Formulas for Estimating Fish Weight

Marty Seldon recently reposted formulas for estimating fish weight on Dan Blanton’s bulletin board. In summary the number used for dividing into the total of Length X Girth squared to get the estimated weight is 800 for large-girthed fish, 900 for slender fish — implying that a fatter fish should get a weight “bonus.” Still not sure how accurate the results are for various species, or what the margin of error might be.
