    Biodiversity, Threat Status and Conservation Priority of Icthyo-fauna of River Gomti at Lucknow Region, India

    ABSTRACT
    The present study was carried out to know the current status of vanishing icthyo-faunal biodiversity in river Gomti, a tributary of river Ganga at Lucknow region covering a stretch of about 940 km. The results of this study revealed the occurrence of 56 species belonging to 41 genera, 9 orders and 21 families. Among the collected species the maximum number of species recorded was under the Order Cypriniformes (33.91%) followed by Siluriformes (30.32%), Perciformes (17.85%), Ophiocephaliformes (5.37%), Mastacembeliformes (3.59%), Clupeiformes (3.59%), Mugiliformes (1.79%), Beloniformes (1.79%) and Tetraodontiformes (1.79%). According to IUCN most of the species (46) are under Least Count, while some others including Ompok bimaculatus, Ompok pabda, Wallago attu, Bagarius bagarius, and Ailia coila are in Near Threatened category. Cyprinus carpio, Ctenopharyngodon idellus, Oreochromis mossambicus and Hypophthalmichthys molitrix are not counted because exotic species and Anabas testudines falls into data-deficient category. Simpson diversity index, fish species richness and abundance assessed for the fishes of three different sampling sites of river Gomti, at Lucknow Region were found to be statistically significant (p<0.05).
