Competition between native and non-native fishes in Bright Angel Creek and other tributaries: implications for humpback chub recovery


May 2010 - September 2012


1. Determine seasonal fish communities and food habits of fishes in tributaries where HBC are or will be translocated.
2. Determine if competition for food exists between native and non native fishes.
3. Conduct a population estimates (if feasible) seasonally on non native and native fishes.
4. Determine the estimated annual consumption of invertebrates and fish by non native fishes using bioenergetic models.
5. Make recommendations to determine if non native fishes can coexist without substantial detriment to native fishes, including the possibility of humpback chub
