Last Reviewed: January 2026

This guide breaks down Florida recreational blue crab laws in clear, practical language. Whether you’re crabbing from shore, dock, kayak, or boat, this page covers legal size limits, trap requirements, entry devices, tagging rules, and buoy markings required to stay compliant.

This guide is specific to recreational harvest only.

Always verify updates directly with FWC before each season.

Quick Compliance Snapshot (Florida Recreational)

Minimum Size – How to Measure Blue Crab Correctly

Recreational blue crabs must measure at least 5 inches across the carapace, measured from tip to tip of the lateral spines.

Measure:
• Across the widest part of the shell
• From outer spine tip to outer spine tip

Common mistakes:
• Measuring inside the spines
• Measuring straight across the shell without including the points
• Guessing instead of using a gauge

Always measure at the widest point across the top shell.

Egg-Bearing Females (“Sponge Crabs”)

It is illegal to harvest female blue crabs carrying eggs. If caught, they must be returned to the water immediately and unharmed.

Recreational Trap Requirements (Florida Only)

Florida recreational crabbers may use up to 5 traps per person.

Each recreational blue crab trap must include:

At least three escape rings
Escape rings with a minimum 2 3/8” inside diameter
A compliant entry throat opening (see below)
A required biodegradable component
Proper trap marking (name, address, registration number)
Proper buoy marking (6” buoy with 2” “R”)

Entry Throat / BRD Requirement (Often Called “TED”) Each funnel entry throat must either:

Be rigid and no larger than 2 inches high by 6 inches wide at the narrowest point,

Have a properly installed 2” × 6” Bycatch Reduction Device (BRD)

Many people casually refer to these as “TEDs,” but the regulation specifies terrapin bycatch reduction devices (BRDs) or compliant rigid throat dimensions. Improper or missing devices can result in non-compliance.

OceanBuilt TEDs can be bent in, fastened with hog rings, or held in by zip ties.

Escape Ring Requirement

Each recreational trap must have at least three escape rings. Escape rings must:

Be unobstructed
Have a minimum inside diameter of 2 3/8 inches
Be installed on the vertical outer surfaces of the trap

Biodegradable Panel Requirement

Each trap must contain a required degradable component designed to allow crabs to escape if a trap is lost. This is intended to prevent “ghost fishing.”

Trap Tag & Marking Requirements (On the Trap)

Each recreational crab trap must have permanently affixed:

Harvester’s name
Harvester’s address
FWC-issued unique recreational trap registration number

This information must be attached to the trap itself — not just written on the buoy.

Buoy Marking Requirements

Each recreational trap buoy must:

Be at least 6 inches in size
Display a clearly visible 2-inch tall letter “R”

The buoy identifies the gear as recreational. The registration number belongs on the trap — not on the buoy.

Common Compliance Mistakes

Missing the 2” tall “R” on the buoy
Putting registration numbers on the buoy instead of the trap
Installing fewer than three escape rings
Incorrect BRD size or placement
Measuring crabs incorrectly across the shell
