The weirs are ingenious in their simplicity. As we know if we're coast dwellers, the tide rises and falls every six hours. As the tide rises, those rock weirs catch the salmon. They come in and they get stuck in there and our people used to go and get them.
We had a very sophisticated governance system. The chief was the one who did the oversight in managing the salmon. That was one example of how this could be done.
Also, the Coast Salish on the Salish Sea had the reef net fishing also for weirs. There were weirs in the rivers that would guide the salmon into a certain area and they'd go and pick out specific pieces of salmon. That ancient technology and that sustainable technology still exists today.
