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: 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.

Summary: In this study, an extensive survey was conducted to document and quantify recreational fishing patterns across the Israeli Mediterranean shoreline. The results showed that recreational fishing accounted for 10%-37% of the total annual fishing yields, similar to other regions of the Mediterranean. Non-indigenous species were found to be common in recreational catch and contributed significantly to local fishery yields. The study identified 23 species that are targeted by both recreational and commercial fishing, indicating potential conflicts between these fishing sectors.

Summary: Some marine mammals have modified their behavior to take advantage of the opportunities provided by fishing, leading to interactions that involve removing or damaging marketable organisms and bait. The use of the term "depredation" when referring to this behavior could reinforce misunderstandings and the belief that marine resources belong solely to humans. Alternative wording would prevent ambiguity and acknowledge the ecological roles of large marine predators.

Summary: The study found that Permit mainly reside in artificial reefs in the Caribbean Sea region, with their residency peaking in the spring and summer months. The high residency of Permit at important spawning sites indicates vulnerability to fishing pressure and inadequate current regulations. Additionally, seagrass flats in close proximity to spawning locations are important food sources for Permit during the extensive spawning season.

Summary: Animals need to move between different habitats to complete their life cycle, but anthropogenic activities and infrastructure have a negative impact on animal movement, especially in aquatic habitats. Understanding fish movement is crucial for understanding how human activities affect the spatial ecology of fish, which can inform management strategies. Various methods, such as observation, tracking, and DNA analysis, can be used to study fish movement, and combining these methods can improve management efforts. It is important for different jurisdictions to collaborate in managing fish that move across boundaries. Interdisciplinary data analysis can provide a holistic understanding of fish movement and help in selecting cost-effective and evidence-based management actions that balance the needs of fish and human activities.

Summary: This study investigated the degradation of different absorbable suture materials under biologically relevant conditions for temperate freshwater fish. The results showed that naturally derived collagen-based sutures experienced major decreases in tensile strength within 2 weeks of submersion but maintained high knot security throughout the study period, while synthetic sutures showed little to no degradation after 8 weeks. The findings have important implications for fish welfare considerations such as suture retention, wound healing, inflammation, and infection under natural conditions.

Summary: Ecosystem-based management is costly, but its effectiveness compared to traditional species-focused alternatives in conservation is uncertain. This study conducted large-scale experiments in fish conservation, finding that adding coarse woody habitats did not enhance fish abundance, while creating shallow water habitat consistently improved the abundance of juvenile fish. Species-focused fish stocking as an alternative approach completely failed. The findings question the efficacy of species-focused conservation actions in aquatic ecosystems, and recommend ecosystem-based habitat management.

Summary: Understanding the attitudes of recreational anglers is crucial for fisheries management. In this study, we examined the relationship between angler characteristics (specialization, catch orientation, place attachment, and demographics) and attitudes towards conservation and management of northern pike in Germany. Our results showed that angler specialization, catch orientations, place attachment, and demographics were consistent predictors of attitudes towards management and conservation. Addressing conflicts in the pike fishery can be achieved by targeting specialized and release-oriented anglers who have higher conflict sensitivity and are more willing to accept regulations.

Summary: The use of plastic structures in freshwater ecosystems to enhance fish habitat or restore freshwater systems has become popular, but there are concerns about ecological benefits and potential pollution from plastic degradation. The evidence base for using plastic materials in these activities is limited, and there is a need to consider the full life cycle of restoration and potential environmental consequences. Natural materials should be embraced for habitat restoration, and stakeholders should have a say in material choices. Based on current evidence, the use of plastic for habitat enhancement or restoration in freshwater systems is littering.

Summary: This paper examines the relationship between involvement in recreational fishing and decision rules, specifically regret-minimizing versus utility-maximizing behavior. The study finds that individuals who are more involved in fishing are more likely to exhibit regret-minimizing behavior. Factors such as behavioral commitment and psychological involvement are significantly related to the decision rule, while skills, attitudes, and place attachment do not impact the decision rules followed. The study also demonstrates that welfare estimates of policy changes are influenced by the decision rule, and assuming regret-minimizing behavior results in lower estimates compared to assuming utility maximization behavior.
