“…In many fish species, high dietary carbohydrate induced lower growth, excess lipid deposition, and decreased stress resistance383940. Therefore, fish nutritionists have tried different routes to promote the carbohydrate/glucose utilization in fish, including exploring the optimal sources and contents of dietary carbohydrate4142, adding supplementary elements (e.g. chromium)4344, or even developing gene-modified fish species4546.…”

Excess fat accumulation has been observed widely in farmed fish; therefore, efficient lipid-lowering factors have obtained high attention in the current fish nutrition studies. Dietary L-carnitine can increase fatty acid β-oxidation in mammals, but has produced contradictory results in different fish species. To date, the mechanisms of metabolic regulation of L-carnitine in fish have not been fully determined. The present study used zebrafish to investigate the systemic regulation of nutrient metabolism by dietary L-carnitine supplementation. L-carnitine significantly decreased the lipid content in liver and muscle, accompanied by increased concentrations of total and free carnitine in tissues. Meanwhile, L-carnitine enhanced mitochondrial β-oxidation activities and the expression of carnitine palmitoyltransferase 1 mRNA significantly, whereas it depressed the mRNA expression of adipogenesis-related genes. In addition, L-carnitine caused higher glycogen deposition in the fasting state, and increased and decreased the mRNA expressions of gluconeogenesis-related and glycolysis-related genes, respectively. L-carnitine also increased the hepatic expression of mTOR in the feeding state. Taken together, dietary L-carnitine supplementation decreased lipid deposition by increasing mitochondrial fatty acid β-oxidation, and is likely to promote protein synthesis. However, the L-carnitine-enhanced lipid catabolism would cause a decrease in glucose utilization. Therefore, L-carnitine has comprehensive effects on nutrient metabolism in fish.

“…Economic fish production relies on low cost commercial diet development. Increasing information on the basic nutrient requirements of this species have been reported in the last decade, and 31-34% dietary protein and 7-8% lipid were determined to be optimal for growth (Habte-Tsion et al, 2013;Li et al, 2010;Li et al, 2013;Ren et al, 2015a). The dietary EAA requirements of blunt snout bream including arginine , lysine , methionine (Liao et al, 2014), threonine and phenylalanine have been determined for this fish species.…”

“…And cellulose could not be hydrolyzed and be used as energy as fish lack cellulase in their digestive system (Chiu and Benitez ; NRC ). Therefore, lower dietary energy with higher content of cellulose could increase feed intake to maintain a relative constant energy intake for growth (Boujard and Médale ; Yamamoto et al ), which usually results in higher FCR in fish (Ren et al ). It has been reported that appropriate levels of dietary cellulose could also stimulate the movement of the intestine and thus improve the retention and absorption of nutrients in the intestine (NRC ; Tan et al ).…”

This study was conducted to investigate the effects of varying carbohydrate (CHO) fractions on growth, body composition, metabolic, and hormonal indices in juvenile black carp, Mylopharyngodon piceus. Juvenile black carp, M. piceus (average weight: 1.5 ± 0.05 g) were fed with graded levels of dietary available CHO (0.06, 10.65, 19.43, 28.84, 37.91, and 47.38%) for 9 wk, respectively. Results showed that the highest weight gain could be obtained at 24.98% dietary CHO using second‐order polynomial regression model; and optimal dietary available CHO content (28.84%) could significantly increase the final body weight and the protein efficiency ratio (PER) while reducing the feed conversion ratio (FCR) (P < 0.05). Dietary available CHO could gradually increase the hepatosomatic index, the crude lipid contents in the whole body and the glucose and triglyceride content in the plasma. The activities of glycolysis enzymes and glucose‐6‐phosphate dehydrogenase could be increased with increasing dietary available CHO. The activities of glucose‐6‐phosphatase and fructose‐1,6‐bisphosphatase were firstly decreased at 10.65% dietary available CHO and increased to stable level at 19.43% dietary available CHO. In addition, both 19.43 and 28.84% dietary available CHO could increase the adiponectin contents in the plasma of black carp, M. piceus. Meanwhile, both 19.43 and 28.84% dietary available CHO could significantly increase the mRNA expression levels of growth hormone, insulin, ghrelin, neuropeptide Y, somatostatin I, and somatostatin II in juvenile black carp, M. piceus, compared with the CHO‐deficient diet (0.06%). These results suggest that optimal inclusion of dietary CHO fractions (19.43–28.84%) could improve metabolic homeostasis and promote growth and feed efficiency in juvenile black carp, M. piceus.
