Summary:

A trap modification reduced bycatch of diamondback terrapins (Malaclemys terrapin) in a blue crab (Callinectes sepidus) pot fishery in the Patuxent River, a tributary of the Chesapeake Bay. Three wire modifications were tested and found that terrapin bycatch can be reduced without decreasing the number or size of captured crabs.
