We'd have to get back to you with specific information in terms of monitoring in general and how long we've known about sea lice. I mean, sea lice are naturally occurring organisms that we know have been around for literally thousands, if not tens of thousands, of years. We're certainly well aware of its occurrence in the environment, and for many years have noted that it occurs on a number of marine organisms on both the east coast and the west.
More recently and more specifically, there has been a dedicated monitoring program in the Broughton region. I can't remember the exact date, but from approximately early 2000 there has been a dedicated monitoring program for un-farmed and wild juveniles in the Broughton region.
