As I pointed out, I started during its infancy, over 20 years ago. We were a bunch of dreamers who thought we were going to feed the masses and change the world by offering farmed seafood. At the time, there was a strong learning curve. We learned a lot about the rights and wrongs and what was correct and wasn't correct.
Again, that was 20 years ago. For example, what would you do with fish that had naturally died within the pens? Nobody really knew what to do with them at the time. It wasn't until afterwards that permits and actual regulations started and there were specifics on how to discard that product.
The industry has changed dramatically over the last 20 years. It has become more international in scope. We've gained a lot of knowledge on farming practices from Norway, Chile, and other countries.
My concerns way back when were predation—how to deal with seals—and the impact on the benthic environment. If you're in a site that doesn't have heavy flush, you could get a buildup of feed and fecal matter underneath the pens, and that is not healthy for fish in general. It's not healthy for the marine ecosystem.
Obviously, there was the issue of escape. I don't think there has been any clear science-based research to prove that alternate species of Atlantic salmon have been able to interact and reproduce with our natural wild stock. There is the issue of predation and certain river systems being taken over if it got out of hand. At this point in time, it never has, so it's never become an issue.
Certainly there are other issues that are of concern now. There are biohazard issues, food safety issues, and the debate about sea lice, of course. Really, I'm not a scientist. At this point in time, it's not for me to say. I don't have enough research to gain an opinion or to make a comment on that.
