The Wild Salmon Center (WSC) is an international conservation organization that works to protect wild salmon, steelhead, char, trout and the ecosystems on which these species depend. Headquartered in Portland, Oregon, United States, the WSC works with communities, businesses, governments, and other non-profits to protect and preserve healthy salmon ecosystems in the North Pacific. WSC programs range in location from Russia, Japan, Alaska, British Columbia, Washington State, Oregon, and California.

The rainbow trout is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead is an anadromous (sea-run) form of the coastal rainbow trout (O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead.
