Farmed Oysters Able To Protect Themselves From Acidification

Oysters bred for fast growth and disease resistance are able to adapt their shell growth to protect themselves from environmental acidification, according to new research.

Ocean and coastal acidification — the ongoing increase in the acidity of the world’s oceans — hampers some organisms, such as oysters, from producing and maintaining their shells. However, experts now believe that for oysters there is a potential solution to the problem.

A team led by Dr Susan Fitzer, a Research Fellow at the University of Stirling’s Institute of Aquaculture (IoA), studied Sydney Rock Oysters in New South Wales, Australia, and found that resilient strains of this oyster — generated through targeted breeding — can cope better with more acidic seawater conditions.
