The rockfish conservation areas are actually quite small. I'm sure Sean can elaborate on this, but they are included in that 1%, all the rockfish conservation areas. There's not a huge area that's protected that is uncounted at this point. I wanted to make that point clear.
In terms of how much biomass, there is no optimal number. We could spend a lot of time going into ecosystem theory here, but the biomass is based upon the productivity in the system, the perturbations that happen to that system, and how long it has been around. That's one of the reasons you want to have some areas that you don't fish, so you know how these systems function. They can act as reference points so you can calculate how much fish you're going to take out of the system without doing significant injury. You can calculate these reference limits, for example.
