However, fragmented regional survey data often hinder such efforts for transboundary populations. A prime example is Pacific Spiny Dogfish (<i>Squalus suckleyi</i>, Squalidae), a small shark with a remarkably slow life history and wide-ranging distribution. Dogfish are now caught incidentally but were heavily fished along the Pacific US–Canada coast ≈80 years ago. Reports on local population trends have conflicted along the coast, suggesting that movement between regions may be responsible. We fit spatiotemporal models integrating data from 10 surveys to synthesise trends in biomass, abundance, distribution and thermal niche for dogfish across their entire eastern Pacific Ocean range. Prior to 2003, Alaskan biomass increased through the 1990s whereas California to British Columbia indices were variable and imprecise. However, during 2003–2023, we found a coastwide 51% (95% CI: 38%–61%) decline in dogfish biomass with mature females and immature dogfish showing the largest proportional declines. Regionally, declines were steepest for the US West Coast (71%–85%) and Canada (58%–82%), while Alaska showed less severe declines (13%–54%). Off the US West Coast, dogfish shifted into deeper waters as temperatures in their habitat increased, but these patterns do not explain the coastwide declines. Our results suggest population declines are primarily driven by reduced abundance rather than between-region movement, indicating elevated coastwide conservation concern and helping focus investigations of causal mechanisms.</p>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 1","pages":"1-12"},"PeriodicalIF":6.1,"publicationDate":"2025-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145545470","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}

We compiled a comprehensive dataset from multiple sources: global occurrence records from the Global Biodiversity Information Facility between 1980 and June 2024, and long-term fish fauna monitoring data collected from 1992 to 2015 across four reservoirs in the upper Paraná Basin. Global occurrences were aggregated into country-level distribution polygons to estimate species richness per nation, while records from the United States were analysed within freshwater ecoregion boundaries to highlight regions of high invasion risk. In the upper Paraná case, AFF presence was determined using a presence-absence matrix, and temporal trends in richness and proportion were analysed using linear and non-linear models. Our results, based on 76,796 records of 281 AFF species, reveal a marked increase in AFF occurrences outside the Amazon Basin, particularly in South America and the United States. In the upper Paraná River Basin, AFF richness increased until approximately 2005, while the proportion continued to rise throughout the study period.

Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes. In this review, we synthesise current knowledge on how rising ocean temperatures may affect elasmobranch fertility across key stages of the reproductive cycle, including gametogenesis, mate searching, sperm storage, fertilisation, embryonic development, and offspring production. Evidence from 88 species suggests that thermal stress could impair sperm and oocyte quality, disrupt reproductive timing, alter embryonic growth and survival, and potentially exacerbate sexual conflict. While some reproductive strategies such as embryonic diapause, sperm storage, or behavioural thermoregulation may provide short-term buffering capacity, their effectiveness under rapid and sustained warming remains uncertain. We further highlight the macroevolutionary significance of elasmobranch reproductive diversity, as well as the conservation implications of fertility constraints under global change. Addressing these knowledge gaps is essential to refining demographic models, improving extinction risk assessments, and guiding the design of climate-resilient management strategies, including fisheries regulations and marine protected areas. By explicitly linking reproductive biology with conservation policy, we argue that understanding thermal fertility limits is key to predicting elasmobranch population trajectories in a warming ocean.</p>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 1","pages":"41-55"},"PeriodicalIF":6.1,"publicationDate":"2025-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145382214","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}

There is instead a widespread need for shifting ecological baselines to more effectively guide decisions into the future. What has not been as widely recognised is that the relevant timescales differ substantially across ocean-related decisions, from lead times of hours to decades depending on the decision being made, and that this range necessitates a matching range of ecological forecast products across similar timescales. At the moment, a predictability gap exists at intermediate timescales, from multi-annual to multi-decadal forecasts. Because most fisheries and many other ocean activities rely on biological conditions like fish abundance or distribution, the ecological inertia of organismal growth, generational turnover, movement, and food web dynamics can help push ecological forecasts further across this gap. To realise this potential for more effective and usable ecological forecasts, coordinated research and implementation at the intersection of biology, climate science, social science, and decision-making is needed. These efforts will be critical for forecasting shifting ecosystem baselines and sustaining fisheries, ocean ecosystems, and the ocean economy in the coming decades of rapid change.</p>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 1","pages":"13-23"},"PeriodicalIF":6.1,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145306201","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}

