Abstract

Level of variation in tail weight and its degree of dependence on different morphometric traits were estimated in Penaeus monodon. The data on morphometric traits of a total of 165 P. monodon of four different weight groups, were subjected to stepwise regression analysis. The coefficient of variation of tail weight in all the groups was found to be higher. Correlation matrices revealed a significant relationship between the morphometric traits and tail weight, particularly in the broodstock animals. The order in which different morphometric traits entered the regression equation differed among the wieght groups. In broodstock animals, partial carapace length and carapace width determine the tail weight with high degree of accuracy {R^= 99%). Therefore, these easily measurable traits can be used as criteria in the selection of P. monodon broodstock
