As far as I'm aware there have been no new fish farms in the last couple of years.
I should emphasize that I'm not involved in the aquaculture industry whatsoever. I have absolutely no investment in it. I've carefully separated myself from any activity that could be seen as being supportive or benefiting in some way from the aquaculture industry. I think it's worth clearing up that point right at the beginning. I should have included it in my brief.
I believe that the aquaculture people themselves have the statistics on it. Neil may have some details on it that I'm not aware of. I don't follow it day by day or hour by hour, the way that Neil has probably kept an eye on it.
I'll ask Neil to elaborate on my response.
