A comparative study of quality of eggs produced\ud from wild and captive spawners of Penaeus\ud indicus and their bacterial populations

By A S Sahul Hameed

Abstract

Based on the morphology, the eggs of Penaeus indicus were classified into\ud five different types : type A eggs with normal development; type B eggs with\ud delayed or abnormal development; type C eggs with undifferentiated\ud embryonic mass; type D eggs with unequal cells and type E unfertilised eggs\ud with orange colour. The incidence of abnormal eggs was high in eyestalk\ud ablated pond reared prawn. Statistical analysis revealed a significant\ud difference in the percentage of abnormal eggs, hatching rate and bacterial\ud numbers between eyestalk ablated pond reared and wild females of prawn.\ud A significant correlation was found between the bacterial numbers and\ud percentage of abnormal eggs, and bacterial numbers and hatching rate of eggs
