But I think I may have overlooked it or something. I think you can guestimate the weight of a fish by measuring it's length and mutiplying that with it's girth measurements. Am I correct? Just curious.:smile2:

Sure. Everytime I catch a catfish I measure him and multiply inches by 1 pound 10"=10lbs:smile2::smile2::smile2: I think there is a formula but I don't know what it is.

I really don't know if this formula works for catfish, but it is the formula for estimating the weight of trout: Lenght x girth x girth divided by 800 = weight of fish

girth squared x length divided by 800 so if you have a fish that is 20" long with a girth of 12" the 12x12=144x20=2880/800=3.6lbs this is the official big game fish formula. http://www.getbentsportfishing.com/helpful/tips-and-tricks/fish-weight-calculator/

So another bit of good advice is; If you catch a fish that is bigger than your scales can weigh it is good if ya keep one of those cloth type tape measures like they use in sewing, rolled up and in your tackle box. At least that way you will get a close estimate of how big that fish is.
