Well, they haven't been recommended by government, but they have been taking place nonetheless. A combination of actions by industry and the environmental movement and DFO this year monitored the effect of coordinated fallowing, which is effectively shutting down some of the channels to salmon farming.
There are still fish being grown in the archipelago year in and year out, but this coordinated treatment so that sea lice are reduced has been very effective. For the last five years sea lice numbers have been going down compared with earlier in the decade.
I was just trying to point out that sea lice are a parasite, and the concern about some kind of passage of disease is not founded, because the annual reports by the regulators have demonstrated this.
