Identification of an organism is mandatory for classification and taxonomical studies. Due to identification problems that exist between the fish species there is need of characterisation of morphometric and meristic characters of fish species. In present studies the fish species taken is Mystus bleekeri. A total of 15 species of M. bleekeri are taken from the Nermada River. The identification of Mystus species and confirmation of the identified species is done by using morphometric meristic charcterstics features. The linear regression analysis is done. The correlation between the total length and other parameters is found highest for fork length and lowest for pre pelvic length. There is the propotional increase in growth with the increase in total length. The results show positive allometry. The study of morphometric relationships is required for the taxonomic and phylogentic studies.
