I fished Lavon yesterday. We caught several fish. I do not have a scale so we measured the 3 bigest fish. the measurements were length and girth. 47 x 28, 42 x 27, and 38 x 25. Does anyone know of a reliable formula for estimating the weight of catfish?

I took pictures but I can't find the cord to upload pics to my computer. Its not a mini USB its for my sony camera model DCR SR200. As soon as I get one I will post pics.


Here is a pic of my personel best caught at Lavon almost three years ago.

Scales are cheap.

I found this on a TPWD website.

How can I estimate the weight of a fish that was caught and released?

You will need to have the length and girth of the fish to calculate an estimate. This formula works for all fish, although the example is for largemouth bass. To get weight in pounds, square the girth in inches (girth multiplied by itself) then multiply this times the length in inches. Divide this product by 800.

For example, we can use one of the recent ShareLunker bass. The girth was 20.25 inches and the length was 26 inches. First, take 20.25 x 20.25 to get 410.06. Multiply this times 26 to get 10,661.6. Divide this by 800 to get 13.33 pounds.

Hope it helps.
If my two brain cells are still working, according to my "old math" your weights would be respectively, 46.06#s, 38.27#s, and 29.68#s.
Not a bad day of catfishing.

I couldn't find any shad so I went to the grocery store and bought two items, mixed them together and they produced big cats.
Don't think I'll be wastin my time hunting shad anyomre. A friend told me about this bait, claimed it would out fish shad 3 to 1. It sounded like a typical fishin fabrication to me, but he wasn't kidding. He also said not to tell anyone. He reads this forum so don't bother asking.

So why did you even mention it. Thats just teasing! LOL so just PM me and give it to me. We dont even fish in the same region of texas!

What's this got to do with measuring fish. Scales are still cheap.

My guess is hot dogs and anise oil

"A friend told me about this bait, claimed it would out fish shad 3 to 1"

Oh yeah, the same bait I use, its been banned in nearly every nation and several states as an unfair advantage.

And so what is it? Come on guys, can let your ole pals on here know, especially us from lower cental texas. Ones you wont be competeing against on the same body of water.

No way spud I'm sworn to secrecy, took a blood oath

I once caught a blue on it so big it couldn't be weighed on normal scales, but the negative weighed eleven pounds .

Where's the love????

MAN! If those calculations are correct, I had the lake record Blue Cat on RC!!! I did set him free, so he�s out there some where�.. SOMEONE go get him!

What is this secrete bait, that you buy from grocery stores and mix up. Someone must spill the beans.
