Social ProblemSpecies dying worldwide from
human industrialization
Many varieties of humandestruction
Bycatch
Crab Pot Design and IssueBendable
openings
Species cannot escape
Drowning
Law: 72 hoursDiagram of a basic crab pot
Abandoned “Ghost Pots” that could contain drowned
terrapins and other non-targeted species.
“Ghost Crab Pot” found with 94 dead
terrapins in Georgia
Derelict “Ghost” Crab Pots
BRD Team “Ghost Pot” Searches
Why New JerseyDensest populated state
Commercial & recreational crabbing◦Barnegat Bay Estuary◦Delaware Bay Estuary◦New York-New Jersey Harbor Estuary
Billion dollars◦Tourism◦Fishing◦Crabbing
Why This Species?
Bio-indicators
Proliferation of species
Species of concern
Late maturityDiamondback Terrapin (Malaclemys terrapin )
Other BycatchSpider crabs
Conches
Summer and winter flounder
Pufferfish
“...approximately 250,000 derelict “ghost” traps are added to the Gulf of Mexico each year”("National Oceanic and Atmospheric Administration")
BRD: Bycatch Reduction DevicePrevent larger
species fromentering crab pots
Easy to install
Cost-effective
Can be made to fit any size
A BRD attached to acommercial-style crab pot
Impact of BRDsLower bycatch mortality
Mandatory in Maryland on all crab pots
Scientifically proven to not decrease crab capture rates
How to Use a BRD
1. Put the BRD over the opening of the crab pot
2. Fasten with wire ties
3. Ready to use!
GoalReduce the number of species
killed from human development
Female diamondback terrapin drowned in a crab pot without BRDs in Ocean County, NJ

Public OpinionLetters of support
From local communitiesLocal Stores

Local schoolsProject Terrapin Calendar Contest
Brought awareness of the use of BRDs to children and adults
Afterschool OutreachLocal Presentations

Statistics on Crab Catch“Contrary to the substantial effect on
terrapins, BRDs had little to no effect on crab catch” (Rook et al. 2010)
Statistics on Terrapins Presence
(Rook et al. 2010)
SynopsisAnimals are drowning
BRDs can save lives
Maryland has already passed a law
Cost-effective

How to Help1. Promote the use of BRDs!
◦ The more everyone knows, the more you can help.
2. Use a BRD!◦ If you have a crab pot…use a BRD!
3. Let’s not repeat the same mistake that others have. Take a stand to
protect our local species and preserve our ecosystems!
