But you can't grow them to sizes of 500g in just 14 weeks. LOL. You know they sink to the bottom if they get really big, so that would not be an efficient use of the tanks for SIAF. I think the best we can hope for is sizes 20/kg if even that. The final grow out stage is only 2 or 3 weeks.
Nevertheless, you get a really good price for sizes 20 or 30 /kg relative to 60/kg.
You can probably find more details in the filings about the sizes at different stages. But that doesn't mean they are applying the same strategy now. I know I'm pretty much on target.
So, the Giant prawns are sizes 110/kg after 5 or 6 weeks. They could sell as much as half of these (or more) after the first stage/ 6 weeks. So if we assume the average to be 90/kg for the Giant prawns, then we should be close.
