A license holder must not fish at night or on Sundays during the summer season. Specifically, he must not fish from 1/2 hour after sunset to 1/2 hour before sunrise each day or from 4:00 p.m. Saturday to 1/2 hour before sunrise on the following Monday morning.

A legal lobster is between 3 8/32 inches and 5 inches long from the bottom of the eye socket to the rear end of the body shell. Lobsters not within these measurements should immediately be thrown back into the water alive. Release these lobsters to avoid a $50 violation fee plus $25 for each of the first five illegal lobsters and $50 for each additional lobster.
It's also illegal to take lobsters that have eggs under the tail or are marked with a V-notch on the right flipper, signifying that the lobster is female. If the lobster is damaged so that you can't to tell whether or not it has been V-notched, it's illegal to take the lobster. Return egg-bearing or V-notched lobsters alive to the water immediately to avoid a $50 violation fee plus $100 for each illegal lobster.
All lobster traps must have both escape vents and a biodegradable escape panel.
Buoys lines must be less than 7/17 inch in diameter and either attached to the buoy line with a weak link or made of sinking/neutrally buoyant line.
