The effects of partial replacement of fish meal with Roasted guar korma meal on growth, feed utilization and survival of Tilapia (Oreochromis niloticus) advance Fry

摘要

Present study was undertaken to study the effects of partial replacement of fish meal with Roasted Guar Korma on growth, feed utilization and survival of tilapia (Oreochromis niloticus). Advanced fry diet was examined. The experiments were conducted for 60 days in plastic tanks. Triplicates were maintained for each of the treatment. The five experimental diets were prepared which included a control diet (100 fish meal) and four treatment diets viz. fish meal replaced with Roasted guar korma at 25, 50, 75 and 100 of dietary protein levels respectively. The diets were formulated to provide 40 crude protein on a dry weight basis. Fish were fed with experimental dietsfor 60 days. The water quality parameters were found in the permissible range during entire experimental period. At the end of experiment it was found that the T2 treatment lead to higher weight gain (9.56 ± 0.49), SGR (1.57 ± 0.01) and PER (1.89 ± 0.02) and lowest FCR (1.65 ± 0.02) Thus, it can be concluded from the study thatRoasted guar korma is a potential protein source and can be used to substitute fish meal in the diets of Tilapia (O. niloticus) advance fry.
