Cod fishing in the gulf of maine for recreational fishermen is closed from November 1st to the end of February. That the federal rule, and I understand that the states are also going to follow it.
You can fish for all the haddock, cusk, hake, wooffish, monkfish ect...
But it may not be a good idea to get caught with cod onboard!
Not worth loosing your boat and paying the fine !
