We modelled at a peak density of about 35 kilos per cubic metre. It's our experience that the fish have done very well.
Peter referred to cortisol earlier. We did some comparable stress tests from the facility at Cedar where we were growing them at 42 kilos per cubic metre and compared that to net cage farms. The scientist doing the work was not able to find any significant difference in cortisol levels between the fish in the Cedar facility and the net cages he was looking at. That's a piece of interest.
I also think that fish find their own densities. We observed the fish in our tanks moving both horizontally and vertically through the water column. They seemed to find their comfort zones. I believe that as long as we're providing the right amount of refreshed water and oxygen systems, they don't experience that much stress.
We've had a lot of comments on the fish condition in our system. They're a really robust fish. They look very healthy and behave very healthily. So far, I don't think that's an issue.
