ABSTRACT:
Apparatus for harvesting aquatic plants from a body of water includes transporting means, such as a trailer or a floating craft, adapted to move into the body of water. A centrifugal pump mounted on one end of the transported is adapted to be at least partially submerged in the body of water, the pump including a housing having an opening for transmitting water and aquatic plants therein into the housing. The centrifugal pump pumps water and the aquatic plants from the body of water. An envelope surrounds at least a portion of the opening in the housing and extends outward from the housing and the opening for restricting water flow into the opening.
