Aquatic invasive species threaten socio-economic and ecological systems, by invading freshwater ecosystems, and influencing their functionality and productivity, as well as disturbing key hydrological processes. Ecologically, water hyacinth can impact zooplankton and phytoplankton productivity in freshwater ecosystem, modify surface water clarity and cause hypoxia or a decrease in the concentration of related nutrients and contaminants, such as nitrogen, phosphorous and heavy metals. Field surveys and water-related reports indicate that water hyacinth (Eichhornia crassipes), which is one of the most aggressive and lethal floating aquatic weed; has invaded most water bodies in the sub tropics. Its spread is largely linked to eutrophication emanating from poor land use management practices and other environmental and climatic factors. Besides its threats and effects, its distribution in streams and rivers is not …
