Mr. Stringer is right that this is a very difficult question to answer explicitly. One way to answer it might be from more of a general perspective.
Mr. Stringer has already alluded to the three phases, to the research, development, and commercialization continuum, if you will. Certainly if we look generally at aquaculture development--let's say the development of salmon aquaculture in Canada from the late 1970s, or the development of some other new species, such as cod aquaculture--it's not unusual to see a time cycle of 10 to 20 years in the research to development to commercialization continuum.
So from the perspective of closed containment-type systems, as Mr. Stringer said, we're probably into the development or pre-commercialization phase right now. It will certainly be a number of years before we're able to get to a stage where we're able to undertake the studies required to demonstrate the technology and show it's biologically feasible, and also to be able collectively to demonstrate that the level of risk, from an economic and environmental and biological perspective, is low enough to warrant the type of investment required for industry to take this to the commercialization phase.
