Arctic Charr Breeding

The Icelandic Arctic charr breeding programme has been initiated in 1989 based on individuals from 13 different Icelandic populations and is running since. The first selected cohort was generated in 1992. The breeding station is situated in Hólar, Iceland and run by Hólar University.

In the past, fish have been selected for increased growth rate using both between- and within-family selection and for late sexual maturation using between-family selection. Recently, late sexual maturation is also selected for using within family selection.

More recently, fish are additionally selected for reduced deformity rates and increased survival rates under production conditions using between-family selection.

We are currently investigating whether we can increase egg quality traits, such as egg size and egg survival rate. These traits may be influnced by either, or a mix of, environmental effects (growing conditions and practices), direct genetic effects (genetic effects inherited from both parents that affect egg quality traits), or by maternal genetic effects (direct genetic effects of both grandparents on maternal traits whose expression affect egg quality traits).

In addition, we are currently conducting research on how to implement a feasible quantification method that allows selecting for increased resistance to bacteria that cause furunculosis.

Future research may investigate why deformity rates are elevated in only some cohorts and under only some environmental conditions.
