Submerged pens

In submerged farming, pens are lowered to depths of 30–50 meters. This approach helps avoid surface-level challenges such as lice, algae blooms, waves, and harsh weather. Submerged pens are equipped with specialized feeding, monitoring, and oxygen-supply systems – often referred to as air domes – to maintain optimal fish health and growth at depth.
At the forefront of submerged pen technology from the start

Breaking the mold with the pioneers

The first commercial-scale trials with submerged pens began in 2019, and Aquabyte was there from the start. Our system played a key role in gathering critical data during these pioneering projects, helping farmers and researchers understand how fish perform at depth. At Aquabyte, we’re proud to have been part of breaking the mold alongside companies that are transforming aquaculture technology.

Engineered for submerged operation

Designed for submerged pens, the Hammerhead combines a compact form, self-cleaning technology, and optional salinity and oxygen sensors — reducing maintenance needs, minimizing diver inspections, and lowering technical risk. Its small size makes installation easy, while its construction, specially engineered for operating at great depths, makes the Hammerhead a class-leading camera for submerged pens.

From pioneering to industry standard

Trusted in the majority of submerged pens

Over the years, submerged farming has evolved from experimental trials into a proven, established production method – offering solutions to surface-level challenges like sea lice, algae blooms, and harsh weather. Today, our technology is trusted in the majority of submerged pens, delivering accurate, real-time insights that enable farmers to decrease lice pressure, improve welfare, and maximize operational efficiency.
