We updated the conservation objectives. In the examination of closures that had been in place historically under the Fisheries Act, some of the areas were areas that we knew right away did not meet the criteria for biodiversity purposes. They're useful as fisheries management measures—for example, protecting a particular stock—but just protecting a stock doesn't necessarily protect biodiversity. There have to be other elements to it, and one of those elements is the benthic habitat.
By combining those two objectives and updating the purpose of the closure, we were able to say, yes, this does count towards biodiversity.
The reason that we would look at the existing areas is partly taking into consideration the economic impact on the fishing industry. If it was an area where they had traditionally not been fishing, then by expanding the conservation objectives but maintaining the boundaries, we were having less of an economic effect than if we were to pursue a closure in a different area where there was fishing activity.
