Summary: By analyzing field survey data, catches, and underwater video from 2020 to 2022, as well as historical research, we found that the fish species composition and community structure in Yongle Atoll have changed over the past 50 years. The proportion of large carnivorous fish has significantly decreased, while the proportion of small and medium-sized fish has increased. The fish species in Yongle Atoll have closer relatives and higher species uniformity, indicating an unstable state possibly caused by multiple impacts such as overfishing, fishing methods, environmental changes, and habitat degradation. Continuous monitoring and conservation efforts are needed to protect and restore the coral reef ecosystem and fishery resources of Yongle Atoll.

Summary: Research shows that the catch of the curimatA (P. nigricans) in the Amazon Basin is influenced by the variability in river water levels, with a negative relationship between water levels and catches. Additionally, there is a positive correlation with a 15-month lag between river water levels and catch, indicating that years with more extensive flooding lead to greater catches 15 months later.

Summary: Inland fisheries make significant contributions to food security and livelihoods globally, but their conservation and management are often overlooked. The Rome Declaration outlined ten key steps for responsible inland fisheries management, which can benefit from lessons learned from local/regional actions to inform a more global action plan. Success in the responsible management of inland fisheries will require coordinated efforts among on-the-ground practitioners, scientists, stakeholders, rightsholders, and international decision makers.

Summary: Our research explored how different fishing gears select for distinct functional traits of fish assemblages within different habitat types. Gears used in reef habitats showed high selectivity for sedentary and benthic species that form small schools, while gears used in coastal lagoons selected highly mobile, pelagic species that form large schools. There was low competitive interaction between gear types, with direct associations between gears and fish functional traits, highlighting the need for further research to understand global patterns of trait selectivity by gear type.

Summary: The Amazon floodplains, which represent valuable ecosystems, are neglected and not included in protected areas. Climate change and its consequences on floodplains are not considered in species distribution models and protection gap analyses. This study shows that a significant portion of the suitable environment for the Arapaima fish is currently unprotected and will decline with future climate change. Protection gaps are found mainly in the south-western part of the basin, and the extension of the current protected area network is recommended.

Summary: The term data-limited fisheries refers to situations where there is insufficient data to support a fully integrated stock assessment model. These conditions can range from a complete lack of data to reliable quantitative assessments, and can also be constrained by limited resources. The DLMapper tool is introduced to identify the level of data limitation in a fishery and provide guiding principles for management. By outlining the conditions that create data-limited situations and linking them to guidance, this approach aims to improve the communication and development of limited stock assessment in fisheries management.

Summary: Analysis of small-scale inland fisheries (SSIFs) often lacks a comprehensive understanding of their contributions to society due to insufficient attention and the diverse nature of these fisheries, which are often located in remote areas. By involving fishers as monitors, this study provides valuable fishery-dependent estimates of yields, biological attributes, and spatiotemporal dynamics of lakes in the Sao Francisco basin. The results demonstrate the importance of participatory monitoring in generating knowledge, overcoming knowledge gaps, and enabling effective management of small-scale fisheries at both local and regional levels. Given the lack of a national monitoring program in Brazil, participatory monitoring offers a cost-effective solution for obtaining credible data on small-scale fisheries.

Summary: This article proposes an approach to assess data-less small-scale fisheries (SSF) using local knowledge to produce data, life history theory to describe historical dynamics, and length-based reference points to evaluate stock status. The approach was applied in three data-less SSFs in the Congo Basin, and the results showed declines in fish catch and species diversity, indicating overfishing. The approach is cost-effective and can inform management and restoration efforts in SSF.
