As far as harassing spawners goes Bronzefly is right. If you fish the bank in the spring you are going to catch some spawners. Even if you are fishing deeper water. On a clear water spring i have seen fish spawning on clear lake where you would not expect them. As far as sight fishing goes it sure is hard not to throw at fish you can see, but I don't have the patience to do it for to long. Fisheries have survived so far, although in urban areas with lots of meat fishermen it must be really hard to see stringers of big bed fish.
