Bridging the Understanding Gap

FEATURED PROJECTS:


Projects:

Regulators, stakeholders, and conservationists often have conflicting perspectives on solutions to fish population and aquatic habitat issues. Cramer Fish Sciences combines the extensive experience of its staff with a core discipline in fisheries sciences to help bridge that understanding gap.

Most of our senior scientists have served one to three decades as fish biologists with state, federal, and tribal fisheries agencies. We have studied virtually all major salmonid and sturgeon populations in the Pacific Northwest and have gained exceptional insight and influence in the fisheries profession.
