(FWC) – FWRI Crustacean Fisheries staff conduct long-term, trap-based monitoring for stone crabs. They designated eight locations along the Florida coast as study sites. At each location, FWRI researchers select four sites arranged inshore to offshore.

At each site, they set five standard commercial stone crab traps approximately 100 meters apart in a straight line, resulting in 20 traps sampled at each of the eight locations.

Researchers service the traps every two weeks by counting the catch, determining each crab’s sex and assessing individuals for injuries.

They also take measurements for carapace width and claw length, and determine whether claws are original or regenerated.
