Summary: This study investigated the differences in gut microbiota profiles of healthy Siamese fighting fish at different life stages. The results showed significant differences in overall bacterial profiles between young and adult fish, as well as changes in bacterial diversity with age. The study also identified variations in the abundance of Proteobacteria phylum members and their predicted functions between young and adult fish, suggesting their potential role in improving fish growth. These findings contribute to a better understanding of the role of gut microbiota and its association with host factors.

Summary: Supplementation of omega-3 fatty acids is considered valuable. Researchers analyzed 20 supplements sold in France for their fatty acid, triglyceride, and tocol content, as well as oxidative status. Results showed that only 2.5% of the supplements did not meet their omega-3 content claims. The tested products complied with established values for peroxide, p-anisidine, and Totox, indicating they were not oxidized.

Summary: This study investigated the requirements of long-chain polyunsaturated fatty acids (LC-PUFAs) in the commercially important alfonsino fish, Beryx splendens. The results showed that B. splendens obtains substantial amounts of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from its natural diet. The study also confirmed the enzymatic capabilities of fatty acid desaturase (Fads2) and elongases (Elovl5, Elovl4a, and Elovl4b) in LC-PUFA biosynthesis in B. splendens.

Summary: The assessment of trace metal content in our fish diet is important due to the adverse effect on human health. Little information is available for Southern Spain, a region characterized by high seafood intake. Nine species from the Bay of Cádiz with high commercial value were selected and found to be generally safe for consumption according to health limits provided by World, European and Spanish legislations.

Summary: The study analyzed the distribution of trace elements in sediment and five commercially important fish species in the Oman Sea, conducting ecological and human health risk assessments. Most trace elements in sediments were below safety standards, while occasionally biological effects were observed in fish tissues. The research findings suggest that consumption of the concerned species in the Oman Sea is safe for the local population.

Summary: This study investigated whether advanced M&V regression approaches offer improvements over simpler averaging approaches for peak load prediction in commercial buildings. The findings showed that regression methods did not offer a notable advantage over commonly used averaging methods, and tended to understate achieved load reductions in demand response applications for these buildings.

Summary: An estimated 1.5-2.7 billion wild fish are caught by UK commercial sea fishing fleets annually, most of which are subjected to severe stressors during capture. While fish are recognized as sentient beings in UK law, commercially caught wild fish are excluded from welfare protections, leading to major welfare issues in wild capture sea fisheries with great potential for reforms.

Summary: Seamount fish communities in the Azores, an oceanic seamount ecosystem area in the NE Atlantic, show taxonomic diversity and are influenced primarily by spatial factors such as depth. With increasing fishing pressure, certain demersal fish species have shown a decline in abundance and size, emphasizing the vulnerability of these populations to overexploitation.

Summary: Information on the population structure of Conger conger is limited, but the population found in the Azores region may represent a fishery management unit. The species shows highest abundance in depths between 300 and 600m, with sizes ranging from 14 to 260cm and larger individuals near seamounts. Tagging data indicates strong sedentary behavior in this population.

Summary: The scarcity of continental shelf and epipelagic oceanic fishes has led to commercial fishing in deeper waters, resulting in the increasing capture of vulnerable deep-sea species. Detailed information on population traits of these species is essential to reduce the impacts of fishing. The common mora has become the main deep-sea species caught in the Northeast Atlantic, showing vulnerability to overfishing due to its biological characteristics.

Summary: Sharks, rays, and skates are increasingly recognized as endangered due to their life-history characteristics, fishing pressure, and habitat degradation, with the thornback ray Raja clavata being one of the most economically important in Northwest European seas. The study analyzed approximately 25 years of data to improve understanding of habitat preferences, spatial distribution, growth patterns, sex ratios, mortality rates, and reproduction of the species. Results showed that Raja clavata is mainly caught at depths up to 250 m, with females being larger and more abundant than males, and having a long lifespan, large size, slow growth, and low natural mortality.

Summary: This study estimated the growth and mortality rates of seven exploited marine fishes in Azorean waters based on length-frequency data. The results showed that these fishes have relatively large sizes, slow growth, and low natural mortality rates, indicating high vulnerability to overfishing. Therefore, assessment and management initiatives are highly encouraged to ensure the sustainability of the resources.

Summary: Combining scientific data with fishers' knowledge is a good approach for marine ecosystem conservation decisions. This study assessed the knowledge of fishers in the Azores about six important marine species and compared it to scientific information. The findings showed a reasonable agreement between fishers' knowledge and scientific literature, highlighting the value of experiential knowledge when scientific information is limited. However, further research is needed for more reliable and consistent results.

Summary: This study analyzed scientific survey and fishery-dependent data over the past 30 years to understand the abundance, spatial distribution, and life history of the silver scabbardfish in the Azores. The species was found to prefer depths of 200-400 m, close to seamounts and islands, and sandy bottoms. The population was dominated by females and showed slow growth rates. The abundance of the species has been declining with a high exploitation rate in the region. Lack of management measures and its vulnerability could lead to the depletion of this species.

Summary: Small-scale fisheries play a critical role in food security and contribute to nearly half of reported global fish catches. However, the status of most small-scale fisheries stocks is still poor. In this study, three different length-based assessment methods were applied to predict fisheries stock sustainability in the Azores, and the results showed that 45% of the stocks were classified as sustainable, 33% as possible rebuilding/overfished, and 22% as overfishing/overfished. Sensitivity analysis indicated that biases on the source of initial life-history parameters have a stronger influence on the reference points of conservation and management recommendations were provided based on the results.

Summary: Plesionika edwardsii is a cosmopolitan species found in cold temperate and subarctic waters, with the Azores being its second most common habitat where populations remain unexploited. Research in the area revealed that this species is most abundant between 100 and 600 m depth, with females being larger and more abundant than males, and ovigerous females mainly appearing in winter with a 25 mm size at 50% maturity. The study also highlighted high variability in distribution patterns and life-history traits, emphasizing the need for further investigation into oceanographic processes associated with this species and a precautionary approach to commercial fisheries.
