Too bad on a number of counts. I'll bet it could be recycled as a valuable
fertilizer. Can anybody tell me what that 600 mt rating for the big Sea
Pen cages means? Is it 600,000 tons (of Atlantic salmon) per year per
100,000 cu. meters? Any idea how much waste would accummulate in mt's from
that many fish?
You see what I'm getting at? If the yields here are so high, maybe the
industry could afford the cost of closed containment. Especially if we can
get some by-products out of it like fish fertilizer.
