Verlasso’s salmon farm in Herradura, Patagonia has received independent certification for sustainable aquaculture practices by Det Norske Veritas (DNV).
The Herradura farm joins the company’s La Lanca and Quilque Sur farms which were certified in July of this year and November 2011, respectively.
DNV validated Verlasso’s differentiating and dramatically reduced 1:1 fish-in, fish-out ratio for fish oil and fishmeal and low average pen density of 12 kilograms per metric ton.
The average fish-in, fish-out ratio across all salmon farms is about four pounds of feeder fish to produce one pound of salmon. Verlasso currently uses one pound of feeder fish to produce one pound of salmon. Their calculation is guided by the Aquaculture Stewardship Council's salmon standards.
