In fishes, most studies focus on species of commercial interest. Sticklebacks often colonize new habitats by starting with a small founder population which, thus, suffers a high risk of inbreeding. However, little is known about the degree of inbreed- ing depression of sticklebacks’ life-history traits like fertilization success or hatching and survival rate. Furthermore, there is a general lack of knowledge about the impact of inbreed- ing on sexually selected traits like males’ breeding coloration. In our study, one generation of inbreeding by brother–sister mating of wild-caught, anadromous sticklebacks significantly lowered the fertilization and hatching success of eggs. This effect was intensified by a second generation of inbreeding. Furthermore, fewer inbred individuals reached and survived
