ABSTRACT Fishery discards worldwide increase the availability of organic materials on the benthos, altering trophic relationships and potentially increasing the abundance of benthic consumers. Expert knowledge from fishers is a valuable yet often underutilized source of information to understand these dynamics. We interviewed Dungeness crab fishers (n = 24) to determine the most‐used bait types and to characterize regional and seasonal bait use strategies that drive inputs of organic matter into Oregon coastal waters during the commercial Dungeness crab fishery each year. Based on bomb calorimetry measurements of caloric densities of 12 commonly reported bait species, total energetic input was 12.99 × 109 kJ (3.10 B kcal) from bait in the 2019–2020 commercial ocean Dungeness season in Oregon, USA. Fishing effort and bait inputs were strongly seasonal, with 88% of effort concentrated in the first 60 days of the 9‐month‐long season but did not vary regionally. This large, temporally concentrated caloric input suggested that bait could contribute substantially to Dungeness crab productivity. Fisher respondents indicated that bait effectiveness was the most important motivating factor in choosing a bait type, more than availability or cost. [ABSTRACT FROM AUTHOR]

Recent studies have documented poleward shifts in heavily targeted fish stocks on the Bering Sea Shelf. This study investigated whether commercial fishing vessels in the region have also shifted their distribution poleward in recent years. We used Vessel Management System data generated between January 1, 2013, and December 31, 2022, to identify regions over the shelf where vessel activity increased (emerging hot spots) and where it decreased (emerging cold spots) during this time period. We hypothesized that emerging hot spots would occur at the northern edge of the vessel operating range, while emerging cold spots would occur at the southern edge. Overall, northward shifts in vessel distribution were most evident during October–February and July–August, when the range of emerging hots spots was centered 204–515 km to the N, NE, or NW of the center of the range of emerging cold spots. The trend was strongest in August, when emerging hot spots were widespread in the Northern Bering Sea. We did not attempt to identify factors driving these distributional shifts, but the timing of shifts did coincide with the busiest fishing seasons over the Bering Sea Shelf and, in part, the open seasons for walleye pollock (Gadus chalcogrammus). If groundfish populations continue to move poleward with climate change, this study may serve as a window into the early stages of a long-term redistribution of commercial fishing effort in the Bering Sea, a region supporting one of the largest fishing industries in the world.

This article provides perspectives on the graying of the fleet and research efforts to understand it in Alaska fisheries, discusses recent abrupt multifaceted challenges faced by Alaskan fishermen, and compares divergent public perceptions and support programs for farmers and fishermen in the United States. Equity concerns have seen a resurgence in academic and policy realms and the graying of the fleet is now a common example of distributional inequity, yet despite in-depth research attention on the issue, few substantive programmatic modifications have been made to address it in Alaska. Aging trends in United States fisheries have typically been framed as one of changing aspirational preferences. Research suggests coastal youth do desire and highly value fishing careers, but structural and financial barriers limit opportunities for new generations. The precarity of the fishing industry was highlighted in 2023 with sudden global seafood market instability, rising interest rates and operating costs, destabilized geopolitical tensions, and hastening climate change impacts. This recent industry turmoil disproportionately impacts those on the margins and adds an additional layer of complexity to addressing graying of the fleet trends. Unlike in fisheries, there are numerous federal programs to support young farmers and the agricultural industry. This paper calls for proactive and comprehensive measures to stabilize and support fishing communities and the viability of next generation pathways amidst recent fishing industry market turmoil and longer term inequities in fishery governance.

Through commercial fishing, harvesters face elevated physical and financial occupational risk. We examine harvesters' utilization of health insurance to mitigate risk, drawing data from over 2,800 survey responses from US West Coast commercial fishing vessel owners from 2017 and 2020. Respondent health insurance coverage is compared with census county-level Small Area Health Insurance Estimates. We also explore drivers of obtaining health insurance using logistic regression, categorizing drivers as corresponding to either costs or benefits of insurance. Despite elevated occupational risk, we find empirical evidence that health insurance coverage for West Coast commercial vessel owners is lower than the general population of their county-level communities. Respondent health insurance uptake is also found to be primarily driven by variables associated with costs rather than benefits of health insurance, providing evidence against strong adverse selection. These insights provide potential mechanisms for management regimes that could benefit well-being in fishing communities. [ABSTRACT FROM AUTHOR]

We used isodars, developed from the ideal free distribution (IFD), to predict the distribution of fishing effort across regulatory boundaries in the south-western Scotian Shelf’s haddock fishery. Our analysis was focused around the boundary between Northwest Atlantic Fisheries Organization’s Divisions 4X and 5Z. While effort within 4X was related to the standardized catch value and effort experienced along the 4X–5Z boundary, most effort predictions across the boundary were also accurate. Accuracy of these cross-boundary isodars suggests that a high degree of movement across the boundary meets the IFD assumption of free movement and thus, effort on one side of the boundary is related to fishing success on the other side of the boundary. Fisheries management strategies should adopt a broad view that encompasses adjacent regulatory regions to understand where vessels may choose to fish when multiple regulatory regions are accessible. In fisheries where isodars describe effort distributions across a regulatory boundary, the relative abundance of the underlying fish population could be better indicated by effort distribution among regulatory regions than by catch rates.

