Oppdrettstorsken trenger ikke rømme for å spre sine gener : Farmed cod do not need to escape to spread their genes

Abstract

Escaped farmed salmon that mix with wild fish have recently received a good deal of attention. But cod, our next important farmed species, can spread its genetic material without even escaping, since they spawn inside their sea-cages. The Institute of Marine Research is studying the consequences of this situation for wild cod.
