Water hyacinth {Eichhornia crassipes) in Lake Limboto was covering the area about 40 to 60% in 2008. It caused a lot of problems on water transportation, fishing activities, reducing water quantity and quality. To manage the number of water hyacinth population, biological control use omnivorous species and such as grasss carp (Ctenopharingodon idella) is a promosing alternative. In this study, effect of different stocking density of grass carp on the population of water hyacinth was observed.
