I'll answer that one. I believe you're referring to the Marine Stewardship Council MSC certification.
Basically, for other people in the room, that's a third party certification body that comes in to look at a specific fishery. I can only talk to lobster because our Prince Edward Island fishery is certified for lobster. Basically, they look at the number of traps, the length of the fishing season, the types of traps that are used, how the biomass is protected or sustained, and a whole number of things. They audit both the harvesting side and the processing side, and it is basically a consumer-driven certification in that the organization certifies that the fishery is, in fact, sustainable.
There are annual audits that are conducted, and then by every fifth year you have to be recertified. They initially grant a five-year certification, and then you would have to be recertified in year four to have it continue.
