That's a really good question.
I'm involved, and have been involved, with a program that actually compares the Barents Sea with the Newfoundland shelf to look at the differences in response. One of the things that happened off Norway was that the stock collapse, or what they call a collapse, in comparison to ours was not a collapse. In their collapse, the stock went down to about 20% to 30% of peak. There was this huge biomass that was there to rebuild the stock afterwards.
The other thing that happens in the Barents Sea is they are much warmer than we are. The system is influenced by the Gulf Stream, so the water temperatures are four to six degrees higher than ours, even on the bottom. There's a real difference in the production potential, because we're dealing with cold-blooded animals, and their metabolic rate is related to the temperature and the environment. It's typical to see a doubling of metabolic rates for a 10-degree change in temperature.
