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.</p>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 3","pages":"627-642"},"PeriodicalIF":6.1,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70073","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":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While significant research has been dedicated to understanding how organisms may respond to future climate change, most of these studies focus on individual levels of biological organisation in controlled laboratory settings, which often fail to capture the complexity of natural ecosystems. Organisms respond to climate stressors across various levels of biological organisation, which also involve complex interactions or feedback mechanisms among levels, making it difficult to generalise responses to climate change from laboratory experiments or single levels alone. Natural analogues provide a unique opportunity to observe complex ecological interactions in real-world environments with long-term exposure to climate change stressors. Here, we provide a systematic literature review to reveal how natural analogues of ocean warming and ocean acidification can be used to assess fish responses to climate change across multiple levels of biological organisation (from molecular to biogeographical scales) and to assess how cross-level buffering and feedback mechanisms may shape fish species persistence in a future ocean. We identify key knowledge gaps and propose research frameworks that integrate natural analogues with laboratory experiments, mesocosms, and predictive models to better capture the complexity of fish responses to climate stressors in a more holistic way. Finally, we highlight the importance of coordinated, cross-system research using multiple natural analogues to reveal adaptive mechanisms and strengthen predictions of fish community reorganisation under climate change.</p>\u0000 </div>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 3","pages":"417-430"},"PeriodicalIF":6.1,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146122171","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}

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.

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.</p>\u0000 </div>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 3","pages":"571-590"},"PeriodicalIF":6.1,"publicationDate":"2026-04-12","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}

Here, we analyse a unique database of 73 quantitative ICES stock assessments to provide estimates of <i>B</i>_MSY across the Northeast Atlantic and apply a Bayesian state-space model to estimate joint trajectories of <i>F</i>/<i>F</i>_MSY and <i>B</i>/<i>B</i>_MSY.

However, using MSY <i>B</i>_trigger as a surrogate for <i>B</i>_MSY results in an over-optimistic classification of stock status, which conflicts with past levels of exploitation and may hinder stock rebuilding and the achievement of MSY objectives. Future projections from individual assessment forecasts predict further increases in <i>B</i>/<i>B</i>_MSY under current <i>F</i> levels.

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 km². The methods developed allow quantification of three vessel operations activities improving purse seiners effort metrics compared to classical binary (fishing/non-fishing) approaches.

Overwhelmingly, despite moderate institutional support, developers work beyond regular hours, especially when upscaling a tool to wider use, providing updates to the tool, and conducting maintenance activities. Notably, our expectation that tools with limited employer/institutional support do not survive was only partially supported—we found many tools persist despite limited support, primarily through substantial voluntary effort from developers.

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.
