Chilean, Norwegian Aquaculture: Stocking Density Metrics
June 11th, 2008 by AndrewTHE Chilean Government’s emergency salmon committee, convened in late April. Amongst other things the committee is calling for a comprehensive study to determine exactly how much salmon production Chilean waters can handle.
Chilean salmon farms produce, on average, 25 kilos per cubic metre, according to the Santiago-based environmental NGO Fudación Terram. In Norway, the world’s leading farmed salmon producer, the concentration is significantly lower: 15 kilos per cubic metre, it says.
Benjamin Witte’s Patagonian Times article provides further details on the Committee’s challenges and some hard hitting opinion from Terram.
What stocking densities are achievable with other species? Any insights on Barramundi available Greg?
