Estimating Fish Weight
Wondering how much that salmon weighs and don’t have a scale?
Did you release your trophy king and wonder how much it actually weighed? In Alaska, we are often fishing without any cell service and have no access to a weight calculator app. Fortunately, the fish length-to-weight formula to estimate their size is quite easy to remember and follow!
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. As your full-service Kenai River fishing guide team, we always recommend using a soft measuring tape and keeping the fish in the water as much as possible to ensure its health during the measurement process.
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.
