What is a hybrid salmon in the Great Lakes?

Pink Salmon and Chinook Salmon can hybridize. These hybrids are called “Pinooks.” Pinooks have variable characteristics and their appearance can be similar to either parent species.



In the Great Lakes, the most common hybrid salmon is a cross between a Chinook Salmon and a Pink Salmon, often nicknamed a "Pinook." These hybrids occur naturally because both species often spawn in the same rivers at the same time. A Pinook can be difficult to identify because it often shares physical traits of both parents: it might have the larger, more robust body of a Chinook but the smaller scales and distinctive spotting pattern of a Pink Salmon. Another well-known hybrid in the region is the "Splake," which is a cross between a Lake Trout and a Brook Trout, though these are typically produced in hatcheries rather than occurring purely in the wild. While Pinooks are fertile and can occasionally be caught by anglers in Lake Huron or Lake Superior, they do not form a stable population of their own. For fisheries managers in 2026, these hybrids are a fascinating indicator of how different Pacific salmon species have adapted to the unique, non-native ecosystem of the Great Lakes since their introduction in the 1960s.

A salmon fishery finally was established when 15 million coho salmon and 6 million chinook salmon were planted as smolt in the Great Lakes in 1966-70. In 1970, for example, 576,000 coho salmon (12% of those planted in 1969) were caught by anglers in Lake Michigan.

White-fleshed king salmon don't have the genetic ability to break down their food and store the red-orange carotene in their muscle cells. The marbled flesh color sometimes found in king salmon comes from their limited ability to metabolize carotene, causing the flesh to take on a marbled look.
