Summary: Management strategy evaluation (MSE) is a cutting-edge approach for testing and comparing management strategies, accounting for various uncertainties. Small pelagic fish play a vital ecological role in marine food webs, but present challenges to MSE and other evaluation methods due to their substantial ecological and life history uncertainties.

Summary: Marine ecosystems are facing significant changes due to the establishment and spread of Non-Indigenous Species (NIS). The challenge lies in how to limit the risks and exploit the benefits provided by these organisms sustainably. A new approach called Ecosystem-Based Fishery Management for NIS (EBFM-NIS) is proposed to manage NIS and achieve sustainable exploitation by balancing costs and benefits.

Summary: Dynamic closures are more effective at reducing bycatch for mobile species in dynamic environments, while static closures are suitable for geographically associated species. A 20% observer coverage is sufficient to create useful closures, with a moderate level of effectiveness in reducing bycatch.

Summary: We developed a social-ecological model of the Kenai River Fishery through collaborative interviews with stakeholders using a participatory Fuzzy Cognitive Mapping process. Individual models were combined into an aggregated model that represents the system's structure and function. The model helps illustrate the interconnectedness of the fishery's social-ecological system, facilitates management discussions, and explores components that affect sustainability.

Summary: This paper examines the impact of government subsidies on the development of carbon-sink fishery through a three-party evolutionary game model. The results show that government subsidies can incentivize the development of carbon-sink fishery from both the production and consumption sides, but the amount of subsidies has a negative impact on the stability of the game system.

Summary: Management strategy evaluation (MSE) is an important tool for fisheries management, and stakeholder participation, especially from fishers, is crucial for its success. This study proposes an intermediate approach using information from semi-structured interviews to conduct a desk-based MSE when direct fisher involvement is not possible.

Summary: Proper measurement of technology knowledge and social change is crucial for managers to advance strategies in technology management, and structural equation modeling is the ideal method to assess the measurement quality of decision variables and understand their relationships. A tailored-fit model evaluation strategy is proposed to utilize the strengths of fit indicators, with a recommendation to use only a few indicators in model evaluation to avoid errors.

Summary: Ecosystem dynamics at the northwest Antarctic Peninsula are influenced by interactions between physical and biological processes. Commercial harvesting is impacting baleen whale populations, while climate change is altering the ecosystem composition. The increasing commercial harvesting of Antarctic krill has the potential to lead to competition between krill predators and the fishery, but understanding the abundance and distribution of krill predators is limited.

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: Building resilience in coastal resources and communities requires a holistic research approach that integrates socioecological system components and captures dynamic interactions between them. This study applies ecosystem oceanography to marine conservation and management goals, using a conceptual ecosystem-oceanography model and survey methods to understand ecosystem structure and function. By linking empirical processes with biophysical models, it aims to evaluate management goals and explore future scenarios. This approach is applied to identify key drivers for recent surprises in the California Current Ecosystem and proposes it as a means of anticipating future states and increasing preparedness.

Summary: A simulation was conducted to project the changes in fishery landings of the northern subpopulation of Pacific sardine, showing a northward shift in landings with declines at southern ports and increases or stability at northern ports. However, total sardine landings were found to be uncertain. The study also identified key constraints on future landings that can be targeted for further assessment.

Summary: Research shows that the onset, intensity, and duration of marine heatwaves are often predictable, with skillful forecasts possible from 1 to 12 months in advance depending on region, season, and climate mode status. Setting decision thresholds based on the probability of MHW occurrence can promote climate resilience in global marine ecosystems.

Summary: Multispecies models have been around in fisheries since the 1970s, but their operational use in fishery management is limited. This is surprising given the inherent multispecies nature of species and fleet interactions and the push for ecosystem-based fisheries management. We provide recommendations to address the impediments to the regular operational use of multispecies models.

Summary: Subseasonal to decadal ocean forecasting plays a crucial role in managing living marine resources in a changing ocean. This study demonstrates the importance of incorporating three-dimensional biogeochemical information into ecological forecasts to anticipate fluctuations in bigeye tuna populations in the Pacific Ocean. The findings highlight the impact of ocean warming and deoxygenation on the dynamics of bigeye tuna and emphasize the need for efficient dynamic management strategies to promote sustainable use of marine resources.

Summary: Recent improvements have been made in reducing bycatch in many fisheries, but it remains a threat for numerous species globally. This study evaluated the effectiveness of temporal, static, and dynamic area closures on reducing bycatch and maintaining target catch in 15 fisheries around the world. The results showed that dynamic closures could achieve an average reduction of 57% in bycatch without sacrificing target catch, compared to only 16% reduction achieved by static closures. The use of dynamic management is more effective in reducing bycatch and will be increasingly valuable in the face of climate change.
