The Gilbert Ichthyological Society, or GIS, is a group whose primary purpose is to foster communication in the Pacific Northwest concerning all things ichthyological. The Society honors Charles Henry Gilbert, a pioneer of early ichthyology in the western United States, who was either solely, or through collaboration, responsible for describing 620 species of fishes.

Members of the Society are ichthyologists and fishery biologists from Washington, Oregon, and California, working for State and Federal agencies, Universities, and private industry.

Meetings are held annually and alternate between locations in Washington and Oregon. In fall of 2018, the Society will convene at the H.J. Andrews Experimental Forest in Blue River, Oregon, for our 30th meeting.

We invite you to explore our site and learn about the rich history of our Society and our Society's namesake, Charles Henry Gilbert.
