Catfish is pretty simple. Throw smelly bait out and wait. Striper fishing tends to differ where you are doing it at. I've fished for them in Ca and NY. In NY we used to go fishing for them in Catskill where Catskill Creek meets the Hudson River. The way to do it there was take a heavy pole for striper, and a light pole with crappie jigs and catch yourself a herring. Then attach your live herring to a line with a big bobber, and let it swim around. In CA in the Bay Area and Delta live mud suckers were your best bet using a sliding sinker rig with a 3 ounce weight(flat or ball). The same works on coastal places like Pacifica, but use at least a four ounce weight that is pyramid shaped. Using the ball or flats your line will move all over the place with the current, and maybe even back to shore. Fishing in the channels going to San Luis reservoir you will use a nice big striper jig. They are basically gigantic crappie jigs. San Louis Reservoir proper anchovies live or frozen on a sliding sinker rig with a 2 or 3 once weight is sufficient.
/Good luck and have fun.
