Turun yliopistossa tehty – Kalastus muuttaa geenien ilmentymistä kaloissa

Kalastus on usein valikoivaa ja poistaa kookkaat yksilöt kalakannasta. Suurikokoisiin kaloihin kohdistuva kalastus saattaa ajan myötä aiheuttaa hyvin hitaasti palautuvia perinnöllisiä muutoksia kalakannoissa. Turun yliopistossa tehty tutkimus osoittaa, että kookkaiden yksilöiden poistaminen muuttaa geenien ilmentymistä kaloissa. Nämä muutokset palautuvat hitaasti. … Lue loppuun
