Summary: The functional diversity of commercial marine fish communities significantly responds to climate change and fishing pressure. Climate warming has a positive effect on functional evenness but a negative effect on functional divergence. In contrast, increasing fishing pressure has the opposite effects. These findings are driven by the varying relative contributions of fish species or species groups to the functional space.

Summary: This study examines the temporal variability in ecological sensitivity and vulnerability of Portuguese fisheries landings. Contrary to global trends, the sensitivity of the landings did not decline between 1989 and 2015. Trawling fleets showed increased sensitivity, while multi-gear fleets compensated for high vulnerability through species diversification, and purse-seine fleets had a high fishery dependence on few species.

Summary: One of the current challenges in conservation is balancing economic goals dependent on ocean resource extraction with marine biodiversity conservation. Using NCSM as a case study, it was found that allowing commercial fishing reduces species protections and poses risks to marine species in surface and midwater regions. This demonstrates that a fisheries management policy is insufficient to protect unique ecological resources like those found in the NCSM.

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: Weather is a crucial factor affecting occupational health and safety in the fishing sector, but it is rarely considered from a governance perspective. This study investigates the weather/fishing safety governance ecosystem in Atlantic Canada, examining existing policies and the challenges they face. The findings highlight that current governance efforts primarily focus on risk communication and training, although weather is just one of many factors influencing fisher decisions. Other critical safety factors are shaped by different agencies and policies that do not traditionally consider weather or safety. Therefore, integrating meteorological and health and safety perspectives into fisheries management could help mitigate the impact of weather on fishers' decisions.

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: 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 past decade has witnessed a growing international concern for the conservation status of sharks and rays, which are heavily traded due to the demand for their valuable commodities. Many countries have recognized the urgency to regulate this trade and have voted to include more shark and ray species in the CITES appendices. However, the identification of shark fins before they enter international trade poses a major obstacle for CITES compliance. This study evaluates the performance of the iSharkFin system, a machine learning technology that aims to identify shark species from dorsal fin images, and suggests its potential as a rapid field identification tool for fisheries monitoring and compliance with CITES regulations.

Summary: Per- and polyfluoroalkyl substances (PFASs) are persistent and mobile pollutants that can be emitted from various sources. This study focuses on the use of a phytoremediation pilot plant in removing PFASs from contaminated water. The pilot plant successfully reduced up to 50% of the targeted PFAAs without dependence on their physico-chemical characteristics. The presence of PFAAs in reed grasses suggests their ability to accumulate these pollutants, with concentrations up to 13 ng g(-1) ww. This research highlights the potential efficiency of phytodepuration in PFAS removal and recommends further exploration of its application in constructed wetlands for wastewater remediation.

Summary: Accurate species identification is crucial to assess biodiversity in ecosystems affected by environmental changes. The Lepidonotothen species complex, which includes notothenioid fishes in the Antarctic, has been difficult to determine. This study analyzed genetic variation among four nominal species within the complex and found no genetic separation between L. kempi and L. squamifrons. However, a genetically distinct population of L. squamifrons was found near South Georgia. Further studies will determine if this population originated from the Antarctic context and can be considered a new species. This analysis contributes to understanding the species composition in the Southern Ocean, a region threatened by climate change.

Summary: Interactions between fishing and dolphins can have negative consequences, including dolphins becoming entangled and killed by fishing gear and dolphins predating on fish caught by nets. This interaction poses danger to dolphins and leads to economic losses for fishers. A survey conducted in Italy and Croatia revealed that common bottlenose dolphins are the species most commonly involved in fishing interactions, with catch damage being the main issue. The probability of interaction varied among different fishing gears and seasons, with certain activities experiencing higher economic losses. While dolphin bycatch rates are generally low, a significant percentage of fishers reported capturing dolphins during their career. Awareness and use of acoustic deterrent devices among fishers were found to be limited.

Summary: Elasmobranchs, including two threatened smooth-hound sharks (Mustelus mustelus, Mm; Mustelus punctulatus, Mp), were studied in the central Mediterranean Sea to fill knowledge gaps on their age and growth. The use of a tagging survey, combined with standard vertebrae analysis, revealed faster growth rates and higher maximum age/size for Mm compared to Mp. The new estimates of growth and longevity have important implications for assessing the conservation status of these sharks in the Mediterranean Sea.

Summary: The decline of dissolved oxygen in the oceans could have negative impacts on marine life and biogeochemical cycles. Current models that focus on large-scale mean values may lead to inaccurate predictions. Short-term and small-scale oxygen fluctuations strongly influence marine ecosystems, but they are often neglected in large-scale modelling. Understanding the dynamics of dissolved oxygen at small relevant scales is crucial for accurate projection of the impacts of ocean and coastal deoxygenation on marine biogeochemical processes and communities.
