Given they have a sustainable tonnage (granted that is a big if) I would rather see the tonnage spread over the years than the lake getting clobbered 2 out of every 4. Because what could happen is you get a bad spawn conditions the years after the big haul you could colapse the lake if the main forage fish has major drops.
Also markets would be esier to maintain with a smaller but constant supply. the reason you don't see Alberta whitefish in stupidstore is they want to run a special next Tuesday they want 50,000 lbs for all of western Canada, they support nothing local, except maybe beef and grain but that's another story.
I agree harvest need to be sustainable, bi catch needs to be minimized, but give me a natural fisher over fish farms all the way.
