Estimated weight

I am hoping for a scientific or educated estimated weight on this LMB. It is atop a standard 15" tackle box. It is tough to get a decent photo alone in a kayak. Fish is still swimming in Hennepin county, Any help is appreciated!

Yeah I did a double take on the mouth as well. Looks like a big carp mouth. If the box is 15", fish has got to be 21" IMO.

That's a nice bass, and I know what you mean about the difficulty of taking pictures in your kayak while also trying to avoid dropping your phone in the water. I landed a 34" northern and it was a chore to get the pic of the whole fish and I have a huge kayak. Pain in the butt. I agree with the guesses. 20" and 5lbs.

Using the WAG method i think 4.5 would be a good guest. The amazing thing to me is the size of the fishes mouth. It looks very small for the size of the fish. If that is the norm keep fishing that pond as that is a young fish and there has to be some monsters in their.

That is a nice fish. Photo doesn't really let me see length too good. Could be 18ish. Could be 20ish. What strikes me is the mouth size. Usually when you get a 20 incher, you can fit your fist in their mouth, yet on this one, the picture makes it look like the mouth is full with just your thumb in it. Without seeing the girth of the fish, I'd have to say around 19 inches, 4-5 pounds. Could be bigger/longer, though. Either way, it is a great catch. Had to be a lot of fun in kayak.

Ditto on what phat said...
