Has anyone purposefully put zebra mussels into their pond or does anyone have them in their pond? I believe here in Texas it would be illegal but I have heard that Lake Texoma now has them in it. Can they clean the water of excess nutrients reducing the risk of a fish kill? I have read good and bad things about them being in the Great Lakes. The good is that the fishing is the best ever with very clean water. The bad is that they clog up every pipe and inlet into the Lakes.
