FIS - Companies & Products - Collaboration and Expertise Drive Success in Deep Farming

Proven experience shows that submersible farming systems can improve fish welfare, reduce sea lice exposure and deliver predictable operations when technology, routines and expertise work together.

Deep farming is still a relatively new operating method for many fish farmers. By keeping fish submerged at greater depths, producers can reduce exposure to sea lice while benefiting from more stable environmental conditions. Experience from early adopters, however, shows that deep farming works – and that it can be implemented predictably when the right expertise , routines and operational support are in place.

For AKVA group , deep farming is about exactly this: applying practical experience and maintaining close operational follow-up. As reported by Anne Oma in AKVA Group News , the company's approach is rooted in lessons learned directly from commercial operations.

Sinkaberg leads the way

Sinkaberg is currently the company with the most extensive experience in deep farming. Today,100%of its fish are operated either indeep farming systemsor through other forms of shielding, making deep farming a natural part of everyday operations across the organization.

“For us, this is not about trying something new, but about further developing something we know works,” says Tronn-Ove Øren , Project Manager for Development at Sinkaberg .

Documented operational experience

Operational data shows that conditions at depth are generally more stable, with fewer external forces acting on the structures. At the same time, deep farming places high demands on precise rigging and well-established routines . So far, results have been very positive.

Growth , feed conversion ratio (FCR) and production efficiency remain at normal levels. The most significant difference is the sharply reduced need for delousing . With fewer treatments, fish experience less stress – delivering clear benefits for fish welfare .

However, conditions can vary between sites. In some locations, local current patterns may cause mixing of the water column, pushing sea lice deeper and reducing the overall effect. Experience shows that it is the interaction between technology , site conditions and operations that ultimately determines performance.

The learning curve is steepest during start-up, but efficiency improves as routines become established.

400 pens deployed and counting

To date, around 400 Nautilus units from AKVA group have been deployed in collaboration with leading salmon farmers. The solution is also being used commercially by Ode AS in deep farming of cod . In total, more than 25 deep farming production cycles have now been harvested.

These projects have built a strong knowledge base that AKVA group now uses to support customers in their daily operations .

“Deep farming can deliver both higher survival rates and improved fish welfare. We are talking about fish that have remained at depth and have not been handled from stocking to harvest. This shows that the potential is significant,” says Svein-Gustav Sinkaberg , CEO of Sinkaberg .

Planning creates control

Experience also shows that robust planning and routines are essential to success.

“Deep farming can feel more demanding in the early stages. Once routines are in place, we see that operations can be carried out efficiently,” says Arnstein Hosaas , CIO at AKVA group .

Deep farming facilities can be installed within standard mooring frameworks , without the need for specially adapted service vessels – provided that operational procedures are well established.

Collaboration enables better operations

The development of deep farming has been driven by close collaboration between fish farmers and suppliers. Continuous adjustments to equipment and working methods have gradually simplified operations and increased predictability.

Deep farming continues to evolve through ongoing cooperation between AKVA group and fish farmers, with technology tested directly in commercial conditions. This work forms part of the company's contribution to more sustainable aquaculture under the vision of Pioneering a better future .

“We improve with every stocking. It is about learning as we go, making adjustments and building expertise throughout the entire operations organization,” says Øren .

Investing in deep farming for cod

Ode , which has now completed its first commercial cod harvest in submersible Nautilus pens , also highlights operational experience as a key success factor.

“Deep farming provides stable conditions for the fish and better production control. Experience from the first commercial harvest shows good welfare and high fish quality. It takes time to master a new operating method, but with experience the work becomes easier,” says Andor Bjerke , Operations Manager at Ode .

Submersible pens are seen as a natural step towards improving fish welfare , sustainability and product quality . Ode is now planning to stock Nautilus pens at two new sites in 2026 .

Confidence built over time

Both Sinkaberg and Ode describe deep farming as a distinct way of operating aquaculture – not merely a technical add-on. As experience grows and routines mature, uncertainty is reduced and confidence increases, reinforcing deep farming as a viable and scalable production method for the future.

