Also headquartered in Norway, though it has major operations in Denmark and Florida, Atlantic Sapphire (ASA -32.24%) has one of the boldest strategies in the seafood industry.
The company is aiming to raise salmon in land-based fisheries. Typically, farmed fish like salmon are raised in marine net pens that allow seawater to circulate through them.
Atlantic Sapphire says it is the largest global land-based aquaculture company in the world, and it's innovating with its Bluehouse technology.
Bluehouse refers to its fisheries, where water is purified by state-of-the-art filtration systems, where the fish can swim against strong currents. The systems also help protect the fish from lice and wild fish diseases, and they allow the salmon to be farmed locally, making them fresher when brought to market.
The company opened its first Bluehouse in Denmark more than 10 years ago, but it's still a small company with $22.8 million in revenue in 2024. Revenue almost doubled in the first half of 2025 as it benefited from higher prices and better fish quality. It's targeting 25% growth in harvest volume to 5,400 tons, and sees similar growth in 2025 to 7,000 tons.
Its Bluehouse in Florida, which is currently under construction, is aiming for 220,000 tons of annual capacity.
