Abstract
A process and apparatus for harvesting soft shell crayfish wherein a predetermined pulsating electrical field is established in front of a moving conveyor assembly having a pulse rate which allows the tail of the crayfish to contract in synchronization with the pulse rate causing the crayfish, in most cases, to move toward and be captured by a moving trawl assembly having a conveyor assembly which transports the crayfish to an area to be sorted and stored for shipping.
