Very quickly, early indications are that coordinated area management with chemical treatment and fallowing appears to reduce sea lice numbers. It looks like it's having the desired effect. I think that's a more fundamental change. Moving the farms away from wild salmon migration routes would be far more effective and would relieve the tenuous reliance on chemical treatment. This should be done in the context of spatial planning, whereby areas should be set aside for wild salmon ecosystems where they're not exposed to these risks.
