Explainer

An angler moving from freshwater to the coast meets an entirely separate regulatory structure, and the assumptions do not transfer.

A different licence

Saltwater fishing generally requires its own licence or registration, separate from the freshwater one, and holding a freshwater licence gives you nothing on the coast.

Several states also administer a federal saltwater angler registry through their own licensing, which is why registering with the state may satisfy the national requirement.

Shore, pier and charter fishing all have their own treatment. Some piers hold a blanket licence covering anglers on them; some charters cover their passengers.

Who sets the rules

State agencies manage nearshore waters, typically out to three nautical miles on the Atlantic and Pacific and nine in parts of the Gulf.

Beyond that, federal management applies through the regional fishery management councils, under the Magnuson-Stevens Act.

The consequence is that the same species can carry different size limits, bag limits and seasons depending on how far from shore it was caught — and the burden of knowing which applies is on the angler.

Seasons that close in-season

Federal seasons for species like red snapper and grouper are set by quota, and they close when the quota is projected to be reached — sometimes with short notice.

That is unlike most freshwater seasons, which are fixed on a calendar. Checking before a trip is not optional.

Gear that is required

Descending devices and venting tools are required for reef fish in several federal fisheries, to address barotrauma in released fish brought up from depth.

Circle hooks are mandated in a number of bait fisheries, for the reasons covered in our piece on hook regulations.

Turtle-release gear is required in some fisheries, and highly migratory species permits are required to fish for tuna, sharks and billfish.

Reporting

Several states now require electronic reporting of landings for certain species — a trip declaration before departure, a landing report after. Failing to file is the violation, not just fishing without permission.
