Abstract

A mechanical oyster harvester was designed, constructed and tested in Chesapeake Bay,Va.,from 1972 to 1976. It couples the escalator system of a conventional Maryland soft clam dredge with a newly designed head. Revolving spring-loaded teeth attached to two drums in the head pull or rake oysters from the bottom and horizontal water jets and the action of the revolving teeth impel the oysters onto a conveyor belt which carries the oysters to the boat.
