Citation: MITCHELL, A.J. COPPER SULFATE TREATMENTS FOR AQUATIC SNAILS THAT CARRY CATFISH TREMATODES.. THE AQUACULTURE NEWS. 2000. pp.1,2,10. Technical Abstract: Aquatic snails transfer trematodes from birds to fish and by reducing the number of snails the potential for diseases caused by the trematodes is lessened. This article discusses a shoreline pond treatment designed to kill aquatic snails that occur in the waters at the pond edges while not harming fish in the pond. Two treatments at three different rates were tested for efficacy against the rams horn snail. The best treatment appears to be a copper sulfate solution applied in a 6-foot swath in the waters along the shoreline of a pond. Ten pounds of copper sulfate in solution were put out over 250 feet of shoreline. Survival of snails in the treatment was 0% while in the controls 69% of the snails survived. The treatment appears very promising.
