Today, because of habitat loss, boat strikes,
and other human-induced stresses, terrapin
populations within the Chesapeake Bay are
under even greater pressure to survive.
The greatest threat to diamondback terrapins
is drowning in crab pots. Male and young
pots, as they
attracted to the same bait used to attract blue
crabs. Terrapins may also enter out of
curiosity or because they are looking for a
safe resting place.
Recreational crab pots are typically set in the
same places males and juvenile female
terrapins live - shallow, near-shore waters
along creeks and marshes.
The blue crab
sapidus, is one of
the largest on-
in the Chesapeake
Bay, and crabbing is a favorite pastime for many
Virginia residents as well.
In Virginia, it is illegal to collect
diamondback terrapins for commercial or

A bycatch reduction device (BRD) is a simple
and low-cost way to prevent terrapins and other
marine organisms, such as blue catfish which eat
blue crabs, from getting into your crab pots.
Attaching a BRD to each funnel opening will
prevent most terrapins and other unwanted
organisms from entering the pot.
Studies have shown that while effective at
preventing other animals from entering,
BRDs have little impact on the size and
number of blue crabs found in crab pots.
