Federal actions include Executive Order 14276, <i>Restoring American Seafood Competitiveness</i>, 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.</p>","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}

We synthesize available information on the understudied Great Lakes pink salmon invasion and highlight how this case can inform research and management related to expansions and invasions of this species in the Pacific, Arctic and North Atlantic Oceans. 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? (2) How do temperature extremes influence their ecology? (3) What causes departures from the 2-year life cycle? (4) How important is it for the phenology of life history events to match new habitats?

We previously showed how the <i>r</i>_max of rays and skates (subclass Batoidea) scales with adult body size, temperature (and hence depth) such that smaller-bodied species and those in warmer, shallower waters have greater <i>r</i>_max and, therefore, will be less sensitive to overexploitation.

Offspring size mediates relationships between <i>r</i>_max, adult body size, temperature and depth. Despite inhabiting warmer, shallower waters, tropical rays generally have larger offspring and lower <i>r</i>_max compared to temperate skates. Our result explains why tropical rays are less resilient to overfishing despite expectations from metabolic theory that tropical species should have faster life histories and therefore higher <i>r</i>_max and greater resilience than temperate species. Although the drivers of large offspring size in tropical rays remain uncertain, we use basic models of temperature- and size-dependent predation to hypothesise that this is due to greater predation risk in shallow tropical waters selecting for increased maternal investment in offspring size via evolution in viviparity and matrotrophy.

However, the sustainability of these species is difficult to assess as the lack of information limits the use of traditional stock assessment methods. We demonstrate, using a complex multi-species fisheries exemplar, the efficient assessment of large numbers of diverse species, using a modified Sustainability Assessment for Fishing Effects (SAFE) approach. Applying this technique to 256 teleost and elasmobranch species caught in Australia's Northern Territory Demersal and Timor Reef Fisheries, we first applied an initial screening assessment to identify at-risk species followed by a secondary SAFE assessment for a more detailed evaluation. To enhance the precision of the secondary assessment, we incorporated species distribution modelling and refined fishing footprint estimates through spatial analysis of trawl paths, from vessel monitoring system data. Additionally, we integrated Monte Carlo simulations into the SAFE process to quantify uncertainties in fishing footprint and capture efficiency parameters. The conservative criteria applied in the initial screening process assessed 208 species as low-risk, with the remaining 48 species evaluated through our modified secondary SAFE approach. These 48 species were also subsequently classified as low-risk. Our approach adds steps to the SAFE process but enables us to efficiently assess large numbers of diverse species and thereby allows resources to be allocated to those species most at-risk. This adaptable approach is readily modifiable for application in other fisheries, including those with no or limited effort and catch data.</p>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 4","pages":"831-849"},"PeriodicalIF":6.1,"publicationDate":"2026-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70085","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751748","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, what if these relationships are shadows of other life-history processes? To explore this question, we simulated populations where the environment affects natural mortality, a life-history process often assumed to be constant, to determine whether spurious environment-recruitment relationships arise. Specifically, we produced a series of simulations in which the environment affects only one life-history process, while estimation models were misspecified with respect to which process was environmentally driven. Our simulations show that misspecified models consistently produce false detections of environmental effects on recruitment when the environment affects only natural mortality. These results indicate that previously identified environment-recruitment relationships that later broke down may have been artifacts of environmental effects acting on other life-history processes that were assumed to be constant. Focusing exclusively on recruitment may therefore obscure the true pathways through which environmental variability influences population dynamics. Ultimately, sound scientific advice in the face of marine ecosystem complexity requires hypothesis driven model comparisons and transparent model assumptions.</p>\u0000 </div>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 4","pages":"865-875"},"PeriodicalIF":6.1,"publicationDate":"2026-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695718","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 long-standing ‘recruitment problem’ has become even more urgent under ongoing climate change and the associated regime shifts overturning traditional predictive models. Leveraging the highly data-rich Northeast Arctic cod (<i>Gadus morhua</i>, Gadidae), this study proceeds beyond traditional data and method limitations. Such an initiative appears most timely because its recruitment (<i>R</i>), measured as number of 3-year-olds, is currently low and raising socio-economic concerns. We hypothesize a causal map and then apply Dynamic Structural Equation Model with sensitivity analyses to explore complex response patterns. The higher temperature exhibited a dual role: positive for spawning stock biomass (SSB) but negative for abundance of 1-year-olds (Age1) and <i>R</i>. Predation on postlarvae by northward-migrating Northeast Atlantic mackerel (<i>Scomber scombrus</i>, Scombridae), but not by herring (<i>Clupea harengus</i>, Clupeidae), appeared to influence Age1 negatively. As expected, fishing reduced SSB, whereas prey availability, represented by mesozooplankton biomass and stomach fullness, exerted a positive effect on Age1 and <i>R</i>. These suite of links remained robust, but shorter time series (&lt; 30 years) may blur underlying patterns. Essentially, the low recruitment success (<i>R</i>/SSB) seen since 2010 (from the 2007 year class onwards) seems related to an overall poor situation for the 1-year-olds.

Through this meta-analysis, we investigated how elevated mercury (Hg) and polychlorinated biphenyls (PCBs)—two prevalent and problematic contaminants—in large, and presumably old fish, affect toxicant concentrations in their eggs and subsequent offspring success. We synthesized published data to analyse: (1) the association between maternal size and egg toxicant loads, (2) the relationship between maternal muscle toxicant concentrations and egg toxicant loads and (3) the impact of egg toxicant loads on offspring hatching success, mortality and growth. Our results revealed that maternal size was strongly, positively associated with egg toxicant concentrations, with Hg showing an effect size nearly double that of PCBs. Similarly, toxicant concentrations in maternal muscle tissues were strongly, positively associated with egg concentrations for both contaminants. Additionally, elevated egg toxicant loads were associated with decreased hatching success and increased offspring mortality, whereas impacts on growth rates varied by toxicant, highlighting negative impacts on early life stages. These findings have important implications for fisheries management, particularly regarding the protection of ‘big old fat fecund female fish’ (BOFFFFs). Although BOFFFFs typically produce numerous eggs, our study shows these benefits may be offset by increased toxicant transfer to offspring in contaminated systems. Management strategies should consider the reproductive benefits of BOFFFFs and the potential disadvantages of maternal toxicant transfer when establishing conservation priorities, especially in historically or currently contaminated systems or populations more susceptible to bioaccumulation.</p>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"27 4","pages":"895-911"},"PeriodicalIF":6.1,"publicationDate":"2026-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.70089","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148208926","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}
