Disse endringene gjør skreien mer sårbar for ytterligere påvirkning og kan trolig knyttes til endringer i vandringsmønsteret til torsken i senere tid. Mao ja, vi påvirker våre fiskebestander kanskje mer enn vi aner …

Verdens største torskebestand er påvirket av mennesker. Endringen er synlig i genene. - Titan.uio.no Skreien er annerledes i dag enn for 100 år siden. Torsken er ikke genmanipulert. Endringene er menneskeskapte, ifølge ny forskning.

I flere tiår har det vært debattert om vi mennesker påvirker genene til bestandene vi høster. I ett nytt studie - hvor vi har fått tilgang på over hundre år gamle prøver av skrei samlet inn i Lofoten - avdekker nettopp dette!! For mere info se:

A century of anthropogenic perturbations impact genomic signatures of the iconic migratory Atlantic cod Retrospective assessment of the iconic migratory Atlantic cod uncovers human-induced genome-wide changes during the last century.

Finally is this story out public!! With an amazing historical dataset from IMR (@havforskningsinstituttet) we demonstrate how human perturbations impact the genomic signal in one of the largest cod stocks in the world: the northeast arctic cod | Science Advances www.science.org/doi/10.1126/...
