Cat weight x measurement

[sparcebag]

I tried to download the chart I think dtro posted,I'm no computer wiz I cant get it.So I just caught a 44 inch flat it was all head skinny it looked bad but fought good did'nt measure girth marked length on a stick.whats a close weight ballpark??? Thanks Sparcebag

[DTro]

In order for the formula I use to work, you need a girth measurement. Your fish could have weighed anywhere from 30lb to the mid to high 40's. Once a flatty reaches 40" the girth can make a huge difference.

No matter the weight, that's still an awesome fish....great catch!

Thanks I'll take 30 it was actually an ugly fish it was so eelie lookin.If ya could and its short could I get formula? I dont want to start a long list of can I's sparcebag0 at yahoo

[harvey lee]

Either way thats a very nice fish.

Sparce,

The formula is:

Length X Length X Girth / 1275

Thanks Harvey! I been seeing the channel cats talk,Ya got to try Granitefalls area,most we catch are between 4PM-9PM

If ya need a spot I'll tell ya where we fish,you wont believe the channels we catch very few under 8, avg. probably 12-13 lbs.I dont mind sharing just so the hoards dont start showin up!We see signs of other fishers but seldom see anyone fishin,and we only go 1-2 times a month but stay 3 nights at a time,Tues.-thurs. night.let me know I'll mail the spot.

Thanks Ralph just to make sure legnth x legnth x girth divided by 1275?? its the divide sign I wonder about?

[Ralph Wiggum]

Yup, that is it!

As they get bigger.

Looking at the measurements of mine and Piers Fish.

Very close in both catagories.

LFC== 44 X 27 longer Chart wieght 41.00 Actual/tare for net. 39lbs

Pier==42.5 X 28 wider Chart wieght 38.7 Actual/tare for net 42lbs

Wondering about the est/tare wieght adjusting for the net?

It would seem as the fish get on the larger side that the margin of error seems to increase minimally. Its still with in the 3lb parameters. Seems like a pretty solid formula to this point.

Now I want to see it tested on a 50lb fish or bigger.

Come On Mates!!!!! Let someone get a hog to test this further.

thanks

Like I was saying earlier my net which I have weighed many times dry is 3 pounds 7 ounces.....just got back from bullhead fishing and I dunked in the lake and it bounced around 4lbs even so 45lb-6ozs with the net minus 4lbs would put my fish at 41#'s 5 ozs roughly and it was just over 42 1/2"s but not quite to 42 3/4 so it was pretty close on the Chart about 2 lbs off well within the margin of error.

Rock solid formula...thanks Dtro!

[DTro]

Ok, there is another way to do it that might be more accurate.

LXGXG/825

I will use a lot of this data at the end of the year to tighten it up a bit. I'm guessing and from a few comments that it might actually be better squaring the girth.

DTRO this was close on my flat last night.

29L

18.5G

29*29*18.5/1275= 12.2

Actual weight 10.8

[DTro]

The two fish I caught last night were within 1.5 lbs also.

I'm convinced that up to 30lbs this formula is rock solid. Questions remain on those over 30 fish though.

How bout some more data guys

[audemp]

I hope I can get into one worth weighing to see how close the chart is. Only got one so far this year at about 5 lbs. Still, he sure woke me up went screaming off with my bullie almost gave me a heart attack. I love catchin them at any size. I think they are the coolest fish that swims in the rivers. We sure are lucky to have them in MN.

I like that second formula for bigger flats it seemed to be very close to both Larrys and my fish.

Thanks Dtro.

I concur at this point. Would like to see more data.
