducted using bibliometric analysis, the results of which are presented through visual mapping and data charts. This study collected data from the China National Knowledge Infrastructure (CNKI) database and compared it with the WoS database. A total of 949 articles were retrieved on topics related to smart fisheries, including 579 articles from WoS and 370 articles from CNKI. The results present the visualization and analysis of annual publications, author collaboration maps, research collaboration institutions, keywords, etc. The development of smart fisheries in China is obviously different from that in foreign countries. China attaches great importance to technology and production, while foreign countries focus on environmental issues. Therefore, this study helps us to understand the current research status, research hotspots, and future development directions of smart fisheries, providing certain references for future management.

Eighty years ago, George S. Myers classified inland fishes in three divisions (primary, secondary and peripheral) based on their salinity tolerance and eco‐evolutionary history. Although this classification has been followed by many fish studies, it has also received considerable criticism. Here, we aim to test for differences in salinity and thermal tolerance, species traits and distribution patterns among the three divisions using data for about 21,000 species. We found that primary fishes have much less salinity tolerance than secondary and peripheral species, with some secondary fishes displaying the highest tolerances (>100 ppt). We also provide, for the first time, evidence of significant phylogenetic signal of salinity tolerance, comparable in magnitude to conservative traits, and show that studied peripheral and secondary species have maintained or even developed salinity tolerance, in contrast to primary fishes. Although peripheral fishes are the most different, and despite the large variability observed within some families, primary and secondary species also show differences in morphology and life‐history traits. The distribution ranges and genetic diversity of primary and secondary fish divisions are similar and differ from peripheral species, suggesting that although there is evidence of oceanic dispersal of a few secondary fishes at evolutionary time scales, it is a rare contemporary phenomenon. Importantly, a few findings outlined in this study, namely, differences in salinity tolerance, rely on limited data. Thus, we urge for additional empirical research on the salinity tolerance of freshwater fish, which remains largely unexplored, to help clarify differences among and within clades.

Pacific salmon (Oncorhynchus spp.) spend much of their life near the ocean surface where climatic and oceanographic conditions affect their habitat and survival. Despite decades of study, critical knowledge gaps persist regarding their ecology and distributions. Consequently, it has been difficult to assess how environmental conditions influence the high‐seas distribution and habitat use of these culturally and socioeconomically important fishes, presenting challenges to fisheries managers trying to evaluate how climate change and fishing activities may impact salmon populations. We used a recently compiled, comprehensive database of historical coastal and high‐seas salmon survey data (1953–2022) in the North Pacific to fit species distribution models that (1) characterize the marine spatial distribution of six species of Oncorhynchus, (2) evaluate species‐specific temperature preferences, and (3) investigate how species' temperature preferences influence distribution. Sea surface temperature, along with seasonal migrations associated with spawning and feeding, significantly affects the distribution of all species, where the warm limits of estimated preferred thermal ranges were more similar than the cold limits. Furthermore, the distributions of some species appear more responsive to temperature than others and recently observed warm conditions have likely impacted realized ranges. These models have expanded our understanding of salmon ocean distributions and thermal niches by providing a unique window into this often unobserved but important part of the life cycle. They also serve as a baseline for future investigations into the mechanisms influencing salmon spatial ecology, responses to climate change, and vulnerability to harvest across the North Pacific.

In comparison to the wealth of critical evaluation of LEADER (i.e., Liaison entre actions de développement de l'économie rurale), there has been no consolidated attempt to reflect on the contribution of Fisheries Local Action Groups (FLAGs), now entering their third EU programming period. Set up in the image of LEADER, and a novel governance instrument within the Common Fisheries Policy (CFP), FLAGs aim to activate local responses that build resilience and adaptability within the fisheries sector and wider communities. In addition to introducing the accompanying articles that make up this special issue of Sociologia Ruralis, our article gives an account of the emergence of community‐led local development (CLLD) in fisheries and the attributes that have characterised the application of the LEADER approach within a fisheries‐territorial development context. In many cases, FLAGs have led to improved relationships between the small‐scale fishing sector and wider local social and economic networks, helping the sector reimagine its role within local economies. Yet outcomes vary as the FLAG approach has been applied across different cultural and institutional settings. There are indications that the system is becoming enveloped by wider priorities of coastal development and blue growth. Yet FLAGs may well provide a successful test case for widening participation in the CFP and upscaling integration of the fishing industry within local and regional economies. For CLLD in general, they are a reminder of the value of a differentiated CLLD approach tailored to different sectoral‐territorial contexts. [ABSTRACT FROM AUTHOR]

