Abstract

The length–weight relationships (LWRs) of four indigenous fish species; namely Parambassis baculis (Hamilton, 1822); Pethia gelius (Hamilton, 1822); Channa stewartii (Playfair, 1867); and Leiodon cutcutia (Hamilton, 1822) collected from the Ranganadi River in Assam, and the Simsang and Kynshi River in Meghalaya are presented in the present study. The value of the parameter b recorded for P. baculis = 3.347; P. gelius = 3.924; C. stewartii = 2.979; and L. cutcutia = 3.205, with regression coefficients (r2) of 0.993, 0.963, 0.983 and 0.955, respectively. Parameter a was 0.0124 for P. baculis, 0.0037 for P. gelius, 0.0098 for C. stewartii and 0.0273 for L. cutcutia. As information on the LWRs of these fish species is not available in the FishBase database, it should assist future researchers to better analyse the stock of these fishes.
