Summary: Bigeye tuna and yellowfin tuna are economically important species in global pelagic fisheries, especially for tropical Pacific nations. The El Nino-Southern Oscillation (ENSO) has a significant impact on the oceanographic conditions and fishing grounds of these tuna species. This study investigates the statistical relationships between ENSO conditions and equatorial fisheries using various indices and records. The findings suggest that El Nino events have delayed and concurrent positive effects on the catch per unit effort (CPUE) of these tuna species, possibly due to enhanced recruitment and other factors.

Summary: The aim of this study was to analyze the distribution and abundance patterns of blue sharks in the southwestern Atlantic Ocean and their relationship with environmental factors. The models showed that salinity, chlorophyll-a, and temperature influenced the distribution of blue sharks. The catch per unit of fishing effort (CPUE) and the probability of presence increased mainly between March and August. Additionally, ocean depth, sea surface height, ocean fronts, and slope also influenced the CPUE and probability of occurrence of blue sharks.

Summary: Sampling designs are needed for collection of shark size composition data in order to manage shark fisheries in Central America. Tailored designs for multi-species fisheries with structured landings are necessary to minimize impact on catch landing process. Simulation results suggest that a single sampling design can be implemented for obtaining size composition estimates of common shark and non-shark species in landings with sharks.

Summary: Sharks are at risk from industrial longline fishing, especially due to their slow life histories and association with targeted tuna stocks. By analyzing shark catch records from global tuna Regional Fisheries Management Organizations (tRFMOs) using machine learning, we have identified hotspots of high shark interaction risk, including off Southwest Africa and in the Eastern Tropical Pacific. These findings can inform the development of spatial management strategies to protect threatened shark populations, and emphasize the need for coordinated data collection and dissemination by tRFMOs for effective shark management.

Summary: This research evaluated and compared the capture efficiency of crayfish using traps with different numbers of entrances. The results showed that the number of entrances did not significantly affect the catch per unit effort (CPUE), but did significantly affect the CPUE by weight. Six-entrance traps were more efficient than five-entrance traps, and the number of entrances did not significantly affect the size of the captured crayfish.

Summary: Blue shark species have been declining due to overfishing, and their stock status was evaluated using a new assessment model (CMSY++) in the South Atlantic. The results indicate that the blue shark stock may be witnessing overfishing and is being overfished. The use of different catch time series and priors had varying effects on the output results of the model.

Summary: The Socotra Archipelago in Yemen heavily relies on small-scale fishing, but the reporting of fisheries catches has been incomplete. This study reconstructs the total catches and fishing effort in the region from 1950 to 2019, finding that the officially reported catch accounts for only 20% of the total reconstructed catch. The findings suggest overexploitation of resources and highlight the importance of sustainable management for the fish stocks in the Socotra Archipelago.

Summary: In the North-Western Mediterranean Sea, European sardines show a high dietary plasticity, feeding on a wide range of prey species and sizes. They display different feeding strategies between months, either filter-feeding on relatively small prey or selectively preying on larger individuals. This flexibility allows them to adapt to the changing zooplankton community in response to both human-induced and climatic changes.

Summary: This study evaluates the impact of considering ageing error and growth variability on the determination of input sample size (ISS) in statistical catch-at-age assessment models. The results show that including these sources of uncertainty decreases the ISS determined through bootstrap methods. This indicates that there is more variability in age composition and conditional age-at-length data than previously accounted for. Including these sources of uncertainty improves the estimation of ISS and subsequently improves the quality of stock assessment models.

Summary: Estimating growth is important for fish population assessment. Integrated assessment models and the influence of misfitting size composition data have renewed interest in how growth is modeled. The available data types control how the length-at-age relationship is estimated. Estimating length-at-age is complex due to multiple sources of biological variability and difficulties in obtaining representative samples.

Summary: Small-scale fisheries are vital for global food security and cultural heritage, but the lack of information hampers effective management and mitigation of ecological impacts. This study provides the first comprehensive overview of the small-scale fishery fleet in Northern Cyprus. The fleet operates mainly over the continental shelf, using static and demersal gear types, and catches a diverse range of species, some of which are threatened. The findings can be used to improve fisheries management and conservation measures.