In European Union member states, the community‐led local development (CLLD) approach implemented through Fisheries Local Action Groups (FLAGs) represents different social organisational and democratic traditions. Hence, FLAGs operate and apply local development strategies and strengthen the role of fishing communities and the fishing industry under the influence of nationally contingent factors. Based on document analysis and mixed methods data, this article addresses the role of input legitimacy in FLAGs in Denmark and Finland. The findings show that Danish FLAGs demonstrate input legitimacy, while the fishery sector's interests are relatively weakly represented on FLAG boards. In Finland, the FLAG institutional system is perceived to be more flexible, demonstrating a lower level of input legitimacy, while the fishery sector's interests are substantially represented on FLAG boards. The comparison provides an analytical basis for member states financing CLLD through EMFAF and paves the way for reflexion on the FLAG governance system based on different programming periods and institutional contexts.

The main objective of this study was to investigate whether the intraindustrial trade structure of the Turkish fisheries sector has been affected by global climate change. Therefore, the surface temperatures of the Black Sea, Marmara, Mediteranean and Aegean seas and the Grubel-Lloyd index values related to the sector for the period 1985-2017 were used as variables in the study. The Auto-Regressive Distributed Lag (ARDL) bounds test was used to determine the cointegration relationship between variables and to predict longterm coefficients. The Error Correction Model (ECM) method was used to determine the short-term coefficients. According to the results of the analyses: (i) There is a long-term relationship between the variables; (ii) Increases in the surface temperature of the Aegean, Mediterranean and Marmara seas have reduced intra-industrial trade in the long-term; (iii) The increase in the Black Sea surface temperature has increased intra-industry trade in the long-term; (iv) The increase in sea surface temperatures has shown a tendency to increase intraindustry trade from the southern seas towards the northern seas in Turkey. Consequently, global climate change can be considered as a change in intra-industry trade for both the country and the industry. [ABSTRACT FROM AUTHOR]

Introduction of the concept of surimi was a boon to the fish processing industry. Tremendous development in the surimi processing technology not only increased the export, but also upgraded the local fish products industries in many countries including Thailand, Malaysia, India, etc. Surimi a wet concentrate of myofibrillar protein, which is washed, partially dehydrated, additives added, blocks prepared, frozen stored and used for preparation of surimi products. Thus, making surimi products available throughout the year without fresh fish supply. Surimi production industry is rapidly growing its production capabilities to meet the increasing demands. In India many surimi factories are producing tropical fish surimi & 99% of it is exported. Various ready to cook (RTC) surimi products are produced, but production of ready to eat (RTE) surimi products is comparatively less. Surimi was prepared from mackerel Rastrelliger kanagurta & was used for preperation of 2 surimi products crunchy noodles and crispy chips, which can be safely consumed upto 3 weeks.

Purpose: While the literature has highlighted the impacts of COVID-19, there is limited evidence on the gendered determinants of the impact of COVID-19 among small-scale rural traders in developing and emerging economies. Design/methodology/approach: Cross-border fish traders who had operated before and during the COVID-19 pandemic were interviewed in a survey conducted in Zambia and Malawi. Logistic regressions among male and female traders were employed to assess the gendered predictors. Findings: Heterogeneous effects in geographical location, skills, and knowledge were reported among male cross-border traders. Effects of household structure and composition significantly influenced the impact of COVID-19 among female traders. Surprisingly, membership in trade associations was associated with the high impact of COVID-19. Research limitations/implications: Due to the COVID-19 pandemic and the migratory nature of cross-border fish traders, the population of cross-border fish traders at the time of the study was unknown and difficult to establish, cross-border fish traders (CBFT) at the landing sites and market areas were targeted for the survey without bias. Originality/value: This paper addresses a gap in the literature on understanding gendered predictors of the impacts of COVID-19 among small-scale cross-border traders. [ABSTRACT FROM AUTHOR]

Fiordland National Park is a UNESCO site located in the remote, southwest of New Zealand's South Island, which attracts hundreds of thousands of visitors every year. One of its leading attractions is Milford Sound. An oil spill in this area could not only impact the industries that operate in Milford Sound but also impact all of the park. To improve the knowledge base about this area in regard to oil spills and policies regarding ship visitation, this study aimed to estimate the costs of clean‐up, impacts to fisheries, tourism, recreation and the wildlife/environment under three oil spill scenarios in Milford Sound. Minimum costs are estimated at NZD 140–154 million. These results demonstrate the need for proper planning and response measures, and appropriate domestic and international policies to help minimise the potential damages that may occur in the event of an oil spill in a remote and pristine area of New Zealand.

