Abstracts of Aquaculture America 2014: Taking Aquaculture to New Heights through Technology, Marketing, Collaboration, February 9-12, 2014, Seattle, Washington. p.252.Interpretive Summary:
                                Technical Abstract: A study was conducted to compare the therapeutic effects of copper sulfate (CuSO4), when delivered in either a flow-through or static system, on the survival of golden shiner (Notemigonus crysoleucas; Fig. 1A) and fathead minnow (Pimephales promelas; Fig. 1B) infected with Flavobacterium columnare (Fig. 1C).  The treatment regimens were investigated for their ability to reduce mortality in well water that had 218 mg/L alkalinity, 112 mg/L hardness and pH of 8.5.  Treatment rate of CuSO4 was 2.2 mg/L and applied as flow-through at 24 h intervals on consecutive days; control fish were untreated.  The study durations were 7 days with the majority of the mortality occurring in the first 5 days.  The survival rate of CuSO4-treated golden shiner was 68% and was 77% for fathead minnow in the flow-through system; both were significantly different from the untreated control fish (39% survival for golden shiner and 33% survival for fathead minnow).  

Static applications of CuSO4 were investigated at the treatment levels of 0.5, 1, 2, and 4 mg/L (approximately 0.25x, 0.5x, 1x, and 2x the recommended rate) to reduce mortality of golden shiner and fathead minnow infected with F. columnare; control fish were untreated.  The survival of fathead minnow was 28, 52, 47 and 35% in the 0.5, 1, 2 and 4 mg/L CuSO4 treatments, respectively; survival in the untreated control was 7%.  The survival of golden shiner was 58, 65, 75 and 70% in the 0.5, 1, 2 and 4 mg/L CuSO4 treatments, respectively; survival in the untreated control was 48%.
