I am a fairly new boat owner and I'm trying to learn all I can about sturgeon fishing. Well, actually I have the fishing part down pretty good, it's the catching part I'm having trouble with

. Specificly, when the fish aren't in holes(like now) what do I look for? Holes are easy to find if you can read your graph but I have no idea where to look if the fish aren't there. Do I look for structure? Small depressions on flats? Edges of channels? Can someone please share a few words of wisdom? I'm not looking for anyones secret spots here, just some education so I can find my own

. Thanks a bunch.