Spexin (SPX, NPQ) is a 14-amino acid neuroactive peptide identified using bioinformatics. This amino acid sequence of the mature spexin peptide has been highly conserved during species evolution and is widely distributed in the central nervous system and peripheral tissues and organs. Therefore, spexin may play a role in various biological functions. Spexin, the cognate ligand for GALR2/3, acting as a neuromodulator or endocrine signaling factor, can inhibit reproductive performance. However, controversies and gaps in knowledge persist regarding spexin-mediated regulation of animal reproductive functions. This review focuses on the hypothalamic-pituitary-gonadal axis and provides a comprehensive overview of the impact of spexin on reproduction. Through this review, we aim to enhance understanding and obtain in-depth insights into the regulation of reproduction by spexin peptides, thereby providing a scientific basis for future investigations into the molecular mechanisms underlying the influence of spexin on reproductive function. Such investigations hold potential benefits for optimizing farming practices in livestock, poultry, and fish industries. [ABSTRACT FROM AUTHOR]

Simple Summary: Marine aquarium keeping is a popular hobby that fuels a global industry that still heavily relies on the sourcing of wild organisms, mostly from tropical coral reefs. The European Union (EU) is one of the largest import markets for marine ornamental fish. Despite being mandatory and already fully digital, the record-keeping of what species are imported in what numbers from which exporting countries remains blurry. The present work presents curated and consolidated data reporting the value, the exporting and importing countries, and the number of specimens, species, and families of marine ornamental fish imported to the EU between 2014 and 2021. A 24-million-euro annual trade value was recorded, and 26 million specimens were imported from more than 60 countries (mostly Indonesia, the Philippines, and Sri Lanka). A watchlist is presented to provide guidance to stakeholders on which marine ornamental fish species being traded most likely require closer monitoring due to their potential impact through trade. The European TRAde Control and Expert System (TRACES) requires some minor tunning to enable authorities to easily monitor the imports of marine ornamental fish into the EU, thus allowing an unprecedented insight into this and other trade activities targeting wildlife. Wild-caught fish from coral reefs, one of the most threatened ecosystems on the planet, continue to supply the marine aquarium trade. Despite customs and veterinary checks during imports, comprehensive data on this global industry remain scarce. This study provides consolidated data on the largest import market by value, the European Union (EU): a 24-million-euro annual trade value, detailing the main exporting and importing countries, as well as the species and families of the 26 million specimens imported between 2014 and 2021. A watchlist alert system based on the number of specimens traded, import trends, and vulnerability index according to FishBase and the IUCN Red List conservation status is presented, providing key information on which species should require closer scrutiny by authorities. While the European TRAde Control and Expert System (TRACES) electronically monitors the movement of live animals to respond quickly to biosecurity risks, one-third of marine ornamental fish imported lack species-level information. With minor adjustments, TRACES holds the potential to significantly enhance data granularity and the monitoring of wildlife trade, with marine ornamental fish being an interesting case study to validate this approach.

At present, catch statistics in the pelagic fishery industry rely mainly on manual counting methods. However, this method suffers from low statistical accuracy and insufficient timeliness. An automatic tuna counting approach based on ByteTrack and YOLOv7-Tuna is presented in this research. The method selects YOLOv7 as the base model, adopts DySnakeConv to obtain more temporal features, combines it with CoordConv to enhance the location-awareness ability of the model, and introduces DyHead to suppress the interference of complex backgrounds. The experimental results show that YOLOv7-Tuna outperforms YOLOv7 in terms of precision by 5.2%, recall by 3.1%, mAP@0.5 by 0.5%, and mAP@0.5:0.95 by 10%. Furthermore, the ByteTrack algorithm was employed to achieve real-time tracking of targets, with specific counting areas added. The results indicate that the counting error of this method decreased to 3.1%. It can effectively accomplish automatic counting tasks for tuna, providing a new solution for the automatic quantification of catch in the offshore fishing industry. [ABSTRACT FROM AUTHOR]

