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: A study investigated microplastic ingestion by vertically migrating and nonmigrating mesopelagic crustaceans and fishes in the Gulf of Mexico. The results showed that 29% of crustaceans and 26% of fishes had ingested microplastics, with an average plastic length of 0.59 mm. Nonmigratory crustaceans had significantly higher levels of microplastic ingestion than migratory crustaceans, and the frequency of microplastic ingestion by nonmigratory fishes increased with depth.

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: 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: 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: Sharks, including blue sharks, exhibit exaggerated physiological responses to capture and handling stress. The study found that blue sharks in recreational fishing can withstand capture and handling in a catch-and-release setting without experiencing blood acidosis. However, smaller individuals may be more susceptible to capture stress. The findings have implications for angler education in the recreational fishery.

Summary: Total dissolved gas (TDG) supersaturation, caused by sources such as hydroelectric dams, can lead to gas bubble trauma (GBT) in aquatic animals. Locomotion is hypothesized to promote bubble nucleation in fish tissues exposed to TDG supersaturation. This study aimed to understand the effects of locomotion on GBT in rainbow trout exposed to TDG supersaturation in static or flowing water conditions. The results indicate that there is no statistically significant difference in GBT occurrence between static and flowing water conditions.

Summary: The spatial ecology of common carp within Lake Ontario was studied using passive acoustic telemetry across multiple spatial scales. The study found that season and physical habitat conditions significantly affected the habitat preference of common carp, with higher preference for sites with increased submerged aquatic vegetation during spring and summer. Larger individuals were more likely to be absent from the array during summer. Non-resident common carp exhibited extensive movements along the nearshore of Lake Ontario during spring and summer and were detected throughout the entire basin.

Summary: The authors synthesized evidence to address methodological concerns and misconceptions surrounding the interpretation of critical thermal maximum (CTmax) in ecological and evolutionary studies of fishes. They highlighted the importance of considering factors that influence thermal limits when interpreting CTmax in ecological contexts. Applications of CTmax include mitigating the effects of climate change, informing infrastructure planning, and modeling species responses to temperature change. Future research directions aim to improve the application and interpretation of CTmax data in ecological contexts.

Summary: Despite major threats to humanity, evidence-based decision-making in environment management is relatively nascent. However, there is a growing number of environmental evidence syntheses available for decision-makers. Research is urgently needed to understand patterns and trends in environmental evidence use, and there is a need for reflection and sharing among those involved in producing and using evidence syntheses. It is hoped that these ideas will lead to further scholarship to enhance evidence-based decision-making and benefit the environment and humanity.

Summary: Freshwater habitats are facing biodiversity loss at a rate two to three times higher than terrestrial and marine habitats. In order to reverse this trend, we propose four actions to increase the recognition, value, and protection of freshwater biodiversity: reshaping our relationship with freshwater habitats, appreciating indigenous knowledge, linking science and action more directly, and elevating the importance of freshwater habitats in conservation planning (RACE). Both freshwater scientists and the wider conservation community have key roles to play in implementing these actions and ultimately winning the RACE.

Summary: Shore-based shark fishing in Florida attracts a wide variety of anglers, and concerns about proper handling methods of caught fish arise due to the threat of extinction for many shark species. This study examined the information channels used by anglers to obtain knowledge about fishing skills and best practices for catch-and-release. The findings suggest that interpersonal communications and the internet are the main sources of information for anglers, and support for fisheries management is associated with pro-environmental behavior.
