Overview of the experimental design. The five step experimental procedure: 1. Synchronized single-strain parent populations of L. salmonis are produced from three source populations of different origin. 2. Couples of virgin lice in individual fish-tanks produce full sibling families 3. A mixture of copepodids from selected louse families common-garden infected into four replicate tanks. 4. Sampled lice exposed to EB, evaluated and sorted. 5. Family affiliations are resolved by individual genotyping of offspring, sorted by trial outcome, and parents. Full arrows: Preadult II female and adult male lice, in pairs of two (
) or a group of many (
) lice. Full black arrows (
) denotes dead lice. Dashed arrows: Egg strings from one (
) or many (
) female lice. Dotted arrows: Copepodids originating from one (
) or many (
) female lice.
