First Coast Crabbing Guide
Learn the simple hand-line method, set a legal recreational trap, identify the local catch, and know the rules before you go.
Before You Go
A Florida saltwater fishing license is generally required to take saltwater crabs. A shoreline-only license applies only from shore or a structure fixed to shore—not from a boat, a shore reached by boat, swimming, or diving. Check exemptions before harvesting.
Anyone age 16 or older using a standard blue crab or stone crab trap must also complete the matching no-cost annual registration—even if normally exempt from a fishing license. Blue-crab numbers begin with “B” and stone-crab numbers with “S.”
Permanently and legibly attach the owner’s full name, address, and FWC registration number. A buoy must be at least 6 inches and display an “R” at least 2 inches high. Dock-fished traps do not require a buoy.
Two Easy Approaches
Best for docks and creek banks
Why it works: Hook-and-line gear and dip or landing nets are legal for blue crab, and no trap registration is needed when no standard trap is used.
Best for soaking over moving tides
Never touch someone else’s gear: Tampering with another person’s trap, line, buoy, or catch is illegal—even if it appears abandoned.

This is a field summary, not the complete rule text. Verify your exact trap against the current FWC diagram before setting it.
Identification & Harvest
Callinectes sapidus
Our familiar estuary crab. Look for a broad olive shell with a long side spine, blue legs and claws, and flattened paddle-shaped rear legs. Found in tidal creeks, rivers, marshes, docks, and bays.
Menippe mercenaria
A heavy-bodied crab with a mottled reddish-brown shell and powerful claws tipped in black. It shelters around rocks, oyster bars, jetties, and burrows. Only legal-sized claws are harvested; the live crab is returned immediately.
Best practice: Although both claws may be taken when each is legal, removing only one legal claw improves the crab’s chance of survival. Never take the whole crab.
Check current FWC stone crab rules →
Cardisoma guanhumi
A large terrestrial crab ranging from pale gray-blue to violet, often with one oversized claw. It lives in burrows above the tide line near coastal hammocks, mangroves, canals, and low-lying yards.
Location rule: Do not harvest from the right-of-way of a federal, state, or county-maintained road or from a Florida state park. Respect all private property.
Check current FWC blue land crab rules →Also Commonly Seen
Smaller mud, marsh, fiddler, and ghost crabs are common around First Coast shorelines. Spider and decorator crabs occur in saltwater as well. These are different from the primary food-crab fisheries above, and some may fall under Florida’s unregulated-species or marine-life rules.
Never assume “no listed size limit” means unlimited harvest. Confirm the species, location, allowable gear, and current default bag limits before collecting any crab for bait, food, or an aquarium.
