Fish that are predatorsrnof the immature stages of mosquitoes are
referred to as larvivorous
fish. Amongrnall the biological control agents, larvivorous
fish are most common and widelyrnused in vector control management. A survey was conducted in Lake Kolleru withrnan objective to document the larvivorous
fish fauna available in the lake whichrnrevealed the occurrence of 29 species of larvivorous
fish from 6 orders, 14rnfamilies and 20 genera. Order mugiliformes
was the most dominant group with 9rnspecies and cyprinidae
was the dominant family with 8 species. According to thernIUCN (2015) red list of threatened species, 89.65% of species are at leastrnconcern, 3.44% are at near threatened, 3.44% are not assessed
and for 3.44% ofrnspecies data is deficient. As per the CAMP report (1998), 10 species are atrnlower risk near threatened, 1 at lower risk least concern, 5 are vulnerable, 12rnare not evaluated and for 1 species data is deficient. Out of 29 larvivorous
rnfish, 14 species are very common, 11 are abundant in the lake and 24 varietiesrnof fishes are food fishes of which 14 species are cultivable. 23 species arernfrom both freshwater and brackish water regions and the rest from
freshwaterrnregion only. Several anthropogenic activities including pollution, habitatrnloss, human interference, over exploitation and siltation
are causingrnbiodiversity loss and seriously affecting the lake resources. The indigenousrnlarvivorous
fish species of the lake can be successfully used for integratedrnvector control management.
