Summary: Understanding and managing fishery selectivity is crucial for fisheries management. China's domestic fisheries have been perceived as unselective, but the evidence is lacking. This study found that primary target species were absent in many Chinese fisheries, and low-value and juvenile mixed catch were common. Key commercial taxa were subject to multi-gear and multispecies fisheries, but selective gears were used infrequently. Management actions are needed to control fishing pressure on primary target species and by-product species.

Summary: This study employed two types of questionnaires to validate the fishing gear and seasonality of fishing activities in the multi-gear coastal fleet in the Algarve, and additional fishing metiers were identified. The results obtained from the questionnaires contribute to a clearer understanding of the gear used and the distinction between target species and commercial by-catch.

Summary: Monitoring fishing activities is crucial for marine conservation. The advance of Automatic Identification System (AIS) provides the opportunity to enforce monitoring and promote responsible fisheries. A study in China found that fishing efforts were concentrated along the coastal line and highly influenced by the summer moratorium. Most fishing activities occurred in a limited spatial and temporal scope. Additionally, there has been a shift of fishing efforts from the Eastern China Sea to the coastal areas of south China in response to an extension of the summer moratorium.

Summary: The environmental effects of static gear fishing can lead to permanent changes in habitat and benthic community structure. Ecosystems exposed to prolonged pressure from static gear may undergo permanent changes. A systematic review can provide clarification on the short and long-term impacts of commercial static gear fishing on benthic community diversity.

Summary: In this study, the evolution of fishing effort and capacity in Egypt's marine fisheries over the past two decades was analyzed, and some conclusions were drawn. The results showed an overcapacity of engine power in the Mediterranean fleet and an excess number of vessels in the Red Sea. Despite considerable technological advancement, the catch per unit effort for both fleets is now lower than it was at the beginning of this century. The limitations, gaps, and future directions for addressing the issue of overcapacity and managing these fisheries are provided in the last section.

Summary: Our study examined fish assemblages in 22 reservoirs of the Tennessee River basin using electrofishing and gillnetting methods. While the two gear types represented different aspects of fish assemblages, they were both correlated with the spatial location of the reservoirs.

Summary: Based on industry interviews, this study examines the economic impacts of using Biodegradable Fishing Gear (BFG) as a measure to mitigate the ghost fishing impact caused by lost fishing gear. The findings suggest that the use of BFG is primarily a technical challenge rather than an economic problem. The costs for fishermen using BFG are mainly related to reduced fishing efficiency rather than investment and maintenance costs. The implementation costs for BFG in the Channel static gear fishery could be as high as 8 million pounds, but if the fishing efficiency issue is resolved, the costs could be significantly reduced or even result in a small positive benefit.

Summary: Illegal, unreported, and unregulated (IUU) fishing, facilitated by vessel identity obfuscation, leads to significant financial losses annually. Through the combination of vessel identities and GPS data, we conducted a global assessment on fishing compliance, reflagging patterns, and foreign-owned vessel fishing. Approximately 17% of high seas fishing activities involve potentially unauthorized or unregulated vessels, with concentrated hot spots in the western Indian and southwest Atlantic Oceans. Reflagging, primarily done in a few ports by fleets with high foreign ownership, is a common tactic to evade oversight. Fishing by foreign-owned vessels is concentrated in specific areas of high seas and national waters, often using flags of convenience. These findings provide insights into the extent of potential IUU fishing globally and empower authorities to enhance oversight.

Summary: The objective of this article is to investigate the optimal allocation of fishing effort in the Norwegian bottom-trawl fleet within economically important species. The results show that the spawning migration of Northeast Arctic cod and the effort allocation behavior of coastal fleet have significant impact on maximizing expected return. Additionally, fishing activities targeting cod in the Arctic region contribute the most to annual fishing revenue, while saithe fishery conducted in the southwest of the Norwegian coast has the lowest economic contribution.

Summary: The study aims to describe the current awareness of International Maritime Organization (IMO) biofouling guidelines among fishermen and managers in the northern Persian Gulf, in order to improve biofouling management on all types of fishing vessels. The majority of industrial fishermen and all managers were found to be aware of the IMO biofouling guidelines, but traditional fishermen had a lower level of awareness and faced various challenges.

Summary: This study investigates the footprint and illegal fishing behavior of the Sri Lankan fishing fleet, highlighting the influence of social, environmental, and policy factors on fisher decisions. The findings emphasize the importance of adopting a social-ecological lens in understanding human behavior and non-compliance with rules, advocating for a nuanced approach to fleet monitoring and management.

Summary: Managers of recreational fisheries often make assumptions about fishing effort without considering angler behavioral adaptations. This study found that fishing effort on charter boats was consistent and primarily influenced by the availability of target species, while party boat anglers were more responsive to possession limits.

Summary: This study used modified pontoon traps to reduce the impact of seals on cod fisheries in the southern Baltic Sea. The design of the pontoon traps was tested for its effects on catch rates, and it was found that using a leader net with a 100 mm center-knot to center-knot mesh-size on a bottom-set fish chamber yielded the highest catch rates. No seal-induced damage to cod was observed in the pontoon traps.

Summary: This study reports the results of clearing derelict gillnets from the Salish Sea from 2002 to 2021. A total of 5638 nets were removed, covering an area of 11.6 km2. The Reporting, Response, and Retrieval (RRR) Program implemented in 2012 has successfully reduced re-accumulation and long-term impacts on species and habitats.

Summary: Understanding fishing effort allocation is crucial for spatial management planning in fisheries, particularly in small-scale fisheries with multi-specific contexts. Random Walk models prove to be useful for modeling small-scale fleets operating in southeast Mexico, with the Composite Correlated Model identified as the most suitable model for this fleet. Further studies should consider increasing the number of fishing trips and conducting specific studies by gear and fishing method, along with applying relative and absolute fit tests to compare the performance of RW models.

Summary: Research on the sex-specific population dynamics of bottlenose dolphins off the Alvarado Lagoon System in the southwestern Gulf of Mexico revealed that resident females are usually more abundant than males. The population parameters were influenced by high site fidelity, restricted ranging patterns, and low sporadic recruitment from the superpopulation.
