    A characteristic of costal-pelagic fishes is their large population size fluctuations, yet the drivers remain elusive. Here, the authors analyze a 45-year timeseries of nitrogen stable isotopes measured in larvae of Northern Anchovy and find that high energy transfer efficiency from the base of the food web up to young larvae confers high survival and recruitment to the adult population.

    Using high-resolution stable isotope and microstructure analyses of otoliths, this study reveals that sardine populations in the western and eastern North Pacific have different early life metabolic and growth rates that respond contrastingly to temperature variations. These findings could explain observations of different responses in these populations to decadal-scale temperature anomalies.

    The Covid-19 pandemic has disrupted ecosystem and biodiversity monitoring programs, including marine fisheries surveys. Here the authors combine multiple modelling approaches and data to overcome lost observational effort off the coasts of California in a diversified integrated ecosystem approach.

    Trends in antimicrobial resistance (AMR) in aquatic food animals are seldom documented, particularly in Asia. Here, Schar et al. review 749 point prevalence surveys, describing AMR trends in Asian aquaculture and fisheries over two decades, and identifying resistance hotspots as well as regions that would benefit most from future surveillance efforts.

    Global landings of wild-caught seafood have plateaued in recent years. Analysing trends in global fisheries catches, Watson et al.find that distance between sourcing and consumption has increased steadily since the 1950s, with ocean productivity unlikely to meet current consumption rates by 2100.

    The effects of fishing policies that adjust selectivity are unclear. Here, Svedäng and Hornborg show that fishing practices that increase selectivity of the Eastern Baltic cod have negatively affected its productivity, suggesting that fishing policies should prioritize catch rates over yield.

    Discards from fishing vessels are food for scavenging species, so ending the practice may have ecological consequences. Here, Heath et al. show that improving selectivity so that unwanted fish are not caught, achieves conservation benefits, while simply requiring that vessels land their entire catch, does not.

    Potential fishery benefits of Marine Protected Areas are widely acknowledged, yet their impact on fishery dynamics remains poorly understood. Here the authors provide evidence that Marine Protected Areas can rapidly increase catch rates in adjacent areas, without measurable disadvantages for fishers.

    Catch certificates and eco-labels are used to control illegal fishing worldwide, however, independent control methods are needed. Here, gene-associated SNPs are used to assign individual marine fish back to their population of origin with high precision, with potential application for illegal fishing control.
