The Oregon State Ichthyology Collection (OSIC) contains nearly a quarter million preserved specimens of fishes, as well as associated genetic resources. It is a biodiversity library focused on documenting, understanding and protecting the fishes of the Pacific Northwest and beyond.

The OSIC supports research on taxonomy, biogeography, genetics, evolution, conservation, anatomy and ecology, loans specimens to researchers inside and outside Oregon, engages students in classes on ichthyology and fish systematics, and hosts school groups for hands-on educational activities using an extensive teaching collection.
