The development of a derelict crab trap removal incentive program for commercial shrimpers

Abstract

Due to fishery-tailored gear, shrimpers are often affected by benthic marine debris, specifically derelict crab traps. To alleviate the impacts on the commercial shrimping industry in the Mississippi Sound, a team of natural resource professionals and stakeholders developed a derelict crab trap removal incentive program for commercial shrimpers. In three years, this program led to the removal of 2904 derelict crab traps from the north-central Gulf of Mexico at a total average cost of $35,595 per year to implement the program, or $53 per derelict crab trap. Results from this study showed the cost of the program could further be reduced while covering the same shrimping area, through the inclusion of fewer disposal locations and targeting active and engaged shrimpers. This program led to the removal of crab traps by non-registered shrimpers, indicating that the existence of the program and associated outreach could lead to improved environmental stewardship without an incentive.
