Blue Crab


Blue crabs are agile swimmers and usually swim sideways, sometimes backwards and forward. The paddle shaped fifth pair of legs rotate like propellers for swimming. They have long pinchers to catch fast moving prey. They cannot survive for long periods out of the water.

They stay buried under sand or mud most of the time, particularly during the daytime and winter. They come out to feed during high tide on various organisms. Blue crabs are harvested with traps, nets and dredges and, are found in brackish estuaries and bays.

For hard-shell crabs the larger, meatier males, called “jimmies”, are more desirable. The apron, the shape on the belly, of a male is T-shaped. One a young female (or she-crab), the apron is triangular and a mature female crab (or sook) has a semicircular apron. Soft shell are separated by size, not sex, with the largest called whales, then jumbos and then primes.

Fresh-picked blue crab is sold in America in 1 pound plastic containers and kept on ice. Canned pasteurized crabmeat is common in retail markets but less desirable because the meat tends to be stringy.

Did You Know?
Pregnant blue crabs carry their eggs in a sponge-like protrusion; to conserve the blue crab population and ensure their future, harvesting crabs with this protrusion visible is illegal.

Over its 2- to 3-year life span, a blue crab outgrows and sheds its shell about 20 times. Once the crab has molted, the new shell takes about 4 days to harden. Just after shedding, the crab’s shell is soft enough to eat.
