Growth response and biochemical composition of rohu, Labeo rohita, fed salt-incorporated diets.

摘要

Rohu, Labeo rohita, fingerlings (av. wt. 1.6 g) were fed pelleted diets supplemented with 0, 0.5, 1.0, 1.5 and 2.0% sodium chloride (NaCl) for 120 days in 25-m3 cement tanks. The final weight gain of fish fed 0.5 and 1.0% NaCl incorporated diets was significantly (P<0.05) higher than that of the control (0% NaCl). Net protein retention and carcass protein and fat contents were higher under different treatments as compared to the control. Growth indices and carcass composition indicate inclusion of 1.0% NaCl in the diet to be beneficial for growth promotion in rohu.
