Bonefish & Tarpon Trust

Bonefish Weight Calculator

Length to weight calculations are based off measurements from 453 bonefish caught in the Florida Keys. The girth of an individual tarpon varies quite a bit, but bonefish girth is generally consistent across individuals, with a few exceptional fish that are very fat or very skinny. Therefore, just entering a fork length measurement gives a fair estimate of how much your bonefish weighs.
