Length-weight relationship and growth of Labeo bata

Abstract

This study was executed to elucidate the length-weight relationship (LWR) yet the annual condition of the Labeo bata (Hamilton, 1822), an immensely important fishery of Bangladesh.  Overall, 447 specimens employed during this study were collected by using traditional fishing gear (cast net). Total length (TL) of each individual was measured closest to 0.1 cm and whole body-weight (BW) nearest to 0.01 g accuracy, respectively. The values of ‘b’ indicated negative allometric growth patterns for males (b= 2.913) whilst an isometric value for females (b= 3.038) and both sexes (b= 2.989), respectively. Furthermore, the Fulton condition factor value was highest for males (0.98) over females (0.97). All of these outcomes will bring advanced scientific knowledge and will be helpful for sustainable management of this least concern fish species (Labeo bata) in the river ecosystem of Bangladesh.
