Length–weight relations of fishes (Actinopterygii) from Chilika Lagoon, India

Abstract

The LWRs of 37 fish species from Chilika Lagoon belonging to 29 genera of 24 families were estimated. The following species were examined: Acanthopagrus berda, Acanthopagrus longispinnis, Ambassis ambassis, Ambassis gymnocephalus, Anabas testudineus, Aplocheilus panchax, Atherinomorus duodecimalis, Cirrhinus reba, Daysciaena albida, Dendrophysa russelii, Eleutheronema tetradactylum, Elops machnata, Epinephelus coioides, Etroplus suratensis, Glossogobius giuris, Labeo rohita, Lutjanus indicus, Lutjanus johnii, Mystus gulio, Nematalosa nasus, Notopterus notopterus, Pelates quadrilineatus, Platycephalus indicus, Pomadasys argenteus, Pomadasys kaakan, Puntius chola, Puntius sophore, Rhabdosargus sarba, Scatophagus argus, Siganus canaliculatus, Siganus javus, Sillago vincenti, Terapon jarbua, Terapon puta, Terapon theraps, Triacanthus nieuhofii, and Xenentodon cancila. The coefficient a of the LWR ranged from 0.001 (X. cancila) to 0.032 (S. argus) while b ranged from 2.861 (T. jarbua) to 3.259 (C. reba). The study is a first report of the LWR of seven fish species not reported yet in FishBase.
