Fish Weight Formula

[harryk]

Has anyone out there in fishland ever heard of a formula whereby you take the length and the girth of the fish and somehow come up with a close poundage of what that fish would weigh? A buddy of mine told me about it but it's been quite a few years since he heard how it was done and he doesn't remember now. Let me know if you know.<br><br>

sumbody correct me if i`m wrong....butt it`s 1 r da other...<br>lenght X lenght X girth divided bye 1200.....i thank.....Bsafe!..C-ya!<br><br>

The following formulas, published by the Minnesota Department of Natural Resources, take body shape into account:<br><br>Walleye Length³ ( 3,500 (length X length X length ( by 3,500)<br><br>Pike Length³ ( 2,700 <br><br>Sunfish Length³ (1,200 <br><br>Bass Length² X Girth ( 1,200 <br><br>Trout Length X Girth² ( 800 <br><br>The formula for pike is not accurate when applied to large, heavy muskies (it makes them far too large), although some people use Length X Girth² ( 800 for these fish (which is also above the actual weight by a small amount). Very heavy specimens of any species are often tough to fit into these formulas because their bellies tend to become distended, and fish of equal lengths can have much different thickness (just as every human being that is 68 inches tall doesn't weigh the same, even though there are average weight charts).<br><br><br>[laugh] How about a good laugh?<br><A HREF="http://www.bigfishtackle.com/comics.htm " target="_new">http://www.bigfishtackle.com/comics.htm </A> <br><br>Mike H
