Rising ocean temperatures, pollution have oysters in hot water


Dated: 31 January 2007

Oyster stocks may be in shorter supply in the near future.

Oysters exposed to high water temperatures and a common heavy metal are unable to obtain sufficient oxygen and convert it to cellular energy, according to a new study presented at The American Physiological Society conference, Comparative Physiology 2006.


The study showed how cadmium, a heavy metal, reduces the oyster's tolerance of warmer water temperatures and makes it more vulnerable during the summer when water temperatures rise.
