Will deep farming change the way we farm fish? Meet us at Aqua Nor

AKVA group invites you to presentations and demonstrations focused on deep farming during Aqua Nor – the world’s largest aquaculture technology exhibition. The event takes place in Trondheim from 19–21 August and gathers professionals, developers, and customers from around the world.

Ten years ago, AKVA group began developing deep farming – a submerged farming concept. In collaboration with Sinkaberg and research communities, the technology was first tested in the Atlantis project and later evolved into what is now known as the Nautilus concept. Key results include fewer lice treatments, improved fish welfare, and more stable operating conditions.

“After ten years of development, deep farming is no longer just a concept – it’s a proven solution. We look forward to demonstrating how the technology works in practice and discussing the next steps,” says Arnstein Hosaas, Innovation Director at AKVA group.

The Nautilus solution from AKVA group has been widely deployed for salmon and, this spring, also for trout. The technology is now being applied to cod as well. In collaboration with Ode, the world’s first commercial deep-water cod farming facility was launched at Alida in Volda. At Aqua Nor 2025, AKVA group will present insights from the development and look ahead to the next steps in deep farming.

Deep farming sessions – Stand D-340 (2nd floor)

Over the course of three exhibition days, AKVA group will host short presentations on deep farming, covering topics such as biology, technology, and feeding. The sessions will be led by experts with hands-on experience in the development and use of the technology.

“Deep farming opens new opportunities for combining stable production with strong fish welfare. At Aqua Nor, we’ll share how environmental and biological conditions influence outcomes below the surface,” says Merete Gisvold Sandberg, Global Solutions Manager.

“Currents and waves play a major role in how the pens must be designed and operated. We’ll share our experience and demonstrate how we adapt the solution to each site,” says Magnus Røsseland Bollmann, Global Solutions Manager at AKVA group.

“Feeding must always be adjusted to the environment and fish behavior. In deep farming, it’s about understanding how the fish behave and how we can deliver the right feed, in the right place, at the right time,” says Odin Rørvik, R&D Manager.

Live demonstration at Skansen

Just a five-minute walk from the main exhibition area, AKVA group will present its new feed barge and demonstrate equipment for sea-based farming at Skansen.

The feed barge holds 500 tonnes of feed and features an efficient feeding machine with angled placement of selectors and strain relief on the silo deck for optimal operations. Photo: AKVA group

Close to the expert community

Aqua Nor offers the chance to meet developers, researchers, and farmers with real-world experience using deep farming. AKVA group will share hands-on insights and discuss the future of aquaculture – where technology and biology go hand in hand.

Welcome to stand D-340 and the Skansen area.
