Licensing and Regulations
You must purchase a Florida recreational fishing license to fish for blue crabs. Florida has a shoreline fishing exemption for recreational fishermen, but it applies only to those using no equipment other than a hook and line. Because crabbing uses traps and dip nets, it falls outside of the exemption.
A recreational fisherman may have five crab traps set at any time. If you have more than five traps then you are classified as a commercial fisherman and you must obtain additional licenses. You must pull your traps manually to retain recreational status. All crab fishermen must set their traps away from navigational lanes and pull the traps only in the daylight.
Limits
You may take up to 10 gallons of whole crabs per day. There are no size limits on specimens. The only restriction on individual crabs is that you may not take egg-bearing females; however, the Florida Fish and Wildlife Conservation Commission recommends that crabbers release all female blue crabs. Males mate several times, while females usually only mate once in their lifetimes. Returning the females to the water helps to encourage population regeneration. Female crabs are generally found in areas with higher salinity than the areas in which males live, and each female joins the males only once during her lifetime to mate.
