Total length measurements are used in slot limit and minimum landing size regulations. Fishery biologists often use a third measure in fishes with forked tails, called Fork length ( FL ), the length of a fish measured from the tip of the snout to the end of the middle caudal fin rays, and is used in fishes in which it is difficult to tell where ...