The amount of by-products/waste in the fish industry is roughly 50%. Fish bones could be used to produce nanoparticles, which may have potential use in the food industry as a novel calcium source and at the same time, contribute to reduce waste production. The objective of this study was to evaluate the bioavailability of nano-size salmon fish bone particles compared to micro-size salmon fish bone particles, and calcium carbonate. The study was carried out in 21–28-day-old C57BL/6 male mice fed for 21 days with the experimental diets. The groups were as follows: CaCO3 0.5% Ca (CN 0.5); CaCO3 1.0% Ca (CN 1.0); salmon fish bone (SFB) microparticles 0.5% Ca (MP 0.5); SFB microparticles 1.0% Ca (MP 1.0); SFB nanoparticles 0.5% Ca (NP 0.5); and SFB nanoparticles 1.0% Ca (NP 1.0). Calcium bioavailability, defined as the percent calcium in femur showed an increasing trend from CN 0.5 to NP 1.0 group. According to ANCOVA, the greatest Ca content was observed in the NP 1.0 group compared with all groups but NP 0.5. In conclusion, in a murine model, salmon fish bone nanoparticles present higher calcium bioavailability than salmon fish bone microparticles, and both, in turn, have better bioavailability than calcium carbonate.

Flavobacterium psychrophilum, the causative agent of bacterial cold-water disease, is a devastating, worldwide distributed, fish pathogen causing significant economic loss in inland fish farms. Previous epidemiological studies showed that prevalent clonal complexes (CC) differ in fish species affected with disease such as rainbow trout, coho salmon and ayu, indicating significant associations between particular F. psychrophilum genotypes and host species. Yet, whether the population structure is driven by the trade of fish and eggs or by host-specific pathogenicity is uncertain. Notably, all F. psychrophilum isolates retrieved from ayu belong to Type-3 O antigen (O-Ag) whereas only very few strains retrieved from other fish species possess this O-Ag, suggesting a role in outbreaks affecting ayu. Thus, we investigated the links between genotype and pathogenicity by conducting comparative bath infection challenges in two fish hosts, ayu and rainbow trout, for a collection of isolates representing different MLST genotypes and O-Ag. Highly virulent strains in one host species exhibited low to no virulence in the other. F. psychrophilum strains associated with ayu and possessing Type-3 O-Ag demonstrated significant variability in pathogenicity in ayu, ranging from avirulent to highly virulent. Strikingly, F. psychrophilum strains retrieved from rainbow trout and possessing the Type-3 O-Ag were virulent for rainbow trout but not for ayu, indicating that Type-3 O-Ag alone is not sufficient for pathogenicity in ayu, nor does it prevent pathogenicity in rainbow trout. This study revealed that the association between a particular CC and host species partly depends on the pathogen's adaptation to specific host species. [ABSTRACT FROM AUTHOR]

This study investigated the biology, population parameters, and ecology of the sergestid shrimp (Acetes) in Barangay Damilisan, Miagao, Iloilo, the Philippines, by collecting samples for biological analyses and analyses using FiSAT II software. Based on morphometric evaluation, the sergestid shrimps present in the study site were identified as Acetes intermedius. Mature and near-spawning of the 180 specimens examined for ovarian maturity were > 50% in January, February, and April 2022. Size at sexual maturity was recorded at lengths ranging from 21.90-23.10 mm. The highest mean TL and CL were 20.49 ± 1.84 and 5.32 ± 0.56 mm, respectively, in January 2022. The length-frequency data showed that the highest frequency was 18.50-20.40 mm. The male-to-female sex ratio was 1:2; wherein females dominated the males. The highest frequency for females ranged from 20.50-22.40 mm (TL). Estimated population parameters of A. intermedius were L∞ = 30.98 mm, K = 1.900 yr-1, Ø' =3.26 yr-1, tmax= 1.6 yr-1, M = 3.93 yr-1, F = 4.07 yr-1, Z = 8.00 yr-1, E = 0.51, E0.1 = 0.517, E0.5 = 0.349, Emax = 0.691, L50%/Lc = 13.45 mm, and L75% = 14.57 mm with a unimodal type of recruitment pattern. The value obtained for the exploitation rate was above 0.5, hence suggesting that the Acetes stocks in Brgy. Damilisan faced overexploitation. These results provide information that can be used to properly conserve, utilize, and manage the Acetes fishery industry in Miagao, Iloilo, the Philippines. [ABSTRACT FROM AUTHOR]

