Summary: The study found that chlorinated seawater at typical concentrations can affect the behavior of juvenile seabass, resulting in a decrease in the number of fish present. While seabass are attracted to areas with chlorination when food is available, they are more likely to move away once the food supply is reduced.

Summary: This study investigated the impact of adding 3% swine blood hydrolysates (BH) on muscle cellularity and the expression of molecular markers related to muscle fibre proliferation and hypertrophic growth of European seabass. The results showed that BH affected muscle growth and cellularity factors, suggesting further research on commercial-sized fish to reveal their impact on important commercial traits.

Summary: This study found that exposure to polystyrene NPs and humic acids can induce an immuno-modulatory response and activate steroidogenic stress-related pathways. While a protective anti-inflammatory effect of HA in the presence of PSNPs was observed, there appears to be a complex interaction between both components.

Summary: Marine microplastic pollution is a significant environmental problem due to the continuous growth of plastic production. This study evaluated the long-term accumulation of contaminants in fish liver caused by the ingestion of environmental microplastics. The results showed that additives and chemical contaminants from microplastics do bioaccumulate in fish liver under worst-case scenario conditions.

Summary: Large-scale electronic tagging is a powerful tool to study fish movements and migrations. We tagged European seabass in various locations and discovered that they exhibit partial migration behavior, with fidelity to specific feeding and spawning areas. These findings have important implications for fishery management and challenge the currently accepted stock structure. Further exploration is needed at both the European level and by regional managers involved in conservation outcomes.

Summary: A healthy gastrointestinal microbiota is vital for host fitness and is strongly affected by host diet. Feeding carnivorous fish plant-based diets high in non-starch polysaccharides (NSP) can lead to changes in gut microbiota composition, favoring bacterial families with carbohydrate active enzymes. Overall, the gut communities of European seabass respond to plant-based diets by adjusting to the presence of transient microorganisms with carbohydrolytic potential while maintaining a balanced core microbiota.

Summary: This study investigated the long-term effects of polyvinyl chloride (PVC) microplastics (MPs) ingestion in fish. The results showed that chronic exposure to environmentally realistic concentrations of PVC-MPs in seabass can cause toxicological harm in the liver, including oxidative stress, histopathological alterations, and changes in gene expression. The study also suggests potential genotoxic and carcinogenic effects of PVC.

Summary: The study found that temperature can significantly affect the gut microbiota and metabolism of European seabass juveniles. The abundance of certain genera in the gut microbiota and the composition of metabolites were significantly different among temperature groups. These results suggest that temperature-induced changes in the gut microbiota and metabolism may be mediated through the interaction of the microbiome and metabolic pathways.

Summary: Temperature variations significantly affect the growth and development of European seabass. Metabolites such as L-cysteine, taurocholic acid, UDP-glucose, and L-thyroxine were identified as potential markers of growth, with changes in pathways related to glucose metabolism, arginine and proline metabolism, and other key metabolic processes.

Summary: This study investigated the effects of dietary refined glycerol inclusion rate on growth performance, nitrogen and energy balances, and fish quality of juvenile European seabass. The results showed that the group fed with 25 g/kg refined glycerol had higher feed intake and weight gain compared to the other two groups. However, feed efficiency and protein utilization efficiency were similar among the three groups. The inclusion of refined glycerol increased hepato-somatic and visceral lipid-somatic indices, but did not affect proximal body composition. Additionally, fish quality decreased with storage time, but was not influenced by the dietary glycerol inclusion rate.

Summary: This study aimed to investigate the effects of dietary tryptophan supplementation on the immune condition of European seabass during stressful rearing conditions and their response to bacterial pathogens. The results showed that stress did not compromise the health indicators of seabass, but exacerbated the inflammatory response. Tryptophan had minimal effects on immune indicators but improved the inflammatory response against bacterial pathogens during stressful conditions.

Summary: This study examines the impact of alternative feed formulations on European seabass and finds that these concepts are more sustainable compared to commercial feed. Additionally, the alternative formulations do not affect fillet quality or animal welfare, which are increasingly important factors in aquaculture.

Summary: The study found that European seabass fed on diets supplemented with vitamins C, vitamin E, propolis, and phycocyanin showed improved growth performance and survival rate in extreme environments. Blood parameters, heat shock proteins, and antioxidant enzyme activities differed significantly among fish fed on different dietary supplements under heat stress conditions.

Summary: Intestinal parasitic infections (IPIs) are prevalent among preschool and school children in Egypt, with Entamoeba histolytica and Ascaris lumbricoides being the most common parasites. Risk factors for IPIs include preschool age, living in rural areas, belonging to low-income families, lack of safe drinking water, poor hand hygiene, and consumption of unwashed vegetables. Contact with pets, household reared animals, and stray animals also increase the likelihood of exposure to zoonotic parasites.

Summary: Theileria, Babesia, and Anaplasma are prevalent tick-borne pathogens worldwide, especially in tropical and subtropical regions. In Egypt, there is a high prevalence of TBPs, with significantly higher rates in LSD-positive animals compared to FMD-positive animals. Crossbreed cattle showed higher rates of Babesia and Theileria infections, while native cattle had higher rates of Anaplasma infections and co-infections with Babesia-Anaplasma and Theileria-Anaplasma. The intensity of parasitic infection was significantly higher in positive groups for LSD and FMD compared to negative groups.
