Abstract:
Fish faunal diversity in the four larger freshwater tanks at Jammikunta mandal was studied from October-2016 to September-2017. A total of 56 species of fishes belonging to 9 orders such as Cypriniformes (27 species) Siluriformes (13species), Perciformes (14 species), Channiformes (4 species) Beloniformes(2 species), Angulliformes (2 species) Osteoglossiformes (one species) and Mogiliformes(one species). The number and percentage composition of population status was calculated to 32.81% common, 29.69% abundant, 21.86% moderate, and 15.63% rare species were identified in the freshwater tanks. According to IUCN (2017-2) status 82.14% species are least concerned (LC), 3.57% are data deficient (DD), not evaluate (NE) and endangered (EN), and 1.78% species of fish is vulnerable (VU). CAMP (1998) status revealed that 35.71% not evaluate (NE) and Lower risk near threatened(LRnt), 14.29% vulnerable (VU), 8.93% data deficient (DD), 3.57% endangered (EN), 1.78% Lower risk least concern (LRlc).
