ABSTRACT
The aim of the present study was to evaluate the effects of a high level of dietary fat and
polyunsaturated fatty acids on growth rate, survival and liver morphology of nase larvae
(Chondrostoma nasus L.). The results indicated that 16% of fat in feed, excessive supply of 22-carbon PUFA, and insufficient amount of MUFA may disturb lipid homeostasis in the hepatocytes
of freshwater fish, and adversely affect fish growth.