An assessment on the fluctuations in abundance of the striped venus clam (Chamelea gallina) in the southern Adriatic Sea (Central Mediterranean Sea), and the northern Gargano area, has been conducted through both historical information and recent data from monitoring surveys during the period 1997–2019. Production trends, conditions of the commercial stock biomass, and depth distribution pattern of juveniles and commercial sizes were analysed testing temporal differences. Moreover, the exploitation of the clam beds and recruitment events were investigated in 2018–2019. Changes in abundance were analysed using non-parametric tests for both juvenile (length class, LC < 22 mm) and commercial (LC ≥ 22 mm) fractions. Hydrodynamic changes, temperature and salinity variations were explored using a 3D hydrodynamic numerical model (MIKE 3 FM-HD) and statistical analysis, as well as changes in benthic assemblages impacted by hydraulic dredges were investigated through PERMANOVA and other multivariate analysis. The results showed a temporal decline of production and biomass of C. gallina during the 1997–2019 period, and a regression of the depth limit in the clams' distribution towards shallower waters. A significant reduction in juveniles was observed during 2018–2019 with a very limited recruitment. The fishing exploitation showed high impacts on the commercial stock and benthic assemblages in the summer of 2018. Overall, water currents were predominantly directed offshore in 2018, during the C. gallina spawning period. This could affect the larval dispersal and settlement on unsuitable bottoms. Anomalies in temperature (high peaks in August 2018, > 28 °C) and salinity (low values in spring 2018, < 37 PSU) could have induced stress and mortality events on the entire clam bed in the study area. This first study highlights the need to integrate environmental information in the assessment of commercial stocks of clams in the Adriatic Sea, to better understand climate change effects on the fluctuations and to support effective ecosystem-based fishery management.

A global analysis of the functional characteristics of meta-assemblages of estuary-associated fishes was undertaken at the marine ecoregion level. Marine ecoregions were grouped into broad biogeographic regions (bioregions) and functional attributes of the fish assemblages compared based on a numerical fish estuary association score, as well as estuarine use functional groups. Relationships between selected environmental characteristics and fish functional attributes were also examined. A significant relationship between ecoregion environmental variables and estuarine fish functional assemblages was recorded, with the key environmental factors identified being related to habitat (estuarine area and macrophyte vegetation), connectivity (mean annual runoff), and physico-chemical (sea surface temperature and sea surface salinity) variables.

Kenya is a major player in the global ornamental trade, exporting substantial quantities of ornamental fish to the global market. The sector plays an important role in the country's economy through foreign exchange. However, the country's ornamental fish industry has not fully developed to generate more economic benefits. This paper sought to identify the existing opportunities for enhancing the production and trade of ornamental fish in the country. The findings reveal that there are opportunities for collection of native freshwater ornamental fish species from the vast freshwater resources in the country; for the culture of marine ornamental fish; for public aquariums as centres of recreation, conservation, research and education; and for employment and development of support industries. The findings also show that there are international legislations and national policies that create an enabling environment for the growth of the industry. To unlock the full potential of the industry, training and research, investment and infrastructure development, quality assurance, collaboration and networking, and environmental sustainability strategies need to be put in place. This will ensure Kenya's position as a key player in the global ornamental fish trade. [ABSTRACT FROM AUTHOR]

A fishing industry value chain model identifies production, distribution, and marketing stages that enhance the value of fishery products. It aids in cost breakdown, process optimization, and gaining a competitive advantage. The study links activities from fresh fish to smoked fish, tracking the entire process to the final consumer and identifying all involved actors. Quantitative and qualitative methods analyze data, determining production costs, selling prices, added value, and ratios in each distribution channel. Findings reveal six key players in the smoked fish value chain: fishermen, wholesalers, traders, processors/IKM, retailers, and consumers. Fishermen, wholesalers, and traders supply raw materials to processors/SMEs, which act as both producers and distributors. Retailers sell directly to consumers. Significant added value, exceeding 40%, suggests ample potential for growth in the smoked fish industry. The value chain model holds implications for fisheries in small islands with abundant natural resources, promoting increased efficiency, business sustainability, improved quality, social sustainability, enhanced added value, market development, monitoring, supervision, and strategic planning. Some policy recommendations from this study are expected to create a conducive environment for business sustainability, improved product quality, and added value in the smoked fish industry, as well as provide positive benefits to local communities and maintain market order.

