Andfjord Salmon’s technology provides robust barriers to limit escape. The company started working with Norconsult and DNV in 2021 to meet the requirements for escape safety in NS 9416 Landbased aquaculture farms for fish. The latest status report gave Andfjord Salmon the highest score in terms of the prevention of fish
Fish health and welfare
Ensuring good health and welfare is both an ethical responsibility and the most important factor in achieving good growth, higher quality, and lower costs.
Fish health and welfare, such as protecting the fish from unnecessary stress and impact, are at the core of Andfjord Salmon’s innovation. Continuous water flow from deep waters ensures that our salmon live in an environment where the presence of salmon lice and poisonous algae is close to non-existent. In 2022, Andfjord Salmon has continued to carry out extensive planning and testing to ensure optimal fish health and welfare. The company’s fish welfare measures are comprehensive and focus on all aspects of the farming value chain, including feed and nutrition, respiration, thermal regulation, water quality, hygiene, disease management, behaviour control and social contact and rest, and the company’s overall goal is to mimic the salmon’s living conditions in the sea as much as possible.
On 25 June 2022, Andfjord Salmon released approximately 200,000 smolt at an average weight of 120 grams in the company’s first land-based pool at Kvalnes, Andøya. Due to strong biological performance, the average weight of the salmon reached 1 kilogram in November 2022 – well ahead of the late December 2022 forecast. The survival rate stands an industry leading 98.9 per cent, four months after the smolt was released. Water quality and thermal regulation. An optimised living environment with the best water quality is a key basis for good fish health and a high survival rate. In 2021, Andfjord Salmon verified the laminar water flow technology at the first pool at Kvalnes, which confirmed that the company was able to recreate wild salmon’s natural habit on land and offer the salmon the best possible living environment. Now that the company is in production and is striving to ensure continuous and optimal fish welfare, Andfjord Salmon regularly examines the water quality, including monitoring the presence of pathogens.
The company is also in the process of setting up a complete sensor system based on fish welfare indicators made by Fishwell to monitor, control, and optimise the water quality and living environment of the fish in the pool. The patented Andfjord Salmon flow-through pool system supplies a continuous flow of 100% seawater. As water is pumped from a depth of 40 meters, water temperature is considerably more stable than what would be expected at corresponding depths in net pens and is follows seasonal patterns in ambient water temperature. During the first six months (approximately) of production, over 60% of daily temperature readings were in the range 10–16°C, which is considered optimal for sea farmed salmon.