There is very little information on Andean condors scavenging on fish. Here we report five events of condors feeding on fish carrion in the Bolivian Chaco Serrano in three consecutive years. In 2019, 2020, and 2021, condors were observed feeding on discarded fish from local fishermen, 3 km west of Villa Montes, in the 'El Angosto' section of the Pilcomayo River. Fishing, mainly for sábalo (Prochilodus lineatus), is the most important economic activity in that part of the Pilcomayo basin and its discards explain fish carrion availability there, while driving scavengers to feed on this resource. We believe that fish carrion abundance, the intensity of intra‐ and interspecific competition for access to carrion, and overall carrion availability hierarchically influence the fact that condors feed on fish, something we will investigate later based on the observations reported here. From a conservation perspective, the main consequence of scavengers feeding on fish from the Pilcomayo is that they could be getting heavy metal poisoning. Heavy metal poisoning is a serious threat with widely known negative effects for wildlife. Our observations should serve to promote comprehensive bio‐monitoring of the Pilcomayo basin, using approaches such as One Health, and emphasizing the importance of coexistence between humans and the rest of biodiversity, with the Andean Condor as the flagship species.

The goal of this exploratory pilot study was to reduce marine fatalities in Norton Sound using knowledge shared from Alaska Native salmon set gillnetters in Unalakleet, AK. The following objectives to address this goal were: 1) identify factors that influence safety for Alaska Native commercial set gillnetters in Norton Sound; 2) use findings from objective 1 to improve commercial fishing training, education, and resources; and 3) disseminate and communicate results from objective 1 to commercial fishers in the Norton Sound fleet, commercial fishing safety partners, and the Alaska Native injury prevention community. Ten semi-structured interviews were conducted with Alaska Native commercial set gillnetters in Unalakleet, AK. We utilized knowledge shared to identify factors that influence safety for their fleet. Using an Interpretative Phenomenological Analysis Methodology, 10 interviews were recommended for a homogenous sample. Most participants learned to fish at a young age from the family, with safety lessons passed on by family members. Fishing is a lifestyle and interconnected with harvesting and a way of living. Set gillnetters in Norton Sound use open skiffs and have limited access to workable Personal Flotation Devices (PFDs) and safety training. Participants reported health benefits but also negative long term physical effects, financial stress, and difficulty fishing with age. Respect and awareness of the ocean was reported as the most important strategy to reduce risk. Stories were shared of falls overboard, capsizing, and local fatalities and hazards, such as being overloaded with fish, entanglement, and maneuvering a small boat in large waves. Stronger winds and shifting weather patterns were experienced from climate change. This exploratory pilot study identified factors that influence safety for Alaska Native commercial set gillnetters. Findings should be used to 1) determine best methods to influence behaviors to reduce risks in this hazardous fishery; 2) increase awareness and promote expanded application of best practices, equipment, and resources; 3) encourage and promote outreach initiatives targeted for this unique population; and 4) develop tailored training programs for commercial fishing in an open skiff. Research with Alaska Native fishing communities will require value and respect of indigenous knowledge, collaboration with local people, and follow-up to bring findings back to the community.

Occupational fatality rates in the commercial fishing industry in the United States remain more than 20 times higher than the national average. The burden of commercial fishing fatalities due to unintentional falls overboard is highest in the Gulf of Mexico (GOM) shrimp fishery. The objective of this quasi-experimental, pre-/post-test project design was disseminating recovery slings to GOM captains/deckhands, training in their use, and assessing the attitudes, beliefs, and intentions of fishermen in their adoption. Due to the COVID−19 pandemic, a land-based simulation was used to train commercial fishermen at three port locations in use of crew overboard (COB) recovery slings. A survey was developed to assess the attitudes, beliefs, and intentions of commercial fishermen in COB recovery. Purposive sampling was employed to recruit 30–50 fishermen at each location. Following pre-/post-training surveys, fishermen received one recovery sling per vessel along with a task list of instructions for use of the sling. A third survey and task list questions were performed at 12–18 months. There were 119 recovery slings and training in their use provided to 123 commercial shrimp fishing vessel owners/captains and deckhands along the Texas and Louisiana Gulf Coast. Repeated measures analysis of variance of the three surveys showed that positive change in normative beliefs was significant for the importance of quickly and safely maneuvering the vessel to the crew member. This change was most significant over the period from the initial training and receipt of the recovery sling by the vessel captain/deckhand, to the time of follow-up 12–18 months later (p =.03). Regarding control beliefs, training was associated with immediate statistically significant improved confidence that, with assistance, the fisherman would be able to use the sling and other equipment to hoist the COB (p =.02). However, this confidence waned significantly over time (p =.03). Attitudes and beliefs of commercial fishermen in the GOM can be favorably influenced toward a COB recovery device, as well as their confidence, and intention to use such devices. However, results show that attitudes and beliefs may wane over time, emphasizing the importance of repeated training and survival drills in this industry. [ABSTRACT FROM AUTHOR]

