Rising carbon dioxide may rob fish larvae of their ability to sense predators and survive

Baby fish become confused and reckless in water with high levels of dissolved carbon dioxide, a new study shows. This leads to higher death rates and may mean that rising atmospheric carbon dioxide, which causes ocean acidification, will reduce the number of fish in the ocean.

“It shows we should be concerned with even minor changes in aquatic ecology, because it’s going to have dramatic effects on the survival of fish,” says Grant Brown, a freshwater behavioral ecologist at Concordia Univers...
