From what I know, they are not groing any prawns at AF1 any more. But for sure the margins has improved over the years as they learn how to optimize the systems.
One other factor that will be a big challenge at the mega farm is to train enough workers as they build out the farm.
There is no coincidence that they are using AF1 for testing out new species, they have the most experienced workers.
I would belive that the main reason why they are planing to build ODRAS at the mega farm location is that that type of farming is much more alike to traditional open dirt pond farming. This way they get a smother transition for the new crew, they start at he ODRAS and learn the basics of RAS, then they advance to the APRAS indoor tanks.
There will be many many challenges going forward, but once they "get it right", the production will ramp up fast.