协作与专业能力推动深水养殖取得成功

经验证明，只要技术、操作流程和专业经验协同发挥作用，沉水式养殖系统就能够提升鱼类福利、降低海虱暴露，并实现可预测、稳定的生产运营。

对许多养殖企业而言，深水养殖仍然是一种较新的运营方式。通过将鱼类养殖在更深的水层中，可以减少海虱暴露，并获得更加稳定的环境条件。先行企业的实践经验表明，这一解决方案是可行的，并且在具备专业能力、成熟流程和运营支持的前提下，可以实现可预测的落地实施。

对AKVA group而言，深水养殖的核心在于将实践经验应用于生产，并对日常运营进行密切跟进。正如Anne Oma在AKVA Group News中所报道的那样，该公司的方法建立在商业化运营的真实经验基础之上。

Sinkaberg 走在行业前列

Sinkaberg是目前在深水养殖方面经验最为丰富的企业。如今，该公司100%的鱼类要么采用深水养殖系统，要么使用其他形式的防护方案，使深水养殖成为整个组织日常运营的自然组成部分。

“对我们来说，这并不是在尝试新事物，而是在进一步发展一种已经被证明有效的方法。”Sinkaberg 发展项目经理 Tronn-Ove Øren表示。

经验证的运营经验

运营数据显示，在较深水层中，结构所受的外部作用力更小，环境条件更加稳定。同时，深水养殖对精准系泊和成熟的操作流程提出了更高要求。目前为止，整体结果非常积极。

生长速度、饲料转化率（FCR）和生产效率均保持在正常水平。最显著的变化在于，去虱处理需求大幅降低。处理次数的减少降低了鱼类的应激反应，为鱼类福利带来了明显改善。

当然，不同养殖场之间的条件存在差异。在某些区域，局部水流条件可能导致水体混合，使海虱进入更深水层，从而影响整体效果。

经验表明，最终效果取决于技术、场址条件与运营方式之间的相互作用。启动阶段的学习曲线最为陡峭，而一旦流程成熟，运营效率便会明显提升。

已部署 400 个网箱

迄今为止，AKVA group已与多家领先的三文鱼养殖企业合作，部署了约 400 个 Nautilus 沉水式网箱。此外，该技术也被Ode用于鳕鱼的商业化深水养殖。目前已完成并收获了 25 个以上的深水养殖生产周期。

这些项目积累的经验，构成了AKVA group如今在日常运营中为客户提供支持的重要专业基础。

“Deep-water aquaculture can achieve both higher survival rates and better fish welfare. We are referring to fish that remain in deep water with minimal human intervention from stocking to harvest. This clearly demonstrates the enormous potential of this technology,” said Svein-Gustav Sinkaberg, CEO of Sinkaberg .

Planning brings control

Practice has also shown that successful implementation of deep-water aquaculture requires a sound operating procedure .

“Deep-water aquaculture may seem more challenging in the initial stages. But once the processes are established, operations become efficient and smooth,” said Arnstein Hosaas, Chief Information Officer of AKVA group .

Once the operating procedures are mature, deep-sea aquaculture facilities can be installed within standard mooring systems without the need for specially modified service vessels .

Collaboration drives better operations

The development of deep-sea aquaculture stems from close cooperation between aquaculture companies and suppliers . Through continuous adjustments to equipment and operating methods , operational processes have been gradually simplified, and predictability has been significantly improved.

Through close collaboration with aquaculture companies, AKVA group continuously tests and optimizes its technologies in real-world production environments. This is also a significant contribution the company makes to sustainable aquaculture under its vision of "Pioneering a better future ."

“We continuously improve with each deployment. It’s a process of learning as we go, constantly adjusting, and accumulating expertise across the entire operations organization,” Øren said.

Investing in deep-sea aquaculture for cod production

Ode has completed its first commercial cod production cycle using submersible Nautilus cages , and also emphasizes the crucial role that operational experience played in the process.

“Deep-water aquaculture provides a stable environment for fish and improves production controllability. The first commercial harvest demonstrated good fish welfare and high-quality products. Mastering a new operating method takes time, but with experience, the work becomes easier,” said Andor Bjerke, Ode’s Operations Manager .

Submersible cages are seen as a natural step toward improving fish welfare , sustainability , and product quality . Ode plans to deploy Nautilus cages at two new fish farms in 2026 .

Confidence is built over time

Sinkaberg and Ode agree that deep-sea aquaculture is not only a technological solution, but also a completely new aquaculture operation model . As experience and processes accumulate, uncertainty gradually decreases and confidence increases, making deep-sea aquaculture a future-oriented, scalable production method.
