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: Small-scale fisheries play an important role in the economic and cultural aspects of coastal areas worldwide. However, these fisheries often have high rates of unintentional catching of protected marine species. Recent studies have suggested that net illumination could be an effective method to reduce sea turtle bycatch in these fisheries. A controlled experiment conducted in a coastal gillnet fishery in Indonesia showed that net illumination significantly reduced sea turtle bycatch, particularly for green sea turtles, without affecting the overall catch and target species. Additionally, the study found that the market value of the catch increased when net illumination was used. These results suggest that net illumination could be a viable conservation tool for small-scale gillnet fisheries in Indonesia and Southeast Asia.

Summary: The bycatch of the endangered Australian sea lion in gillnet fisheries off South Australia has been a major threat to its populations. A comprehensive assessment combined with management measures, including spatial closures, observer programs, and incentives for alternate fishing methods, resulted in a significant reduction in sea lion bycatch mortality and a transition to longline fishing. The successful implementation of these measures showcases how effective management can mitigate bycatch mortality of marine mammals.

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 found significant under-reporting of cetacean bycatch in fisher logbooks, with observers reporting much higher numbers in trawls, nets, and hook and line gears. Despite legal requirements, fishers lack incentives to report and have concerns over negative repercussions to the industry. Introduction of electronic monitoring may provide a more viable option for obtaining reliable bycatch estimates and could potentially replace logbook reporting.

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 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 assessment of bycatch data quality and estimation methods in U.S. commercial fisheries between 2005 and 2015 showed improvements in sampling design leading to higher tier classifications for most fisheries. Regional trends in improvement were identified, with Alaska fisheries showing the most progress. The enhancements in bycatch data quality and estimation methods were attributed to financial investments in observer programs and effective conservation measures by NOAA Fisheries and regional fishery management councils.

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: 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: Sharks typically have long lifespans, slow growth rates, and low fecundity, making them vulnerable to fishing. Developing management reference points for elasmobranchs based on their life-history information is more feasible than traditional stock assessments. Evaluating natural mortality rate estimators is crucial for developing reference points, with different methods producing varying results for estimating fishing mortality reference points.
