Norwegian company Andfjord Salmon has reported continuing good biological conditions in the company’s first land-based pool at Kvalnes, with an outstanding salmon survival rate.
At the end of last month the company reported its salmon as having an average weight of 1.35kg, and the average weight of the smolt was 120 grams when released on 25th June this year. The survival rate remains high, currently at 98.70%.
‘Fish health, growth and survival rate are all interconnected. The foundation is strong biological conditions and a pool eco system that is as close as possible to the salmon’s natural habitat in the ocean outside Andøya,’ said Andfjord Salmon CEO Martin Rasmussen, commenting that some fish mortality is inevitable, with the weakest individuals removed from the pool, while the company also regularly extracts fish to conduct examinations of fish health.
Energy consumption at Andfjord Salmon’s Kvalnes pool continues to be low and well within the company’s target of 1 kwh/kg salmon produced.
‘The low energy consumption and associated costs underline the attractiveness of our flow-through system,’ Martin Rasmussen added.
Andfjord Salmon is using water from depths of approximately 40 meters below the sea surface for its flow-through technology solution. The water is substituted 15-17 times/24 hours. The company`s pools are square shaped with the intention of replicating a cross section of the Gulf Stream. At slaughter weight the density will be around 35-40 kg/cubic metre.
Andfjord Salmon expects to conduct first harvest mid-2023.
