Sanford, New Zealand's largest seafood company, is applying to build five small open ocean salmon farms in what it dubs 'Project South,' according to a document found on the company's website.

The project can potentially yield 25,000 metric tons of King salmon in Southland; up from current levels of only 3,800 metric tons, Ted Culley, aquaculture manager at Sanford, told What's On Invers.