Introduction: Workers in physically demanding jobs with high injury rates, long hours, productivity pressures, and lack of job security, such as commercial fishing, are at higher risk for substance use and misuse. In the United States, the federal government is urging employers to consider having naloxone available to reverse the effects of an opioid overdose, especially in workplaces. This study examined naloxone training, naloxone availability, and level of concern over substance use in commercial fishing. Methods: As part of a larger study of commercial fishing vessel captains, we asked participants how worried they are about various potential problems, including substance use by crew members, using a five‐point scale. We also asked whether they had completed naloxone training and whether their vessel was equipped with naloxone. Results: Of the 61 vessel captains who participated, 10 had naloxone training. Most were "not at all worried" about a crew member misusing alcohol (n = 52; 85.2%), a crew member using marijuana (n = 50; 82.0%), a crew member using other drugs (n = 49; 80.3%), or a crew member having a drug overdose (n = 52; 86.7%). Only five fishing vessels were equipped with naloxone. Conclusion: Our results indicate that few fishing vessels are equipped with naloxone or have captains trained in its use. Fishing captains tend not to be worried about substance use in their crew. Given the higher rate of overdose deaths in the fishing industry compared to other industries, having more vessels equipped with naloxone and captains trained to administer it could save lives.

Regarded as gourmet food, lobster is one of the main fisheries in Mexico and Yucatan, a state that specializes in the production of lobster tail for the national tourism market (Cancun). Using the theoretical positioning of the Spatial Organization of the Economy and a methodology that combines qualitative and quantitative data, this investigation reveals the complex interrelationship between different spaces (fishing, processing, and consumption zones) generated by the Yucatecan lobster economy. However, the current spatial structure could be modified by the incipient catch of live lobster, driven by new actors and directed to the international market (China). [ABSTRACT FROM AUTHOR]

At this time East Asian river prawn Macrobrachium nipponense is present almost everywhere in the lower reaches of the Danube and Dniester basins, in the Danube-Dniester interfluves and water bodies to the east of the Dniester. Successful adaptation and favorable climatic conditions in recent years have provided a signifi- cant increase in the East Asian river prawn populations in the Danube and Dniester. High growth rates of M. nipponense have been observed in the Danube and Dniester. In these river basins, higher values of maximum body length of the prawn (males 115 mm, females 87 mm) than those recorded in the native range water bodies and the cooler water bodies of thermal power plants during introduction were recorded. In small shallow brackish-water reservoirs of the region (PSU 1.5-6.0) the growth rate of M. nipponense is significantly lower than in the freshwater Danube and Dniester deltaic zones. Female East Asian river prawn in such water bodies mature at a much smaller size. The egg-laying period of female M. nipponense in the Danube lasts from June to October. The peak of egg laying is observed in July and August. There have been reported cases of M. nipponense being affected by crustacean burn-spot disease. The prospect of organizing the fishing of M. nipponense in the Danube River has been determined. It is necessary to continue research to increase selectivity of fishing gears, determination of optimal terms of fishing, and places of installation of fishing gears. [ABSTRACT FROM AUTHOR]

As ocean conditions continue to be altered by climate change, California’s fishing industry and fisheries management must adapt and find new ways of progressing into the future. California’s waters support valuable economic resources for both food security and job stability. Because of this, new state fishing regulations seek to provide opportunities to both the fishing industry and fisheries managers while protecting the future of these valuable marine resources. Assembly Bill 1573, the California Fisheries Innovation Act of 2018, set standards for creating a formalized and expansive Experimental Fishing Permit (EFP) Program that would promote collaborative research in exploring emerging or underutilized fisheries and testing new or modified fishing gear types through conservation engineering across both the recreational and commercial fishing industry sectors. The new California EFP Program, expected to begin in 2021, stands to have great success in fostering fisheries collaboration, sustainability, scientific research, and more adaptive fisheries management strategies. However, there are regulatory hurdles, prohibitive costs, and barriers to collaboration that should be addressed before the program begins.The following Capstone Report provides background research for the new EFP Program by investigating past successful federal Exempted Fishing Permits, the current California box crab EFP, potential future California EFP projects as well as the expected benefits and limitations of the permit program. The intention of this project is to assess state research needs and prepare the EFP Program for successful implementation in 2021. In the concluding section of the report, recommendations are made for the EFP Program procedural guidelines which will be drafted by the California Department of Fish and Wildlife later this year.

Lake whitefish (Coregonus clupeaformis) is an ecologically and commercially significant species across the Laurentian Great Lakes. Over the past 20 years, lake whitefish population abundance has substantially declined across lakes Huron and Michigan, being driven by reduced recruitment of juvenile fish into the population. However, the life stage at which the recruitment bottleneck is occurring and what factors are contributing to the declines remain unknown. One hypothesis is that dreissenid mussels reduced zooplankton availability to larval lake whitefish, leading to poor growth and survival of this critical life stage. Here, we present results of a larval fish survey conducted at the Fishing Islands spawning region in Lake Huron and examine whether declines in juvenile recruitment are linked to reduced larval fish density. Larval fish were collected annually during two time periods: (1) a historical time period before dreissenid mussel establishment (1976–1986); and (2) a contemporary time period after dreissenid mussels became established (2017–2019, 2021). We found significant declines in larval densities and growth between historical and contemporary time periods. Following dreissenid establishment, larval densities and growth were on average only 23% and 55% of historical values, respectively. Moreover, year class strength at the juvenile stage (age 4) was positively related to larval density. Several explanatory variables contributed to annual variation in larval densities, with dreissenid mussels and water levels having the most consistent effect. Our results suggest that juvenile recruitment is being limited at the larval stage, owing to overall lower larval production and potentially exacerbated by slower growth. [ABSTRACT FROM AUTHOR]

