Saturday morning at the boat ramp: trailers lined up, someone fumbling with a drain plug, and a game warden walking the dock asking to see licenses and checking a cooler of crappie against the daily limit. Fishing doesn’t have referees, but it has plenty of rules, and they’re there so there are still fish to catch next year. This page covers the fishing regulations every angler deals with: licenses, catch limits, size limits and seasons, how to release fish so they live, the boating rules that apply to anglers, and the unwritten etiquette of sharing the water.

One big caveat first: fishing rules are set state by state, water by water and species by species, and they change every year. We explain how the system works; your state fish and wildlife agency’s current regulations are the final word.

Fishing licenses: who needs one

States require most adult anglers to carry a fishing license, sold by the state fish and wildlife agency online, through its app, and at tackle shops and sporting goods stores. The age where you need one is set by each state; in many states, including California, Colorado and New York, it’s 16. Kids under that age usually fish free. There are separate or combined licenses for freshwater and saltwater in many coastal states, plus extra stamps or permits for some species (trout and salmon are common examples), and short-term licenses for visitors.

  • Free fishing days: many states set one or more days or weekends a year when anyone can fish without a license (other rules still apply). Maine’s 2026 free days, for example, were February 14 to 15 and May 30 to 31.
  • Out of state: you need a license from the state where you fish, usually a nonresident one.
  • Carry it: keep your license (or the app version) on you while fishing; wardens can ask for it.

Saltwater and federal waters

In the ocean, states manage the water near shore and NOAA Fisheries manages federal waters farther out. NOAA explains that federal waters usually begin three miles from shore, but nine miles off Texas, Puerto Rico and Florida’s west coast. Anglers in federal waters, or fishing for anadromous fish such as salmon, striped bass and shad, need to be in the National Saltwater Angler Registry; in 22 of the 24 coastal states, your state saltwater license or registration covers that for you. Federal waters also have their own seasons and gear rules. For example, under the DESCEND Act, anyone fishing for reef fish in Gulf federal waters must have a descending device or venting tool rigged and ready.

Catch limits, size limits and seasons

The U.S. Fish and Wildlife Service’s advice to beginners is to pick up your state’s fishing regulations, which tell you the kinds of fish, the minimum size limit and how many you can catch in a day. Here’s what the terms mean:

RuleWhat it means
Daily bag (creel) limitHow many of a species you may keep per day. Some states also have a possession limit for fish already in your freezer or cooler.
Minimum sizeA fish shorter than this must go back. Measure from the tip of the snout to the tail as your state describes.
Slot limitYou may keep fish only within (or only outside) a size range, protecting the best spawners.
Seasons and closuresDates when a species may be kept, fished at all, or only released, often around spawning.
Gear and bait rulesRules such as single barbless hooks or artificial lures only on some trout streams, circle hooks for certain saltwater bait fishing, or limits on the number of rods.
Special watersIndividual lakes and rivers often have their own limits that override the statewide ones.

Most state agencies publish an annual regulations booklet and a free app with rules by lake. Check before every trip, and especially before you keep a fish.

Catch-and-release best practices

Releasing a fish only helps if it survives. NOAA Fisheries’ catch-and-release best practices boil down to a few habits:

  • Use the right hooks: circle hooks, barbless hooks or hooks with the barb crimped down make release easier and raise survival. Circle hooks are much less likely to be swallowed.
  • Don’t play fish to exhaustion, and never gaff a fish you plan to release.
  • Keep it in the water and unhook it there when you can. If you lift it out, less than 60 seconds in the air is ideal.
  • Wet hands, gentle grip: handle the fish as little as possible and only with wet hands, avoid the eyes and gills, and support big fish along the length of the body. A soft knotless or rubber net helps.
  • Swallowed hook? Cut the line as close to the hook as you can rather than digging for it.
  • Revive it: hold the fish facing into gentle current or move it slowly head-first through the water until it swims off on its own.

Good pliers make fast, in-water release easy. The Piscifun aluminum saltwater pliers (about $23) have a hook-removing nose, split ring tips and tungsten carbide cutters for braid.

Fish from deep water: barotrauma

Fish pulled up quickly from deep water can suffer barotrauma: gas expands inside them, and you may see bulging eyes, a stomach pushed out of the mouth or a bloated belly. They often can’t swim back down. NOAA Fisheries calls descending devices, weighted tools that lower the fish back to depth before letting it go, the preferred way to release reef fish, and they’re required in some federal waters. Deep-water walleye, lake trout and other freshwater fish can be affected too; follow your state’s advice.

