Next Generation Scallop Dredge Design

We propose to design and test a scallop dredge frame that will be lighter, structurally stronger, and designed to reduce the capture and retention of sea turtles, skates and flatfish species. This project is a continuation of efforts started in 1994 that have successfully decreased the bycatch of the identified species. The new dredge will incorporate improvements to the design changes currently being tested on reducing sea turtle injury and mortality. We will work on optimizing the design for groundfish bycatch reduction using more appropriate materials and cross-sections. The project will utilize tow tank testing for cutting bar hydrodynamics and computer modeling for frame component design. Besides reducing bycatch, the new dredge will catch more scallops, reduce energy consumptions, and must hold up to the rigors of fishing.
