Abstract: Aquatic macrophytes are basically seen as those plants that complete their life cycle in water and cause harm to the aquatic environment. The attention of fishery managers is always towards the eradication of aquatic macrophytes. This study is therefore timely as it reflects on the economic importance of aquatic macrophytes in aquatic ecosystem and therefore recommends a study on the utility value of aquatic macrophytes of ecological importance. The monitoring of colonized rivers and large water bodies by aquatic plant is necessary for proper management and development of colonization model is hereby advocated.