Context: The western rock lobster fishery is recognised to be conservatively managed, with breeding stock levels estimated to be at record levels over the past decade. Despite this, anecdotal reports from commercial fishers identified an area of unexpectedly low catches in the centre of the fishery and lobsters' biogeographic distribution. Aim: To confirm the presence of this suspected 'low-catch' zone and examine the variability in catch and growth rates of lobsters if identified. Methods: This study conducted an intensive mark–recapture survey over 8 months to explore catch rate, density, movement and growth rates across this 'low-catch' zone and three comparable locations. Key results: In total, 9318 lobsters were caught and 7565 individuals were tagged during the study. Consistently low catch rates of under-sized lobsters were observed in the 'low-catch' zone, with catch rates increasing with distance from the zone. By contrast, similar catch rates of legal-sized lobsters were observed across all locations. Conclusions: The study confirmed low catch rates, for under-sized lobsters, within an area of perceived low catch rates within the centre of the fishery. The lack of difference found in legal-sized catch rates among locations is likely to be due to the low fishing pressure in the 'low-catch' zone, resulting from hyperstability of fishers adapting to the historical perceived low catch rate. Modelled data demonstrated the 'low-catch' zone to be associated with faster growth rates and high fine-scale migration, indicating a potential release from density-dependent processes. Implications: We anticipate that these results will be a useful starting point for future research into the mechanisms responsible for the unexpectedly low catch of sublegal lobsters within the 'low-catch' zone and the implications it may have on the wider population, both regionally and across the species distribution. The Western Rock Lobster fishery is recognised to be a conservatively managed fishery. However, anecdotal reports from commercial fishers identified an area of unexpectedly low catches. This study conducted an intensive mark–recapture survey over 8 months to explore this low-catch zone. We found a decreased abundance of sublegal lobsters, but consistent abundance of adults, indicating a hyper-stability of fishing catches, owing to fishers adapting to perceived low catch rates. This study provides a valuable baseline for further research. [ABSTRACT FROM AUTHOR]

Recreational fishing is common around the Mediterranean Sea. The number of recreational fishers is growing, and they are using increasingly efficient fishing techniques. However, fisher activity is heterogeneous, both temporally and spatially, making it very difficult to determine this sector's fishing pressure and annual yields. Therefore, estimates of annual yields and ecological effects of this fishing sector are limited. In this study, we undertook an extensive survey designed to document and quantify recreational fishing patterns across the Israeli Mediterranean shoreline. We comprehensively quantified recreational fishing using three complementary strategies: (1) ground surveys, including interviews with anglers on the coast, (2) personalized phone interviews, and (3) aerial surveys by helicopter. These methods were used to calculate annual recreational yield and to estimate species and size composition, which were then compared to the commercial fishing catch. We found that a recreational catch makes up between 10%-37% of the total annual fishing yields, which is similar to estimates from other regions of the Mediterranean. We also found that non-indigenous species are among the most common species in recreational catch and have become a significant part of local fishery yields. Recreational angling from the coast targets smaller, reef associated species compared to recreational fishers at sea. We identified 23 species common to both recreational fishing and commercial fishing, over which conflicts between fishing sectors may arise. These results can be used to more accurately manage Israeli fisheries and can provide a baseline against which to compare future changes in a region under the threats of climate change, biological invasions, and growing human pressure.

Fishing makes a fundamental contribution to food, services, leisure, commerce and of course the economic well-being of the population, whether it is for present or future generations, and must be managed in a responsible manner. The purpose of this paper is to present the quantitative and qualitative dynamics of the structure of commercial marine catches of Romania in the period 2008 - 2021. Also, an analysis was carried out regarding the volume of catches made against the total allowable catches (TAC), established by annual orders. The raw data presented in this paper are obtained from the official website of the National Agency for Fisheries and Aquaculture. Until 2017, the catches in the Black Sea had an upward evolution, after which they had a downward trend. The dominant species in catches is the rapana snail (Rapana venosa) (90.78%), followed by sprat (Sprattus sprattus) (2%), mussels (Mytilus sp) (1.8%), anchovy (Engraulis encrasicolus) (1.38%).

From data published by the Hong Kong SAR (HKSAR) government in their two sole fisheries surveys of 2006 and 2016/2017, the current authors produced regional maps using spatial interpolation to more accurately describe and estimate the geographic coverage of changes in fishing production in Hong Kong waters since the ground trawl ban of 2012 December 31st. These suggest the fishing industry has adapted to smaller craft, and that fishing production increased in several areas in the period after the ground trawl ban came into effect. In addition, the maps enable a smoother assessment to be made of the geospatial changes in fishing production which have occurred since the ground trawl ban and suggest a ‘workaround’ by fishermen. In particular, small fishing craft known as sampans are able to take advantage by being more suitable vessels for areas such as narrower or shallower bays. Marine plastics pollution is also a proxy indicator of these activities, as evidenced by discarded fishing gear that includes plastic nets, floats, and other fishing boat equipment.

