Hybrid species of fish

The chinook × coho salmon (Oncorhynchus tshawytscha × kisutch), or the chinoho,[1] is a hybrid fish. Although earlier examples have been known, such as ones found in Lake Ontario and northern California,[2][3] second-generation individuals were discovered in the Cowichan River in Canada in 2019.[4]
