Ocean Acidification Threaten Fish Population

"In our study, we found that while larvae of barramundi are attracted to the sounds of tropical estuaries, larvae raised under future ocean conditions with elevated CO2 were deterred by these natural sounds," says Professor Nagelkerken. "Moreover, under elevated CO2, larval barramundi were attracted to the wrong sounds." The other sounds were noises found on cold water reefs (which are not the correct habitat for barramundi) and artificial sounds or 'white noise.'

Professor Sean Connell, from the University's Southern Seas Ecology Laboratories, says that if ocean acidification causes larvae to be deterred to the sounds of their habitats, and attracts them to irrelevant sounds, they could end up in the wrong habitat or in places where they cannot survive.
