Title: Exploring Feasibility of Proposed Control Strategies for New Zealand Mud Snails at Fish Hatcheries
Student: Rolita Louise Bruce and Jordan Nielson
Department:Fish & Wildlife Resources

Project summary

The New Zealand mud snail is an invasive species that affects rivers and streams throughout the United States. Fish movement through stocking regimes have been documented as likely vectors of spread through the gut of trout. R. Louse Bruce’s studies indicate that a portion of the New Zealand mud snail could survive transit in the intestinal track of rainbow trout. She found in several sizes of fish that 8-12% of the snails in the fish fecal material were alive and over time the snail survival decreased in the trout gastrointestinal tract.