Fishing and fish consumption have historically been marked by criteria of social distinction. The historical inequalities between those who consume noble fish and those who consume other more popular fish tend to revolve around the question of the freshness of the product and the quality of the fisherman's work, considered as a singular kind of artisan. The economic and ecological injunctions tend to still be linked to a capitalist grid of vision of the world, and this article aims at deconstructing them. I use ethnography to understand how food morals and food justice are at stake along the fish supply chain. [ABSTRACT FROM AUTHOR]

Background: Mobile apps addressing a variety of workplace safety issues have proliferated over the last decade as mobile technology has advanced and smartphone ownership has increased. Workplace safety interventions are often designed for a specific work site. However, some of the most dangerous jobs are ones in which workers frequently change field locations, such as commercial fishing. Mobile apps may be particularly suitable for delivering safety interventions to these workers. Objective: We sought to gauge the potential for using mobile apps to deliver safety interventions to commercial fishing workers. The purpose of this paper is to describe how fishermen use their mobile devices during fishing operations and identify any mobile apps they already use for safety. Methods: Participants comprised commercial fishing captains who already owned an iOS or Android smartphone or tablet. They completed a questionnaire that asked about their current mobile device use and their use of safety-related mobile apps, in addition to questions about their fishing operations. We performed descriptive analyses of the data. Results: A total of 61 participants completed the questionnaire. The most common types of mobile devices participants reported owning were iPhones (n=36, 59%) and Android phones (n=24, 39%). Most participants (n=53, 87%) reported using their mobile device for both work and personal purposes, including while out at sea (n=52, 85%). Over half of the participants reported that they had either safety-related apps (n=17, 28%) or apps that help them with their work (n=35, 57%). The types of apps most frequently mentioned were apps for weather, wind, tides, and navigation. Conclusions: The results of this study indicate that some commercial fishing captains who own a mobile device are receptive to using safety-related apps for work. Apps that help avoid hazards by monitoring environmental conditions and apps optimized for use on smartphones may be most likely to be adopted and used. Overall, these results suggest that mobile apps are a promising avenue for improving safety among workers in commercial fishing and similar occupations. [ABSTRACT FROM AUTHOR]

Introduction: Agriculture, forestry, and fishing industry (AgFF) workers often work extremely long hours during peak production seasons, resulting in sleep deprivation and fatigue. The National Occupational Research Agenda has classified fatigue as a "significant safety issue" and area of concern for many industry sectors, including AgFF. This review explores current research and practice in AgFF and proposes next steps. Methods: We conducted a scoping literature review to examine the extent and nature of research in this area. Article inclusion criteria included peer‐reviewed journal articles written in English; published after 1989; covering AgFF workers in high‐income countries; with data on working hours/schedules and sleep related to safety and health. Results: Limited research has addressed long hours and sleep deprivation among AgFF workers. We identified 8350 articles for title and abstract review. Among those, 407 underwent full‐text review and 96 met all inclusion criteria (67% agriculture, 25% fishing/seafood processing, 8% forestry). The literature provided some evidence fatigue contributes to fatalities, injuries, and illnesses in AgFF. Older, new, young, foreign‐born, and female workers, as well as those who work in small organizations or longer hours (40+) may be at higher risk for fatigue‐related injury and illness. Few studies have developed or evaluated interventions to control risks. Discussion: Given that fatigue is a factor in injury and illness for this sector, future AgFF surveillance and research should increase efforts to capture fatigue and sleep data, directly investigate the role of long hours and nonstandard work schedules in the sector, and most importantly, create practical interventions to manage fatigue.

Background and Aims: Advisory boards play a key role in guiding and informing research programs, including occupational health surveillance. It is important to evaluate the effectiveness of these advisory boards. This report details the organization of the Risk Information System for Commercial (RISC) Fishing Technical Advisory Board (TAB), the approach taken to evaluate the TAB, and the results of the evaluation. The RISC TAB was formed to provide advice and recommendations to the study team and informed the development and use of the safety surveillance system. Methods: The evaluation approach was informed by limited previous literature on advisory board assessments. This evaluation was conducted in Year 5 of the 6‐year project. A review of the meeting notes, materials and correspondences, and study progress was conducted internally to document input from the board and associated actions. To obtain member perspectives, we surveyed the TAB and discussed it in a subsequent TAB meeting. Results: The RISC Fishing TAB members constitute a wide variety of commercial fishing safety stakeholders. The internal analysis identified the main project aspects and 14 of the proposed changes from the TAB that have either been implemented or are in progress in the project. Ten of the 15 TAB members responded indicating a positive experience on board organization and conduct. Conclusion: Evaluation of advisory boards is an essential part of a research program. A process is outlined in this report to inform future efforts to document measurable ways to inform projects based on advisory board feedback and reflections. [ABSTRACT FROM AUTHOR]

The lobster-harvesting industry has a high occupational injury incidence compared to land-based industries. Participatory ergonomics methods were used to partner with lobstermen to develop and implement ergonomic improvements. The model included training in ergonomics principles, a forum for ergonomics discussions, and a sequence of meetings planned to focus on problem identification, intervention, evaluation, and dissemination of findings. One crew initiated 3 specific actions: the introduction of a conveyor belt to assist material handling at a local lobstering pier, the installation of a star block at the space for hauling traps onto the boat, and the initiation of a design process for improved mechanical assistance for hauling traps onto the boat. The other crew took action to reduce force and postural exposures by creating a short video intended to disseminate ergonomic ideas to other lobstermen. The influence of important cultural norms was observed for future research and development in the community. [ABSTRACT FROM AUTHOR]

