Abstract

A harvesting device particularly suited for harvesting artemia cysts. The invention in its various embodiments comprises a frame and a net coupled to the frame. The frame can include a front support frame, a rear support frame and a sledding frame. A net having a first end and a second end can be secured to the front and rear support frames respectively. In certain embodiments, the net has an aspect ratio or 4:1. One or more skids can be coupled to the frame. In certain embodiments, the skids are coupled to the sledding frame. In yet other embodiments, the skids are coupled to the sledding frame at substantially the joining of the front support frame and the sledding frame. The second end of the net can be attached to a conduit in communication with a harvest vessel by a coupling. The harvest vessel can include one or more dewatering stations in communication with the conduit.
