social problem
Social Problem
  • Species dying worldwide from

human industrialization

  • Many varieties of human

destruction

  • Bycatch
crab pot design and issue
Crab Pot Design and Issue
  • Bendable openings
  • Species cannot escape
  • Drowning
  • Law: 72 hours

Diagram of a basic crab pot

derelict ghost crab pots
Derelict “Ghost” Crab Pots

Abandoned “Ghost Pots” that could contain drowned terrapins and other non-targeted species.

“Ghost Crab Pot” found with 94 dead terrapins in Georgia

why new jersey
Why New Jersey
  • Densest 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
Why This Species?
  • Bio-indicators
  • Proliferation of species
  • Species of concern
  • Late maturity

Diamondback Terrapin (Malaclemys terrapin )

other bycatch
Other Bycatch
  • 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")

Spider crabs

Conches

brd bycatch reduction device
BRD: Bycatch Reduction Device
  • Prevent larger

species from

entering crab pots

  • Easy to install
  • Cost-effective
  • Can be made to fit any size

A BRD attached to acommercial-style crab pot

impact of brds
Impact of BRDs

Lower bycatch mortality

Mandatory in Maryland on all crab pots

Scientifically proven to not decrease crab capture rates

how to use a brd
How to Use a BRD
  • Put the BRD over the opening of the crab pot
  • Fasten with wire ties
  • Ready to use!
slide12
Goal
  • Reduce the number of species killed from human development

Female diamondback terrapin drowned in a crab pot without BRDs in Ocean County, NJ

  • Local Stores
    • L & H Woods and Water
    • Lacey Marine
  • Local schools

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

how to help
How to Help

1. 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!
