Abstract: The mandatory use of the Nordmøre Grid in the Gulf of Maine pink shrimp fishery since early 1990s has greatly reduced finfish bycatch. However, the Nordmøre grid cannot reduce small fish and small shrimps that pass through the 25 mm grid spacing. As a result, small fish are still being caught and discarded. Capture and landing of small shrimps wastes resources without added to the landed value. This presentation will review recent advances in conservation engineering research to reduce finfish bycatch and small shrimps in the Gulf of Maine pink shrimp fishery. The devices tested include a duel grid system for reducing small shrimps, a rope grid for reducing finfish, and a topless trawl for reducing pelagic species.
