Good question - I'm not sure what weights are typically associated with 34" fish. My biggest cat was 48" at 60+ pounds...it's the only one I ever measured as I'm not big fish eater and release all the cats I land. There is a formula posted on CFF using length and girth as inputs to approximate weight. I think it is weight = (length x length x girth) ÷ 1,200.
My undertsanding is that one fish per angler can be harvested per day over 34" so I think the 6 anglers jug fishing would have been legal if they only had six over 34" and had their licenses. However, on a separate occasion listed above, FishnFool witnessed 14 potentially oversized cats being iced down at the ramp.
