Summary: This study investigated the associative behavior of skipjack, yellowfin, and bigeye tuna within multi-species aggregations associated with drifting fish aggregating devices in the western Indian Ocean. Results showed differences in residence and absence times at different temporal scales and regions, providing valuable insights for the science-based management of dFADs in the Indian Ocean.

Summary: This study investigated the interannual variability of yellowfin and bigeye tuna catches in the southwestern tropical Indian Ocean over 25 years and found that the catch amounts in the northern region are related to temperature, salinity, and current variability. The catch variability in the northern region is more closely related to El Nino-Southern Oscillation.

Summary: By using scientific echosounders, researchers investigated the distribution and in situ target strength of skipjack tuna and juvenile yellowfin tuna associated with light fish-aggregating devices in the South China Sea. The study found that the presence of luring lamps influenced the acoustic signals and density of tuna, providing insights into their behavior under different environmental conditions. These findings can be valuable for estimating tuna abundance, monitoring population trends, and understanding their ecological interactions.

Summary: This study investigated the changes in antioxidation ability of yellowfin tuna under different salinity environments and found that low salinity may influence the antioxidant function of yellowfin tuna. However, yellowfin tuna juveniles have strong adaptability to a salinity of 29 parts per thousand. Nevertheless, excessive stress may deplete the body's reserves and reduce its resistance.

Summary: The skipjack tuna is a mesopredator fish species with seasonal abundance in waters off Taiwan. This study used stomach content analysis and stable isotope analysis to evaluate the feeding ecology of skipjack tuna in different regions off Taiwan. The results showed that skipjack tuna is a generalist predator, but its diet composition varied between western and eastern Taiwan. The study also found that the estimated trophic position of skipjack tuna was slightly higher in western Taiwan, and that the size dynamics of predator-prey relationships differed between the two regions.

Summary: Skipjack tuna is one of the most commercially important marine fish species, and its stocks in the Indian Ocean are potentially significantly affected by climate oscillations. This study investigated the relationship between climatic indices and skipjack tuna catch per unit effort (CPUE), and established a predictive model to optimize the utilization of this species in the Indian Ocean.

Summary: The study reveals that the greening phenomenon in tuna muscle after heating is caused by a reaction between Cys-10 residue and free Cys, independent of TMAO. The presence of catalase promotes this reaction, suggesting the involvement of H2O2 as an intermediate substance. Furthermore, the greening phenomenon is not exclusive to tuna muscle, but can occur in other muscle systems as well.

Summary: Yellowfin tuna are highly exploited in the Indian Ocean, with their stock structure not well understood. This study collected otoliths from young-of-the-year yellowfin tuna in major nursery areas to explore the spatial distribution of trace elements and stable isotopes, revealing significant regional variations in the chemical signatures of the otoliths. The study demonstrates that these baseline chemical signatures can be used as natural tags to determine nursery origins in the Indian Ocean.

Summary: This study investigated the extraction of collagens from skipjack tuna tail tendons and evaluated their physiochemical properties and characteristics. The collagens were extracted using vinegar, acetic acid, and pepsin. The results showed that the collagens had good solubility, especially at low pH. The FTIR spectrum indicated the presence of various functional groups, and SEM analysis revealed the microstructure of the collagen surface.

Summary: The study found potential interspecific competition among three species of Seychelles spiny lobsters, with P. penicillatus showing greater adaptive capacity. Results suggest that competition between Seychelles spiny lobsters may increase in the future as the frequency and severity of bleaching events is predicted to increase with climate change.

Summary: The study found that lipid extraction with dichloromethane did not affect mercury concentrations in tropical tuna, likely due to the affinity of methylmercury to proteins in tuna flesh, the low lipid content in tropical tuna muscle samples, and the non-polar nature of dichloromethane. This suggests that lipid-free samples commonly used in tropical tuna foraging ecology research can be equivalently used to document mercury concentrations at a global scale.

Summary: Omega-3, essential nutritional compounds for humans, mainly come from seafood, particularly fish. In Eastern Boundary Upwelling Systems, nutrients are advected to support phytoplankton proliferation. With climate change projections, phytoplankton community in EBUS may change, leading to a decreased supply of omega-3 for human consumption.

Summary: The study found that storage temperature and duration significantly influenced the content of EPA and DHA fatty acids in fish, with faster loss observed at 18-20 degrees Celsius. Additionally, rapid and cool handling post-fishing is recommended to preserve the freshness and food safety of the fatty acids.

Summary: This study investigated the lipid composition during gonad development of swordfish. The results showed that lipid classes and fatty acid concentrations remained unchanged during testes maturation, but followed an inverted U-shaped relationship with ovarian maturation. Swordfish gonads might represent a good food source for humans.

Summary: Small pelagic fishes such as sardine and anchovy have high levels of essential fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The bioavailability of these fatty acids may depend on their esterification to polar or neutral lipids. This study compared the EPA and DHA content in neutral and polar lipids in sardine and anchovy fillets, finding that sardine had higher overall EPA+DHA content, while anchovy had higher DHA esterified to polar lipids. The study also highlighted the importance of red muscle in providing essential dietary fatty acids and the need to consider it in nutrition studies.

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: Recent advances in genomics have greatly contributed to the assessment of fish stocks by providing precise identification of genetic boundaries. This study used a genotyping-by-sequencing approach to reveal the existence of an additional genetic cluster of blackspot seabream in the northeast Atlantic, which was not previously identified. Factors such as ocean circulation patterns and local upwelling may play a role in the genetic differentiation observed in this study.

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: This study examines the acoustic properties of skipjack tuna and Atlantic mackerel, both bladderless pelagic fish species, and explains the significant differences observed. The research shows that the differences in material properties of their tissues predict a more than 10 dB greater reduced target strength in skipjack compared to mackerel at certain frequencies.

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.
