Summary: Blue shark species have been declining due to overfishing, and their stock status was evaluated using a new assessment model (CMSY++) in the South Atlantic. The results indicate that the blue shark stock may be witnessing overfishing and is being overfished. The use of different catch time series and priors had varying effects on the output results of the model.

Summary: The Socotra Archipelago in Yemen heavily relies on small-scale fishing, but the reporting of fisheries catches has been incomplete. This study reconstructs the total catches and fishing effort in the region from 1950 to 2019, finding that the officially reported catch accounts for only 20% of the total reconstructed catch. The findings suggest overexploitation of resources and highlight the importance of sustainable management for the fish stocks in the Socotra Archipelago.

Summary: Some marine mammals have modified their behavior to take advantage of the opportunities provided by fishing, leading to interactions that involve removing or damaging marketable organisms and bait. The use of the term "depredation" when referring to this behavior could reinforce misunderstandings and the belief that marine resources belong solely to humans. Alternative wording would prevent ambiguity and acknowledge the ecological roles of large marine predators.

Summary: The bivalve wedge clam Donax trunculus in Spain has seen a decline in wild stocks in the Mediterranean region. The hand-operated dredge fishery is still important, but lacks scientific information for sustainable management. This study aims to characterize the fishery, assess its impact on megabenthic fauna, and analyze its effects on the wedge clam.

Summary: This article discusses the challenges and difficulties in eliminating harmful fisheries subsidies, pointing out some key issues currently facing negotiations, such as the lack of clear metrics for measuring the scale of subsidies. Researchers use different subsidy metrics and find that different global regions and countries may be considered as "top" subsidisers, highlighting the potential issue of solely using the absolute amount of subsidies as an indicator of harm.

Summary: Changes to fishing gear configurations have the potential to decrease injury and mortality for non-target species in commercial fisheries. This two-part study found that switching from wire to monofilament leaders can reduce shark catch rates while maintaining catch rates of target species, and that monofilament leaders are more durable than wire leaders after soaking.

Summary: The study examines information processing in the adoption of Total Allowable Catches (TACs) under the EU's Common Fisheries Policy, finding that over time TACs have become more closely aligned with incoming signals about fish stocks, influenced by changing discourses around fisheries conservation and institutional adjustments in EU fisheries policy.

Summary: Avoiding unwanted catches and reducing discards is an important objective of fisheries management. Fishers can improve selectivity of their fishing operations through technical measures, gear modifications, and adjusting when and where to fish. Real-time information sharing within a fleet can help fishers avoid unwanted catches, but there is often reluctance to share catch information with others.

Summary: Spearfishing is a popular activity in tropical and subtropical coast of Brazil, with a high selectivity towards large trophy species. Experienced spearfishers tend to catch larger fish, with herbivores and macro-carnivorous fishes being the most important trophic groups contributing to catch composition biomass.

Summary: We model the temporal participation behavior of harvesters in a fishery with individual quotas for both target and bycatch species. Our study finds the existence of dynamic bycatch avoidance, where harvesters use quota allocations to reduce harvesting during periods of high bycatch. Our policy simulation shows that opening the season earlier can reduce bycatch while maintaining the main target catch.

Summary: This study investigated the trends in fishing effort and catch per unit effort of small-scale marine fisheries in the Mozambique Channel region in East Africa from 1950 to 2016. The study found that with an increase in fishing effort, there was a 91% decline in overall catch per unit effort, indicating a potential risk of overexploitation in small-scale fisheries.

Summary: Catch efficacy and bycatch are important factors in fishing gear sustainability. Gillnets are the most popular gear due to their efficiency, but they have issues with bycatch and low-quality catch. Handlines have advantages in terms of low capital investment, high-quality fish, low bycatch, and low carbon footprint. LED handline attachments were found to increase the catch rate of Atlantic cod in previous research, but our study found no significant effect. The use of green LEDs, however, was found to decrease the bycatch of Atlantic wolffish.

Summary: The aim of this study was to determine the importance of technical characteristics of different vessel components for the landings of various fishing fleets in Portugal. Using Generalized Linear Models, it was found that the different fishing fleets have varying importance to landings, and technical characteristics do not have the same influence on these components.

Summary: Small-scale fisheries are crucial for coastal areas' food security and livelihoods, but gillnet fisheries often result in high levels of bycatch, causing significant environmental and economic issues. However, there is a lack of widely adopted solutions to reduce bycatch, especially in developing nations.

Summary: The use of deep convolutional networks and statistical models in automatically estimating the number and mean length of fish caught in fisheries shows promise in improving the accuracy and efficiency of stock assessment and management, allowing for high-resolution monitoring of fishery dynamics.
