  • standard length

    Measurement taken from the tip of the snout to the midlateral, posterior edge of the hypural plate or posterior edge of the last vertebra, thus excluding the caudal fin.

It is the standard scientific measurement used for most fish species because the caudal fin easily becomes damaged in preserved specimens. Abbreviated to SL.
