main thing fish always eat so... you can always catch'em just a matter of changing presentation and technique. Right now(IN TEXAS) the fish are already moving up. I caught a couple of small bass yesterday down on the creek. The biggest bass are caught in February here. But you have to fish deep. They stage on drop offs near shallow water first then move up as the water warms up. When over night temps reach 50's it's time. There is no science to this just observation. Panfish, bluegill ect. (not crappie) wait a while after the bass start moving, and crappie go before the bass. Each one has its own timing. There is a ton of info out there on the science of it. Hope this helps. Others will surely add to this. Hope you do well. HOSS
