Saw this today at a Whole Foods in Tucson, AZ.

Their website:

They are using the Safina Center's Sustainability Rating for Steelhead that allows for all USA caught steelhead.

I'm not usually into this type of whack-a-mole, but Whole Foods is a corporate giant who can really do some damage on the demand side if not stopped.

FYI, I have already had a conversation with the store and person in charge of buying and they are saying it is wild caught steelhead... regardless of the color of the filets
