In northern Europe, the parasite has been occasionally observed, but has not been documented to cause increased m ortalities until a few years ago. Since 2011, AGD has however been the major cause of salmon mortality in Ireland and Scotland, and has been observed in Norway, probably because of increased water temperature. AGD is treated by freshwater or H2O2 baths, w hich adds production costs and stress to the fish. Selective breeding for AGD resistance is currently performed in Australia and is to date the only known method to reduce the AGD problem over time. To breed for AGD resistance in Norway, Scotland and Irel and it is necessary to obtain genetic parameters for AGD resistance in north east Atlantic salmon, which will be obtained in this project. Through testing the same families for AGD resistance both in a controlled challenge test and under field conditions in Ireland will show whether the challenge test gives a good prediction of field resistance. Breeding for AGD resistance in Norway is dependent on such a controlled test, as the natural outbreaks occur with irregular intervals. Further, 1000 fish from the se trials will be SNP genotyped for 2 purposes; estimation of genomic breeding values and QTL search. Including genomic information in the breeding value estimation, either by detecting major QTL or by genomic selection could increase the efficiency of th e breeding program through within family selection. To gain insight about the mechanisms involved in AGD resistance, 60 fish will be RNA sequenced and included in a gene expression study. The results from this project will give the involved partners knowl edge on how to efficiently test and implement selection for increased AGD resistance in a breeding program for Atlantic salmon.
