You definitely need cleaner water for freshwater prawns. Another problem is, they don't grow at the same rate. So you have to grade them by size and sex. I think they will need all-male or all-female populations as well on a large scale.
For Mexican white, they have done trials in the past at FF1. But I don't think they were succesful in growing them out to certain sizes. Perhaps not enough light. I think they have better quality shrimp now. If Tony can double the stocking density then you have a winner.
The experimental farm is something different. I don't think what they told us adds up. But they will grow big shrimp here for sure.
