The aim of this study was to determine the influence of lipid level in formulated feeds on growth, survival, hepatosomatic index (HSI) and proximate composition of liver and muscle in Brazilian codling. Three different experimental diets (40% crude protein) were made using 3%, 6% and 10% of fish oil, obtaining 5%, 8% and 11% of crude lipid, respectively. Daily feeding rate was kept at 3% of fish body weight. At the end of the 40 day trial, the fish were weighed and samples from muscle and liver were taken. The highest weight gain was obtained at the lowest dietary lipid level. The lowest survival rate and greater HSI was found in the group fed with the highest lipid level. Significant differences (P |
