Present study was carried out to determine the larvivorous activity of fishes was found in Lower Manair Dam to
identify the potential fish species for consuming larval forms. The listed 58 larvivorous potential fish species were
collected and identified in the laboratory based on the morphometric and meristimatic characters. Pelagic feeders
occupy 25.59%, bentho pelagic feeders occupy 24.14%, demersal feeders occupy 43.10% and feeding of all
substrata occupies 05.17%. Only 22 species of larvivorous fishes are consuming mosquito larvae effectively and
contributed to 37.93% in the total population. Within the individual orders Perciformes contributed to 66.67%,
Cypiniformies contributed to 52% and Beloiniformes contributed to 50%. Most of the species have a high
larvivorous potential at early stages, hence these are the feasible in controlling reservoir larval forms. The common
name, local name, IUCN (2013.2) and CAMP (1998) conservation status of each fish was listed
