These are aquaculture sites that were originally salmon sites. The amendment was to allow these salmon sites to grow more than one species, and to allow them to put seaweeds and mussels. They're commercial salmon sites, to which we gradually add more mussel rafts and more seaweed rafts.
But I also think we need to completely change our perspective. We try to manage at the site level too much, with imaginary boundaries that nutrients don't recognize—only humans put buoys in water. Nutrients move differently. As a matter of fact, it would be much better to have management at the bay level area instead of site management, because the nutrients affect more than one site. We have to think about commercial things, but at the level of a bay. This means that the seaweeds can be a little more downstream than the shellfish, and we could have previous salmon sites becoming seaweed sites. We have to think about more than simply restricting our area to the limit between four buoys.
