【 摘 要 】

ABSTRACT: Farmed fish sometimes escape and enter natural environments, where they mix with wild fish populations and can have negative effects. Marking farmed fish is a prerequisite for the identification of the origin of escapees and for guiding technical investigations to determine the cause of an escape event and improve farming practices. We tested transgenerational marking with enriched stable isotopes to assess its effectiveness as an accurate, feasible and cost-effective marking method for Atlantic salmon
