Maryland has acted to protect Diamondback Terrapins. Effective July 1, 2007, it is unlawful to take or possess them for commercial purposes (Chapters 117 & 118, Acts of 2007; Code Natural Resources Article, sec. 4-902).
Terrapin are sexually dimorphic, with females much larger than males. Males range between 4 and 5 inches, while females average nearly 7 inches. The largest terrapin on record was a female measuring 9 inches. This disparity continues in the time needed to reach maturity as well. Males reach maturity at 3 years old, while females are not full grown until age 7. A long lived species, the diamondback terrapin can reach ages in excess of 20 years. Carnivores, their diet includes mollusks, insects, crustaceans, and small fish.
Chesapeake colonists ate terrapin prepared Native-American fashion, roasted whole in live coals. Abundant and easy to catch, terrapin were so ample that landowners often fed their slaves and indentured servants a staple diet of terrapin meat. Later, in the 19th century, the turtle was appreciated as gourmet food, especially in a stew laced with cream and sherry. Subsequently, tremendous retail demand and heavy fishing of the terrapin nearly depleted its supply, and protective laws were enacted.
In 1891, some 89,000 lbs. of terrapin were harvested from Maryland waters. With few exceptions, annual harvests since 1956 have remained below 11,000 lbs.
The Department of Natural Resources is responsible for the rules and regulations governing the conservation of diamondback terrapin (Code Natural Resources Article, sec. 4-903).
Detailed information about the turtle's biology and living habits can be found at the website of the National Aquarium in Baltimore.
