“Dont know what they would be fed if they were around.”
As far as I understand it, actual “farm raised” fish are fed a corn-based diet. Kind of like fish chow. That’s why they have to artificially dye farmed salmon orange. Without their natural sea diet they are just not salmon colored.
On the bright side, I’m told that fish farms are a great place to see bald eagles feeding. :-)
