Thank you. That's a very good question.
The fish health program is largely based on a database system that has an algorithm. At the beginning of each quarter of the year, we put in the farms that are currently active with growing fish in that quarter. The computer will randomly choose which sites we are going to go audit and visit, not only for health visits but also for sea lice monitoring and audits.
Our staff, once that's chosen, will communicate with each of the farms, and over the next three-month period will go and visit those particular sites. They will coordinate it with the carcass collection days, whether that be coordinating with a third-party diving company, or sometimes the carcasses are brought up by a pump.
So we go out and we attend the carcass collections, collect the samples from the selected group of dead fish, and bring them back, where they are analyzed very thoroughly in the laboratory in the Animal Health Centre in Abbotsford.
