An attempt has been made to study the fish resources of Iril river, Manipur, based on present collection and those reported by the earlier workers. A total of 62 species of fishes representing 40 genera and 18 families has been recorded from the river. These fishes include 7 endangered (EN), 15 vulnerable (VU), 9 lower risk-near threatened (LRnt) and 3 lower risk-least concern (LRlc) species. The fish fauna of the river is a mixture of endemic hill stream, Burmese, Assamese and some widely distributed forms. The river has high fisheries potential as it harbours many commercially important food fishes and its water quality is within the tolerance limit of class 'D' water. Strategies for conservation of threatened fishes are suggested.

Abstract


An attempt has been made to study the fish resources of Iril river, Manipur, based on present collection and those reported by the earlier workers. A total of 62 species of fishes representing 40 genera and 18 families has been recorded from the river. These fishes include 7 endangered (EN), 15 vulnerable (VU), 9 lower risk-near threatened (LRnt) and 3 lower risk-least concern (LRlc) species. The fish fauna of the river is a mixture of endemic hill stream, Burmese, Assamese and some widely distributed forms. The river has high fisheries potential as it harbours many commercially important food fishes and its water quality is within the tolerance limit of class 'D' water. Strategies for conservation of threatened fishes are suggested.
