Carbon dioxide affecting fish brains
Date: 17.1.2012
Rising human carbon dioxide emissions may be affecting the brains and central nervous systems of sea fish, with serious consequences for their survival, according to new research.
Carbon dioxide concentrations predicted to occur in the ocean by the end of this century will interfere with fishes' ability to hear, smell, turn and evade predators, the research found.
In a paper published in the journal Nature Climate Change, Munday and his colleagues also detail what they say is world-first evidence that high CO2 levels in sea water disrupts a key brain receptor in fish.
