Abstract

A detailed study on the length weight relationship of Mugil cephalus in Vellar estuary was conducted between January 2004 and December 2005. Statistical tests such as regression coefficient ‘b’ and ‘a’ tests were performed to compare the b values of males and females from the hypothetical value of 3. The b value of male (2.7658) differed significantly from the hypothetical value of 3 (t = -2.8586<0.05), the b value of female (2.8586) did not differ significantly from the hypothetical value (t = -1.0158>0.05). Values of both males and females were less than 3 which proved the negative allometry growth pattern.