The advancement of conservation practices in global trawl fisheries has been impeded in part by a lack of a collective understanding of the most relevant and broad-scale knowledge-needs, along with the identification of potential barriers to addressing these knowledge-needs. Using both an online survey and an in-person workshop, we engaged a diversity of fishing industry stakeholders including scientists, technology companies, trawl net makers, and fishermen working with North Pacific, United States, trawl fisheries to identify and prioritize areas in which further knowledge is required for successful implementation of conservation engineering practices. In addition, we identified barriers to addressing these knowledge-needs. Knowledge-needs related to fishing gear performance were identified among the top priorities, including several areas targeted at improving fishing efficiency that could further advance the sustainability of well-managed trawl fisheries. To better understand the composition and behavior of target versus non-target catch, workshop participants identified the importance of closing data and technology gaps. This highlights areas for potential collaboration between fishermen, researchers, and technology companies to address research prioritized by the end-user. Further, results from the workshop emphasized a need for industry-driven training and workshops focused on elevating fishermen skill for newer entrants through peer-learning and knowledge-sharing to achieve objectives like better non-target avoidance and increased fishing efficiency of the target species. Addressing these prioritized knowledge-needs, by first working toward overcoming the industry-identified barriers, may aid in increasing uptake of conservation practices, thereby contributing to the long-term sustainability of these fisheries and associated social-ecological systems.

These results can be used to more accurately manage Israeli fisheries and can provide a baseline against which to compare future changes in a region under the threats of climate change, biological invasions, and growing human pressure.

Crucial point of fishery management is to let the fish or other species reproduce at least once during their life. Therefore it is very important to determine the length at maturity (Lm) for given species before the first capture. Focus of this study is to determine the consistency between scientific results and minimum landing size (MLS) regulations in the marine fishery of Turkey. For this purpose, 4/1 communique on commercial fishery (2016/35) published by the Republic of Turkey Ministry of Agriculture and Forestry was investigated in order to expose the MLS of given species in Turkey. Literature survey on Lm was also conducted preferably on studies which were performed in Turkish waters or from the Mediterranean basin in order to avoid regional differences. While 86 marine species were reported to be landed in the official fishery statistics, only 49 of them were appointed with a MLS in the commercial fisheries regulation. It was determined that MLS of 27 species were below the Lm according to the selected literature, 7 of them require result on Lm, status of the 2 species couldn’t be decided due to different length types and 13 (27% of the decisions on MLS) of them were found to be in accordance with the scientific literature on Lm. This study shows that MLS regulation must be revised for most of the species in the surrounding waters of Turkey and comprehensive maturity studies are urgently needed in order to fulfill the scientific gap.

The opioid epidemic has had disproportionate effects across various sectors of the population, differentially impacting various occupations. Commercial fishing has among the highest rates of occupational fatalities in the United States. This study used death certificate data from two Massachusetts fishing ports to calculate proportionate mortality ratios of fatal opioid overdose as a cause of death in commercial fishing. Statistically significant proportionate mortality ratios revealed that commercial fishermen were greater than four times more likely to die from opioid poisoning than nonfishermen living in the same fishing ports. These important quantitative findings suggest opioid overdoses, and deaths to diseases of despair in general, deserve further study in prevention, particularly among those employed in commercial fishing.

The implementation of large-scale marine protected areas (MPAs) depends upon scarce conservation resources, while their effects on biodiversity conservation are rarely assessed to date. Quantitative evaluations are necessary to assess the effectiveness of large-scale MPAs in enhancing ecosystem resilience, protecting biodiversity, and mitigating expanding threats. In this study, the effectiveness of large-scale MPAs, which are remotely managed and in offshore areas of the southwestern Atlantic Ocean (Brazil), was assessed concerning the occurrence of fishing activities within their boundaries before and after their implementation. Two sets of MPAs surrounding the São Pedro and São Paulo archipelago (SPSP) and the Trindade-Martin Vaz Islands (TMV) were established in early 2018, each comprising one no-take (i.e., fully-protected) and one multiple-use (i.e., partially-protected) area. For this assessment, I used satellite detections of Vessel Monitoring System transmission to quantify the fishing pressure (i.e., “likely fishing days”) from commercial fisheries spanning 5 years (2015–2019). I then derived three metrics – fishing area, intensity, and density – to compare fishing activity within each MPA and year. The results showed that the effectiveness of the multiple-use MPAs was variable and contrasting, with SPSP experiencing a reduction in the fishing intensity and area and TMV experiencing an increase in both measures. An inverted pattern was evident for the no-take MPAs: while the one in the SPSP region experienced an increase in the fishing density after its establishment following a squeeze factor, the no-take MPA in the TMV region observed a decrease in the fishing density when comparing years before and after MPA implementation. These outputs can support managers in planning the implementation of further conservation strategies, such as monitoring and enforcement plans, and the analyses here also contribute to enhancing our understanding on the implications and challenges of adopting large-scale MPAs in the offshore environment as a high-profile strategy of ocean conservation.

Whether you’re an angler, diver, conservationist, or just interested in fisheries, you’ve likely heard the term “stock assessment” before. What are stock assessments? How do they work? How do they inform management decisions? This publication provides information to the public and people serving in natural resource management agencies and working in outreach and Extension to show how fisheries management decisions are made.

