BALANCE

Significance of the interaction between nutrition and genetics for the development of metabolic imbalance in Atlantic salmon

 Breeding and genetics    Fish health    Nutrition and feed technology    Production biology  

In BALANCE we will increase the basic understanding of how nutrients in the feed, in combination with genetic background, affect the occurrence of metabolically induced health and quality problems in Atlantic salmon.

Time:1. January 2017 – 31. December 2020
Financed by: The Research Council of Norway
Commissioner:Nofima

Knowledge from the project will make the aquaculture industry better equipped to design a composition of fish feed and breeding program that ensures the health and quality of farmed fish in modern production.

Several recent studies suggest that the nutritional composition of the feed is of great importance for the salmon’s robustness, the presence of melanin stains in muscle, and reduced deposition of astaxanthin in muscle. Salmon fed diets with high fat levels in combination with 70-80% plant ingredients (low levels of EPA + DHA) have also been shown to increase the risk of fat accumulation in internal organs such as the gut, liver and heart. Similarly, in previous NFR projects (207621, 244200) we have shown that the genetic background of the salmon is of great importance for how the composition of the feed affects the muscle quality and health of the salmon.

In BALANCE, we will combine the use of new techniques in transcriptome, metabolism and gene editing with traditional physiological and biochemical analyzes to increase the basic understanding of how nutrients such as amino acids, fatty acids and astaxanthin in the feed affect the occurrence of metabolically induced health and quality problems in Atlantic salmon.
