Interpretive Summary:

Technical Abstract: Copper sulfate (CuSO4) is used by the catfish industry for controlling parasites and as an economical treatment to control fungus (Saprolegnia spp.) on channel catfish eggs. Several studies were designed at SNARC to evaluate the effectiveness and safety of CuSO4 to channel catfish eggs in pursuit of an FDA-approval. Use of CuSO4 is currently allowed because it falls under the category of ‘deferred regulatory status’. The following is an overview of our studies for the proposed indication ‘to control egg mortality associated with Saprolegniasis infecting channel catfish eggs’.
