Abstract

The relationships between carapace length and body weight (Log w = -0.35923+3.140792) and carapace width and body weight (Log w = -1.05521+3.271845) of males and carapace length and body weight(Log w = -0.0996+2.829127) and carapace width and body weight (Log w = -0.80516+3.020237) of females of the mud crab Scylla tranquebarica were estimated. Analysis of covariance of carapace length/carapace width - weight data between the regression equations of males and females showed highly significant difference (p < 0.05). The present results indicated that males are heavier than females at any given length / width.
