finfish size limit regulations of the Florida Fish and Wildlife
Conservation Commission (FWC) use either Fork Length or Total
These measurement methods
provide a consistent, well defined measurement technique. These methods
encourage angler compliance with fishery management regulations.
Total Length Measurement
Length is now measured from the most forward point of the head, with
the mouth closed, to the farthest tip of the tail with the tail
compressed or squeezed, while the fish is lying on its side.
Total Length Species Include:
Fork Length Measurement
regulated by fork length are measured from the tip of the jaw or tip of
the snout with closed mouth to the center of the fork in the tail.
Fork Length Species Include:
Lower Jaw Fork Length Measurement (Billfishes)
regulated by lower jaw fork length are measured in a straight line from
the anterior most part of the lower jaw (tip of the lower jaw) to the
fork in the tail.
Lower Jaw Fork Length Species Include:
How to Measure Stone Crab and Spiny Lobster
Stone Crab Measurement
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
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.
