The study revealed 125 species of fishes in Manipur of which 95 species belonging to 48 genera and 22 families have ornamental value. Fifty percent of these belonged to the family Cyprinidae, 7% to Cobitidae, 5% to Sisoridae 7% to Balitoridae, 3% to Channidae, 8% to Bagridae, 2% each to Chandidae and Mastacembelidae. Species representation in other families (16%) includes 1.6% each in Belonidae, Nandidae, Notopteridae, Psilorhynchidae, Schilbeidae and 0.8% each in Amblydpitidae, Anabantidae, Aplocheilidae, Belonidae,Chacidae, Clupeidae, Mugilidae, Symbranchidae, Siluridae and Tetradontidae. The conservation status of fishes showed that 25.6% of them have not been evaluated, 21.6% are vulnerable, 16.0% are endangered and 2.4% are critically endangered. "Low risk near threatened" category amounted to 25.6% and only 6.4% in "low risk least concern" category. Hence a cautious and regulated approach needs to be adopted while promoting ornamental fish trade. Suitable strategies for developing a viable ornamental fish trade in the state are discussed.
