Interpretive Summary: Four studies were done comparing various treatments of copper sulfate (CuSO4) on the survival of golden shiner and fathead minnow (Both economically important baitfish) that had columnaris disease. The treatments were observed for their ability to reduce mortality in well water. In experiment 1 and 2 treatment rates were applied flow-through daily for 5 consecutive days; control fish were untreated. The survival rate of was higher in CuSO4-treated fish compared to untreated fish. Static applications of CuSO4 were tested in experiments 3 and 4. Treatment levels were approximately 0.25x, 0.5x, 1x, and 2x the recommended rate. The survival was improved in both fish showed that 0.5 to 1 times the normal recommended rate gave the highest survival.
