Length–weight relations of 24 fish species (Actinopterygii) from hirakud reservoir, Odisha state of India

Abstract

Length–weight relations were estimated for 24 fish species sampled from the Hirakud Reservoir (Odisha State, India): Salmostoma bacaila (Hamilton, 1822); Salmostoma phulo (Hamilton, 1822); Labeo rohita (Hamilton, 1822); Labeo bata (Hamilton, 1822); Cirrhinus reba (Hamilton, 1822); Labeo calbasu (Hamilton, 1822); Puntius sophore (Hamilton, 1822); Puntius chola (Hamilton, 1822); Pethia ticto (Hamilton, 1822); Systomus sarana (Hamilton, 1822); Pethia phutunio (Hamilton, 1822); Osteobrama cotio (Hamilton, 1822); Amblypharyngodon mola (Hamilton, 1822); Rasbora rasbora (Hamilton, 1822); Parambassis ranga (Hamilton, 1822); Parambassis lala (Hamilton, 1822); Channa punctata (Bloch, 1793); Macrognathus pancalus (Hamilton, 1822); Notopterus notopterus (Pallas, 1769); Chanda nama (Hamilton, 1822); Xenentodon cancila (Hamilton, 1822); Glossogobius giuris (Hamilton, 1822); Ompok bimaculatus (Bloch, 1794); Gudusia chapra (Hamilton, 1822). They represented 10 families: Cyprinidae (14 species), Ambassidae (2 species), Channidae, Mastacembelidae, Notopteridae, Centropomidae, Belonidae, Gobiidae, Siluridae, and Clupeidae (1 species each). The b values ranged from 2.62 to 3.44. Nine of the species displayed isometric growth (b = 3), seven species negative allometric growth (b < 3), and eight species represented positive allometric growth (b < 3). New maximum lengths are provided for two species.
