Not to pile on but…If my understanding of the salmon lifecycle is correct I think the probability of them mating with wild stocks has been way overstreched. Salmon imprint on a water system from birth to smoltification. If Salmo domesticus follows this same pattern it would have imprinted on the rearing site or net pen area of the farm. If their migratory instincts are still in tact then they would migrate back to the fish farm when they start to reach maturity. They may find their way into a stream system close to the farm but it is highly unlikely they would just pop up a few hundred miles away. Even when wild salmon stray it hasn’t been shown to be that far from their native watershed. Just my perspective…
