Fish feed based upon the environment and the solunar tables. I've read that fish will feed to being stuffed, then regurgitate, then eat again at the "peak" times according to the solunar table. Of course, it isn't so simple as water temp and barometric pressure also affects feeding as you guys are discussing.
I had an "old timer" tell me once, that if you're heading to fishing, pay attention to the cows. If all the cows are feeding, then the fish will likely be feeding as well and vice-versa.
