AquaGen performs initially a traditional family-based selection with information from more than 12 measured traits of the broodstock. When the top brood candidates are selected on this level, we are taking samples for DNA analysis to find genetic markers (QTL’s) associated with different traits. This QTL selection is more precise than family selection and the best individuals from the best families are selected in this final round. We call this a double selection since broodstock undergo selection by two different methods that complement and reinforce each other.
The table below provides an overview of the traits we have found QTL’s for, in which products they are included and what documentation that exists for the various traits.
