Catch of the Day- Rainbow trout

posted by Veronique Koch on 25 February 2013

Today’s featured seafood is the rainbow trout.


Rainbow trout (Oncorhynchus mykiss) are naturally found in tributaries around both sides of the Pacific Ocean, and are farmed around the world.


They are often introduced to lakes (which reportedly gives them an earthy flavor) and rivers for food, but these types of introductions can have devastating impacts on the natural ecosystem. They are also farmed in open ocean cages in countries like Chile (the world’s largest producer) and Norway.


The good news is that U.S. farmed rainbow trout are a good choice according to Monterey Bay Aquarium’s Seafood Watch Program when they are farmed in the US.


Fun fact: Rainbow trout and steelhead trout are the same species, just found in different kinds of water! Rainbow trout are born in fresh water among the rocks, but if they then migrate to salt or brackish waters they are known as steelhead trout. Steelhead trout are anadromous, coming back to fresh water to spawn.


They are the same fish, although they do have a different taste. Many people compare them to salmon in terms of their flesh, partly because they take on the same pink color as salmon from eating krill.
