Abstract

The performance of I and II meiotic triploids and control oysters (Crassostrea madrasensis) reared at Tuticorin Bay was compared to determine if the improvements in the growth of edible oysters were additive to faster growth in triploids. After a grow-out period of 12 months, both mean whole weights and shell heights were in order Imeiotic triploid4IImeiotic triploid control. Mean whole weights and shell height of diferent oyster lines were all signi¢cantly different (Po0.05). On an average, larger morphological traits indicated that growth improvements from triploids were additive, and throughout the study triploid oystersmaintained faster growth rate than their diploid siblings. Condition index and adductormuscle diameter of both triploids were higher than those of control.
