Agentic AI can automate computing workflows and will increasingly be used in ecological modelling. However, the quality of AI generated results is of concern because of risks of logically flawed code and inconsistent answers. Here, we tested whether a general‐purpose AI agent (Roo Code) can write computer code and interpret results to complete three common ecological and fisheries modelling workflows: (1) fitting a von Bertalanffy growth curve to data, (2) writing code and interpreting results of a generalised linear model relating fish abundance to habitat and (3) completing a yield per recruit analysis. We used replicate prompts and a structured evaluation rubric to ask if the agents' results were accurate and if responses were consistent. The agent successfully completed all three tasks in some replicates; however, accuracy varied widely across replicates. Of the large language models we tested, Claude Sonnet 4.5 had the greatest accuracy and always produced accurate responses for the simplest modelling task, but was less consistently accurate for complex tasks. All models sometimes overlooked user instructions for which methods to use. Our findings show that agents can sometimes complete ecological and fisheries modelling, but that they are not yet consistent and accurate enough to rely on for management advice. We outline prompt designs and workflows that improve reliability and discuss the importance of ensuring human oversight for credibility of modelling that is used in management.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"60 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147489995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding their interactive effects is crucial for managing harvested populations. Here, we first review current knowledge of harvest and warming interactions, focusing on experimental applications that provide unique insights into short‐ and long‐term effects difficult to study in wild populations. We then present findings from a multi‐generational experiment exposing 18 zebrafish populations to combined harvest and warming selection. Treatments included three types of size‐selective fishing (~80% mortality) and two temperatures (26°C ‘control’ and 30°C ‘warmed’). Warmed populations exhibited expected temperature‐size‐rule responses: juveniles grew 18% faster and matured earlier, while adults were 3%–5% shorter and ~10% lighter. Gaussian selectivity (removing medium‐sized fish) led to adults that were 5% longer and 18% heavier, while sigmoidal selectivity (removing large fish) resulted in 4% shorter and 15% lighter adults. Fishing and warming had increasingly interactive impacts on body sizes across generations. At the end of the treatment generations, warming combined with sigmoidal selectivity produced the smallest fish (6% shorter, 20% lighter), while Gaussian selectivity compensated for warming‐induced size declines. Juvenile body size changes were mostly reversible but warming and fishing induced an evolved change in adult body size. Warming caused a 15% reduction in maximum yield‐per‐recruit, while Gaussian selectivity increased maximum yield by 20%, and sigmoidal selectivity reduced it by 11%. Our work demonstrates both synergistic and antagonistic impacts of fishing and warming on fish sizes and yields, and suggests that warming effects can be partially mitigated by fishing practices that protect large individuals.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"11 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147465421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the NW Mediterranean, the distribution of small pelagic fish (SPF) stocks is currently assessed through annual acoustic surveys. Although accurate, these surveys might lack the temporal resolution needed to capture population dynamics. Analysing fishing fleet spatial behaviour allows estimation of fishery impacts and can uncover patterns of target species at high temporal resolution. In this study we apply machine learning models to classify multiple vessel operations on vessel monitoring system (VMS) data for purse seiners targeting SPF populations. Three main vessel operations were defined based on onboard observations: Fishing, Tracking and Cruising. Then, random forest models were trained to predict vessel operations in VMS data using seven predictive variables. Machine learning models highly improved predictions accuracy (81% and 73%) compared to a classical speed filter method (60%). Fishing effort metrics were computed and compared across predictive methods resulting in a high overestimation of fishing activities when using a speed filter approach. The effect of spatial resolution in fishing effort metrics was also tested revealing a good performance of random forest predictions at 2–3 km 2 . The methods developed allow quantification of three vessel operations activities improving purse seiners effort metrics compared to classical binary (fishing/non‐fishing) approaches. Consequently, spatially explicit catch per unit effort (CPUE) estimates for SPF will also be improved as well as the accuracy of the information needed for spatially manage of this fishery.