The main product for controlling.... And just to make sure I was clear earlier in my other response, I'm not familiar with the particular circumstances you're talking about in Quebec. I'll go back and look, and we can get back to you on that, in terms of the pilot projects or the previous ones.
With respect to sea lice, the main product that's used to control sea lice now is a chemical, or a drug rather, called SLICE, and it's administered by the feed. They mix it into the feed. The fish eats it. Essentially what SLICE does is paralyze the louse that attaches to the skin. The louse falls off and eventually dies.
Another way of treating sea lice is through what are called pesticides. In that scenario they put a skirt or a tarp around the cage. Skirts are open at the bottom; tarps are closed at the bottom. They introduce into the water a pesticide. The most commonly used one in New Brunswick right now is something called Salmosan. There's also another treatment that's called Alphamax that has just been registered by PMRA about 10 days ago. Those are available for use.
In addition, it's not a chemical per se, but they can treat with hydrogen peroxide, which physically knocks the lice off the fish.
The more innovative way of treating these situations is with the use of what they call a well boat. Are you familiar with it? No. A well boat is a big boat with a well basin in it. They can take the fish out of the water, put them into the water on the boat, treat them with whatever it is, put them back into the water, contain the water, and deal with it appropriately. It's very much the way of the future in terms of addressing these issues, because it doesn't require putting the treatment directly into the water; it's done in a contained facility on the boat.
There are three of them operating in New Brunswick now, and that may well be the way of the future going forward. We'll see.
