Summary: This study investigated the effects of dietary carbohydrate level on nutrient metabolism in largemouth bass juveniles. The results showed that feeding a high carbohydrate diet led to the lowest weight gain and increased levels of pyruvate, lactic acid, triglyceride, and free fatty acids in the blood plasma. The high carbohydrate diet also caused vacuolation, glycogen granule, and lipid accumulation in the fish liver. However, the activities of hepatic glycolysis enzymes did not differ significantly among the different diets. Additionally, the expression of glucose and lipid metabolism-related genes and the activities of hepatic enzymes involved in carbohydrate and lipid metabolism were up-regulated with increasing dietary carbohydrate level. Metabolomics analysis further revealed that glucose and lipid metabolism, as well as the antioxidant defense system, were influenced by the dietary carbohydrate level. The accumulation of carbohydrate metabolites, unsaturated fatty acids, cholesterol, and antioxidant functional substances was observed in the high carbohydrate diet group. Overall, this study provides detailed insights into the metabolite conversion in largemouth bass fed a high carbohydrate diet.

Summary: This study aimed to elucidate the mechanism of energy metabolism in largemouth bass. Short-term starvation led to an up-regulation of crude protein in the liver, while reducing the liver index, visceral index, and hepatic glycogen content. Gene expression analysis showed down-regulation of insulin-like growth factor 1 and TOR pathway genes, and up-regulation of lipolysis-related genes, while inhibiting lipogenesis and gluconeogenesis. Short-term starvation effectively depleted hepatic glycogen accumulation and mobilized it for energy.

Summary: This study evaluated the influence of dietary lysophospholipids combined with 1% fish oil reduction on the growth and hepatic lipid metabolism of largemouth bass. The results showed that adding 0.1% lysophospholipids to the diet improved digestive enzyme activity, growth performance, and liver enzyme activity in largemouth bass.

Summary: This study aimed to investigate the effects of graded replacing fish meal with spray dried chicken plasma (SDCP) on the growth performance, feed utilization, and antioxidant capacity of largemouth bass. The results showed that the replacement of fish meal did not significantly influence the growth rate and feed intake of the fish. Additionally, the inclusion of SDCP increased the crude protein content and protein retention rate in various body parts of the fish, as well as the lipid retention rate. Moreover, the replacement of fish meal with SDCP reduced the content of lipid peroxidation product and increased the total antioxidant capacity and catalase activity in the fish.

Summary: This study reveals that DHA can improve the ability of fish to utilize high-carbohydrate diets by promoting glucose metabolism in adipose tissue. DHA increases glucose uptake in adipose tissue, reduces blood glucose levels, and inhibits excessive accumulation of abdominal fat through reprogramming metabolic processes. DHA also attenuates inflammation in adipose tissue.

Summary: This study aimed to explore the effects of mannan oligosaccharides (MOS) on metabolic disorders induced by high-carbohydrate diet in largemouth bass. The results showed that supplementation of MOS in high carbohydrate diet could improve the liver health in largemouth bass by reducing lipid content and liver fibrosis, but it did not alleviate glucose metabolism disorders.

Summary: This study investigated the effects and mechanism of berberine on high carbohydrate diet induced intestinal damages in largemouth bass. The results showed that dietary berberine improved the physical indexes and reduced tissue damages in the intestine of largemouth bass. Berberine also alleviated inflammation and ER stress, as well as suppressed lipogenesis and promoted lipolysis through AMPK/SREBP1-mediated lipid metabolism. Furthermore, berberine promoted hepatic lipid catabolism and glycolysis to reduce systematic lipid deposition in largemouth bass. Therefore, berberine has the potential to enhance the intestinal function of aquaculture species as an aquafeed additive.

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: 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.
