Season

All year

• Federal (EEZ) regulation published by NOAA Fisheries GARFO; Massachusetts state-waters rules may differ.
• Whole fish (17 inches) or tails (11 inches) may be landed. Fish or parts of fish, with the exception of cheeks and livers, must have skin on while possessed on board a vessel and at the time of landing in order to meet minimum size requirements. "Skin on" means the entire portion of the skin normally attached to the portion of the fish or fish parts possessed. Monkfish tails are measured from the anterior portion of the fourth cephalic dorsal spine to the end of the caudal fin. Any tissue anterior to the fourth dorsal spine is ignored. If the fourth dorsal spine or the tail is not intact, the minimum size is measured between the most anterior vertebra and the most posterior portion of the tail.
