Summary: 
A hydrodredge was tested using water pressure created from the hydrodynamics of the gear to lift scallops out of the seabed. The hydrodredge when compared to a more traditional dredge increased catch of surface-dwelling scallops but decreased catch of deeper-dwelling scallops. Bycatch of starfish, crabs and urchin were less likely to suffer fatal injuries in the hydrodredge.
