Book of Abstracts-Food Security for the Future: The Role of Aquatic Health, October 22-23, 2015,Mississippi State University. p. 23.Interpretive Summary:
                                Technical Abstract: Copper sulfate (CuSO4) is cheap, safe to the applicator and effective for controlling fungus on catfish eggs. Several studies were designed to determine the effectiveness and safety of CuSO4 to channel catfish eggs in pursuit of an FDA approval. 
In an effectiveness study for the FDA, we found that the optimum dose was 10 ppm CuSO4 in a flow-thru trough when treated daily until the eggs became eyed. In a safety study for the FDA, we found that 50 ppm CuSO4 was safe for catfish eggs. In a separate experiment, we found that 100 ppm CuSO4 was also safe and effective.