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"5 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147447658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, uncertainty specifications (i.e., factors and levels included in uncertainty analyses) for tuna assessments vary within and among tuna Regional Fisheries Management Organisations (tRFMOs). We reviewed the uncertainty specification in 133 stock assessments conducted over the past 20 years by five tRFMOs, covering seven major commercial tuna species. Our analysis revealed four key findings: although a wide range of uncertainty specifications has been applied, only a few factors are commonly considered across assessments; patterns in uncertainty specification are more closely aligned with management organisation than with species; the emphasis on different factors has shifted over time (e.g., increasing attention to growth and decreasing focus on data weighting); and a change to the modelling platform is a key factor leading to changing uncertainty specifications between successive assessments. Our findings demonstrated the diverse range of uncertainty specifications in tuna stock assessments, and revealed the important role of subjective factors in making these selections. We propose some best practices for specifying uncertainty to enhance consistency and reducing subjectivity across tuna stock assessments.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"10 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147447660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prior research has identified adaptive traits that, when present in a management system, can promote effective responses to these changes and minimise negative outcomes for fish and fishery systems. Understanding the extent to which managers identify these traits as important and actively influencing management can identify gaps and opportunities for putting this theory into practice. To address this, we surveyed 321 fishery management professionals and scientists across all eight U.S. fisheries management regions. Questions focused on 16 adaptive traits related to topics such as systemic flexibility, opportunities for knowledge exchange and agency to act. For each trait, at least 68% of respondents identified the trait as important for supporting adaptation in their region. The two traits relating to fishermen and management's ability to learn and innovate were the most widely identified as important for adaptation. However, when asked about the role of management in influencing these traits, positive perceptions dropped by about 20% (at most 44% agreement per trait). Perceived importance and influence of adaptive traits significantly varied by the education level of survey respondents, with higher education levels correlating with higher perceived trait importance. Mapping this mismatch between perceived importance of adaptive traits and the ability of management to address them provides a blueprint for areas where a shared understanding of climate‐ready fishery goals would benefit both fishermen and regulators under future change.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"93 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147447704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, we developed an Artificial Intelligence (AI) pipeline that turns angler‐reported photos into standardised records of catch composition and individual body lengths. The workflow consists of four steps: (i) automatic fish detection, (ii) pixel‐accurate segmentation, (iii) species classification trained with few labelled images and (iv) length estimation calibrated with a measurement board carrying fiducial markers (machine‐readable reference tags). We validated the system on smartphone images from a mixed‐species fishery in the western Mediterranean under realistic conditions (variable lighting, occlusions, mixed catches). The detection–segmentation stage achieved F1≈0.93. The classifier reached 85% accuracy across 38 species using only 12 training images per species, showing strong data efficiency. Length estimates were robust, with centimetre‐level error suitable for size‐class analyses. Leveraging large, pre‐trained foundation models, only a lightweight adapter requires training, keeping data and compute demands low and enabling rapid extension across regions, gear types and species lists. When integrated with existing catch‐reporting smartphone applications and agency workflows, the pipeline delivers instant angler feedback and streams standardised, analysis‐ready records to managers. In practice, this unlocks operational monitoring: near‐real‐time indicators of catch composition and length structure, automated size‐limit compliance checks and cost‐efficient inputs to stock assessment and adaptive management.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"31 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147380739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock. More specifically, since 2006 the average recruitment at age 3 per unit spawning stock biomass has dropped to a very low level. Here we review recent literature and data to evaluate potential causes of poor recruitment. We find that in most years the large spawning stock was successful in producing offspring up to the 0‐group stage, but the survival thereafter was reduced—leading to few recruits into the fishable stock. Evidence points to consequences of northwards shifts of spawning locations, reduced inflow of Calanus and density dependent factors influencing pre‐recruit survival at times when the spawning stock was at a record high level. However, large uncertainties in the causes of recruitment failure remain at a time when the Barents Sea ecosystem is experiencing unprecedented warming. A precautionary measure to avoid further decline and potential stock collapse in the current situation is to lower fishing pressure and improve management by setting reference points based on the recent period with low productivity. Including demographic characteristics like age diversity as explicit management targets to ensure spatial and temporal spread in spawning should be a goal for future method development.