The logical position to take on this is that the closer to the marketplace that fish farms can be created, the less the cost of transportation of the product to the customer. Sadly, if the system of closed containment was the only system acceptable to us all, provincially and federally, then there would be very little, or fewer and fewer, opportunities to employ the people in the areas that are far away from the transportation routes and from the areas in which the product is being consumed.
Plain logic says that if you're going to do something like this and spend millions of dollars in creating an on-land system, that land system is going to be as close to the marketplace as possible, which takes away the opportunities from the people who otherwise would be employed, if they were living in an isolated area and utilizing the natural conditions in that area to produce the product.
