Marine scientists Jerry Ault and Jiangang Luo have come up with a new “ellipsoid” formula–complemented by the “Tarpon Master” version 1.0 app for iPhones–to instantly estimate a tarpon’s weight.

The real shocker in the story, though, is that, according to Ault, the old girth-squared times length divided by 800 method  was terribly innacurate. “What I found was, ‘Oh, crap, it’s negatively biased,'” Ault said. “It underestimates weight by more than 15 percent.”
