The straight line distance measured from the tip of the nose to the fork of the tail of a fish.
the length of a fish measured* as the distance between the tip of the snout and the most anterior point of the fork or ‘V' of the tail. This is the measure commonly used for the recording length of commercial fish species because it is usually little-affected by damage to the tail fin; c.f. total length. * From point to point—not, for example, by laying a tape along the body surface, which would result in a longer measurement for full-bodied fish like tuna.
The length of a fish as measured from the tip of its snout to the fork in the tail.
A fish length measurement from the tip of the nose to the fork of the tail fin.
The measurement from the tip of a fishâ€(tm)s snout to the fork in the tail.
