Genetiske påvirkninger fra oppdrett av kveite

Så vidt vi er kjent med gyter ikke kveite frivillig i merder. I landbasert oppdrett er det observert naturlig gyting i store kar, men dette er svært vanskelig å få til. I oppdrett kjønnsmodner i tillegg hunnene så sent at de slaktes før de når pubertet. Sidene hannene kjønnsmodner før de når slaktbar størrelse, brukes det ofte kontinuerlig tilleggsbelysning i merdene som vil utsette modningen. Foreløpig må vi derfor anta at det ikke slippes

befruktede egg ut fra kveiteoppdrett. Siden kveite oppdrettes i merd, kan vi forvente rømming. Noe rømt fisk vil overleve, andel ikke kjent, og vi vet heller ikke om oppdrettet rømt kveite vil gyte i naturen.
