Abstract: Variation in standard length (SL) and weight parameters based on the selected regression models for Nemipterus japonicus is carried out in this study.  Comparison of nonlinear regression model coefficients have executed employing sum of squared reduction test.   Fitted models have shown differences with respect to coast, location, sex, locations within a coast.  Sex wise difference was evident in east coast while the difference was not significant in west coast.  Pooled, male and female length weight relationships have followed the isometric growth pattern while coastwise and location wise analysis showed an allometric pattern of growth. Strong negative allometric pattern of growth in east coast may be attributed to the fluctuating and diluted aquatic environment in the Bay of Bengal.
