Low-brow (and mostly unprocessed food) eater, never heard of it before.

A quick look up is, at least their pacific salmon is wild=caught MSC-certified (for all its worth). Atlantic salmon is Norway farmed and ASC cerfified again (whatever that means). Fish farms are notorious for disease and destroying the sea bed underneath (not much different from consistently dumping raw, untreated sewage onto the same seabed - something my local big city has been doing for decades but have finally almost completed a sewage treatment plant))..
