  • Patent number: 5811007
    Abstract: A vascular plant aquaculture system and method are provided that include a water hyacinth enclosure for bioremediating wastewater and producing plant biomass for animal feed. A road and a flume are disposed about the water hyacinth enclosure for permitting access to the plants by a harvester, which is adapted to lift plants from the enclosure and deliver them to the flume, which carries purified water and the harvested plants for further processing. Such further processing may include chopping and vermicomposting.
