History of Crab Harvesting

by Crab Guy on November 5, 2008

The Chesapeake Bay, in Maryland, is where it all began. “Chesapeake” is a Susquehanock word meaning “great shellfish bay.” For centuries many people have enjoyed the bounty of blue crab, along with other delicious forms of seafood, found in the Bay.

Crab rings on the dock of Chesapeake BayNative Americans were the first to discover the bounty provided by the blue crab crustaceans in the great bay. Several European settlers stake claim to first discovering this place to catch crab. But, undoubtedly native people led European settlers to this fine place for hunting, fishing and crabbing.

Maryland Blue crabs have been caught and harvested commercially in the Chesapeake Bay area since the mid 1800s. Now, these crabs are harvested from the mid-Atlantic region (from New York to North Carolina) to Florida and several of the Gulf states, all the way to Texas. Pre-settlement blue crabs were harvested for subsistence living. There is evidence suggesting that Native Americans used spears to catch crabs in shallow water and that they may have fashioned simple traps to gig crab. During colonial times, many people survived based solely on their ability to catch crab in this region. Records show, as early as 1850, a market for soft-shelled blue crabs on the Eastern Coast of America.

Significant level of consumption fueled the demand for blue crabs in the mid-1800s. The first toothless dredge for harvesting soft-shelled crabs was patented in 1870. During this period, fishermen began using nets to harvest hard-shelled blue crab as well. In the 1870s the evolution of a commercial crabbing industry began to emerge. Railroads permitted rapid shipping of blue crab away from the coast, canning of crabmeat began and wooden boats began replacing fishing lines with scoop nets as means to catch crab. Trotlines were also developed around this time; a long line anchored at both ends with shorter lines, baited to catch crab. Trotlines remained the standard harvesting method through the 1950s and the first crab trap was patented as early as 1926.

The crabbing industry has changed as populations have changed and as the need to be more productive and efficient has risen. For crab fishermen, also known as “watermen,” the benefits of crab harvesting must always be balanced with the need to sustain the dwindling crab population, especially in the Chesapeake Bay region.

Crab harvesting has long been a part of Maryland, Chesapeake Bay and human culture. Harvesting crabs, oysters and fish supports life in the waterfront communities of the Eastern Coast shore. Many people living in these communities could tell you what time of day it is just by the coming and going of the boats in the harbor. This way of life is changing, and in many ways slipping away, due to modern conventions and the evolving bay. Yet the Chesapeake Bay in Crisfield, Maryland, where it all began, is still known as the crab capital of the world.

All About Blue Crab

by Crab Guy on October 28, 2008

Although there are thousands of species of crab, the blue crab is one of the most important and famous. Found in the Chesapeake Bay, the blue crab serves as the Bay’s signature crustacean.

The blue crab is a member of the swimming crab family, known as Callinectes (“beautiful swimmer”) sapidus (“savory.”) The species is an aggressive, bottom-dwelling predator and affects many other organisms in the Bay ecosystem and food chain.

What does the blue crab look like?
Blue crabs vary in color from olive to bluish green with white underneath.

Maryland blue crab

  • Adults have bright blue claws. Claws of mature females have red at the tips.
  • Rear swimming legs shaped like paddles and three pairs of walking legs.
  • The width of the shell is more than twice its length and blue crabs can grow to 9 inches wide.
  • The shell has nine teeth on the margin; the ninth tooth is a strong spine.
  • Male blue crabs’ abdomens, also known as the apron, is strongly tapered, resembling an inverted “T.” The female abdomen is broad and rounded, wile the immature (prior to mating) female’s is triangular.

Where does the blue crab live?
During the course of their lives, blue crabs utilize all habitats within the Bay. Distribution of crabs varies with age, sex and season.

  • They tend to be most abundant in shallower areas during warm weather and are plentiful in the Bay’s deeper portions during winter.
  • Females congregate in saltier waters, but males range much farther up the Bay and tributaries.
  • They are bottom-dwellers, using bay grass beds for mating, shelter and nursery habitat. This is also where they find food.

What does the blue crab eat?
Blue crabs serve as both predator and prey, for fish, birds and even other blue crabs. Soft shell crabs, blue crabs that have recently molted, are especially vulnerable to predators.
Blue crabs are omnivores and feed on nearly anything they can find, including:

  • Clams and oysters
  • Crustaceans
  • Dead fish
  • Bristle worms
  • Juvenile and soft shell blue crabs

Other facts about the blue crab:

  • Few blue crabs live longer than three years.
  • Mature female crabs are known as “sooks” and males are called “jimmies.”
  • Blue crab mating takes place from May through October.

A Guide to the Many Different Types of Crab

by Crab Guy on October 28, 2008

There are over 4,400 varieties of crab. Here is a guide to a few of the most common, edible types of crab:

Blue Crab

Maryland blue crabIts Latin name, Calinectes sapidus, means “beautiful swimmer” and “savory.” Blue crabs are indeed a beautiful blue-green color, with large, bright blue claws. The blue crab is the most prolific species on the East Coast of the United States, particularly in the Chesapeake Bay in Maryland, where it is the Bay’s signature crustacean. Blue crabs also give us the soft shell crab, which is a blue crab directly after the molting process. Blue crabs range in size from 3 ½” to over 9” and do turn the traditional reddish color when cooked.

Dungeness Crab

Latin name, Cancer magister, this crab is found in coastal waters from Alaska to Baja, Mexico. Dungeness is a large crab, usually weighing from 1 and ¾ to 4 pounds, and brown to purple in color. The Dungeness crab is named for the former small town Dungeness on the Olympic Peninsula in Washington state, which first began commercially harvesting the delicacy. The pink flesh of these crabs is succulent and sweet, making it an ultimate, desirable catch. Law requires the crab to be at least 6 and ¼” long to be harvested and only male crabs can be taken from the waters. Prime season for Dungeness crab is in the winter months.

Horseshoe CrabHorseshoe crab

This crab is named for its resemblance in shape to a horseshoe. Horseshoe crabs are considered living fossils, tracing roots back some 500 million years. It is found along the Atlantic Coast from Nova Scotia to the Yucatan and along Asian coasts from japan and the Phillipines to India. This crab is edible, however, the ratio of meat to shell is fairly small.

King Crab

This giant crab is often called, “Alaskan King crab,” “Japanese crab,” and “Russian crab” due to its size, which can reach up to 25 pounds and measure up to 10 feet. King crab has been made recently famous on the popular television show, Deadliest Catch. These crabs are large, but only about one quarter of the entire crab is edible, primarily the legs and claws. Only male King crabs are harvested. The delicately-flavored meat is bright, snow white with a bright red outer edge.

Rock Crab

Rock crab is found on the East Coast of the United States, living among rocks and in deep water. Rock crabs’ spindly legs make it resemble a spider and is also known as “Spider crab.”
