Summary: This study estimates the economic cost of reducing sea turtle bycatch in the U.S. Western Atlantic Commercial Pelagic Longline Fishery, finding that on average, the cost of reducing the take of one sea turtle is $36,957. Shadow prices show significant temporal variability and vary by the targeting behavior of the fleets, which also affects the technical efficiency of fishing fleets.

Summary: In the Pacific Ocean, the bycatch and discard patterns of Chinese tuna longline fleets were analyzed using observer data. Other bony fishes and sharks were the most common bycatch species, and the bigeye tuna fleet had higher bycatch and discard rates compared to the albacore fleet. Bycatch of marine turtles and mammals mainly occurred in the Tropical Pacific, while seabird bycatch was more common in the Temperate Pacific.

Summary: Research found that using light lures in epipelagic longline fisheries may increase catch rates of target species but also result in catching more non-target species. Among different colors, green attractors showed the highest catch rates of target species but also caught the most non-target species, indicating the need for further understanding of the effects of light lures and lunar illumination on fish behavior.

Summary: The global populations of oceanic pelagic sharks have decreased due to overfishing. Internationally protected shark species are still under threat from bycatch in longline fisheries, and the accuracy of population assessments for management is affected by under-reported catches. The extent of under-reporting, however, is not well understood.

Summary: Comprehensive catch data are crucial but currently under-represented by the Indian Ocean Tuna Commission (IOTC). We reconstructed fisheries catches for large pelagic species in the Indian Ocean from 1950 to 2020, finding that the reconstructed catches were 30% higher than the reported data. Distant-water fishing fleets were historically dominant but have been gradually replaced by fleets flagged to Indian Ocean rim countries.

Summary: Apex and mesopredators, such as elasmobranchs, are important for maintaining ocean health. Quantifying at-vessel mortality (AVM) is necessary for effective bycatch management. A study analyzed a global database of 61 elasmobranch species and found that evolutionary history is a significant predictor of AVM rates. The study suggests that measures to reduce catch and AVM levels should be species-specific.

Summary: The study found that using tori lines significantly reduced the likelihood of albatross attempting to contact or actually contacting baited hooks. While albatross captures were also less likely in sets with tori lines, there were not enough captures to draw strong conclusions. Offal discharge during setting was associated with higher seabird interactions, but further investigation is needed to determine the efficacy of this mitigation measure.

Summary: The incidental catch of sea turtles by pelagic longline fisheries in the Northeast Atlantic is a major concern. A study based on data collected from 2015 to 2020 found that sea turtles, mainly loggerhead and leatherback, interacted with the fishing gear in the region. The study also revealed a clear seasonal pattern in turtle bycatch and emphasized the importance of this information for effective sea turtle conservation.

Summary: This study aimed to verify the effectiveness of using circle hooks in the Azorean longline fishing fleet. The results showed that circle hooks can reduce bycatch of loggerhead sea turtles and injuries caused by deep hooking, but the effects on blue shark and swordfish varied.

Summary: Climate change is expected to impact marine environmental conditions and the behavior of large pelagic fish species in the North Atlantic. Changes in climate-induced environmental factors may lead to increased post-release mortality in bycatch species and pose challenges for fisheries management. Stock assessments need to consider species-specific responses to climate variability for effective management.

Summary: There is a lack of reliable catch information for sharks and rays worldwide, with many populations considered Data Deficient. In Western Australia, shark and ray species face extinction threats and commercial catch statistics underestimate the actual extraction level. By reconstructing catch data, it was found that actual catches were 57% higher than officially reported, highlighting the impact of fishing on these species.

Summary: Juvenile grey-headed albatrosses from South Georgia dispersed to the northeast, overlapping with a bycatch hotspot for grey-headed albatrosses reported by the Japanese pelagic longline fleet in the southeast Atlantic Ocean. The majority of birds caught in this area are likely juveniles from South Georgia, indicating a key factor in the sustained population decline. This study emphasizes the urgent need to understand the 'lost years' of marine megafauna for targeted conservation efforts.

Summary: This study provides an integrated perspective of the Portuguese longline fishery targeting swordfish and blue shark in the Northeast Atlantic, examining fishing dynamics, target species catches, and associated bycatch. The research used data from observed fishing sets collected between 2015 and 2020 and employed cluster analysis and generalized additive mixed models to analyze the data. The findings reveal the spatial and temporal patterns of fishing effort, as well as the relationships between target species catches and environmental and operational characteristics.

Summary: The genus Euthynnus, comprising multiple species of marine pelagic fish, shows deep genetic divergence within E. alletteratus, potentially indicating two cryptic species. Management units should be established for E. alletteratus populations. In contrast, E. affinis and E. lineatus exhibit shallow genetic divergence.

Summary: This study presents the first global-scale analysis of blue shark habitat preferences based on a large dataset of observations and environmental data. The results reveal that the blue shark's habitat requirements vary across different size and sex classes, and are influenced by factors such as productivity and temperature. Understanding the habitat needs of sensitive stages in the blue shark population is essential for effective management and conservation of this species.

Summary: This study used acoustic biotelemetry to evaluate the feasibility of restocking hatchery-reared adult dusky groupers in no-take areas of a Portuguese Marine Protected Area. The results showed that none of the tagged groupers settled in the no-take areas, instead leaving mainly at dusk and night. Some individual groupers exhibited extended movements along the Portuguese coast, which is unusual for this species.

Summary: Tagging studies are important for understanding fish population dynamics. This study compared the recapture rates and shedding performance of different tag types (plastic and stainless-steel dart tags) in blue sharks. The results showed that stainless-steel dart tags had higher recapture rates compared to plastic tags, and the shedding probability of plastic tags increased over time. The study suggests that using stainless-steel dart tags can minimize tag loss and increase the probability of obtaining long-term and large-scale recaptures in future tagging studies on large pelagic sharks.

The study finds short-term and synchronised wider movements associated with environmental factors triggering reproduction in this species. Different behavioral groups of fish may aggregate and spawn simultaneously, contributing to the maintenance of behavioral polymorphisms and the species' evolutionary adaptability.
