Summary: This study investigated the effect of dietary valine on the growth, composition, plasma parameters, and intestinal gene expression of largemouth bass. Increasing levels of dietary valine had positive effects on growth, but beyond a certain level, the effects declined. Valine had no significant effects on body composition, but it significantly increased intestinal antioxidant activity. Different levels of valine also had varying effects on the expression of genes related to immune response and inflammation in the intestine. These findings suggest that dietary valine can improve the immune and antioxidant capacity of largemouth bass.

Summary: This study revealed that increasing starch levels in diets negatively impacted the growth performance, intestinal health, immune and antioxidant capacity of Micropterus salmoides. The imbalances in intestinal microbiota and reduced production of short-chain fatty acids (SCFA) may contribute to the impairment of intestinal function.

Summary: This study investigated the effects of chronic hypoxia on the growth performance, antioxidant capacity, and protein turnover of largemouth bass. The results showed that chronic hypoxia decreased the growth performance, increased antioxidant capacity, and caused muscle atrophy due to altered protein turnover. Maintaining dissolved oxygen concentration above 60% DO saturation is suggested for better fish growth in aquaculture.

Summary: This study found that dietary CGA improves the health of largemouth bass by regulating gene expression related to lipid metabolism, inflammation, and antioxidant enzymes. CGA decreased levels of TG and TC in plasma, reduced NEFA in the liver, and increased mRNA expression of lipolysis enzymes in the liver. Additionally, CGA downregulated the expression of pro-inflammatory cytokines and increased antioxidant enzyme expression in largemouth bass fed HFD.

Summary: This study found that histidine deficiency in largemouth bass can suppress intestinal antioxidant capacity and induce endoplasmic-reticulum stress, leading to apoptosis, necroptosis, and inflammation. The appropriate dietary histidine requirements for juvenile largemouth bass were determined to be 1.32% to 1.47% of the diet.

Summary: This study found that feeding fermented tea residue (FT) can improve the growth performance and intestinal morphology of juvenile largemouth bass, enhance liver antioxidant capacity, and reduce the mortality rate of Aeromonas hydrophila infection. Compared with the control group, feeding FT also significantly reduced the expression of inflammatory factors in juvenile largemouth bass.

Summary: This study revealed that photoperiod duration significantly affects the growth rate and antioxidant capacity of largemouth bass. The 8L:16D group showed the best performance in terms of growth, organosomatic index, and antioxidant capacity. Longer light duration led to oxidative stress in fish liver, brain, and gill, but also boosted antioxidant responses in liver, brain, and kidney.

Summary: This study evaluated the effect of replacing fish meal with cottonseed protein concentrate on the growth, immune response, and health status of largemouth bass. The results showed that replacing more than 30% of fish meal protein with cottonseed protein concentrate had negative effects on growth, immune response, and health. High levels of cottonseed protein concentrate reduced antioxidant capacity, increased inflammation, and caused damage to the liver and intestines.

Summary: An eight-week feeding trial was conducted to study the effects of different dietary lipid sources on growth performance, fatty acid composition, and lipid metabolism-related gene expression in juvenile largemouth bass. The results showed that different lipid sources did not have a significant impact on growth performance and tissue composition. Fish fed with fish oil had higher MDA concentration, while antioxidant activities were not affected. Vegetable oils could be used as substitutes for fish oil in juvenile largemouth bass diets.

Summary: In this study, laminarin was selected as a feed additive for juvenile largemouth bass. The appropriate dosage of supplemented laminarin in the diet was investigated based on the analysis of various factors. The results showed that low levels of laminarin could act as a promising immunopotentiator without negative effects on the growth performance of the fish.

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.
