fish farms

I know it's been debated before but the latest scientific research
states that sea lice found in huge concentrations near fish farms are responsible forup to 95% mortality rate in juvenile pink and chum.
this is a confirmed scientific fact.

I remember reading something about Salmon ranching. I believe the idea was to have a hatchery, let the salmon go out to sea and then harvest them when they get back (of course keeping some for brood stock).

I suppose the reasons why big business wouldn't be drawn to it are:

1) Can't use genetically modified fish.
2) Would have to use Pacific salmon.
3) Factors would be out of their control (such as ocean survival, predation)

Some reasons to be for it would be:

1) Wouldn't need to feed them all the way to harvest.
2) Could probably market them as "wild".
3) Wouldn't cause the water pollution that net reared salmon do.
4) Sea lice would not be an issue more than it is in a "normal" marine environment.

Does anyone know of an operating system like this? I know they've tried it, but I think most have gone under.
