Let that sink in for a second and then consider the decline of salmon runs in the Pacific Northwest and BC.
Combined, Russia, Alaska and Japan introduce five billion salmon – mostly pink and chum – into the Pacific Ocean each year through commercial hatcheries.
Some scientists have suggested that these hatchery fish may be at least partly responsible for the decline in sockeye, chinook and other wild stocks.

Let’s also consider that said Pacific-based Pink salmon have been making uncheduled guest appearances and even doing some successful spawning gigs in Scots and Irish Atlantic salmon rivers in recent years. As George Orwell very nearly wrote, in a book that featured pigs taking over a farm, some salmon are more equal than others.
