During our Macquarie Harbour cruise we stopped for a couple of minutes at the salmon farms. Those dark discs that you can see in the photos are the tops of fish cages. In the bottom photo you can see the fish in one cage being fed. The spray is full of fish food and whatever medicines are needed. Naturally the gulls try to grab as much as they can. Because these farms are close to the Franklin-Gordon Wilderness they have been a source of some anger and concern, in case the farming impacts the World Heritage area. At present there is a limit on the number of fish that can be farmed and the effects on the heritage area is being closely monitored. It is not just gulls that the farmers have to cope with. The big danger is when they have to go diving to inspect the netting and repair any damage. The local seals and sea lions are keen to get at the fish inside the netting and have attacked several of the divers. I don't think it is a good job for small bears.
