In a couple of different ways. Typically, during the spawn-on-kelp season, while the kelp is in the ponds, the herring are spawning, and so forth, we will do surveys in various locations where the potential to remove the product is possible. In other words, the herring are there, the kelp are present. So we will survey those areas periodically.
The second thing we do.... This product usually has to go through some sort of plant; it has to be processed in some sort of way along the lines I've described. So we will look at various plant operations to see whether they're actually storing spawn on kelp, and if they are, if that can be traced back to a valid licence holder, and it's legitimate versus product that's not legitimate.
These are the two principal ways we use to try to stay on top of whether there's black market product showing up.
