Maine lobster

The American lobster inhabits the continental shelf from Labrador to North Carolina, with the highest densities in the Gulf of Maine and Georges Bank. It prefers rocky, cold waters (4–18°C) and shelters in crevices. Lobsters are decapods with ten legs, the first pair modified into large claws—one crusher, one pincher. They molt periodically to grow, and females can carry up to 100,000 eggs under their tails. Juveniles are pelagic for a few weeks before settling to the bottom. The species is long-lived, with some individuals exceeding 50 years.

Maine's lobster fishery is one of the most valuable in the U.S., landing over 100 million pounds annually in recent years. It is managed through strict regulations: minimum and maximum size limits, protection of egg-bearing females (V-notching), and a limited entry license system. The fishery is trap-based, reducing bycatch and habitat damage. Management has been credited with sustaining the population despite heavy fishing pressure. However, warming waters and shifting predator ranges pose emerging challenges.

Maine lobster is prized for its sweet, tender meat, served boiled, steamed, or in rolls, bisques, and other dishes. The industry supports thousands of lobstermen and related businesses, from bait suppliers to processors. Live lobsters are shipped worldwide, and processed meat is a major export. The iconic lobster roll—a sandwich of lobster meat with mayonnaise or butter—has become a cultural symbol of New England. Tourism also thrives on lobster-related experiences, from wharf-side dining to lobster boat tours.

Beyond the familiar red shell, lobsters can be blue, yellow, or even albino due to genetic mutations—rare but documented. The largest recorded American lobster weighed over 44 pounds and was caught off Nova Scotia. Lobsters were once so abundant that they were used as fertilizer and fed to prisoners, a stark contrast to their current luxury status. The V-notch program, initiated in the 1940s, is a pioneering example of fisher-led conservation. Also, lobster blood is colorless until exposed to oxygen, then turns blue due to hemocyanin. Climate change is shifting the species' range northward, with southern New England waters becoming too warm.

V-notch

A notch cut into the tail of an egg-bearing female lobster to mark her as protected; it is illegal to harvest her.

Molting

The process of shedding the exoskeleton to grow, during which lobsters are soft and vulnerable.

Crusher claw

The larger, blunt claw used to break shells; the other claw is the pincher, used for tearing.
