Sure.
There's been an immense amount of study done on sea lice on the west coast. The effect of sea lice on wild salmon, especially in the juvenile stage, is all relatively new. There was hardly any a few years ago, and now we have quite a bit.
The original concern that the sea lice would be decimating the wild salmon has had to be modified, because we know that wild salmon have an immune response to sea lice and most of them can shed sea lice fairly quickly.
We now know that there is a concern with those species of salmon that go to sea when they're very small. Those are chum and pink salmon. The first few weeks they're in the ocean is the time of the major risk, and it's to those two species. They can be damaged by sea lice that attach to them before they get to be more than about half a gram in size.
So we're working together with regulators and with other researchers and people with environmental concerns within the environmental movement to focus our management on mitigating the risks to the wild salmon during the part of their life cycle when they're that small.
