Abstract
Chitala chitala (Hamilton, 1822) is an indigenous fish of freshwater lotic ecosystem belonging to the family Notopteridae of the Order Osteoglossiformes. This fish species has relatively larger market demand presumably because of having rich lipo-proteinaceous tissue at the ventral side of the body. Wild variety of Chitala chitala (Hamilton, 1822) was identified at the lower reach of Muhuri river of Tripura, India. As per IUCN criteria this fauna may be considered near threatened fish species in North-east India in general and Tripura in particular. In various corners of India this species was considered as preferred fish species. Morphometric character of the fish specimen showed hump-like structure just behind the head area, bar, transverse, silver at dorsal body area. Greatly compressed body, laterally, oblong and tapering towards caudal area. Dorsal fin, significantly smaller. Anal fin, very long; originated with the fusion of pelvic fin and also ended by fusion with caudal fin. Scales, tiny, sharp at ventral area of head. A specific fin formula was noticed in Chitala chitala (Hamilton, 1822).
