I was reading the Feb issue of the NC Sportsman Magazine. I had to buy it when I saw the cover. It boasted a new state record for striper and had teasers for specks. (I think the tackle monkey has got a cousin) Anyway, the article mentioned using a length and girth measurement to estimate the weight of the fish. I seem to remember forgetting about this, so I did a little research online. I figured I would share what I found and I can usually depend on the crowd 'round here to set me straight if I'm way out there.
For striper or drum (or other fish with similar body shape) use:
((Length x Length) x Girth) / 1200
So for a plump drum 22" long and 15" around = 6.1 lbs
For more slender fish like specks use:
((Girth x Girth) x Length / 800
So for a plump Trout 22" long and 15" around = 6.2 lbs
I figured the first formula was close enough for my uses, so I made an excel spreadsheet and laminated it. I plan to toss it in the tackle box and try it out on the next few fish I catch.
Send me a PM if you want a copy of the spreadsheet and I'll send it to you.
I couldn't find a formula for flounder, but I would be interested. I imagine it would be something to do with lenght, thickness and distance between the eyes!
