Claim: The National Pollutant Inventory (which is a database of Australian pollution emissions) omitted the mandatory reporting of the aquaculture industry in Spencer Gulf Australia where the southern bluefin tuna and yellowtail kingfish aquaculture are main contributors of nitrogenous nutrient pollution to the marine environment.
Evidence: In 2007, Environment Ministers voted against the lifting of the reporting exemption for aquaculture, despite the review receiving 12 submissions supporting the recommendation, and 5 opposing it. The National Pollutant Inventory (NPI) is a database of Australian pollution emissions managed by the Australian Commonwealth, State and Territory Governments. This omission of the aquaculture industry from mandatory reporting is significant for Spencer Gulf, South Australia. In this region, southern bluefin tuna and yellowtail kingfish sea-cage aquaculture are the two largest industrial contributors of nitrogenous nutrient pollution to the marine environment.