Commercial fishing has played a critical role in the economy of the different islands of the Atlantic Ocean and those in the Canarian Archipelago in particular. In fact, one of the motives behind the European colonization of the Canaries was to exploit the fishing grounds of the Saharan Bank to satisfy part of the nutritional needs of a European population in constant expansion from the late Middle Ages. Fishing in the Canary Islands between the sixteenth and eighteenth centuries was essential as it served both an internal and an external market, and was a key factor in the development of the Canarian economy. During the Ancien Régime, the mobilization of people and resources in the fishing sector produced protein for a growing population. The fishing industry therefore offered a highly profitable protein-rich product at a low price. Although fishermen from a number of European countries, notably France, England and Peninsular Spain, fished the oceanic waters around the Canary Islands, most of this activity was carried out by Canarians.

Background: Commercial fishing is the most hazardous occupation in the United States. While the epidemiology of adult injuries and fatalities are well documented, injuries to children (<18 years old) are not described. The purpose of this report was to describe the characteristics of nonfatal injuries to children involved in commercial fishing. Methods: Nonfatal commercial fishing injuries to children were identified in the Alaska Fishermen's Fund. The Alaska Fishermen's Fund is an emergency fund payor of last resort. Data on nonfatal injuries to victims aged 17 or younger were analyzed. Descriptive statistics were used to characterize demographics and injury characteristics. Results: Forty‐four nonfatal child injury claims were made between 2012 and 2016. The mean age at the time of claim was 15.6 years (SD = 1.8) and 84% were male. The most common types of injuries among children were sprains and strains and the most commonly injured body parts were upper extremities and the trunk. Most injuries occurred in salmon fisheries. Conclusions: Children are participating in commercial fishing. Based on the results of this analysis, children are also experiencing occupational injuries. The results of this analysis underscore the need for additional safety and health information, guidance for supervisors, and intervention to prevent injuries to children participating in commercial fishing.

Large marine protected areas (MPAs) of unprecedented size have recently been established across the global oceans, yet their ability to meet conservation objectives is debated. Key areas of debate include uncertainty over nations' abilities to enforce fishing bans across vast, remote regions and the intensity of human impacts before and after MPA implementation. We used a recently developed vessel tracking data set (produced using Automatic Identification System detections) to quantify the response of industrial fishing fleets to 5 of the largest MPAs established in the Pacific Ocean since 2013. After their implementation, all 5 MPAs successfully kept industrial fishing effort exceptionally low. Detected fishing effort was already low in 4 of the 5 large MPAs prior to MPA implementation, particularly relative to nearby regions that did not receive formal protection. Our results suggest that these large MPAs may present major conservation opportunities in relatively intact ecosystems with low immediate impact to industrial fisheries, but the large MPAs we considered often did not significantly reduce fishing effort because baseline fishing was typically low. It is yet to be determined how large MPAs may shape global ocean conservation in the future if the footprint of human influence continues to expand. Continued improvement in understanding of how large MPAs interact with industrial fisheries is a crucial step toward defining their role in global ocean management. Article impact statement: Large marine protected areas in intact ecosystems may have positive conservation effects and low immediate impact on industrial fisheries. [ABSTRACT FROM AUTHOR]

The purpose of the Fishing CommunitiesProject was to provide detailed historical and current social science information on four Northern California port communities – Crescent City, Trinidad, Eureka/Fields Landing, and Noyo/Fort Bragg. In addition to profiling each community, the project also provides a regional overview that encompasses the three counties – Mendocino, Humboldt, and Del Norte – in which these communities are situated. While this report is intended to help address fishery management needs, it can be used in a range of processes, from local planning and education to state and regional policy issues.

Sustainable natural resource management requires collaboration, adaptability and coordination between science, policy and stakeholders. Communication of scientific information through social networks is integral to effective governance. This study employed social network analysis to investigate information flow between stakeholders associated with the blue swimmer crab (Portunus armatus) fishery in the Peel-Harvey Estuary, south-western Australia. Although the fishery received Marine Stewardship Council certification in 2016, a preliminary study conducted between 2017 and 2018 revealed that fishers were concerned about its status and management. Consequently, 85 face-to-face interviews were conducted with commercial and recreational fishers, academics, government bodies, representatives of fishing organizations, non-governmental organizations, and tourism operators to understand the flow of information and the influence on perceptions of sustainability. The results showed that: (i) few individuals were key for sharing information within and between different organizations forming the fishery network and only two of the six groups (government bodies and the commercial fishing sector) were highly connected and appeared as key for information sharing; (ii) after the public awareness and tourism groups, academic groups were the second-least connected, despite having actively researched the Peel-Harvey Estuary and the P. armatus fishery for over 40 years; (iii) recreational fishers exchanged information mainly with other fishers and the state fisheries department; (iv) modes of communication used with the recreational fishing sector differed greatly between the fisheries department (i.e., mainly via phone/email) and the recreational fishing organization (i.e., strong online presence, social media, and phone/email); (v) issues of inclusiveness and representativeness were highlighted for some of the groups and organizations. This is the first study looking at information-sharing patterns through an Australian fishery network. Through this research we have identified logistical and institutional challenges to communicating information regarding the science, management and environmental issues related to a small-scale crab fishery and made suggestions to enhance information flow in the network.

