The Columbian Salmon is a species of salmon native to the Great Lakes. They resemble very greatly to the nonnative Atlantic salmon, but with a much more dull coloration. They are predatory to much of the native small fish species. This salmon species is not endangered, but is greatly declining due to the nonnative Atlantic salmon, but the most hazardous species in its environment are introduced whales. Conservationists are trying to help preserve this salmon species by hunting only the nonnative salmons, use genetic engineering on this salmon species to tolerate nonnative species, and even cull some whales out of the Great Lakes.
