Description: Technical note
Purpose: To evaluate potential for hydraulic containment of round gobies, three questions were addressed in a series of laboratory experiments: What are the station-holding capabilities of round gobies? How is station-holding endurance influenced by substrate? Are goby movements effectively contained by hydraulic barriers? Round gobies were tested in a series of laboratory experiments to determine whether hydraulic containment of populations was possible. Station-holding endurance models, critical station-holding velocity tests, and a small, low-velocity barrier in a simulated stream all indicated that containment was feasible, but that barrier specifications would have to be adjusted to local conditions (bottom topography, substrate size, water temperature).
