Water hyacinth has also been used indirectly to feed fish. The physical method is employed by directly harvesting, cutting, and removing the plant using machines or manual removing by hands and hand tools. The result is a significant decrease in turbidity due to the removal of flocs and also slight reduction in organic matter in the water. Water hyacinth is an ingredient in Taiwanese and Javanese cooking. When aggregated together with other environmental and social benefits, however, the systems have the potential to provide sustainable economic and environmental returns. Water hyacinth has also been used for the removal or reduction of nutrients, heavy metals, organic compounds and pathogens from water (Gopal 1987). 2500 and 540 t yr−1 of N and P, respectively, can be recycled from waterways. To eradicate or control water hyacinth, physical, chemical, and biological methods are widely applied throughout the world. The inflorescence bears 6 - 10 lily-like flowers, each 4 - 7cm in diameter. Microbial decomposition breaks down the fats, lipids, proteins, sugars and starches. Progress on water hyacinth (Eichhornia crassipes) management - Maricela Martínez Jiménez. Researchers are trying to find economic use so that these problem plants become a resource for income generation. In the last 10 years the rapid spread of the plant in many parts of Africa has led to great concern. As Hyacinth is toxic, its leaf, sap and bulbs cause alleregic reactions.The hyacinth bean or hyacinth bataw, on the other hand, is a vine which has heart-shaped leaves.
