scientific name of the blue crab is Callinectes sapidus, which comes
from the Greek word for beautiful swimmer and the Latin word for
tasty. Blue crab originated in the western Atlantic from Nova Scotia
to Uruguay, and were introduced into the waters off the coasts of
Europe in the Atlantic, Baltic and Mediterranean Seas first in the
ballast of ships and later intentionally. It is a decapod crustacean,
with ten legs, the front two of which have mutated into claws and
the back two into paddle-like appendages to help with swimming.
Blue crabs prefer to eat things that are already dead, but are very
aggressive and will go after anything they think they can catch.
Fisheries for blue crab on the Atlantic Seaboard of the United States
are centuries old and have recorded booms and busts as a result
of oceanographic fluctuation, disease, and local overfishing. Crabs
are taken with baited pots, tangle nets, hand dip nets, and crab
rings, and fisheries are now regulated by state and federal agencies.
