Summary: Efficient aquaculture management requires optimizing feed intake to balance fish productivity and environmental waste. Automated feeders with daily feed intake (DFI) prediction capabilities are popular for achieving this balance. This study optimized DFI prediction using various learning algorithms and nonlinear functional forms, showing that feed selection, fish characteristics, and environmental factors significantly impact DFI. Nonlinear models demonstrated higher accuracy, and the use of adaptive algorithms facilitated the development of effective DFI prediction models.

Summary: This study examined the taste attractiveness of 21 amino acids and 4 taste substances for barramundi, and investigated their feeding behavior. The results showed that citric acid, cysteine, and alanine were palatable, while sucrose and 7 amino acids had an aversive taste. Barramundi often made repeated grasps and rejections of pellets, leading to the destruction of the pellets.

Summary: This study assessed the impacts of different stocking densities on Asian seabass growth, survival rate and economic efficiency. The results showed no significant difference in final length, survival rate and feed conversion ratio among the treatments. However, the stocking density of 6 fish/m2 resulted in significantly higher final weight growth and daily weight gain compared to the stocking density of 10 fish/m2. The treatment of 6 fish/m2 also had the highest capital efficiency.

Summary: This study demonstrates that the supplementation of Astragalus polysaccharides (APS) can have beneficial effects on the growth, health, and resistance to Vibrio harveyi of Asian seabass. APS supplementation at 0.10% to 0.20% significantly improved the growth performance, digestive enzyme activity, and intestinal health of Asian seabass. Furthermore, APS supplementation enhanced the antioxidant capacity and immune function of the fish. However, a higher concentration of APS (0.20%) had adverse effects on the growth and immune response of Asian seabass.

Summary: The relationship between individual growth rate and the timing of sex change plays a significant role in reproductive output and population productivity. Fast growth is associated with a younger age at sex change, but not necessarily a smaller size at sex change. Individuals that grow faster, particularly as large females, contribute more to population fecundity and ultimately obtain higher fitness.

Summary: This study evaluates the probiotic potential of GM-Lac, a mixture of four lactic acid bacteria strains, in fish aquaculture. Each strain demonstrated antimicrobial activity against common aquaculture pathogens. Fish fed with GM-Lac exhibited improved growth performance, intestinal health, muscle amino acid composition, and disease resistance. The study concludes that GM-Lac is recommended as a probiotic supplement in aquaculture practice.

Summary: The study investigated the impact of seasonal water temperature changes on the utilization of dietary fatty acids in Atlantic salmon, as well as the suitability of different types of terrestrial oils in terms of metabolic energy provision and final product quality. Results showed the significant influence of seasonally tailored diets on the growth and fatty acid composition of Atlantic salmon, with high terrestrial oil inclusion diets enhancing the deposition of n-3 LC PUFA in the fish.

Summary: In diets with varying levels of lipids and omega-3, higher lipid and omega-3 content contributed to increased weight and growth in Atlantic salmon postsmolts. Hypoxia was shown to reduce growth in the fish, but high lipid diets improved protein and energy retention, as well as lipid and LC-PUFA digestibility. High omega-3 diets also improved LC-PUFA retention and digestibility, indicating the importance of energy intake under hypoxic conditions in nutritional responses.

Summary: This study aimed to investigate the effects of different levels of EPA and DHA on the hepatic metabolic health of Atlantic salmon reared in sea cages. The results showed that feeding low levels of EPA+DHA altered hepatic energy metabolism, resulting in reduced beta-oxidation and compensated by increased activity in alternative energy pathways. Increased acylcarnitines in the liver indicated issues with lipid metabolism. Fish fed higher levels of EPA+DHA showed improved growth compared to other groups.

Summary: This study investigated the growth and feed utilization efficiency of redclaw crayfish fed with different experimental diets. The results showed no significant differences among diets in terms of growth and feed utilization efficiency. Redclaw crayfish performed well with FM-free vegetable diets and poultry by-product meal-based diets. The essential amino acids lysine, arginine, and leucine were found to be the most important in the muscle of redclaw crayfish.

Summary: Substantial progress has been made in improving aquaculture feeds and feeding technologies over the past 20 years. The feed conversion efficiency and ingredient sustainability have improved significantly. However, there is still a need to define the requirements, especially for species farmed in the developing world. Precision nutrition approach and diversification of ingredient options are essential for sustainable aquaculture. The use of automated feeding systems is increasing in advanced aquaculture systems, while manual labor is still prevalent in the developing world.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
