However, meta-regression analyses showed that latitude explained variation in trophic guild richness within reservoir stretches, whereas reservoir area was the only significant predictor in downstream stretches. Although significant residual heterogeneity remained, these results indicate that trophic responses to river impoundment are strongly context dependent and influenced by environmental conditions operating at different spatial scales.

Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist. Most studies focussed on a limited set of species from North America and Europe, leaving broad uncertainty across phylogenetic groups, geographic regions and multi-stressor conditions. In adult fish, especially females, elevated pCO2 can shift energy allocation to prioritise reproductive output at the expense of egg or clutch size. While adult and juvenile fish have well-developed acid–base balancing systems, embryos and larvae possess only rudimentary mechanisms, making them more vulnerable to OA. This article stresses the importance of understanding these physiological and mechanistic responses to predict the future of fish stocks and ecosystem health as OA intensifies due to ongoing CO2 emissions. Our results highlight that OA responses in fish are highly variable and often specific to life stage and species, with acute and sometimes stage-specific effects not fully documented. Lastly, our recommendations on targeted research and funding are necessary to address the remaining knowledge gaps, including broadening taxonomic and geographic sampling, exploring multi-stressor scenarios and improving understanding of the downstream effects of OA on fish reproduction and development. Maintaining robust fish populations is vital for food security, employment and ecosystem functioning, making continued investigation into OA's impacts a scientific and societal priority.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 5","pages":"1176-1192"},"PeriodicalIF":6.3,"publicationDate":"2026-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70106","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148322779","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}

Anisakid nematodes currently represent the most significant fish-borne parasitic threat in Atlantic wild fisheries. Recent regional surveys and global syntheses suggest significant increases in the prevalence and intensity of anisakid infections across multiple commercially important fish species, raising concerns for public health, marketability and consumer confidence. At the same time, the growing popularity of raw and lightly processed seafood has increased human exposure to anisakids, potentially amplifying infection risk independently of ecological changes in parasite abundance. Here, we synthesise current knowledge on anisakid parasitism in Atlantic fish and critically examine the interacting mechanisms that may be driving these trends. We highlight the roles of climate-driven ecosystem change, recovery and redistribution of marine mammal definitive hosts, shifts in fish host ecology, evolving fishing and post-capture handling practices, changing seafood consumption patterns, and major advances in parasite detection and diagnostics. While improved surveillance has undoubtedly increased reporting, converging evidence suggests that changes in host–parasite dynamics are also occurring. We further discuss practical mitigation options across the seafood value chain, from onboard handling and processing to retail, food service and consumer awareness, emphasising the need for coordinated, risk-based approaches. Collectively, these developments challenge the long-standing perception of wild fish, especially when consumed raw or lightly processed, as inherently safe, underscoring the importance of integrating ecological insight, consumer behaviour, technological innovation and public-health guidance to ensure sustainable fisheries and safe seafood consumption.\u0000 </div>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 5","pages":"1224-1233"},"PeriodicalIF":6.3,"publicationDate":"2026-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148582175","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 many, public opinion seems mysterious—rarely aligned with scientific evidence, yet not random, as it is shaped by frames, narratives and social factors. Here, we examine public acceptance of governing a new fishery through a survey experiment conducted in 10 countries. As a case, we consider the mesopelagic zone, a largely untapped resource with high biomass and economic potential. However, mesopelagic fishing also entails ecological and social risks, including impacts on food webs, carbon sequestration and global equity. Acceptance varied substantially across countries. Support was lower in wealthier countries, such as Germany and the Netherlands, where respondents also favoured stricter regulation, and higher in Indonesia, Nigeria, the Philippines, and, to a lesser extent, Spain, where support for regulation was weaker. Different frames have different effects across countries. For example, emphasizing risks to food webs reduced acceptance in Argentina and Nigeria, while highlighting disproportionate burdens on the Global South further lowered support only in Nigeria. At the individual level, confidence in government and large companies increased support for mesopelagic fishing, whereas other demographic factors played smaller roles. These findings emphasize the role of equity concerns and localized public opinion in shaping policy for fisheries and highlight the context-dependent power of narrative framing.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 5","pages":"1074-1087"},"PeriodicalIF":6.3,"publicationDate":"2026-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70100","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148288484","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}

