Abstract

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