On the west coast there are specific rockfish conservation areas. They are not classified as MPAs under the Oceans Act, but effectively there are area-based restrictions that are designed to conserve areas of abundance of rockfish. I think the idea is good, but the issue is that in order to maintain their effectiveness there needs to be more monitoring and enforcement of that. Rockfish conservation areas are certainly supported by a range of angler groups, both commercial and recreational anglers, in order to maintain those fishery resources.
