Downriggin Repeat Spawner Registered: 02/28/02 Posts: 1203 Loc: Marine Area 13	Gang, Wondering how accurate this formula is for weighing fish? My guess is +/- half a pound. Maybe one of our resident biologists can help out...

The Steelhead / Salmon Weight Calculator Using the info from your 10/20 post and that formula, that fish was 9.5 pounds. I was talking with DD last night, I thought it looked like an 8 or 9 pounder, didn't look over 10 unless you're over 300! JK!!! The digital scales are pretty accurate and very humbling! A 15-20 pounder weighed on a digital scale is a really nice fish, and they LOOK bigger than they actually are. Usually by about 1/3 in my experience with estimating vs weighing. I've seen a lot of 15 pounders called 20, I've even done it, but when weighed the truth is humbling! _________________________ Seacat

Downriggin Repeat Spawner Registered: 02/28/02 Posts: 1203 Loc: Marine Area 13	There is some disparity between the two links... Bob's is probably more accurate and I'll start using that one... However, being a "honest" fisherman , I might choose the other (laughing). (Did I tell you that there was a high lead reading in the stomach contents ) As far as my weight... I do have a nice beer gut for my 220# frame!!! I don't know if I want to buy a digital scale now. I am humble.

DUROBOAT15 Spawner Registered: 09/08/02 Posts: 836 Loc: des moines	DR, I think the one you linked to is real accurate. I have used it after weighting fish on my digital scale and they are always real close. You are real close at +/- a half pound. _________________________ Chinook are the Best all else pale in comparison!!!!!

Wild Chrome Spawner Registered: 12/14/01 Posts: 646 Loc: The Tailout	I've tried using the formula's for my (mostly steelhead) fishing and have found they usually exagerate the size of the fish. I wound up taking all the measurements of my hatchery fish one season and writing them down. I still write down the measurements of the biggies. Now I can look back at comparisons to actual weighed fish to estimate the size of those I release (natives). I think a seasoned fisherman can eyeball fish more accurately than using the formulas. My 2 cents. _________________________ If every fisherman would pick up one piece of trash, we'd have cleaner rivers and more access.
