Salmon are being allowed back into a fish farm in Macquarie Harbour in Tasmania, Australia, which was destocked last year due to environmental degradation, reports ABC News.

Lease operator Tassal was ordered to remove all fish from the Franklin site, the closest to the World Heritage Area (WHA) border, after tests found a significant decline in the number and range of organisms.

Petuna, which now operates the Franklin lease together with the state's biggest producer Tassal, said the Environment Protection Authority (EPA) has now given its go-ahead to restock.
