Distribution of an endangered fish species, Chaca chaca (Ham.- Buch.), in Arunachal Pradesh, India: A biodiversity hot spot

Chaca chaca (Ham.- Buch.) belongs to the family Chacidae. Chaca is the only genus in the family Chacidae and the only species reported from the Indian sub-continent. In India, this fish is available at restricted area. As per the report of NBFGR (2010) and IUCN (2013), a limited population and less number of individuals are found which is pushing this species towards extinction and the status of this fish is endangered. Lack of proper database on the distribution of C. chaca is a hurdle for the fish managers and fish conservators for its study. The present data of C. chaca collected from the various districts of Arunachal Pradesh help to formulate the management plan for in-situ or ex-situ conservation
