After 800,000 salmon died at a Homestead fish farm, animal activists are asking that government officials investigate the farm for animal cruelty and file criminal charges against the company's CEO. Atlantic Sapphire is a Norwegian industrial fish-farming company with operations in Denmark and Homestead that bills itself as the "largest global onshore aquaculture company in the world." At its 160-acre facility in Homestead, the company raises about 10,000 tons of salmon per year, with plans to expand over the next ten years to 220,000 tons — a figure that represents more than 40 percent of current U.S. salmon consumption. As U.S. demand rises for salmon, a so-called superfood that's rich in protein, aquaculture is emerging as the seafood industry's answer to overfishing. Land-based salmon farms like the one in Homestead say they can meet that demand while draining fewer environmental resources than other methods of salmon production, such as the "net pen" method, in which salmon are kept in nets out in chilly ocean water.
