I will give one answer first and then pass it to Andy.
In fact, land-based aquaculture is a huge industry around the world right now, but it has only newly moved to the opportunities with salmon. There are other species—tilapia and barramundi are examples—that have been well developed and are in huge production around the world.
What we're testing out now is salmon. Technically, it works very well. Salmon are grown in closed containment on land and, in the first part of their life stage, in hatcheries, so there's nothing new there. What's new is making sure that with the current price of salmon and the markets this all fits together. It may take a few years for that to develop in a way that gives a full opportunity.
