Introducing a closed loop system for Tasmanian abalone farmers has been described as a radical proposal that could cost millions of dollars.The call for closed loop and effluent recycling for Tasmanian abalone farms has been made in the light of the discovery of ganglioneuritis in four Tasmanian abalone.The concern is that if a virus is found in a farm, the disease could be magnified and spread to the wild through effluent.Nick Savva from Australian Ocean Biotechnology, farms abalone at Clarence Point on the Tamar River and thinks it's likely that closed loop effluent systems could only be mandatory for abalone processors in the long term. "It would be a radical proposal for farms to go to complete recirc without any effluent or without complete sterilisation of effluent. As far as I'm aware there's no abalone farm in the world that works that way," he said."Mistakes can always happen and just guarding against the possibility of having a virus enter the farm in the first place is the best way to manage that."
