In today ?s breeding programs genetic improvement for these traits is sought through selection for growth until harvest and survival in specific disease challenge tests. In this project using fish from 100 families we will record growth and total survival in the entire seawater period as well as specific causes of mortality, and discriminate between fish with optimal and sub-optimal growth. We will use existing and advanced disease diagnostic methods for assigning specific causes of mortality and obtained growth curves of individual through repeat recordings of their size. We will quantify the genetic variation of mortalities during the early period of sea transfer, and estimate the genetic correlation between early survival at sea and smoltification status of their sibs. In addition we will estimate the genetic variation in specific and total survival at sea, and the genetic correlation of survival at sea with survival from controlled challenge tests with specific diseases. Furthermore, based on the growth curves of individuals we will estimate the genetic variation in healthy and subclinical growth, and the genetic correlation of these traits with survival and smoltification status. A genome wide association study will be undertaken for the studied traits with genotypes generated from a 57K SNP array. Finally, we aim to link good microbiota data to survival and growth of healthy and sub-clinical fish. The project will increase our limited knowledge on the genetic variation in survival at sea
