Abstract

A 84-days experiment was conducted to observe the effects of different feeds rich with various types of fats on selected biochemical parameters of Channa striatus grow-outs. There were seven treatments (F1, L3HUF; F2, H3HUF; F3, MUSOL; F4, LINOL; F5, MIXOL; F6, SATOL and F7, NATFO), fed to fish (avg. wt., 27.36 ± 0.09 to 32.54 ± 0.41 g). Results showed that the variation in liver glycogen content was recorded on addition of different fat content in the diet. Activity of intestine protease recorded significantly (p<0.05) on addition of various fat content in the diet. It is found that the variation in intestine amylase varied significantly (p<0.05) in F1, F3 and F5 feeding trials. Intestine lipase varied significantly on addition of various fat content in all the feeding trials except in NATFO. The intestine cellulase was very poor in this fish and does not varied significantly (p > 0.5) on addition of different fat content in the diet. In case of F1 and F2 there was no activity recorded till end. Results suggests that dietary fat has direct role in the alteration of biochemical parameters especially intestinal lipase which showed drastic variation in the activity in this species of aquaculture importance.
