The study offers management guidelines for control and management of water hyacinth in Nigeria. damage of cultivated crops by water hyacinth in West Bengal, India amounted to $24 million in one year (Baruah and Singh, 1984). Lagos State Waterways Authority (LASWA) intensifies effort on water hyacinth clearing exercise. Reproduction of hyacint h is very high and fast so it is considered a weed that can damage the aquatic environment. It causes damage to boat engines and obstruct free flow of traffic on the Waterways. Despite water hyacinth’s ability to survive in wide ranges of sunlight, pH, and water supply (Tag El Seed 1975), elevated levels of salinity inhibit its health and vitality.

Water hyacinth is able to grow in a wide variety of water bodies from lakes, streams, ponds, waterways, ditches, and backwater areas, although it prefers, and grows most prolifically, in nutrient-enriched waters. As these plants can make the water oxygen-deprived, other aquatic plants and animals living in that water body will eventually get eradicated.
