Commercial Fishing Commercial fishing remains an important Maine industry. Fishing is no longer the hazardous producer of widows and orphans as in sailing days, but today's practitioners remain salty, colorful characters. Most prized by them is the lobster, but scallops, crabs, and several fish are caught commercially. At low tide clam diggers often work the flats with their short rakes. Boat building continues on the island and Schoodic Peninsula.
Lobsters feed on snails, clams, mussels, dead fish, and other organisms.
They dart backwards powered by abdomen and tail, but they also chamber over rocks on their four pair of legs. They periodically shed and regrow the tough outer skeleton shell. Lobsters caught today usually weigh 1.5 pounds but deeper water specimens can exceed 40 pounds. Brightly-colored buoys mark the lobster traps. The individual colors are registered with the state.
