Farmed fish prey on wild salmon !

From Alexandra Morton's blog:

According to a Marine Harvest press release 40,000 Atlantic salmon escaped from their pens in Port Elizabeth in Knight Inlet on Oct. 21. Two days later commercial fishermen were catching them 40 km away.

I examined 20 Atlantics caught on the north shore of Malcolm Island and one had a salmon smolt in it's stomach. There are not many salmon smolts in the area at this time of year so it was surprising this Atlantic managed to find and consume one in only two days out of the farm. This picture shows the partly digested salmon smolt from this male 8 pound Atlantic salmon.

When 1,000s of wild salmon, herring and blackcod juveniles get lured into fish farms by the lights and food, it is hard to imagine the farm salmon don't eat them.
