I'll comment quickly on that and let the other guys comment as well.
I had a lunch in 2014 with a Chinese corporation that operates a line of grocery stores. Basically, they came to me offering to buy a prawn licence and boat for me because prawns and shrimp are in huge demand and they needed more access. They saw Canada as having quite a large, valuable stock. They also commented to me that over the past 12 months, they had bought 10 shrimp trawl licences in Canada.
I can't speak on any other specifics, but that is one specific. I actually had lunch with the people and that's what they told me.
