An 82-day study was conducted to assess the effect of the dietary lipid levels on growth performance, feed utilization, lipid deposition, and hepatopancreas lipometabolism of large-sized common carp (Cyprinus carpio). Six isonitrogenous (300 g/kg protein) pelletized diets with different dietary lipid levels (30, 60, 90, 120, 150, and 180 g/kg) were fed in triplicate to fish groups with 75 individuals (with an initial mean weight of 247.00 ± 16.67 g). The results showed that there was a significant increase in weight gain (WG) rate (WGR), specific growth rate (SGR), and protein efficiency ratio (PER) as dietary lipid levels increased from 30 to 60 g/kg (p < 0.05) and then there was a decline. Feed conversion rate (FCR) was observed to be significantly lower in 60 g/kg lipid treatments (p < 0.05). Muscle crude protein contents were obtained to be significantly higher in 60 and 90 g/kg treatments (p < 0.05). The crude lipid content in the hepatopancreas increased significantly with an increase in dietary lipid levels (p < 0.05). The expression of lipoprotein lipase (LPL) and carnitine palmitoyltransferase-1 (CPT1) in the hepatopancreas was significantly downregulated with an increase in dietary lipid levels while the expression of growth hormone (GH), insulin-like growth factor-1 (IGF-1), fatty acid synthase (FAS), acetyl-CoA carboxylase-1 (ACC-1), and sterol regulatory element binding protein (SREBP) was upregulated first in 30 and 60 g/kg lipid treatments and then downregulated significantly in other treatments. The results revealed that excess dietary lipid supplements (more than 60 g/kg) would inhibit WG and would aggravate the lipid decomposition in the hepatopancreas. Based on WGR and FCR, the dietary lipid levels of 59.5 and 70.4 g/kg were optimal for growth performance and feed utilization of large-sized common carp.

Body Protein

An 8-week feeding trial was conducted to determine the optimum dietary protein and lipid levels for growth, feed utilization and body composition of goldfish, Carassius auratus juveniles (1.66 ± 0.018 g). Six diets containing two protein levels (300 and 400 g/kg) and three lipid levels (40, 80 and 120 g/kg) were formulated. Fifteen fish were randomly allotted to 18 aquaria (0.6 × 0.3 × 0.45 m) and fed to apparent satiation. The results showed that weight gain and specific growth rate (SGR) increased in response to higher dietary proteins with highest weight gain and SGR recorded in diet containing 400 g/kg protein with 80 g/kg lipid. Both feed intake (FI) and protein efficiency ratio (PER) were dependent on dietary protein and lipid level (P less than 0.05). Lipid retention (LR) was negatively correlated while hepatosomatic index (HSI) and viscerosomatic index (VSI) was positively correlated with dietary lipid levels. Whole body protein content decreased (P less than 0.05) while, lipid content increased with increasing dietary lipid at each protein level. Second-order polynomial regression also revealed diet containing 400 g/kg protein level and 80 g/kg lipid level optimal for the growth and feed utilization of juvenile goldfish, C. auratus.
