Lice count data from controlled challenge tests show large genetic variation in resistance to salmon lice in salmon and no unfavourable genetic correlations to other traits. Selection for increased resistance will over time reduce the need for delousing. How fast depending on the weight given to this trait in the breeding objective. Predictions show that selection for only increased resistance will reduce lice count per fish with 24 % per generation or 75 % over five generations.
Goal:
To obtain more reliable estimate of the genetic variation in resistance to L. salmonis in Atlantic salmon.
Subgoals
• To investigate the magnitude of genetic correlation between resistance to the salmon lice and other economically important production traits in Atlantic salmon;
• To investigate if biomarkers and genetic markers can be found that can be used as predictors and thus indirect selection criteria for increased resistance to L. salmonis in Atlantic salmon;
• To investigate if the counting of the number of lice per fish can be automated using digital image analysis.
