Mowi farms, processes, and sells Atlantic salmon to customers around the world.
Mowi is the world's biggest Atlantic salmon farmer. If you've eaten smoked salmon on a bagel in New York, bought salmon fillets at a supermarket in Paris, or ordered a salmon sushi roll in Tokyo, there's a decent chance the fish came from Mowi. The company breeds salmon, raises them in nets in cold coastal waters, harvests them, and then processes and sells them in many forms — whole fish, fillets, smoked salmon, burgers, and sushi-ready portions.
Here's the basic problem Mowi solves. Salmon don't grow on trees, and wild stocks can't come close to meeting global demand. So Mowi raises them: young salmon hatch in freshwater tanks, then get moved to open-sea pens off Norway, Scotland, Chile, Canada, and other coasts, where they grow for roughly a year to 18 months before harvest. It's farming, but on the ocean, and it's trickier than it sounds — fish get sick, sea lice are a constant nuisance, storms damage equipment, and rules about how much salmon each site can produce are strict. Mowi's scale is its edge: volume spreads the fixed costs of feed, boats, and processing plants, and it runs its own feed operations and sales network so it captures more of the value chain than a pure farmer would. The money works like this: hotels, restaurants, and supermarkets — plus wholesalers and distributors — pay Mowi for salmon, and Mowi's profit hinges on the gap between what salmon fetch per kilo and what it costs to feed and raise them. Feed is the single biggest cost, which is why Mowi bought feed operations of its own. Salmon prices swing wildly with supply and demand, so Mowi's earnings bounce around with them; a good year for prices can be great, and a glut of fish — say, from a big harvest season or weak demand — can crush margins fast. Then there's the fish itself: salmon farming gets criticized over sea lice treatments, escapes, and the environmental footprint of feed, and regulators in Norway in particular have tightened rules and hit producers with a "resource rent" tax on the profits from farming Norway's coastal waters, a real cost that shapes where Mowi invests. Sea lice and disease outbreaks remain an ongoing operational headache across the industry.
Mowi was long known as Marine Harvest and renamed itself Mowi in 2019, but the business underneath is the same salmon machine: it's a global company with Norwegian roots, listed in Oslo with a secondary listing in New York. It pays a substantial dividend and runs one of the world's most recognizable seafood brands, with products sold from the freezer aisle to the sushi counter. The simple version: Mowi is a factory that turns fish feed and cold seawater into protein the world wants, and its fortunes ride on salmon prices, farming conditions, and how tight the regulators keep the leash.
