Fork length (FL)
Fork length (FL): Fork length (FL) refers to 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 the vertebral column ends. (Wikipedia)
Fork length (FL) can be specified as:- Maximum length: Size (in cm) of the largest male/unsexed or female specimen ever caught. (FishBase)
- Common length: Size (in cm) at which male/unsexed or female specimen(s) are commonly caught or marketed. (FishBase)
- [[ForkLength|Fork length (FL)]]

1) Length of a fish measured from the tip … 1) Length of a fish measured from the tip of the snout to the posterior end of the middle caudal rays. This measurement is used instead of standard length for fishes on which it is difficult to ascertain the end of the vertebral column, and instead of total length in fish with stiff, forked tail, e.g., tuna. Mostly used in fishery biology and not in systematics.
