Summary: The endemic Maugean skate in western Tasmania, Australia, faces uncertainties in its main habitats due to anthropogenic impacts. Key life-history parameters such as reproductive information and growth were studied to inform conservation actions. Conservation strategies should focus on reducing human impacts on the environment, particularly river flows and nutrient load associated with hydroelectricity production and salmonid aquaculture to secure the future well-being of this species.

Summary: The COVID-19 restrictions caused a global pause in human activities, providing an opportunity to assess human impact on animal behavior and space use. Variations in restrictions across Australian states have different impacts on human interactions with the marine environment. Through acoustic tracking data analysis and long-term monitoring, researchers can assess how global events like COVID-19 can affect animal movement and distributions.

Summary: Fish migration and movements play a crucial role in determining population structure, and the detection of acoustically tagged fish can be used to assess stock structure and connectivity. Network analysis helps identify population connections between species and supports existing stock discrimination. Species with less variability in movements require smaller sample sizes to reveal useful stock structure information.

Summary: The ocean is often seen as a sink for pollution in the Anthropocene era, with various types of pollution threatening marine ecosystems. Despite awareness and data on risks, there is a significant delay in implementing strategies to address marine pollution. Experts present two future scenarios and prioritize actions for governments, industry, and consumers to reduce pollution and move towards a more sustainable future.

Summary: Southern Bluefin Tuna is managed internationally by CCSBT, with a national assessment of the recreational fishery conducted across five state jurisdictions in Australia. The recreational sector has been allocated 5% of the CCSBT quota, marking the first official recognition of recreational fishing in an Australian Commonwealth managed fishery.

Summary: Shifts in marine species distributions associated with climate change occur across large spatial areas and long time periods. Marine recreational fishing occurs in most countries with many participants interacting regularly with the environment, yet there have been few studies on the views of recreational fishers towards climate change. This study provides a baseline to assist in informing policy changes that might be required to address the impacts of climate change.

Summary: Recreational fishing is a popular leisure activity, but it causes significant fish mortality in many areas. However, the sector's objectives and the data needed to track its performance are poorly understood, which limits its inclusion in fishery harvest strategies. In this study, we reviewed the available recreational fishing data sources in New South Wales, Australia, and evaluated their usefulness for monitoring the performance indicators specific to recreational fishing within harvest strategies. We found that most social objectives of recreational fishing are outside the scope of traditional harvest strategies, but ecological objectives are linked to underlying performance.

Summary: Field metabolic rate (FMR) is a comprehensive measure of metabolism that provides insight into the ecology and resilience of a species. FMR can be used to assess the role of animals as consumers, and this study used FMR to model the metabolism of Greenland sharks in two coastal inlets of Baffin Island. The results showed that Greenland sharks have low FMR and energy requirements, indicating that they require very little energy to sustain themselves in their natural habitat.

Summary: Marine ecosystems and their biodiversity are essential for sustaining life on Earth and human well-being. However, these ecosystems are being rapidly degraded due to unsustainable use and climate change. The challenge is to protect marine ecosystem biodiversity and function while providing vital resources. Immediate action is needed to avoid tipping points and decline, while long-term planning and commitment are necessary for a sustainable future beyond 2030.

Summary: Predatory fishes play a key role in tropical fisheries, but their diet and trophic structure are poorly understood. Using stable isotopes and dietary prey items, this study revealed differences in diet and trophic structure among five predatory fish species. The results showed that delta N-15 values increased with fish body size, indicating a relationship between trophic position and body size.

Summary: This study evaluated the impact of seismic survey signals on early life history stages of Southern Rock Lobsters. The results showed that exposure to air gun signals could impair righting ability and increase intermoult duration in lobsters. However, there was no mortality observed and juvenile lobsters exposed at a distance showed recovery.

Summary: Marine organisms generally swim at higher speeds during strenuous activities such as predation or escape. A study found that ram ventilating sharks and Atlantic bluefin tunas exhibited an increase in swimming speed after being stimulated, which gradually returned to their cruising speeds. The elevated swimming behavior may be a mechanism to remove accumulated lactate.

Summary: Marine recreational fishing in Norway faces challenges in estimating catches due to its long coastline and large tourist fishery. This study conducted surveys to monitor recreational anglers, estimate their catches, and evaluate the fishery in Troms and Hordaland County. The results showed differences in catches between the two regions and revealed that recreational anglers in Hordaland harvest more cod in coastal waters than commercial fishers. This study provides valuable information for developing monitoring methods and supporting science-based fisheries management.

Summary: Recreational fishing is undervalued and poorly integrated into the management of multi-sector fisheries, leading to marginalization of recreational fishers and hindering fisheries sustainability. A study on marine fisheries harvest strategies in 11 nations reveals a gap in inclusion of recreational fishing compared to the commercial sector. The lack of explicit objectives, data collection, performance indicators, and management controls in harvest strategies for recreational fishing reduces its effectiveness in achieving sustainability goals.
