abstract
Water hyacinth consists of high biomass, fibrous tissue, high energy and protein content that can be used for a variety of useful applications like waste water treatment, compost and fertilizer, animal feed etc. On one hand manure and fertilizers are getting costlier day by day and on the other hand we have resources like village ponds, lakes, rivers, reservoirs, wetlands, canals, drains etc. where the much needed nutrients in the form of aquatic weeds (which otherwise pollute the water and go waste) are lying free of cost in the form of protein rich water hyacinth and make them a more suitable water resource for aquaculture. Therefore, recovering these valuable nutrient resources and recycling into some productive system like feed and compost in aquaculture makes sense both ecologically and economically. This article discusses use of water hyacinth as fish feed and compost.
