Sturgeon Length/Weight Conversion Table

STURGEON LENGTH / WEIGHT

This chart is a copy of a  WDFW  Lower Columbia chart

After 2009 the State of Washington Department of Fish & Wildlife
measurement is taken to the fork length not overall length

NOTE the Canadian chart shown below lists the fish weights heavier than Washington chart

The following chart was supplied courtesy of B. C. Frasier River White Sturgeon study program
These lengths are overall length

These Frasier River fish must eat better than the Columbia River ones do
