Abstract

A total of 172 samples of Rasirelliger kanagurta from Lamon Bay representing a wide range of size classes were examined to determine the length-weight relationship and sexual pattern. The length-weight relationship equation derived was W=0 01102.L298 Strength of correlation between the length and the weight of Rastrelliger kanagurta samples was relatively high (12=0 87) Parameter b was estimated at 2.98 and very close to the cube law value of 3, thus illustrating an isometric growth or parts of the body of the fish grow at a relatively constant pace This value is consistent with what other workers in the Visayas obtained. There was little difference in the values of the b and a between male and female samples of 1?astrelliget-kanagurta The sexual ratio (male-to-female) of Rastrelliger kanagurla was 1.53:1 suggesting a gonochoristic sexual pattern. The derived values of b and a of the length-weight relationship and sexual pattern are basic information and constitute key inputs to many numerical models heuristic for conservation biology and fisheries sciences.
