LetSea is Norway's largest private experimental and research centre for aquaculture, with infrastructure from small tanks to full-scale cages. The company farms mainly Atlantic salmon, Atlantic cod, and lumpfish. It has nine locations distributed in northern Norway and has its head office located at Sandnessjøen, surrounded by a mountain range called the seven sisters.
Atlantic salmon (Salmo salar) is an anadromous salmonid species widely distributed in the North Atlantic Ocean. The juveniles reside in freshwater for their early development and grow to smolt that undertakes downstream migration to the ocean to do feeding migration for several years. This fish is an extremely important commercial species; therefore, its sustainable farming is vital. LetSea has excellent experience working with Atlantic salmon and offers controlled research trials.
In the DIGIRAS project, LetSea is involved in mapping the microbial population, investigating the biological water quality, and examining fish behaviour during the production of Atlantic salmon grown in RAS. Both fish and environmental samples are collected. For fish samples, mucus from the fish skin, gills, and gut are taken. For environmental samples, water from the tanks and the source is collected; in addition to that, biofilm from the tanks and biofilter is taken to monitor the microbial development over time. For the first sampling regime, one cohort was targeted and followed for six months, with samples collected each month. Furthermore, LetSea will utilize its unique infrastructure to set up and run micro-RAS systems with camera technology to test different fish behaviour.

Norwegian Fish Farms Tydal (NFFT) is a SME farming Arctic charr in RAS and FTS. It is situated in picturesque Tydal municipality between Sylan and Fongen mountain range in mid-Norway, close to the Swedish border.
Arctic charr (Salvenlius alpinus) is a salmonid species which is naturally occurring in surrounding cold rivers, where it has adapted to harsh and challenging environment after the polar ice caps have moved from today's land thousands years ago. Arctic charr can be of migratory or non-migratory life-style. Migratory is alternating between fresh and seawater (anadroumous), whereas, non-migratory remains for the whole life cycle in the freshwater. Sustainable and conscious source of Charr for the market can be found in small farms at many locations in Norway, NFFT being one of them.

For the purpose of DIGIRAS project and mapping of microbial community dynamics during production of Artic charr, screening of the RAS is performed. Samples from tank water, tank wall biofilm, biofilter biofilm and source water are collected. Additionally, samples from fish skin mucus, fish gill mucus and gut are taken.
For the first sampling three different cohorts of fish were targeted, ranging from 35g to 500g. These cohorts will be followed up for 6 months with samplings performed once a month. |

Job vacancy- Postodoctoral fellow within DIGIRAS
|
Department of Production Animal Medicine, Section for Animal Welfare, Epidemiology and Community Medicine at NMBU announces a vacancy for a postdoctoral fellow in aquaculture and epidemiology with a duration of 3 years.
We are looking for a person with an interest in both fish health and epidemiology. The position will be divided between two different projects. In one project, field trials will be carried out which the candidate will coordinate. In the second project, the candidate will be associated with the project «DIGIRAS», here NMBU's role is to link chemical and biological water quality data to clinically relevant fish health and production data. Common ground for both projects are coordination of sample collection, data processing and analysis. For more information about the position and application follow the link: www.jobbnorge.no/ledige-stillinger/stilling/199061/postdoktor-innen-epidemiologi-akvakultur?fbclid=IwAR30UzUrCoQCW0EcBatDRBdIzZzdTL5Z-SW0KNHBE4gu5oiuGWHTbGG9r-E |
