Brought to you by:

New Hampshire has an active commercial marine fishing industry. Commercial finfish harvesting occurs almost exclusively in federal waters. State licenses may be required to harvest, transport, sell, or possess.

Reporting Requirements: Any person holding a permit to net or harvest from coastal waters must submit a monthly report of fishing activities. Forms are available from Fish and Game Marine Division. Fishermen must also participate in the National Marine Fisheries Service Vessel Trip Report program, if they have a federal permit for specific species.

Groundfish: See tables below for specific information and Definitions for a list of groundfish species.
No mobile gear may be used to take finfish or crustaceans in state waters.
Minimum mesh size for gillnets and mobile gear is 6.5 inches to take, transport or possess groundfish.
All federally permitted vessels must abide by current federal trip limits for groundfish.
