| Lisätietoa: | Abstract Understanding the drivers of evolution is a fundamental aim in biology. However, identifying the evolutionary impacts of human activities is challenging because of lack of temporal data and limited knowledge of the genetic basis of most traits. Here, we identify the drivers of evolution toward earlier age at maturity in Atlantic salmon via two types of fisheries-induced evolution acting in opposing directions: an indirect effect linked with harvest of a salmon prey species (capelin) at sea (selection against late maturation), and a direct effect due to net fishing in the river (selection against early maturation). As capelin are harvested as an aquaculture feed protein source, we hereby determine an indirect path by which salmon aquaculture may influence wild salmon populations. |
