Costco's Wild caught Alaskan Salmon is from Trident Seafood, the largest US vertically integrated seafood company. http://tridentseafoods.com/Our-Story
It tastes fine to me but not sure how different they are. Prior to having a Costco nearby, I bought Trader Joe's, these are better packed. Good the entire process from family owned boats to canning is managed by a US company. I think I saw a Vital Choice product at Costco too (?)
