The developers of Norwegian firm Nekst's subsea cage project say the system can prevent mortality from algae blooms, a potentially major boon for the industry in light of the most recent crisis.

The company received approvals for two development license applications to build HavLiljen, a subsea cage solution designed to speed up salmon production and reduce biological impacts.

Producing deeper underwater can effectively eliminate the need for sea lice treatments, Nekst Founder Martin Ramsdal told IntraFish.

The company applied for 16 licenses to build the land-based fish farming complex last year, which would produce about 20 million large-sized smolt for grow-out (around 20,000 metric tons).
