Two recent cases of pink salmon being found in Newfoundland and Labrador rivers are most likely the result of a stocking program — just not one on this continent.
Pink salmon are native to regions around the Pacific Ocean and are rarely seen in this part of the world. They are distinguishable from Atlantic salmon because of their greenish color and the fact that adult males have a large hump on their bodies not seen with their Atlantic cousins.
What’s the likely origins of these fish? The Russians.
Starting in the 1950s there was a stocking program to transplant pink salmon into some rivers in Northern Russia that ran until 2001. The stocking program seems to have been at least somewhat successful and there’s been an explosion of them this year.
Pink salmon from Russia have been reported in Scotland, Ireland and other parts of Europe over the last year or so, which has raised concerns that they could become established and displace other fish species.
