I'm from Moncton, so I know that area really well.
The Northumberland Strait was once one of the most productive marine systems on the planet. It's a shallow water system with a lot of benthic production and, at least in my lifetime, we've seen dramatic changes in the kinds of fisheries that have occurred in the Northumberland Strait. There used to be a massive herring fishery. We exported herring all over the world from there. We don't now. At best, there's an artisanal fishery in herring.
We've flipped the system. It's very productive for lobsters now, but it's not that productive for much else. We've changed the system, and we're taking advantage of that highly changed system, but it's a long way from where it was in terms of being highly productive.
I think your question is, how could an MPA fix that system? That's a good question. I don't think there's a really simple answer, but I think that fisheries management, as has been pointed out, is an imperfect science, and it has to be somewhat experimental. We could set up an MPA in that area to see what would happen in that system, and you would have to carefully consider how to do it. I know a bunch of fishermen from there, and there's a lot of interest amongst the fishermen in doing that, in setting up an MPA to see what would happen.
