Student Learning Outcomes
  1. Identify common Pacific Northwest fish species and major groups visually, taxonomically, and through keying.
  2. Describe the ecological roles of fish within their ecosystems, including connections to other vertebrates.
  3. Describe the evolutionary processes, relationships, influences, and adaptations that exist within and between different major fish taxonomic groups and have led to the great diversity of fish.
  4. Identify and describe the anatomical structures of fish and their physiological function at both cellular and organ level.
