I guess I needed to know more regarding raising Prawns.. I know in Alberta you can get aquaculture licenses for raising prawns. What I didn't realize its that it might be harder to do in dugouts in Alberta. It requires attendance, water and habitat controls and feeding to raise the prawns. Trout you stock and don't worry about so much. Prawns can live in water from 12C to 40 C and you harvest in the same year so winter isn't a factor. Further south they harvest 1200 lbs. per acre in shallow ponds.
In Alberta there is one farm capable of producing 60,000 lbs of prawns. It is a high tech aqua operation in above ground buildings. At Strathmore. Not producing since covid.
