What I'd like to bring to your attention is the historical outlawing of the fish weir. The fish weir is a very important kind of technology that is still available to us. It was used by our ancestors to responsibly manage ocean and particularly salmon resources. These kinds of source-based fishery activities were outlawed and replaced by interception-based fishing, which has created a lot of problems.
With marine protected areas, if we were going to create a Nuu-chah-nulth marine protected area, for example, we would continue to foster and enable the more responsible fishery activities, such as the fish weir.