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"6 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147380740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically reviews a decade (2012–2021) of peer‐reviewed literature to investigate several aspects of hatcheries and stocking programmes in salmonid conservation and fisheries enhancement in the Pacific and Atlantic basins. Our interdisciplinary research team reviewed both natural and social science literature across three literature databases. A total of 459 natural science and 88 social science articles were included following two rounds of screening. Those articles were evaluated for several interdisciplinary questions including geographic and species focus, key messages and management recommendations, and presence of Indigenous and local knowledge and climate change considerations. Results reveal disciplinary and geographic trends in how hatcheries were discussed, with a persistent lack of definitional clarity around hatchery types and goals. Notably rare in the literature were studies that included Indigenous Knowledge systems or local ecological knowledge. Very few studies meaningfully integrated climate change as an analytical lens despite its increasing relevance to salmonid conservation and human–salmon relationships. We argue for clearer reporting, greater integration of climate considerations to the field, and stronger inclusion of diverse knowledge systems and priorities, particularly Indigenous‐centred, to advance a more effective dialogue on hatcheries for fisheries enhancement and conservation.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"409 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146222838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Marine fisheries are a critical source of protein and essential micronutrients for billions of people worldwide, supporting both local diets and global food security. International trade shapes modern blue food systems, influencing broader distributions and availability of these ‘blue nutrients’. Yet, the structure of these trade networks, the nutritional composition of exported fisheries, and the implications for local food security remain poorly understood. Using global marine fisheries trade data from 1996 to 2020 combined with species‐level nutrient compositions, we analysed production, consumption and nutrient balances for 12 PICs and used network analysis to characterise the structure of international blue nutrient flows. Here we show that many PICs experience persistent net losses of essential nutrients, particularly vitamin B12, protein and fatty acids. This results in nutrient yields far below population needs, with only a few PICs (Vanuatu and Kiribati) meeting average requirements. Compared to global fisheries trade networks, regional PICs trade is more fragmented and less mutually connected, relying on a small number of intermediary countries (Papua New Guinea and Fiji). Despite high domestic production and consumption, 54% of blue nutrients are exported from PICs rather than retained locally, leaving local nutritional deficits unaddressed even as PICs supply global seafood markets. Combining trade, nutrient and network analyses can help inform strategies to increase nutrient retention, strengthen food security and support resilience for PICs in the modern blue food economy.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"1 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146205032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review synthesises recent advancements in CVAs, focusing on methodologies, geographic applications, stakeholder participation and their contributions to fisheries management. While many CVAs emphasise ecological or social dimensions, recent efforts have integrated these components, offering holistic insights into the vulnerabilities of fisheries as coupled socio‐ecological systems. Key innovations include participatory approaches that incorporate expert knowledge and stakeholder input alongside advances in quantitative modelling and spatially explicit analyses. Our review highlights specific examples where CVAs have informed various management applications, such as species protection under the U.S. Endangered Species Act and the design of adaptive harvest strategies in Australia. However, barriers remain, including inconsistent methodological standards, limited uptake in nations with low‐income economies and challenges translating CVA outputs into actionable policies. Looking ahead, developing generalised, integrated frameworks that bridge ecological and social dimensions, identifying ways to link CVA outputs to management guidance, and improving methodologies for data‐limited contexts will all improve uptake and application of CVAs. Strengthening the connections between existing CVAs and climate‐ready fisheries through adaptive management strategies can support fisheries management outcomes in a changing climate while balancing ecological sustainability and socio‐economic equity.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"13 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146205301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
