Summary: High-throughput sequencing was used to study bacterial diversity in a Biofloc aquaculture system and its effect on digestive enzyme activity in Nile tilapia. The study found that the biofloc group had higher bacterial diversity and a different composition compared to the control group. Certain bacterial genera correlated significantly with enzyme activity. The biofloc microbiota provided enzymes that improved digestion and nutrient assimilation in the fish.

Summary: This study evaluated the environmental sustainability of Nile tilapia net-cage farms of different sizes using environmental sustainability indicators and benchmarks. Results showed that environmental sustainability is independent of farm size, with factors like feed composition, management techniques, and water temperature being more critical. The use of benchmarking tools can provide reference values for each environmental sustainability indicator, allowing improvements to reach desirable states.

Summary: This study revealed that external mucosal surfaces of fish harbor complex microbial communities dominated by various bacterial phyla. The composition of these communities differed between water and fish species, suggesting a non-passive reflection of surrounding environment. Each species exhibited unique organ-specific bacterial communities on the skin and gill, with core taxa shared between species and water, highlighting potential beneficial and opportunistic pathogens.

Summary: A raw starch digesting ?-amylase, AMY-T, was identified in the intestine of Nile tilapia. It showed high catalytic efficiency and adsorption towards various carbohydrates, with stable endo-activity under a wide range of pH and solvent conditions. Characterization revealed the end products of raw starch hydrolysis and the catalytic attack pattern on starch granules, suggesting high potential for industrial use.

Summary: This study tested the effectiveness of a mixed-sex strategy in tilapia farming compared to the commonly used MT-treated mono-sex system. The results showed no significant differences in production and quality between the two strategies. However, the additional costs of the mixed-sex strategy resulted in lower profits, which could be mitigated by selling a portion of the removed females at a premium price.

Summary: This study provides an integrated description of the morphology of the esophagus and stomach in Nile tilapia. The stomach is divided into five distinct zones and histological analysis revealed the presence of mucins in the esophagus and stomach. These findings contribute to a better understanding of the growth, health status, and comparison of different conditions in Nile tilapia.

Summary: Recent advances in microalgae biotechnology have shown that microorganisms like Chlorella vulgaris contain beneficial bioactive molecules that can be used in functional beverages to protect tissues from oxidative damage. In vitro and in vivo tests demonstrated the protective effects of a functional alcoholic beverage made from C. vulgaris biomass in rat brains. The beverage not only improved cortical spreading depression but also helped control weight gain in animals, suggesting a potential physiological role in protecting brain cells from the effects of alcohol consumption.
