Yes, I understand.
It's a very standardized procedure at the farms, taught by the veterinarians who attend those farms and the provincial government as well.
By the way, just so you know, there's a flotilla of cages often, maybe 10 to 12. The farms are instructed to pick one cage as the reference cage, and that cage will be counted every month. And then the farm is at liberty to pick two other cages on the site at random or at convenience. So in total every month they must count lice from three different cages. From each of those cages they're going to count 20 fish—20, 20, and 20, so 60 fish altogether. The fish are collected by a box seine or a big seine. So many fish are gathered into the corner, thousands usually, and then what happens is there's an anesthetic tote presented there. The fish are scooped up randomly.
By the way, in that collection of fish, back to the situation we were talking about, 80% were eating the medication and 20% weren't. Remember that story earlier on? When you collect these fish, not only do you collect the robust fish but you're likely to collect the slowest, insubordinate fish that are likely to have more lice on them, because they can collect in the corners.
So they collect them up in the corners, they put a dip net in, and they randomly choose fish. They put them into an anesthetic bath, the fish go to sleep, and they count the numbers—but not just the numbers, they categorize all of the different lice stages that they are seeing.
The only thing to add to this is that we audit that on a regular basis, 70 times a year.
