The first pillar underscores the need for AI systems that are cost-effective, scalable, environmentally sustainable and legally supported, balancing short-term costs with long-term social and ecological benefits. The second stresses adherence to fair, reliable and ethical access to digital resources, recognising that without strong governance data and algorithms risk becoming fragmented or misused. The third pillar addresses the necessity of rigorous validation across entire AI pipelines, including preprocessing, model evaluation and benchmarking against alternative ground truths, to ensure reliability in real-world applications.

I present a structured framework for integrating GenAI across eight interconnected components of the modelling cycle: model scoping, data gathering, conceptual framework development, model development, model execution, validation and calibration, reporting and stakeholder engagement. Through analysis of current applications and emerging research, I demonstrate how GenAI can automate routine tasks, democratise access to sophisticated modelling approaches, and improve model quality. Achieving success will require overcoming persistent challenges, including data limitations, institutional barriers and ethical concerns. I propose a research agenda addressing three streams: capability assessment to systematically evaluate GenAI's potential in marine ecosystem modelling; avenues for ensuring scientific integrity and reliability; and socio-technical integration to address ethical and institutional challenges. While GenAI offers the potential to enhance modelling, a human-centered approach is essential, where GenAI augments, rather than replaces, human expertise in model validation, interpretation of results and ensuring sustainable management outcomes.

Improving energy efficiency is, in addition to shifting to alternative fuels, a crucial path towards decarbonizing fisheries. Theory suggests that healthy stocks, i.e., with higher density, should require less fuel to harvest when fishing effort and catches are correlated. This is a situation generally observed in bottom trawl fisheries. Rebuilding stocks could thus represent an important pathway for decarbonization. By analysing available time series data on fuel use intensity (FUI), fleet size and fish price in 13 European and U.S. bottom trawl fisheries, we find empirical evidence that lower FUI is associated with higher stock abundance. Lower FUI is also observed for catches with lower fish prices and with reductions in fleet size. Results suggest that rebuilding fish stocks by setting and following sustainable harvest limits combined with balancing fishing capacity with resource availability can be one part of a decarbonization strategy. However, economic incentives such as fish price and subsidies are counterproductive. Combined, this suggests that energy use and carbon emissions be considered as key fisheries management objectives. The sparse data availability of fuel use in fisheries also points to the need for standardised collection programs to allow for further research for improved understanding as well as monitoring progress towards societal objectives.</p>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 2","pages":"370-380"},"PeriodicalIF":6.1,"publicationDate":"2026-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70059","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146006266","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}

Understanding the impact of environmental change on fish condition may therefore inform sustainable management of human activities in marine ecosystems. We investigated how changes in Canadian Pacific waters may be influencing the average condition of 35 commercially, culturally, and/or ecologically important demersal fish species. Because the condition of mature male and female, and immature individuals differs in its implications for population dynamics, ecological drivers, and measurement variability, we analysed these three maturity groups separately. We estimated density distributions, calculated Le Cren's relative body condition deviations, modelled spatiotemporal change in these deviations, and generated density-weighted annual indices of body condition. We used Bayesian Dynamic Factor Analysis to identify common trends across species and tested for correlations with environmental variables. For most species, warmer sea surface temperature and lagged North Pacific Gyre Oscillation appeared neutrally or positively correlated with condition. Only the immature condition was also strongly correlated with primary production, but this effect was equally likely to be negative (e.g., Pacific Spiny Dogfish, Lingcod, and Sablefish) as positive (e.g., Quillback Rockfish, Southern Rock Sole, and Spotted Ratfish). Our approach propagates uncertainty from condition estimation through to environmental correlations to provide both ecosystem-level and species-specific inference.

The advantages of phage therapy for aquaculture include the natural abundance and diversity of phages in water, and their self-propagation, host specificity, low environmental impact and diverse administration routes. Although the efficacy of phage therapy in controlling the prevalence of bacterial pathogens across various aquaculture species is well demonstrated, the diversity of phage administration methods, experimental conditions, target strains and host physiologies have prevented a clear consensus being reached regarding the suitability of phage therapy for aquaculture. The application of phage therapy as an antimicrobial strategy induces gentler immune modulation compared to antibiotics and disinfectants, which often induce dysbiosis in host microbiomes by eliminating beneficial or commensal bacteria. However, there are divergent results regarding the influence of phage administration upon host microbiome composition and dynamics, with potentially important health implications that require further research. How phage immunogenicity may influence the host immune response is also unclear. Additional concerns include phage-neutralising antibody production, phage-resistant bacteria and horizontal gene transfer of antimicrobial resistance.

The pilots showed that TACs can be made workable in a data-limited, effort-based regime. This was achieved by decentralising program design, using Special Fishing Permits to define fishery units, embedding quotas within the seasonal moratorium, testing allocation methods, and introducing basic monitoring systems. These arrangements facilitated compliance and institutional learning, although measurable ecological outcomes remain uncertain due to persistent data limitations. Our findings suggest that pilots can serve as transitional vehicles toward science-based and rights-based management, but only if their lessons are institutionalised through law, policy, and practice. We highlight that without clear graduation pathways—anchored in three mutually reinforcing pillars of science-based decision-making, integrated monitoring and compliance systems, and rights- and incentive-based governance—China risks locking in administratively convenient but ecologically limited practices.

The interwoven action of these responses cascades up to entire ecological communities. Here, we analysed changes in fish communities over the last three decades in the Bay of Biscay (BoB). We examined changes in multiple indicators across levels of organisation, from individual species physiology to community composition, to test whether trends were consistent with those expected from ocean warming. At the individual and population levels, we assessed changes in species body size, reproductive investment, spawning phenology and spatial distribution on four pelagic fish. Mean adult body size significantly decreased for anchovy, sardine and Atlantic mackerel, but increased for horse mackerel. Anchovy increased reproductive investment and advanced spawning. Atlantic mackerel and horse mackerel spawned earlier and polewards.
