Why they keep referring to AF5 is also a bit of a mystery. But I think I understand now...
One building at AF4 can grow a max of 800MT Vannamei. I think they are using the 2nd building (with the shallow tanks) for broodstock, not sure. So that's only $4M profit at best annually, from Vannamei indoor.
But, they are using the ponds as well. 400 mu for AF4 and another 400 mu for AF5. That's 2x26 hectares. Some of it has been converted to 2G/3G ODRAS. Perhaps most of it?
2x26 hectares is > 5,000MT. Quite substantial. And quite profitable since TRW owns 100%.
Interesting.