Simple Summary: Fish fry counting finds applications in various scenarios, including fish fry trading and the management of breeding densities. However, current computer-based methods struggle to accurately and effectively count large numbers of fish fry and locate them. To address these challenges, this study proposes a fish fry counting method based on a single keypoint as a feature. Additionally, a large-scale fish fry dataset, FishFry-2023, has been constructed, which includes universal point annotations for use. The number of fry in a single image ranges from 204 to 1935, ensuring an effective evaluation of the proposed method. Our approach was trained and tested on FishFry-2023, with experimental results demonstrating an average counting accuracy of 98.59%, exhibiting higher counting precision compared to the density map algorithms now available. Fish fry counting has been vital in fish farming, but current computer-based methods are not feasible enough to accurately and efficiently calculate large number of fry in a single count due to severe occlusion, dense distribution and the small size of fish fry. To address this problem, we propose the deconvolution enhancement keypoint network (DEKNet), a method for fish fry counting that features a single-keypoint approach. This novel approach models the fish fry as a point located in the central part of the fish head, laying the foundation for our innovative counting strategy. To be specific, first, a fish fry feature extractor (FFE) characterized by parallel dual branches is designed for high-resolution representation. Next, two identical deconvolution modules (TDMs) are added to the generation head for a high-quality and high-resolution keypoint heatmap with the same resolution size as the input image, thus facilitating the precise counting of fish fry. Then, the local peak value of the heatmap is obtained as the keypoint of the fish fry, so the number of these keypoints with coordinate information equals the number of fry, and the coordinates of the keypoint can be used to locate the fry. Finally, FishFry-2023, a large-scale fish fry dataset, is constructed to evaluate the effectiveness of the method proposed by us. Experimental results show that an accuracy rate of 98.59% was accomplished in fish fry counting. Furthermore, DEKNet achieved a high degree of accuracy on the Penaeus dataset (98.51%) and an MAE of 13.32 on a public dataset known as Adipocyte Cells. The research outcomes reveal that DEKNet has superior comprehensive performance in counting accuracy, the number of parameters and computational effort. [ABSTRACT FROM AUTHOR]

As described by the temperature–size rule paradigm, fish living in warmer temperatures grow faster but have a smaller mature body size. However, the changes in the body size of fish communities in the western North Pacific, which is one of the most active fishing grounds, remain unclear. This study aimed to investigate changes in the body size of fish assemblages in the western North Pacific and whether fish sizes were potentially driven by the temperature–size rule, bottom‐up effects and intra‐ and interspecies competition at a community scale. We evaluated the fish weight data of 6 stocks of 4 species from 1978 to 2018 and 17 stocks of 13 species from 1995/1997 to 2018. Weight reduction in the fish assemblage was observed in the 1980s and was associated with the biomass peak of the Japanese sardine (Sardinops melanostictus), indicating the effect of intra‐ and interspecies competition. Another weight reduction was observed in the 2010s, which was associated with a moderate increase in the biomass of the Japanese sardine and chub mackerel (Scomber japonicus). Our analyses indicate that stronger stratifications in the surface layers during the 2010s potentially reduced the nutrient supply from the subsurface to the surface layers. This limitation in food availability forced intra‐ and interspecies competition under a moderate increase in fish biomass. Our findings underscore the critical significance of integrating the impacts of species competition and climate change on fish sizes to improve fishery management at a community level.