However, this potential has not yet been fully exploited. We conducted a meta-analysis on 44 datasets from 34 distinct marine and freshwater species and different types of data (acoustic detections, depth, acceleration and positioning). Our aim was to explore the potential of acoustic telemetry in identifying chronotypes as consistent among-individual differences in circadian-related behaviours. First, we applied hidden semi-Markov models to classify individual time series into active and rest states. Subsequently, we computed two classical circadian-related behavioural traits: awakening time (as the activity onset) and rest onset (as the activity offset). Subsequently, we identified distinct phenotypes by decomposing behavioural variation into within- and among-individual components based on repeatability scores. We found evidence of distinct chronotypes in 17 species, with average repeatability scores of 0.52 for awakening time and 0.43 for rest onset, revealing that chronotypes are common in aquatic species. Our findings highlight that both the data type, particularly acceleration sensors, and the number of detections are effective tools for exploring chronotypes. Our study proposes a novel approach to characterising daily activity patterns in aquatic species, predominantly in fishes, and provides guidelines for investigating chronotypes across diverse taxa.

Here, we offer a synthetic perspective on the downscaled application of the safe operating space concept to inform the stewardship of watersheds in this time of rapid climate change, with particular focus on watersheds that support coldwater migratory fishes such as Pacific salmon. First, we review the safe operating space concept as it applies to salmon watersheds as social-ecological systems. Salmon watersheds, and the benefits they provide for diverse peoples, are under enormous cumulative pressure from climate change as well as local activities such as forestry, urbanisation, mining and agriculture. We identify four general syndromes of dual local and climate pressures. For example, local pressures, such as the removal of riparian vegetation that shades streams, can exacerbate climate warming of water temperatures. Furthermore, extractive industries can damage or destroy future habitats and thus erode adaptive capacity. As an illustrative example of how the safe operating space concept can be operationalised, we assess alternative plausible watershed futures of land use and climate change scenarios and salmon performance. Collectively, this work showcases tangible options for local management to help give salmon watersheds the time and space to cope with climate change.

Indigenous people from the Pacific Coast of Canada to Baja California fished for tuna for &gt; 5000 years, but tuna were generally not one of the most abundant species targeted by Indigenous fisheries, which largely focused on nearshore kelp forest, rocky reef and estuary habitats. The scale of Indigenous tuna fisheries is relatively small when compared to capitalist commercial fisheries, which commenced by the onset of the 20th century, rapidly accelerated during World War I and II, and declined by the mid-1980s or earlier. Although Indigenous people fished for tuna in the northeastern Pacific for millennia, significant human use of and influence on offshore ecosystems in the northeastern Pacific is primarily associated with the mid-20th century Great Acceleration and associated global ecological impacts.

Home to the largest SSF population in the Americas, Brazil ranks among the top countries globally in fisherwomen—with nearly 900,000 women engaged in the sector, representing half of its SSF workforce. Despite their numbers and contributions to sustainable practices, such as low bycatch rates and minimal fuel usage, fisherwomen consistently earn less than men and are largely overlooked in social protection policies. Our analysis reveals a historical and persistent underrepresentation in policy, fishery-dependent research, and social science, culminating in legal and economic imbalances—particularly in regions where fisherwomen form the majority, such as the North and Northeast. This results in reduced access to fisheries-derived income and management benefits compared to fishermen. Moreover, fisherwomen remain underrepresented in decision-making processes, despite their work aligning with key Sustainable Development Goals, including poverty reduction, gender equality, and sustainable resource management. This study offers recommendations beyond policy, including capacity-building initiatives and implementation of gender-disaggregated data systems to advance equity and social justice for Brazilian fisherwomen, providing a potential model for nations facing similar socio-environmental challenges.
