Abstract

The length-weight relationship and relative condition factor of S. phasa, collected from Loitraghat and Patenga fish landing centers of Chittagong, were studied between December, 1992 and November, 1993. The values of the exponent in the length-weight equations estimated separately for both sexes indicated t hat the differences in the exponential indices of total length in males and females were statistically not significant. The general equation, thus, was derived from the data pooled from both the sexes. The unified equation showed that the general length-weight relationship in S. phasa is nearly close to the cube law. The general length-weight relationship found to be log W = -2.524 + 3.149 log TL or W = 0.002993.149. The mean values of relative condition factor (Kn) were found to be 1.0057+0.1169 and 1.00163+0.0576 in male and female respectively.
