You talked about some different operations, and certainly we know there are closed containment systems, other than those for salmon, that are quite successful. There are also some pilot projects for salmon closed containment, and we've heard from those as well.
There is a difference between the types of fin fish, whether they're salmon or whether they are in fact different species of fish. You're saying it's mainly a compatibility issue, with open-net and other fishing operations such as lobster in the same area? Is it about compatibility, because of the perception of contaminants?
