Thank you, Mr. Chair, and welcome to our guests.
Your colleagues last week gave a great presentation. They were very informative. I knew absolutely nothing about aquaculture before that time. I know significantly more now, but still not nearly enough. I know a little bit about sea lamprey control, because in Sault Ste. Marie last week, during my constituency week, I visited the Department of Fisheries and Oceans and had a very good tour. I'll have some nice pictures for you folks down the road very soon.
It's my understanding that in terms of return on equity, there are only two types that have shown a positive return. One is the net pen and the other is a recirculating aquaculture system, as it's referred to.
It's my understanding that there are different types of RAS systems. I wonder if you could elaborate on the difference between the AquaOptima RAS technology and the RAS system evaluated in the feasibility study of closed containment options for B.C. I'm trying to get an understanding of the differences between RAS systems, most specifically in terms of capital costs, and in terms of the different returns on investment, or returns on equity. What differences would have an impact?
