Abstract: The Catlacatla in the MunjSagartalabDhar was studied for its weight- length relationship for the period of Nov.2006 to Oct.2008. Length Weight relationship (LWR) is useful in fishery management for both applied and basic uses. In the present study the valueb for Catlacatlawas 2.897 Statistical method such as co-relation, smoothing of data, regression and cluster analysis and polynomial curve fitting are helpful in predicting and planning of the ecosystem. The Second order polynomial was found to be a best fit for LWR in present study
