Again, this is where science and technology are going to help move us along.
With respect to sea lice, for instance, there is very good evidence to suggest that sea lice infestation happens in the top two or three metres of water. Sea lice have a very well-known life cycle. Again and again the science is suggesting that submerging the fish during that time can have a potential mitigating impact.
It also comes to the flow of water through the cages. The iCage has been optimized to maximize the flow of water through the cages, which keeps the oxygen flowing through the cages and takes away the metabolites. In theory—you've talked to people such as Mr. Robertson and many others—that should lead to potentially healthier fish, with maybe a little bit healthier immune systems and such, in certain situations.
