First of all, in terms of some of the types of protection for corals, sponges, reefs, and those sorts of things, if you're destroying those areas with certain types of fishing or any type of activity, it's not good for the fishery. There's absolutely no question. I think all stakeholders would agree with that.
With respect to having specific areas set aside and then increasing the pressure in other areas, in neighbouring areas, the theory—and there are different views on this—is that by protecting a certain area you're really going to allow it to grow and it's going to populate, because fish tend to move around. It's going to populate those other areas, and there's going to be a benefit from that. MPAs are fairly new. For some, there's documentation that shows it does work. Others are saying that if it's a well-managed fishery, it doesn't make that big a difference.
We are going to have to keep all of those things in mind to ensure that there is an ongoing robust fishery in Canada, but that we are applying the proper protection. It's not an easy thing.
Tom, did you want add something?
