Dr. McKenzie, I want to thank you for the information you gave us, and particularly for the comments you made about animal welfare issues, and so on.
You said there is documentation or studies to show optimal densities for fish health and welfare, and 17 to 22 kilograms per cubic metre, I think, was the number you used. Can you provide us with some studies or documentation, something we can understand, that gives us a bit more information on that?
