Identification and Retrieval of Derelict Crab Pots to Reduce Bycatch in Barnegat Bay
The NOAA Marine Debris Program partnered with the Conserve Wildlife Foundation of New Jersey to remove over a thousand derelict crab pots from Barnegat Bay, New Jersey. Together, they also conducted an assessment to identify derelict pots in the bay, determine the percentage of pots that are lost annually, and inventory bycatch caught in retrieved pots.
Type of Project: Community-based Marine Debris Removal Grant
Project Dates: September 2015 - September 2017
Who is involved?
The Conserve Wildlife Foundation of New Jersey (CWF) removed over 1,000 crab pots from Barnegat Bay, NJ with the support of a NOAA Marine Debris Program Community-based Marine Debris Removal Grant. CWF collaborated with Stockton University, Monmouth University, ReClam the Bay, the Marine Academy of Technology and Environmental Science (MATES; a vocational technical high school), the New Jersey Corporate Wetlands Restoration Partnership, and the fishing community to identify, retrieve, and inventory derelict crab pots. CWF used the Fishing for Energy program for waste to energy disposal of retrieved gear through a match provided by Covanta. This project also focused on education and outreach efforts, in part through partnership with the WeCrab project led by Rutgers University and supported by a NOAA Marine Debris Program Marine Debris Prevention through Education and Outreach Grant.
What is the project and why is it important?
An estimated 10% of all recreational and commercial crab pots are lost or abandoned in Barnegat Bay each year due to various reasons, including from storms and from passing boats accidentally cutting lines. These derelict crab pots can damage sensitive habitats, create navigational hazards, and continue to trap and kill various marine species including harvestable crabs (a phenomenon called ghost fishing), resulting in lost catch opportunities and financial losses for fishermen. This project not only worked to remove these derelict pots, but also to better understand how many pots are lost in Barnegat Bay and what their impacts are.
The project partners identified and removed crab pots during two annual closed seasons for blue crab, typically December to March. Monmouth University and MATES developed an inventory of all retrieved derelict pots during this time, which includes photographs of the pots, descriptions of all bycatch, and if pots include Terrapin Bycatch Reduction Devices (BRDs). The project also surveyed the commercial and recreational fishing community to gather information on the percentage of pots lost annually and to help develop a long-term reporting system for lost pots. All salvageable pots retrieved by the project were returned to their owners or made available to local crabbers, while non-salvageable pots were broken down and disposed of at the Barnegat Bay Fishing for Energy collection bin.
In addition to removal efforts, this project conducted education and outreach activities focusing on the impacts of derelict crab pots. Print materials and decals were developed with messaging on the impacts of marine debris and specifically derelict crab pots. In addition, the project provided informational presentations for the community and local schools. A lesson plan was developed to use at MATES and in the “Terrapin Education KIT modules,” which was used by educators across the East and Gulf Coasts. The project also collaborated with the WeCrab project led by Rutgers University to expand on its education and outreach efforts.
