I am confused. Are GSH considered a problem species in a SMB, YP, RES pond? My pond also has lake chubsuckers in addition to the 4 other species.
Shiners are a predator of fry and eggs. This can be both beneficial or harmful depending on your management goal. A pond I manage in SE IA is stocked with SMB, WE, YP, and shiners. I don't expect any reproduction from the walleye or SMB but the growth rates have been outstanding and I plan to ladder stock every 2-3 years. The predators are overstocked and shiners are fed a starter diet. The range in size from fry to almost 9". I catch some big shiners on small inline spinners, crappie jigs, and ice fishing lures.
