Assessing potential technologies for closed-containment saltwater salmon aquaculture
Jun 19, 2008 — A review by Fisheries and Oceans Canada (DFO)of over 40 closed-containment systems from around the world found that none was producing exclusively adult Atlantic salmon and that many previous attempts to do so had failed. Reasons for failure were numerous and were often interrelated. These reasons included but were not limited to mechanical breakdown, poor fish performance, management failure, declines in market price and inadequate financing
Five types of production systems were described and examined: (a) conventional net pen; (b) floating, closed-confinement systems with rigid walls; (c) floating, closed-confinement systems with flexible walls; (d) land-based flow-through system; and, (e) a land-based reuse system.