The role of vegetated habitats such as seagrass and macroalgal beds as nurseries is essential for the survival of larval and juvenile fish, although quantitative evaluation of the contribution of these habitats to nursery function is limited. Moreover, growth–survival relationships of larvae and juveniles associated with vegetated habitats have rarely been examined. To quantitatively and qualitatively evaluate the processes affecting juvenile survival in vegetated habitats, we investigated whether there is a correlation between the degree of selection for bigger and faster‐growing fish and mortality rates for three cohorts by birth date of post‐settlement black rockfish (Sebastes cheni) in a macroalgal bed. We also analyzed relationships between growth rate and experienced temperature by age class to examine the effects of temperature on growth. The latest cohort, which grew under lower vegetation coverage due to a seasonal increase in water temperature, showed higher mortality with evidence of strong selection for survival of bigger and faster‐growing fish. The growth–temperature relationships showed that positive effects of temperature on growth weakened after settlement. Therefore, we suggest that macroalgal coverage has a critical role in controlling the growth–mortality relationship of post‐settlement S. cheni. Furthermore, the negative effects of high temperature on juvenile survival through loss of vegetation may be greater than the positive effects on juvenile growth. These findings would contribute to the management of fisheries resources by increasing the understanding of relationships between survival mechanisms in fish early life stages and vegetation phenology of their habitat under the increasing effects of global warming.

Many oceanic species in pelagic habitats move vertically through the water column, highlighting the ecological importance of that spatial environment for modeling habitats of marine species. The role and importance of multiple oceanic subsurface environmental variables in modeling the habitat suitability of swordfish (Xiphias gladius), a highly migratory large pelagic fish, is poorly understood. In this study, we analyzed adult swordfish data from the 2017–2019 Chinese Indian Ocean tuna longline fishery observer. We used the maximum entropy model (MaxEnt) and random forest model (RF) to compare modeling schemes that included multiple subsurface environmental datasets. The area under receiver operating characteristic curve (AUC) from training and test sets was evaluated to investigate whether the inclusion of subsurface variables could enhance model performance and affect the simulation results. This analysis showed that model performance was significantly enhanced after addition of subsurface environmental variables, and the best model fit was achieved at 200–300 m depth. Sea water temperature, dissolved oxygen, net primary production, and ocean mixed layer depth were the critical environmental factors constituting catchability for swordfish in the Western Indian Ocean. As the depth increased, dissolved oxygen became the most important environmental factor, replacing surface temperature. Compared with the surface model, the location and extent of areas of high catchability in certain months changed significantly after the addition of subsurface variables. The results of this study provide evidence for a better understanding of the selection of critical environmental variables and improvement of model performance in 3D habitat modeling of pelagic fish.

Sustainability after the creation of the Bui Dam has been problematic, with the Bui Power Authority (BPA) addressing the environmental, economic, and social concerns related to sustainability. As a result, electricity generation and irrigation are managed to ensure long-term social, economic, and ecological sustainability. The study thus aims to advance societal progress by analysing the impacts of social, economic, and environmental sustainability on both current and future generations, focusing on the concerns of reservoir stakeholders. Approaches used were Formal Surveys guided by semi-structured interviews, Focus Group Discussions (FGDs), and Key Informant Interviews (KII). Qualitative and quantitative data were collected and analysed using the Statistical Package for Social Scientists (SPSS). Evidence showed that fish capture, processing, and trade were critical economic activities that sustained residents and impacted their economic, social, and cultural well-being. Fishers operated daily with unapproved and destructive gear such as hook-and-line traps and beach-seine nets, which were detrimental to the sustainability of the fisheries. The fishing pressure (1,500 fisher population and 2,000 canoes) was hostile towards the sustainability of fishing in the reservoir. Recommendations were to restrict the reserved reservoir component, establish local fish catch monitoring stations, and build local fisher folk capacity to gather critical monitoring information.

Bryozoan epibiosis on lobster hosts has rarely been reported. This study documents bryozoan fouling of the American lobster (Homarus americunus Milne Edwards, 1837) from the Connecticut portion of Long Island Sound, USA. A total of 168,664 lobsters were examined for epibionts from 2000 to 2013 following the lobster fishery crash in 1999. The lobsters were caught commercially for the State of Connecticut. Department of Energy and Environmental Protection lobster catch monitoring program. The lobster shell condition in four stages of its molt cycle was noted (i.e., from a soft new shell, hard new shell, hard shell, to ready to molt). Of the lobsters caught, 29% were fouled by epibionts. Of those, 88% were fouled by bryozoans, 20% by barnacles, 6% by tube worms, 3% by slipper shells, and KEY WORDS: lobster, Bryozoa, epibiosis, Atlantic, Hamulus umericunus, INTRODUCTION Epibiosis has referred to the ecological association between organisms growing attached to a living surface such as the bryozoans on the lobsters in this study.
