Stay safe & legal
Safety, rules and taking care of the fishery.
- Safety warnings
Sharp teeth — use pliers to unhook.
- Regulations
The southern New England / Mid-Atlantic stock is low, so seasons and limits are tight; the Gulf of Maine stock has its own rules. Check your state. Saltwater licenses and limits are set by each state (VMRC, NJ Fish & Wildlife, NYS DEC, CT DEEP, RI DEM, MA DMF, NH Fish & Game, Maine DMR) and by NOAA Fisheries and the Atlantic States Marine Fisheries Commission — check the current rules for your state before you keep fish.
- Conservation
Keep only what you'll eat, release the rest quickly, and follow size and bag limits.
