Acute toxicity of copper sulfate in juvenile red drum (Sciaenops ocellatus) and the establishment of safe methods to control parasitic disease
A series of static 96 hour acute toxicity tests were performed on juvenile red drum of different sizes. The tests were implemented to assess the acute toxicity of copper sulfate to juvenile red drum and establish narrowly defined guidelines for its usage in the treatment of Amyloodinium ocellatum an...
