Atlantic Sapphire knocked off its perch as world's most valuable land-based salmon farmer

There's a new land-based salmon farming giant in town.

The share price of Salmon Evolution, a company backed in part by Korean food giant Dongwon and US agri-giant Cargill, has risen over 30 percent in the past week, and market watchers think there's even more upside to come.

The company, whose project outside Molde, Norway, reached a key milestone last week with fresh seawater flowing into the company's first test tanks, is now worth NOK 3.294
