Norwegian company plans to build one of the world’s largest land-based salmon farms in Belfast, a project that would create 60 jobs within two years and up to 140 once it is completed, according to the company’s chief executive officer. Nordic Aquafarms, an international developer of land-based aquaculture, has signed agreements to purchase 40 acres on the outskirts of the city and plans an initial investment of $150 million in the project. The company is currently building the largest salmon farm in Europe, but Heim said that facility would be dwarfed by the one planned for Belfast, which would be roughly five times the size.
