Triploid (sterile) farmed Atlantic salmon males attempt to spawn with wild females

Genetic interaction between farmed escapees and wild conspecifics represents one of the major environmental challenges faced by the Atlantic salmon aquaculture industry. In order to mitigate genetic interactions, triploid (sterile) farmed fish can be produced. However, triploids may still develop se...
