That's a great question. There are a number of reasons.
The researchers more than the university per se are interested. Several of us are really interested in what limits the performance of fish. We do a lot of work studying how animals adapt to different environments, and the possibilities are quite amazing.
Something like closed containment is interesting because here you have a system where you can manipulate the environment a fish lives in and look at the effect of that environmental manipulation on the animal, and why certain things limit performance. For example, in the case of salinity, we're very much interested in the evolution of salinity tolerance and how fish move from fresh water to sea water, and that kind of thing. We're also interested in why performance is ultimately limited at some salinity in different species.
There's a basic research component that we're interested in, but the other thing is that it's a way of applying our knowledge to something that's of direct relevance to the public. So I think that most of us believe that sustainable aquaculture, or any way we can increase the sustainability of aquaculture, is a good thing.
The role of aquaculture—sorry did you...?
