Length–weight relationships of three carangid fish species Alepes vari (Cuvier, 1833), Uraspis uraspis (Günther, 1860) and Carangiodes oblongus (Cuvier, 1833) from the Bay of Bengal coast, Bangladesh

Abstract

Length–weight relationships (LWRs) were determined for three Carangid fish, [Alepes vari (Cuvier, 1833), Uraspis uraspis (Günther, 1860) and Carangiodes oblongus (Cuvier, 1833)] inhabiting in the Bay of Bengal coast, Bangladesh. A total of 147 individuals of three species were sampled from four different sampling points of the Bay of Bengal coast, Bangladesh and examined from April 2017 to October 2017. Fishermen operated beach seine nets (mesh size BSN, 30 mm) and drift gillnet (10.5 cm) twice in each sampling campaign to catch the studied species. The calculated value for parameter “b” of LWRs were 3.003, 2.945 and 2.980 for A. vari, U.uraspis and C. oblongus, respectively.
