Abstract
Six purified diets were formulated and prepared using casein, starch, flshand- groundnut oil mixture ( 1 : 1 ratio), vitamins, minerals and other additives, with the protein content varying from 20 to 70%, to study the protein requirement of the postlarvae fPL 1 to PL 42) of the prawn Penaeus indicus. The results of the feeding experiments conducted separately on group I (PLl to PLIO), group II (PLll to PL25) and group III (PL27 to PL42) for a duration of 10, 15 and 15 days, respectively, showed that the growth of group I postlarvae increased with the increasing protein content of the diet up to 40% and declined thereafter. The growth obtained by the diet with 40% protein was highly significant (P <C 0.01). In group II postlarvae, the protein requirement was between 30 and 50%. In group HI postlarvae, maximum growth was obtained with the diet with 30% protein and it was significantly different (P <C 0.05) from the performances of the other diets. It is concluded that the dietary protein requirement of postlarvae decreases from 40%in the initial stages to 30% as they grow to advanced stages. Similarly, the rate of growth was found to be relatively faster in the young postlarvae.
