The potential for further proliferation of water hyacinth in lakes Victoria and Kyoga and some urgent aspects for research

Abstract

Shore environments of lakes victoria and Kyoga with apotential for the establishment and proliferation of waterI hyacinth have been identified. They are characterised by :(i) shelter from violent off-shore and along-the-shore wind and wave action (ii) flat or gentle slope under relatively shallow water, and (iii) a muddy bottom rich in organic matter. Such environments are strongly associated with emergent macrophytes of papyrus, vossia and, at times, Typha while Nile lettuce, Ceratophyllum, Mylliophylum ahd Nymphaea commonly occur there Urgent research on water hyacinth is proposed in the areas of nutrient relations, weed biology and on its impact on the biodiversity resource, with particular reference to the fishery component . Findings from the research could facilitate formulation of weed control options and alternative resource management strategies. A regional approach to resolve the water I hyacinth menace is highly recommended.
