At first glance, a quota system for fishing seems to make sense. The catch set annually by scientists is "shared" among those fishing, divided into units or quotas and initially allocated. Overfishing and the threat of a fisheries collapse are given as the reasons for capping catches with quota on commercial fisheries. Others see it as privatisation of fisheries by stealth.
Now the Victorian government is talking "off the record" and "behind the scenes", about placing a quota on recreational fishfolk for southern bluefin tuna. There have also been strong hints on the Department of Primary Industry website.
