Summary: The current population of Isogomphodon oxyrhynchus (Daggernose Shark) has experienced a 99% decrease in the last decade due to various factors, leading to its listing as Critically Endangered. This study aims to assess the health status of Daggernose sharks and compare it with other shark species to understand their ability to cope with stress. The results show significant differences in the health scores of Daggernose sharks compared to other shark species in the same region, indicating their low recovery capacity.

Summary: Historical sources provide important data for conservation efforts, and a unique archival material from the 1740s reveals valuable information about the Critically Endangered angel shark in Welsh waters. These sources identify specific areas of abundance and suggest the decline of this vulnerable species started centuries ago. The findings highlight the importance of historical material in prioritizing conservation efforts and changing our understanding of fish declines.

Summary: This study evaluates the suitability of close-kin mark-recapture (CKMR) as a demographic modelling tool and provides important ecological parameters for the critically endangered blue skate in the Celtic Sea. The study also identifies a potential critical habitat that may require protection.

Summary: This study successfully predicted the seasonal distribution and migration routes of the critically endangered scalloped hammerhead shark by integrating different data sources and using various analysis techniques. Their suitable habitats were mainly found in tropical continental shelves and deep seas, and their seasonal migration corridors were identified in different ocean basins.

Summary: By using sibling pairs, the abundance and connectivity of adult sharks in two river systems in Australia were estimated. The results showed male philopatry in the Adelaide River and high connectivity of males in the Alligator Rivers with the Adelaide River. This method allows simultaneous assessment of abundance and connectivity in rare and threatened species.

Summary: The silky shark is considered one of the least productive pelagic shark species, and understanding its growth and demographic parameters is crucial for assessing its population status in the Atlantic Ocean. Research revealed that the species has low resistance to fishing pressure, with a population decline rate of 12.7% annually under current fishing practices. Conservation measures are necessary to restore the silky shark population in the South Atlantic.

Summary: The critically endangered speartooth shark, known from northern Australia and Papua New Guinea, faces significant threats from bycatch in commercial and recreational crab pots. The limited genetic exchange among populations residing in different rivers highlights the isolation of this small population. Urgent management intervention, such as gear modifications or spatial closures, is necessary to ensure the viability of this genetically isolated population.

Summary: Regional migration of the copper shark Carcharhinus brachyurus was recorded for the first time in the Southwest Atlantic from Argentina to Brazil, with a female specimen carrying 18 developing embryos within the uterus. The total distance covered was at least 2566 km, marking the longest ever recorded for the species, and extending its northern distribution in the Southwest Atlantic.

Summary: Elasmobranch species are declining globally due to fishery activities, including in the Mediterranean Sea. Identification of nursery grounds for species like the sandbar shark is crucial for effective conservation management. This study successfully identified a nursery site for early juveniles of the sandbar shark and predicted other potential nursery areas throughout the Mediterranean Sea using a species distribution model. The findings provide valuable information for conservation efforts and future monitoring.

Summary: This study examines the negative effects of neoliberal capitalism on artisanal fishing in Chile, using qualitative methods and the coevolutionary theory. The research finds that the negative effects are the outcome of the gradual decoupling of local socioecological systems.

Summary: The study revealed that a majority of shark products marketed in Ghana are mislabelled, with some endangered shark species being substituted. This highlights the need for Ghanaian authorities to improve control measures to enforce conservation efforts.

Summary: This paper investigates credit transactions in artisanal marine fishing in Kerala, India. It examines the structure and composition of credit, interlocked credit-market and credit-labour transactions, segmentation of credit market, interest rate variations, and the reasons for high penetration of informal credit in marine fisheries. The study concludes that informal credit addresses the high income variability in marine fishing, while the formal system fails to develop credit products internalising the risk element. The traditional triadic system of trust in the informal credit system is weakening due to external forces.

Summary: The expansion of neoliberalization of fisheries in developing countries has been driven by political economic decisions. This study examines the adoption of these measures and the transformation of artisanal fishermen to entrepreneurs in the scallop fishery/aquaculture in Tongoy Bay, Chile. The results show that changes in moral economies are not automatic, the State does not directly generate expected results, and aspects of a traditional moral economy remain despite the adoption of neoliberal guidelines.

Summary: This study utilized information gathered by anglers and tourists for monitoring a Critically Endangered shark population in southern Brazil. The results showed an increase in capture records compared to the past two decades, indicating recreational fishing as an important source of information for this endangered species. Strategies for monitoring in the area were discussed.

Summary: This study used vertebral microchemistry to investigate the habitat use patterns of the longnose stingray in northern and northeastern Brazil, finding significant differences in element concentrations among sites. However, within sites, there were minimal differences among life stages and sexes. The analysis suggests that the longnose stingray likely completes much of its life cycle within each area and no nurseries were found at any site, indicating a consistent pattern across species distribution.
