Wayatinah and Florentine hatcheries (owned by Salmon Enterprise of Tasmania
Pty Ltd - SALTAS) produce brood stock of Atlantic salmon (Salmo Salar)

were taken every two weeks of the effluent, the receiving waters upstream, and
downstream of the farm - these were tested for nutrients and other critical
environmental parameters. Additional samples were collected from these sites
once per month after the fish-holding tanks had been flushed for cleaning
purposes.
Effluent quality from the two facilities was reasonably good and the levels
of the measured parameters generally met the curren
