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 ...

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.

Coastal zones and oceans constitute an essential fundament for Norway’s history as well as current economy, providing ecosystem services for fisheries, aquaculture, transport, tourism, and recreation. The petroleum activities in Norwegian waters have been crucial for Norway’s financial growth and in financing the Norwegian welfare state. As the pressure on the oceans continuously increases, both the petroleum industry and the seafood industries have acknowledged that awareness and actions are ...

Atlantic salmon is a main source of essential ω-3 long-chain polyunsaturated fatty acids (LC-PUFA) in many Western diets, especially eicosapentaenoic acid (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, DHA). However, farmed salmon meat now contains less healthy ω-3 fatty acids (FA) than before, due to the shift from marine to vegetable lipid feed sources. An important future aquaculture challenge is therefore to maintain a healthy and high EPA/DHA content when farmed salmon is fed a vegetable ...

This experiment is designed to pinpoint where in the metabolic network there are differences between salmon of different genetic families and on different diets. Analyses of this material will help inform feeding and breeding strategies.

Salmon will be reared on feeds with contrasting levels of very-long-chain polyunsaturated fatty acids. Then some fish will be crossed over to the other diet while others remain as controls. This perturbation of diet should provoke changes in omega-3 metabolism ...

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.

Fatty acids are extracted from samples and converted to fatty acid methyl esters (FAMEs) followed by separation by gas chromatography. This yields fatty acid profiles for each sample as percent of total FAME or milligram FAME per gram of biomass.

Samples of 40 45 50 55 60 mg were diluted in the same volume, then analysed. The resulting data describe the same tissue at different levels of dilution. From this we can devise some numerical post-processing that would make all samples "similar" based on the mass of tissue. This post-processing could then be applied to later samples given their mass.

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 ...

Three-minute presentation of the Digital Salmon research programme. Explains the societal challenge of sustainable fish feed, how systems biology helps speed up the search for better solutions, and the grand aim to build a library of mathematical models of salmon physiology linked to omics data.

Talk by Jon Olav Vik, Norwegian University of Life Sciences

The first Digital Salmon industry workshop raised awareness of the Digital Salmon vision and engaged major industry players in discussions on data sharing and reuse, guidelines and best practices for private-public collaboration. The workshop was a success, and a Digital Salmon working group was formed, comprising industry, academia and funding bodies. Its first task is to develop a white paper to be presented to the industry in summer of 2020.

Our 2018 DigiSal project meeting is held as a satellite meeting of Digital Life 2018 (https://digitallifenorway.org/arrangementer/digitallife-2018).

Most of DS18 will be spent on breakout sessions to work on upcoming publications. Task leaders will prepare:

• Abstracts to DLN18. (Deadline was 15 Feb.) Presenting DigiSal progress here rather than at DS18 frees up time for the paper preparation sessions.

• Identify two papers in preparation, which will be worked on at DS18: Title, first and ...