By combining artificial intelligence (AI) methods with remotely-sensed data, researchers can now detect, classify and analyse fishing behaviour across vast and previously unobservable ocean regions. Technological advancements in vessel tracking are rapidly reshaping fisheries science and management, enabling new insights into fleet behaviour and its effects on marine ecosystems. This review synthesizes the state of the science in AI-enabled vessel tracking and highlights its transformative potential across four core domains: stock assessment and catch reconstruction, effort controls, spatial management, and monitoring, control, and surveillance. We explore how satellite-based vessel-tracking data complement legacy systems such as logbooks and observers, while also unlocking new capabilities to track ‘dark vessels’ that are not publicly observable by other means. We also identify key scientific and institutional challenges that are priorities for advancing the scientific frontier, including: filling data gaps for small-scale fleets, resolving uncertainty in behavioural inference and vessel identities for dark fleets, integrating catch and effort reporting, expanding real-time decision support, designing cutting-edge policy instruments to manage fisheries and developing shared standards for algorithm transparency and validation. As the field matures, we propose a forward-looking agenda to ensure that fleet tracking delivers on its promise to enhance transparency, support real-time decision-making and drive more inclusive, science-based ocean governance.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 5","pages":"1134-1150"},"PeriodicalIF":6.3,"publicationDate":"2026-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148582183","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}

Exploring relationships between environmental drivers and time-varying recruitment rate will provide insight into recruitment processes, and suggest how fisheries managers may adapt biological reference points and adjust harvest-control rules in response to changes in the ecosystem state. To test for significant effects on the recruitment rate of 48 commercial United States fish stocks with nonstationary per-capita recruitment, environmental indices from two Atlantic and three Pacific regions are incorporated into a state-space dynamic Ricker stock-recruitment model. We developed two model variants for incorporating climate into the state-space model, one based on the climate variable itself and the other on its rate of change. Simulation tests indicated that if the true system has a climate driver, most of the time a climate-enhanced model will detect it. However, the different model variants may have similar statistical support, such that model selection may be unable to distinguish the ecological hypotheses of the climate-recruitment interaction. For 35 (73%) of the true stock time series, at least one environmental variable was identified as nominally significant for improving on the non-climate dynamic model. The simulation results indicate that the identified environmental indices likely do impact recruitment of the given stocks, even if the form of that effect may not be clearly identified. Our results can now support more detailed stock-specific analyses of fisheries dynamics, climate drivers, model specification and ultimately management action in the future.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 5","pages":"1193-1209"},"PeriodicalIF":6.3,"publicationDate":"2026-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70109","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148401110","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}

Federal actions include Executive Order 14276, Restoring American Seafood Competitiveness, which directs agencies to address unfair trade practices, unsafe imports and to develop a coordinated seafood trade strategy. Additional measures include a tariff package imposing a 10% duty on nearly all seafood imports and 30% on seafood from China, as well as new anti-dumping and countervailing duty orders on warm-water shrimp. This paper presents Gulf shrimp as a clear example of ‘shrimp survival nationalism’, which reflects nationalism from a position of weakness in a global commodity chain. Similar combinations of tariffs, labelling and safety rules are evident in the cases of catfish, crawfish, Alaska seafood and tuna. Drawing on research in gastronationalism and resource nationalism, this paper argues that these policies reframe seafood as a national asset to be protected rather than as a generic traded commodity. For fisheries science, this means that prices, trade rules and food safety standards can no longer be considered external market conditions. Including seafood nationalism in modelling and governance analysis reveals how politically driven changes in tariffs, import bans, labelling laws and safety enforcement alter incentives, redistribute benefits and harms, and complicate cooperation across fisheries and countries.","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 4","pages":"1047-1055"},"PeriodicalIF":6.1,"publicationDate":"2026-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70096","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148209061","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}

Accidentally introduced to Lake Superior in 1956, pink salmon quickly spread to all five Great Lakes, displaying unexpected behaviours and life history plasticity. This invasion history demonstrates a remarkable ability of pink salmon to establish from a small founder population, colonize large areas, produce explosive year classes to rapidly increase in abundance, and complete a full life cycle entirely in freshwater. One of the most striking changes is a shift from their rigid 2-year Pacific life cycle to a variable maturation age ranging from 1 to 4 years, likely influenced by prey availability as well as temperature and other environmental factors. We discuss implications for expansions elsewhere and outline five research themes necessary for understanding pink salmon dynamics in the Great Lakes with broader relevance for managing the species everywhere: (1) What drives rapid changes in abundance?
