Effect of feed and fertilizers on the growth and body composition of air breathing fishes Channa striata and Pangasius hypophthalamus fry.

Experiments were conducted to evaluate the response of five treatments to observe the growth performance and meat composition of Channa striata and Pangasius hypophthalmus advanced fry for the period of 60 days. Composition of nitrogen in different experiments treatment with different combinations of supplementary feed. The pond was supplemented with 0.2g N/100g body weight fertilizers and supplementary feed, the source of which are different. The treatment was cow dung, pig dung, nitrophos, supplementary feed and probiotics in 5 treatments. The highest fish production was recorded in treatment of supplementary with probiotics. Among the species channa goes to better result compare with the pangus. The present study revealed that there is a significant difference (P < 0.05) between body composition of the studied fish species. Moreover, variations also exist between the fishes of the same species for all the constituents.
