 Nutreco's initial attempt to further expand into the fish farming sector by acquiring the seafood arm of Norsk Hydro was blocked on the recommendation of the United Kingdom Competition Commission in late 2000, but the deal was approved in March 2001 after Nutreco agreed not to acquire Hydro Seafood's Scottish assets.Nutreco retained the name Marine Harvest for the unit's fish farming operations, and established interests in the emerging farmed cod, halibut, yellowtail and barramundi markets.In May 2005, Nutreco merged its fish-farming operations with the salmon, trout, halibut, tilapia, cod, sturgeon and caviar businesses of Stolt-Nielsen, creating a new stand-alone company, again named Marine Harvest.
