Certainly, productivity is the focus. In fact, section 6.1 of Bill C-38, of the amended Fisheries Act, says that the purpose of the fisheries protection provisions is to support the “sustainability and ongoing productivity” of Canada's commercial, recreational, and aboriginal fisheries.
Habitat is a crucial element of that, but it is not the only element of that. We now have new tools to address other threats to fisheries, such as aquatic invasive species, and to take other approaches around productivity. But productivity, as you point out, is the focus of the fisheries protection provisions.
