Salmo salar

Towards the Digital Salmon: From a reactive to a pre-emptive research strategy in aquaculture (DigiSal)

Salmon farming in the future must navigate conflicting and shifting demands of sustainability, shifting feed prices, disease, and product quality. The industry needs to develop a flexible, integrated basis of knowledge for rapid response to new challenges. Project DigiSal will lay the foundations for a Digital Salmon: an ensemble of mathematical descriptions of salmon physiology, combining ...

Salmon farmed on modern feeds contains less of the healthy, long-chain fatty acids (EPA and DHA) than before. Up until the turn of the millennium, farmed salmon were fed fish oil as a replacement for their omega-3 rich natural prey. However, fish oil is now a scarce resource, and more than half of the fat in modern feeds comes from plant oils that are inexpensive, but devoid of long-chain omega-3 fatty acids. How can we increase the omega-3 content of salmon on sustainable feeds?

One option is ...

This is a sandbox where DigiSal members can learn to use the SEEK.

The SEEK is a web interface to a database of research "assets" organised in a hierarchical "ISA structure" (investigation-study-assay) [1]. These are further organised into projects and programmes.

• Programme = Overarching research theme (The Digital Salmon)
• Project = Research grant (DigiSal, GenoSysFat)
• Investigation = a particular biological process, phenomenon or thing ...

16S rRNA amplicon sequencing (Illumina MiSeq, V3-V4 region) to assess community structure.

Targeted proteomics for peptides related to fatty acid metabolism. Aim: Check which of these proteins we are able to detect in this experiment.

Lipidomic analysis by LC-MS of tissue samples from the GSF1 feed-switch experiment. Samples were analyzed at NTNU by Zdenka Bartosova and Per Bruheim.

There are two separate data files of lipid analysis in muscle and liver samples. Excel sheets contains both raw and normalised data of compounds abundance. Normalization to all compounds was used as a normalization method.

Atlantic salmon (Salmo salar) is the most valuable farmed fish globally and there is much interest in optimizing its genetics and rearing conditions for growth and feed efficiency. Marine feed ingredients must be replaced to meet global demand, with challenges for fish health and sustainability. Metabolic models can address this by connecting genomes to metabolism, which converts nutrients in the feed to energy and biomass, but such models are currently not available for major aquaculture species ...
