This is the real Chilean Sea Bass. I received 4 to 5? They are a nice size, no need to trim off bottom(Skin) like Salmon because it’s not there. I cooked mine in my air fryer frozen and not frozen. If frozen I do 17 mins & non frozen maybe 12 mins. Use a temperature gauge because everyone’s Air fryer has different temperatures. I have Gastroparesis & this doesn’t affect me at all. As a matter of fact, it helps with my GI issues. The buttery flavor that Chilean Sea Bass already has, its ok to use a butter spray on it then sprinkle w/various herbs. Salt should be limited with this fish. I use Onion Powder, Garlic, Basil & seasons of such. I will continue to order.
