Servicing and operating expenditures are higher in offshore waters. Whilst most salmon operations are tucked in secured coves near shore, the waves above O’Hanlon’s cages can strike twenty toes or more. But all of that speeding h2o is The purpose: He’s making use of dilution to stay away from air pollution and condition. Don't just are his cages stocked in a fraction in the density of The standard salmon farm, and also, sitting down in deep h2o, they’re continuously currently being flushed by The present as well as waves.
