I'd say it basically depends on the landings, as far as I can see. There are area scientific studies going on. I know when I was in DFO we had a fairly big project going in southwest Nova Scotia. I don't know whether that one is still going through, but it might be. We had another one in Prince Edward Island.
Really, what DFO does is that they look at landings and make most of their decisions, a posteriori, on what's going on. Other than that and some basic lobster biology that they do science on, those are the things that they're really working out.
My hypothesis back in 1979 was that the egg drift, the larval drift of lobsters, through the Canso causeway and down the eastern coast of Nova Scotia, was cut off when the causeway was built. When they cut that off, the lobster stock collapsed from normal fishing. There just was no recruitment, so it was down in the stocks.
