Christopher Guy


  • Ph D South Dakota State University 1993


Most of my research falls within the broad mission of ecology of fishery and aquatic resources. A major, consistent research theme has been on native fish assemblage restoration, a prominent ecological and societal issue in Rocky Mountain and Great Plains ecosystems.

Research Interests

Fish ecology, fishery stock assessment, fishery management regulations and tools, native and non-native species interactions

Teaching Interests

Fisheries Science, Fisheries Techniques
