As I said in my remarks, the current open net-pen systems occur in a variety of geographic areas. Mr. Storey has been talking about looking at the carrying capacity of the specific environment in which you're operating. These open net-pen systems have organic loading associated with them. In some cases it's not a problem and it's difficult to demonstrate any kind of impact. In other cases, because of the ecology you're dealing with, organic loading will occur and it's possible to demonstrate a loss of biodiversity.
The answer may not necessarily be moving straight toward closed containment, but you may be able to mitigate those effects by including biological filtration. That will be described by Dr. Chopin here in this IMTA piece. This biological infiltration comes in the form of shellfish, plants, and a whole series of things, and they're very site-specific. You may have to go back and apply a different technological platform, like the one you're looking at, with a different system that forces you to think about balancing your production with the carrying capacity of the environment.
There may be circumstances where none of those things are appropriate, and moving the net-pen system to land in tanks is appropriate. I think a comment was made earlier about that. To do that you need to have the right set of circumstances, including access to power, which would mean very limited application in what's happening today with open net-pen systems.
