Total Length is 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.

Where do you measure a fish from?
The overall measurement of a fish, whether it is fork-tailed or round tailed, is taken from the snout on the upper jaw to the end of the tail.
How do you measure the standard length and head length of a fish?
The standard length measurement is taken from the most anterior part of the fish, be it the snout or mouth, to the most posterior part of the last hypural bone. This is found by bending the caudal fin and noting the crease.
What is total length when measuring fish?
Total Length (TL) – The length of a fish as measured from the tip of the snout to the tip of the tail. Fork Length (FL) – The length of a fish as measured from the tip of its snout to the fork of the tail.
How can you measure a fish without a ruler?
You can lay your rod next to the fish and see how they compare. For example, if the fish is halfway between the fifth and sixth guide, when you get home, you can measure how long it is to halfway between the fifth and sixth guide. You can also tie a piece of line tight to the rod where the fish measured up against.
What is the difference between fork length standard length and total length when measuring a fish?
o Total length is the measurement taken from the tip of the snout to the end of the caudal fin (Figure 1). o Fork length is the measurement taken from the tip of the snout to the centre of a concave tail (Figure 2).
How is caudal length measured?
Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline.
Does fish length include the tail?
Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin.
