I'll take a crack at that. It's hard to generalize, for the most part. Maybe the easiest one to answer is the bowhead, because it's such a broadly distributed animal. These are very large whales, and they range over a very large part of the Arctic. Generally, that stock now is considered to be in fairly good shape. Our recent estimates were considerably better overall than what had previously been thought. It's probably a combination of change in the stock and change in our ability to pull together a good picture over a wide area. Nevertheless, it's reasonably good news, and it's conservatively harvested, so I think that's fairly good.
With regard to narwhal, it's a species where there is some concern, but we've done a lot of work within the department and with our co-management partners over the last couple of years to put together a more robust management program and a science program to support it. The driving factor here is CITES, the Convention on International Trade in Endangered Species. This species is listed on appendix 2, which means that we need to be able to look at the harvest and certify in a sense that they are sustainable before products could be exported. It doesn't affect domestic use, but foreign export. As David mentioned earlier, there is an export market for narwhal tusks. We've been doing a lot of work with our co-management partners in the Arctic to get those fisheries into shape and be able to show that they are being sustainably harvested at current levels.
Beluga really varies. There are a number of stocks of beluga, and they vary from being not in bad shape to being in quite bad shape, depending on where you are. All of these are being monitored. There are different management plans, as David explained earlier, in those different areas with the appropriate level of control.
Ringed seal is a bit of a challenge. It's endemic everywhere. We don't, quite frankly, have a good monitoring program for ringed seal. We don't have the sense that there's a big issue with ringed seal, but we would be hard pressed, to be honest, to bring forward a good quantitative analysis on that right now.
