parker,

I take it this is a buck silver? If so, they have a body a little more similar to a large lake trout or char. After browsing around, the formula generally used on those species is

Length x Girth x Girth /800

Rather than: Length x Girth x Girth/775 which is the formula used for steelhead.

Using the first method, it's 22.99 lbs.
Using the second method, it's 23.73 lbs. (or 23 lbs. 11.7 oz.)

You decide............ laugh
