It has been. I've participated in scientific advisory reviews that DFO has sponsored or has organized around impacts of salmon aquaculture. There is an admission that the waste discharge from these farms has a small and potentially large ecological footprint. The question is how you manage waste that is basically dispersed into the environment. The aquatic medium is a very difficult environment in which to manage waste. We see that. We see from DFO's own reports that in the coastal zone, because of all the discharges, whether they're from the aquaculture industry or sewage plants or pulp and paper mills or any other kind of activity, we need to put into place the most strict and rigid measures to reduce that waste.
But what do you do at the end of a large net pen? You can't put a pipe on it. This is the problem. Because you can't put a pipe on it, it's very difficult to regulate that waste. If you had closed containment technology, there would be an end of pipe. There would be water coming in. If it's not a closed circulation system, you'd have a pipe coming out and you could measure exactly what's coming out of that pipe.
