That is my guess. I should have used a scale and took a photo of the whole fish on the scale and then on a measuring board so that all of the charts could be posted to either prove or disprove my guess. Just trying to be friendly and point others who might want to get out while the fishing is good in the right direction. I have been fishing a long time and have a pretty good idea what fish weigh but having said that, I am a fisherman and probably do exaggerate at times. I think one of the spots I caught was very close to if not over 4 lbs and the others were like the one in the picture, just good solid fat fish.
See you on the lake and have a great day!
