Genetisk resistens mot vintersår i atlantisk laks

Offentlig prosjektsammendrag

Moritella has been shown to have small to moderate, albeit significant, heritability under controlled challenge testing. Furthermore, winter ulcers in field outbreaks have in some cases been estimated with moderate heritability and with a favourable correlation to resistance under challenge testing. The goal of this project is to perform controlled challenge testing of the AquaGen breeding nucleus and use these data in genomic selection. Secondly, we want to validate the efficacy of this selection under field conditions (at the AquaGen sea site(s), in designed field testing in an exposed area, and by product testing in customer sites. Finally, we also want to test heritability of ability for wound healing, as this may be linked with ability to avoid moritella and other skin infections under natural conditions.
