This study is for the purpose of rebuilding the lobster stocks and sustainably managing the future harvest of primarily the Northern Zone rock lobster fishery. Over the past 10 years the total catch of the zone has been steadily decreasing to the present all time low.
The industry has in this time had a complete change of management plans, going from input controls to output restrictions, in the form of individual transferable quota. Since the shift to quota management 7 years ago the total allowable catch has been annually reduced until 2009, hoping to leave more breeding stock in the sea.
The aim of my study has been to network with fishermen, fisheries managers and scientists from the northern hemisphere, where the lobster fishery has survived since the early 1800’s, and in places like Nova Scotia which are having record catches.
Travelling through Maine and Canada’s east coast where in excess of 25% of the worlds annual lobster catch is caught gave me the opportunity to meet and share knowledge with significant stake holders in the industry. The UK and Ireland also have a similar length history of lobster fishing, but their stock levels are significantly lower. This made for an interesting look at different methods of management and fisheries control.
One of the major differences between the North American fisheries and the South Australian fishery is the amount of scientific research being done. Canada and the U.S. have numerous research bodies and facilities, with the fishing industry and the community (through sponsorship) funding many of these.
One of the most encouraging projects that has just been started in Canada is the study of DNA profiles in lobster. The benefits of being able to trace where a lobster egg hatches, and the path the paurulas take before settling to the sea floor could be invaluable to rebuilding stock levels in lobster fisheries all around the world.
Significant change in the way forward could come in trap design. This is something that has not been changed in the northern zone since moving from input controls when a standard trap was necessary for management purposes. Now that quota management is in place a more efficient trap would mean less time the traps are in the water, therefore less by-catch and lower mortality rates of trapped lobster. This would result in lower running costs for fishermen and more fish being left in the sea.
Another key difference between our industries is public perception. The North American fisheries have strong community support and public understanding of the value of the fishing industry. They are using some brilliant educational and promotional tools that could be well utilized by the Australian industry, to give a better understanding of the fisherman’s commitment to responsible stewardship of the marine resources.
After talking to lobster fishermen and fisheries managers in other sectors of the world, South Australia’s rock lobster industry needs to better promote its self to the general public. It could be said much damage was done in the 60’s and 70’s with the style of fishing compared to the present. Awareness of the environment and marine eco system preservation is very much a part of today’s fishing practice.
Although there is always room for improvement in management plans, the Northern Zones current plan is more detailed than any I saw in the Northern Hemisphere, which I found encouraging.
