So there's quite a difference in the number of fish in that per cubic metre size.
Now, that leads me to my next question. Have there been any reports or studies done on tilapia from a fish health standpoint? But maybe more importantly, you talked about fish performance. What have been some of the issues for tilapia and those warm water species when you start getting up into that range?
I was saying to Mr. Kamp the other day that at 50 kilos per cubic metre, it's almost like we could walk across the tank on top of the fish. What are some of the challenges for fish performance?
