Weight-length and condition factor relationship of the mullets, Liza suhviridis, L. carinata, and Valamugil cunnesius from Sandspit backwaters (Northern Arabian Sea)

Abstract

This paper reports weight-length and condition factor relationship, by sexes, of the mullets Liza subvirtdis. L. carinata, and Valamugil cunnestus ranging from 115 to 202 mm, 110 to 190 mm and 134 to 194 rom In total length, respectively, sampled from the backwaters of Sandspit during July 1991 to July 1993. Log transformed regression were used to test the growth of the specimens (N= 1241). The males of the 3 species were heavier and grew faster than the females in view of the values of regression coefficient b which were significantly higher than b = 3.0 (an ideal slope) so that the growth was allometric. Condition factor was directly proportional to the weight or length of the fishes.