Understanding the drivers of exploited fish abundance distributions is key to successful natural resource management, but it is costly to obtain this information at large spatio-temporal scales relevant to management. We used small programmable automated cameras (POTBots) deployed in commercial rock lobster fisher’s pots, during normal fishing activities, across ∼750 km of the west coast of Australia (10–120 m deep), to test for relationships between the relative abundance of fishes and both environmental (habitat composition, swell, depth and water temperature) and anthropogenic factors (recreational and commercial fishing effort). Among the six most frequently observed fishes, the abundances of two targeted species, Choerodon rubescens and Epinephelides armatus, were negatively correlated with an index of recreational effort, although this was confounded by the natural abundance distribution of these species along the west coast. For example, a unimodal abundance distribution with latitude was observed for C. rubescens, matching its known distribution. In contrast, the abundances of the commercially important Chrysophrys auratus and Lethrinus miniatus were positively correlated with an index of commercial effort, reflecting the expectation that commercial fishers typically would target areas of greatest abundance that produce higher catches per unit effort. The abundances of two non-target species, Coris auricularis and Neatypus obliquus, were correlated with expected environmental variables (water temperature, depth, habitat composition and swell) but neither recreational nor commercial fishing effort. All but one of these reef species had a strong positive relationship with reef cover, as expected, and three species exhibited a negative relationship with swell. We have developed a highly cost-effective fisheries-independent monitoring tool to understand relationships between species abundance distributions and major environmental and anthropogenic factors. It is easily deployed using existing pot or trap fishery infrastructure and is therefore highly applicable to both developed and developing countries.

This article is designed to provide the methodologies used to estimate the impact to the commercial fishing industry as a result of spatial zone management changes within Florida Keys National Marine Sanctuary and its study area, Monroe County, FL. The analysis provided here provides a template for how to estimate economic impacts when refined human use spatial data are not available. Utilizing existing habitat maps and economic data, this method downscales traditional economic methods using a spatial approach to match the fine-scale management approach utilized by the National Marine Sanctuary System. This approach allows the authors to estimate the economic impacts to the commercial fishing sector. The authors find that the proposed spatial zone changes may result in an estimated loss of 42 jobs, with 28 being harvester jobs, to the state of Florida. Additionally, $4.1 million in output and approximately $1.1 million in income may be lost. These estimates do not take into account the likelihood of substitution to alternative fishing grounds or adjusting the target species.

This commentary provides an overview of the impact of COVID-19 on the commercial fishing industry. The information highlighted in the article was gathered from fishermen, fishing industry experts, health and safety advisors, and advocates. From these first-hand accounts, we provide the immediate and expansive impacts of COVID-19 on fishermen's health and wellbeing. In particular, we discuss the economic impact of COVID-19 market disruptions, as well as the very real, logistical challenges of protecting workers on fishing vessels. We also provide examples of how these combined issues have led to increased occupational risk in one of the nation's most deadly industries. Lastly, we identify a number of recommendations for providing much-needed support for commercial fishermen in light of the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Invasive bigheaded carps, genus Hypophthalmichthys, are spreading throughout the Mississippi River basin. To explore the efficacy of a consumer-based market (i.e., invasivorism) to manage them, we developed a conceptual model and evaluated three harvest approaches--direct contracted removal, volume-based incentives ("fisher-side" control), and set-quota harvest ("market-side" control). We quantified the efficacy of these approaches and potential population impact in the Illinois River. Contracted removal was effective for suppressing small populations at the edge of the range but cannot support a market. "Fisher-side" removals totaled 225,372 kg in one year. However, participation was low, perhaps due to reporting requirements for fishers. The "market-side", set-quota approach removed >1.3 million kg of bigheaded carp in less than 6 months. Larger, older fish were disproportionately harvested, which may hinder the ability to suppress population growth. Total density declined in one river reach, and harvest may reduce upstream movement toward the invasion fronts. With sufficient market demand, harvest may control bigheaded carp. However, lack of processing infrastructure and supply chain bottlenecks could constrain harvest, particularly at low commodity prices. Given the geographical scale of this invasion and complicated harvest logistics, concerns about economic dependence on invasivorism that encourage stock enhancement are likely unmerited.

Interactions between fishing vessels and oil and gas infrastructure can result in damage to fishing gear, loss of fishing time/access, and risks to crew health and safety. The spatial and temporal patterns characterizing previous incidents (and subsequent losses) between fishers and oil and gas infrastructure were quantified and used to identify key risk factors associated with fisheries losses. Between the years 1989 and 2016, 1590 incidents that resulted in a financial loss, vessel abandonment, or an injury/fatality for UK commercial fishers were recorded. The annual number of recorded incidents decreased by 98.6% over a 27-year period. The majority of past incidences resulted in financial losses (rather than injuries or fatalities) and were associated with interactions between single otter trawlers and oil and gas production-related debris. The odds of an incidence occurring varied according to substrate type and fishing intensity. A risk-model for pipeline–fishing interactions in the Fladen Ground showed that there was significant spatial heterogeneity in the risk of an incident along a pipeline according to the angle and intensity of fishing. The results highlight the need to include the full spectrum of potential losses in fisheries impact assessments associated with the installation and decommissioning of oil and gas assets.
