Abstract



Penaeus indicus was subjected to four different levels of feeding with live earthworm. The growth increments irrespective of the feeding levels did not show any decreasing trend throughout the experimental period. This is probably because the growing prawns were getting more or less constant proportion of food to body-weight although it varied with the frequency of feeding. Even under this condition if the growth pattern of the species was that of von Bertalanffy, the growth increments would have decreased constantly with time. This study also confirmed the high growth potential of this species of prawn, which could well be exploited to produce fast growing individuals. Quality and quantity of food plays a decisive role in penaeid prawns in view of their voracious feeding habit and thus form the main basis for high-density prawn culture
