Fish found in Cowichan River have genes of both coho and chinook salmon

Tissue samples revealed the fish are second-generation hybrids, meaning they are the spawn of hybrids.

The hybrid fish, according to Araujo and Duguid, are a rare find in Canada and are likely the result of drought in the Cowichan watershed, which has impacted when and where coho and chinook spawn.
