Summary: 
Crab traps were fitted with a Turtle Excluder device to reduce the incidental capture of diamondback terrapins. No diamondback terrapins were caught during this study but the total catch rate of targeted blue crabs, compared to the standard traps, increased by 25.7% (14.5% sublegal size, 32.9% legal size). The difference in total catch rates and catch rates of legal sized blue crabs between the two traps were significantly different.
