Abstract
Infestation of microalgae and macrophytes in aquatic ecosystems is posing serious challenges to their ecological functioning and aquaculture use. Various studies indicate that fishes can be effectively used for the control of microalgae and macrophytes weeds in aquatic ecosystems such as aquaculture ponds, tanks, reservoirs, irrigation canals etc. Accordingly, this article reviews the promising candidate fish species which can act as bio-control agents for excessive algal and weed growth, such as silver carp, common carp, grass carp, tilapia, barbs, giant gourami and mahseers. It also covers the experimental studies carried out using these species in different ecosystems and discusses their potential as well as constraints.
