Biography Tone-Kari K. Østbye
I work with muscle quality and nutrition in Atlantic salmon focusing on muscle deformity, muscle structural and muscle regulatory factors, oxidative stress, apoptosis, and fatty acid metabolism. I make use of techniques like cell culturing, quantitative PCR, microarray, cloning, immunocytochemistry, and Western blotting. I received a master degree in biotechnology from the University in Tromsø and the master thesis in medical genetics from the University Hospital North Norway. My doctoral degree within molecular fish biology and muscle regulatory factors in Atlantic salmon is from Nofima Marin (formerly Institute of Aquaculture Research) and the Norwegian University of Life Sciences.

2001
1. January 2021 – 31. December 2024
Do Pacific salmon species carry a secret they could share with Atlantic salmon? What is it in the genes that make these relatives of Atlantic salmon less susceptible to lice? Researchers will now find the answers to these questions, using the gene editing method CRISPR-Cas9.
1. March 2019 – 28. February 2023
Identify and validate candidate genes for CMS resistance in Atlantic salmon through state-of-the-art gene editing.
1. January 2017 – 31. December 2020
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.
1. January 2017 – 31. December 2019
Fish health and growth are affected by gastrointestinal processes. This includes feed intake regulation, digestion and absorption of nutrients, barrier function and gut microbiota.
This project will study how feed composition affects physiological mechanisms that control the pigmentation of salmon muscle and contribute to the development of a feed that secure good and predictable pigmentation of farmed salmon.
