The growth and survival of kalbasu, Labeo calbasu, was evaluated at stocking densities of 5, 10 and 15 million spawn ha À1 in nursery rearing in concrete tanks of 50 m 2 , each for a period of 25 days. Survival of fry was density dependent and signi¢cantly higher (54.5%) at 5 million ha À1 than those at10 million ha À1 (50.1%) and15 million ha À1 (46.9%). Similarly, growth and speci¢c growth rate were inversely related to the stocking density and varied signi¢cantly among the three densities.
