Glad you got to go fishing and thanks for details report. It's good to know that their stomachs are full of shad
I can't tell too well on blue belly it being upside-down plus coming from shallow water thus it's belly is not puff up like those from the deep. Looking at pic bluecatfish stomach looks sagging. Not being critical on your report, I am just thinking about the Twak slump theory thread... am thinking those fish did not eat as much as they should this winter and that will affect how much they will spawn. Blue catfish will generally lay about 20,000 eggs per every 10lbs of body weight.
