Just real quick - I've heard Antarctica mentioned a couple times but isn't it true that the Patagonia toothfish and the bluefin tuna are both completely devastated stocks? So how can that be sustainable? (and I'm assuming that if somewhere is using ecosystem based management appropriately, then fisheries would be sustainable).
This is tangential to the article I'm writing, so I was just curious. But now I'm ever more curious...

The Commission to the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR) regulates fishing and other resource-utilization activities in the Southern Ocean. (Patagonian toothfish, Antarctic toothfish & southern bluefin tuna are some of the lucrative fisheries in the Southern Ocean.) Assessments by the Working Group on Ecosystem Monitoring and Management, the Working Group on Fish Stock Assessment and CCAMLRs Scientific Committee form the basis of the regulatory measures, and they are developed in accordance with an ecosystem approach to management that acknowledges the interlinked and complex ecological systems of the Southern Ocean biomes. The conservation principles that guide CCAMLRs management include prevention of decrease in the size of any harvested population to levels below those which ensure its stable recruitment [ ]; maintenance of the ecological relati! onships between harvested, dependent and related populations of Antarctic marine living resources and the restoration of depleted populations [ ]; and prevention of change(s) or minimisation of the risk of change(s) in the marine ecosystem which are not potentially reversible over two or three decades, taking into account the state of available knowledge of the direct and indirect impact of harvesting, the effect of the introduction of alien species, the effects of associated activities on the marine ecosystem and of the effects of environmental changes, with the aim of making possible the sustained conservation of Antarctic marine living resources. The incorporation of these principles into CCAMLRs management practices is integral to CCAMLRs aim to follow both a precautionary approach and an ecosystem approach to regulation of the harvesting of Antarctic marine living resources. In keeping with these principles, the CCAMLR Ecosystem Monitoring Program (CEMP) was created in 1984 to (i) detect and record significant changes in critical components of the ecosystem, to serve as a basis for the conservation of Antarctic marine living resources and (ii) to distinguish between changes due to harvesting of commercial species and changes due to environmental variability, both physical and biological. The Working Group on Ecosystem Monitoring and Management coordinates the efforts of the CEMP. Standard methods for data collection and analysis were first established in 1987 and revised in 1997. Via these methods, CCAMLR has collected and analyzed ecosystem data from numerous sites, species and other parameters. The CCAMLR Catch Documentation Scheme (CDS) for Antarctic toothfish is an example of application of an ecosystem approach and a precautionary approach to governance of living resources. The CDS aims to (i) monitor the international toothfish trade (ii) identify the origins of toothfish imports or exports, (iii) determine whether toothfish catches have been made in accordance with CCAMLR conservation measures, and (iv) gather catch data for the scientific evaluation of toothfish stocks. This program promotes responsible fishing techniques and accountability in the commercial fishing industry. The CDS operates in conjunction with CCAMLR monitoring programs for krill, finfish and sea birds in order to provide a more comprehensive view of the ecosystem health. Additionally, survey data (from fisheries and fishery-independent surveys) and strategic modeling are methods utilized by the CCAMLR Scientific Committee to assess ecosystem status. If you want more info, I'd be happy to send you the references for the above info or the paper (from which the above text is culled... sorry if it's still a bit too much for this forum). The CCAMLR website is well-written, and you'll find a wealth of information there. For other regional fisheries management organizations, some good information can be found at the following sites: http://www.chathamhouse.org.uk/research/eedp/current_projects/rfmo/ h ttp://www.illegal-fishing.info/item_single.php?item=document&item_id=171&app roach_id=8http://www.sams.ac.uk/research/ecology/research/research-themes/pr operity-from-marine-ecosystems Best of luck with your research on this. I hope to be able to read your findings!
