I haven't had luck in getting creek chubsuckers(CCS) to reproduce in a pond, but I am still trying. This will be my second spring. I think I may have immature fish in the pond, which maybe why I couldn't get a spawn. CCS are found in a number of mill ponds and reservoirs around my house but they all have streams that feed them and from what I understand, the CCS ascend the streams to spawn in the spring. If you could get CCS to spawn in a pond environment, I think they would be just as good a forage fish as lake chubsuckers(LCS). They don't get quite as large, which may be a plus, depending on your situation...

AP, LCS and CCS are both acid water tolerant, they actually prefer it. So they may be a good option for additional forage for your pond.
