Abstract

A shrimp trawl or net having a second piggyback net attached to an opening in the top side of the body of the trawl and a pulses to stimulate mature shrimp to enter the opening in the second net. Alternatively, an upper deck is formed in the body of the main trawl and the pulses is positioned so as to stimulate the targeted shrimp species to enter the upper deck while non-targeted species and debris pass out the back of the trawl. Both the piggyback net and the upper deck have a releasably closable back end to allow the operator to close the net or deck during towing operations, and to open the back end after the trawl has been pulled aboard the shrimp boat.
