On a recent trip to Port Lincoln for a patient, I had occasion to fly over a bunch of these rings on the water. I had only recently become aware of them and it was interesting to see modern tuna fishing in action. Because the local tuna stocks were in decline several years ago, and there were strong indications that the fishing was no longer sustainable, some clever folks got together to set up these floating nets and stocking them with tuna. They feed them three times a day and monitor their health for the entire time until they are big enough to "harvest". With the price of tuna being around $25.00 a kilo in the market, I guess it must be working for them.
