The ichthyofauna of upper the lake Bhopal was dominated by cypriniformes (29 species) followed by ophiocephaliformes (5 species), perciformes (4 species) and others orders. The study indicates that many species in the lake are in decline or even have disappeared in comparison to the previously recorded data. The main reasons behind the decline of species are habitat destruction, introduction of exotic species, pollution and over-fishing. This disappearance of some of the highly conspicuous species must be a cause of concern to ichthyologists and there is an immediate need of their conservation.
