Fish Weight Estimator

Estimating Fish Weight

Wondering how much that salmon weighs and don't have a scale?  Here's how to accurately estimate the weight of a fish like a salmon from measurements of length and girth. The girth is measured at the thickest portion of the midsection and the length is measured from the tip of the nose to the tip of the tail. All measurements should be in inches.

Weight Estimator Formula:

Weight (lbs.) = length (in.) x girth (in.) x girth (in.) / 740

Example: A king salmon is 52 inches long and has a girth of 30.5 inches.
The calculation is as follows:

Weight = (52 x 30.5 x 30.5) / 740 = (48,373) / 740 = 65.37 lbs.
