We've been taking a close look at this and the relationship between aquaculture and marine protected areas. We believe there are better choices that can be made by the industry in relation to some of the points that Daniel Pauly has already made.
Farming higher level species and feeding fish to fish doesn't make much sense, but smaller-scale aquaculture involving bivalves and other things may have some compatibility with some categories of marine protected areas.
We need to get a better understanding and a better application of that relationship.
