Location and history
Lumarine Sleneset in Lurøy municipality was founded in 2014-2015 by Dan Kristian Larssen, and is known to be one of Norway’s most modern cleaner fish facilities. The company was originally named Atlantic Lumpus AS. This was the first RAS facility in the world for cleaner fish, and is a pioneer within high-intensity saltwater RAS. Atlantic Lumpus AS was acquired by Lumarine AS in July 2019.
The facility at Sleneset comprises six separate departments, each with its own water treatment system, used exclusively since its foundation for lumpfish production. The facility started production of live feed in the spring of 2021, and introduced the first yolk sac larvae. The facility is to be converted into a marine facility for fry.
- Hatchery (flow-through)
- Start feed (flow-through)
- Growth (RAS)
- R&D department 1, R&D department 2 and R&D department 3 (RAS)
Production line: Incubation (HATCHERY) -> larvae (START FEED) -> fry (SILO GROWTH) -> vaccination and lumpfish ready for delivery (GROWTH TANK)
Hatchery/Start feed: Fertilised roe are introduced for incubation for around 300 degree days before they hatch in start feed tanks. Newly hatched larvae are well-developed and live off the yolk sac for around two days, before being weaned on to solid feed. The fish are screened here for any pathogens before the larvae are sorted and transferred to silos in the growth department, where they are kept until they are approx. 0.6 grams.
Silo – metamorphosis: Once the larvae have been moved to silos, the fish metamorphose from larvae to fry. The fry are left undisturbed until they weigh approx. 4 grams, when they are sorted and moved into larger tanks in the growth department.
Tank – On-growing: After being sorted from the silos, the fry remain in the on-growing department until they are vaccinated, at a weight of approx. 10 grams. After vaccination, the lumpfish are moved to a tank where they remain for minimum 500 day-degrees until they are ready for delivery, at an approx. weight of 30-50 grams, depending on customer requirements. Before being released to the sea, the fish are screened for any pathogens, according to customer demand.
One of the R&D departments has been converted for production of live feed, and the two other R&D departments have been converted for production of ballan wrasse larvae.
