First, the pink salmon, the smallest and shortest-lived species, took over the Pacific Ocean, swarming with the help of Alaska ocean ranching until they came to represent 74 percent of the biomass of all six species in that vast expanse of blue water.
Then, with the help of Russian salmon ranchers, they gained a foothold in the Barents Sea of Northern Europe before eventually staging an invasion of Norwegian waters. Forays into streams in Scotland would follow, and then Iceland and Greenland.
Now, the Canadians believe, the Russian pinks – which trace their roots back to eggs transplanted from parents caught on the western side of the Bering Sea adjacent to Alaska – have reached the eastern shore of that nation.
