Abstract Climate change is projected to affect the productivity of global fisheries. Management based on maximum sustainable yield (MSY) has been effective at eliminating overfishing in many regions. However, continuing use yield‐maximizing targets under climate‐driven changes can result higher anthropogenic pressure populations subject climate‐related stress than maintaining status quo management targets. We demonstrate this effect using a theoretical example and case studies from snow crab eastern Bering Sea marine fisheries database. In these examples, conservation gain (i.e. biomass ocean) larger small harvest made through climate adaptation MSY‐based management. The aggregate increases as harmful impacts worsen. Instead climate‐adaptive targets, new tools are needed balance food production ecosystems displaying non‐stationary productivity.

Although biodiversity loss adversely influences a variety of ecosystem functions, how declining wild food diversity affects nutrient supplies for people is poorly understood. Here, we analyze the impact on nutrients supplied by fish using detailed information from Peruvian Amazon, where inland fisheries provide critical source nutrition many region's 800,000 people. We found that impacts depended compensation, trophic dynamics, and functional diversity. When small sedentary species compensated declines in large migratory species, fatty acid increased, while zinc iron decreased. In contrast, probability failing to maintain or supply risk increased when were nutritionally unique. Our results show trait-based regulations public health polices need consider biodiversity's vital role sustaining nutritional benefits over 2 billion dependent foods across globe.

Abstract Understanding and managing fishery selectivity to target species desirable size are instrumental fisheries management. China, as the world's largest producer of marine capture fisheries, has been widely perceived possess unselective domestic fisheries. To date, this perception remains largely anecdotal conjectural, hindering development evidence‐based effective management solutions. Here, we conducted a literature review examine magnitude scale in China. By collating analysing 140 fishery‐level 807 species‐level records from 66 peer‐reviewed publications 2010 2021, found that primary were absent 59% while unidentifiable low‐value juvenile mixed catch universal. Key commercial taxa subject nationwide multi‐gear multispecies each involving an average 3.33 types gear accounting for less than 25% individually. The ‘permissible gears’ defined by national regulatory catalogue selective over caught negligible by‐products, though they used frequently, representing only 24% records. While fishing can provide seafood supplies China's large population potentially facilitate balanced harvest, actions needed control pressure on by‐product species. Amid ongoing reform proposed recommendations tailored needs social contexts, including trade‐off between socio‐economic ecological goals, contemplating impacts when implementing TAC programmes, strengthening monitoring inform at multiple scales.
