Is your question why would we need to supplement our wild-caught salmon with closed containment salmon?
Customers want fresh product year round. They don't accept discontinuous supply as they used to. We sell these year round now, but there used to be a season.
So we sell as much fresh, wild product for as long as we possibly can. Then we supplement that with frozen, wild-caught product, and then the next choice, when customers want exclusively fresh out of season, is to have closed containment salmon. That's the niche that penned salmon filled when it started in the eighties, the off-season fresh product. Consumers want product year round, so we have to find a method that we believe is sustainable to look after our customers.
