Overview
Most finfish size limit regulations of the Florida
Fish and Wildlife Conservation Commission (FWC) use either Fork
Length or Total Length.
These measurement methods provide a consistent,
well defined measurement technique. These methods encourage angler
compliance with fishery management regulations.

How to Measure Stone Crab and Spiny Lobster
Stone Crab
Measurement
Stone Crab claws must measure at least 2 3/4-inches
in length measured by a straight line from the elbow to the tip of
the lower immovable finger. The forearm (propodus) shall be deemed
to be the largest section of the claw assembly that has both a
moveable and immovable finger and is located farthest from the body
of the crab.

Spiny Lobster
Measurement
Spiny Lobster must have a minimum carapace length
of greater than 3-inches and the measurement must take place in the
water. The carapace is measured beginning at the forward edge
between the rostral horns, excluding any soft tissue, and
proceeding along the middle to the rear edge of the carapace.
