Ichthyo fauna and hydrophyte floral diversity in the Lower Manair Dam at Karimnagar district, (Telangana State) India

Abstract

Fish and Hydrophytes bio diversity in the Lower Manair Dam was studied from November-2014 to October-2015. Fish samples were collected once in every fortnight with help of local fishermen by using fishing Craft and Gear. A total of 66 species of fishes belonging to 9 orders such as Cypriniformes (27 species), Siluriformes (13species), Perciformes (15 species), Channiformes (4 species), Beloniformes (2 species), Anguilliformes (2 species), Osteoglossiformes (one species), Cyprinodontiformes (One species) and Mugiliformes (one species). The number and percentage composition of population status were calculated to 32.81% common, 29.69% abundant, 21.86% moderate, and 15.63% rare species were identified in the Lower Manair Dam. Of these, 52 species of fish were least concerned (LC), 5 were data deficient (DD), 3 were near threaten (NT), 3 were not evaluate (NE), 2 species of fish were endangered (ED) and 1 species of fish was vulnerable (VU). Forty eight different species of aquatic macrophytes were recorded in 04 classes, 20 orders and 26 families, which include five free floating macrophytes, ten submerged, and thirty three emergent species of weds were recorded. The percentage composition of class, order and families were calculated during the period. IUCN (2015.4), CAMP (1998) status and Shannon-Weiner diversity (H-), Evenness (E), Hmax = ln(S), Maximum diversity possible and species richness (S) for different months were calculated.
