Egg size and alevin length prior to the onset of exogenous feeding in wild/farmed crosses.

<p>A) Figgjo/Mowi cross C2011, B) Figgjo/Mowi cross C2012, C) Figgjo/Mowi cross C2013 and D) Vosso/SalmoBreed cross C2013. DD: degree-days from fertilisation to termination prior to the onset of exogenous feeding. Families are sorted in groups containing their respective maternal and paternal half-sibling, i.e., three families per group in Figure A and D, and four families per groups in Figure B and C. Wild/farmed hybrids are named by the origin of their maternal × paternal half-siblings. Maternal half-siblings emerging from farmed eggs are illustrated by dotted lines, while maternal half-siblings emerging from wild eggs are illustrated by solid lines. In C2011, F₁ hybrid family 4 and 6 are paternal half-siblings to Figgjo family 22, while F₁ hybrid family 8 and 10 are paternal half-siblings to Figgjo family 23. In addition, Figgjo family 26 and 27 is paternal half-siblings to F₁ hybrid family 14. Boxes show the median (thick line), mean (+), 1^st and 3^rd quartiles (lower and upper boundary) and the lower and upper extreme (whiskers).
