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.
