New Zealand Mud Snails
Eradication of New Zealand mud snails from a state fish hatchery
Arizona fish hatchery controls New Zealand mud snails while preserving fish stocks
New Zealand mud snails have successfully been eradicated from Arizona’s largest fish hatchery dedicated to the production of rainbow and brown trout. Fish mortality rates were within normal operational levels at a low dose of EarthTec QZ. Without an effective treatment, complete eradication of the fish stock and sanitation of the hatchery would have been the only alternative, representing a major monetary loss for the state of Arizona.
