Ano: 2009 URL: http://hdl.handle.net/1834/4076 Macrophytes of Lake Victoria and succession after invasion of Water Hyacinth OceanDocs Omondi, R.; Kusewa, Mwende. The distribution of Lake Victoria (Kenya) macrophytes is described. Succession of macrophytes in the lake became more dramatic and dynamic after invasion of water hyacinth. The weed pushes and smothers other free-floating macrophytes like Pistia stratiotes. It then provides substrates for the emergent Vossia cuspidata, which later reduces its population by competition for light and nutrients. The noxious weed is believed to have led to extinction of Azolla nilotica in the lake.

Ano: 2006 URL: http://hdl.handle.net/1834/1496 The effect of water Hyacinth, Eichhornia Crassipes, infestation on phytoplankton productivity in Lake Naivasha and the status of control OceanDocs Mironga, John Momanyi. The paper presents data collected in an assessment of effects of water hyacinth infestation on phytoplankton productivity in Lake Naivasha, Kenya. A summary of the status of control and strategies for the future is given. The ecological effects of water hyacinth, Eichhornia Crassipes, on Lake Naivasha have received little attention compared to the large body of work available on the weed’s socioeconomic impact on the country’s water ways and methods for its removal. This study was conducted to determine if water hyacinth infestation in Lake Naivasha affects phytoplankton productivity. Several sampling stations were set up in the lake at sites where the floating mats of the weed were present and sites where the weed was absent. Phytoplankton chlorophyll-a...
