If I could just add to that briefly, I think it's a good case study. Because the fishery was on 100% of the fishing grounds the stock collapsed to a low level that did not allow for recovery immediately. We actually had a talk by Jeff Hutchings on this very topic last night here. He won the Huntsman award this year. He pointed out there's a strong correlation between how far the species is depleted and how quickly it recovers, and that there is a threshold at about 10% of the biomass. If it goes below that threshold it may not recover or it may take a very long time to recover. If we stop to impact it before 10%, it may quickly recover and there's general evidence for that.
I want to point out that if we had insured this incredibly valuable asset through a network of marine protected areas at the time, that collapse wouldn't have been as complete and recovery would most likely have been much quicker because part of the stock would have been protected in a protected area.
