What Is Salmon?

Salmon refers to several species of oily, pink-fleshed fish from the 100-million-year-old Salmonidae family. Salmon are carnivores that spend most of their lives in the ocean, but return to the streams where they were born when it’s time to spawn (deposit eggs). The best salmon are caught as they reach the mouth of their home river, before they start a difficult upstream migration that depletes their fat stores.
