If I remember correctly, the open net-pen systems were about $2,500 per tonne, and the closed containment systems were somewhere between $9,000 and $10,000. Can anybody correct me on that? I think it was three to four times more expensive from open net-pen to closed containment, if I remember correctly. Following that model and assumptions, we estimate that the investment would be somewhere in the order of $3,000 per tonne versus the $2,500 cost of the open net-pen system.
