AbstractThe present study concerned with three Mystus species, Mystusvittatus, Mystusgulio, Mystuscavasius. Mystus species are small indigenous fresh water fishes with high nutritional value. Morphology of fishes has been the primary source of information for taxonomic and evolutionary studies. In the present study total 16 morphometric external characters were analysed and the correlation of body parts with total length and head length were analysed. The differences in morphometric characters is due to geographical and environmental variations are also observed. The mean value of the meristic counts are also studied in three species.
Keywords: Mystusvittatus; Mystusgulio; Mystuscavasius; Morphometric Characters; Meristic Counts.