Keeping fish to eat: check the advisories

Some waters carry fish advisories because of chemicals such as mercury or PCBs. The EPA says states, territories and tribes issue advisories for locally caught fish and shellfish, and that the EPA and FDA advise people who are or might become pregnant, are breastfeeding, and children to pay special attention to fish consumption advice. Look up your state’s advisory for the water you fish before you plan a fish fry.

Boating rules every angler should know

Lots of fishing happens from boats, kayaks and canoes, and the U.S. Coast Guard’s federal requirements apply to all of them. The key ones for anglers:

  • Life jackets: every recreational boat must carry a wearable, Coast Guard-approved life jacket (PFD) for each person, in good condition, the right size and readily accessible (not in a sealed bag or locked hatch). Boats 16 ft and longer, except canoes and kayaks, also need a throwable device within reach.
  • Kids: children under 13 must wear a Coast Guard-approved life jacket while the boat is underway unless they’re below deck or in an enclosed cabin; if your state has a different child-wear rule, the state rule applies on its waters.
  • Engine cut-off switch: on boats under 26 ft, the operator must use the installed cut-off switch link (the “kill switch” lanyard) when running on plane or above displacement speed. If you fall out, the engine stops.
  • Boat sober: alcohol was the leading known factor in fatal boating accidents in 2024, behind 20% of deaths, according to the Coast Guard.
  • Boater education: many states require a boating safety course or card to run a motorboat, often by age or birth year. The Coast Guard points boaters to their state boating agency for these rules.

The Coast Guard also says you and your passengers should always wear your life jacket when underway, and the numbers show why: in 2024, three-quarters of boating deaths were drownings, and 87% of those who drowned weren’t wearing one. A fishing vest like the Onyx Air Span Angler (about $90) is approved by the Coast Guard and Transport Canada and comfortable enough to wear all day. More choices on our fishing gear page.

Angler etiquette: the unwritten rules

  • Give people room. Don’t crowd another angler’s spot, cast across their line, or motor through water someone is fishing. On a trout stream, don’t step in right above or below someone; ask or move on.
  • Ramp manners. Load and unload gear in the parking area, then launch or pull out quickly so the next boat can go.
  • Watch your wake near anglers, kayaks, docks and shorelines.
  • Look behind you before you cast. Fishhooks cause most fishing-related head and neck injuries in children, usually in the face.
  • Pack it out, including old line, which tangles birds and other wildlife. Respect private property and posted signs.
  • Clean, drain, dry. Remove plants and mud and drain the boat, livewell and bilge before you leave a launch, to stop invasive species. In some states, Texas among them, it’s the law.

Tournament anglers live with one more layer of rules: each circuit’s rulebook covers boundaries, check-in times, live-fish care and penalties. See our tournaments and organizations page, and our fishing with kids page for family-friendly rules of thumb.

Fishing rules questions

At what age do you need a fishing license?

It depends on the state. In many states, including California, Colorado and New York, anglers 16 and older need a license, and younger kids fish free. Check your state fish and wildlife agency’s website for the exact age and price.

Where do I find fishing limits and seasons?

In your state’s current fishing regulations, published by the state fish and wildlife agency online, in an app and as a printed booklet. Individual lakes and rivers can have special rules. For federal ocean waters, NOAA Fisheries publishes the rules by region.

Do I have to wear a life jacket while fishing from a boat?

Federal rules require one wearable life jacket per person on board, and children under 13 must wear one while underway unless a state rule differs. Some states require adults to wear them in certain boats or seasons too. Either way, the Coast Guard advises everyone to wear one; most people who drown in boating accidents weren’t.

How long can a fish be out of water before release?

As little as possible. NOAA Fisheries says less than 60 seconds is ideal, and unhooking the fish in the water is better still. Wet your hands, support its body and let it swim away on its own.

What is a descending device?

A weighted clip, hook or box that carries a fish caught in deep water back down to depth before releasing it, so it can recover from barotrauma. It’s required when fishing for reef fish in Gulf federal waters under the DESCEND Act.

Rules feel like paperwork until you realize they’re why your favorite lake still has big fish. Buy the license, know the limits, release fish gently and wear the life jacket. Back to the fishing hub, or see fishing injuries and fishing day. Other sports have their rules pages too, like soccer rules.
