How old is a 7 foot alligator gar?

Alligator gar can live for many decades. They grow very fast when young, but growth slows with age. In general, for every additional foot the fish grows, its age doubles. A 3-foot gar is typically about 2.5 years old; a 4-foot gar about 5, and a 7-foot trophy catch might be 40 years old.
