Ocean acidification impairs olfactory discrimination and homing ability of a marine fish

This article investigates the effects of human acidification of due to elevated CO2 levels. One of the main effects of human acidification is the change in olfactory-based cues of the larvae of coastal marine species. Most commonly these species use these olfactory cues to detect adult habitats. A study was performed on larval clownfish in which it was found that the clownfish had difficulty distinguishing between suitable habitats as ocean acidification levels increased. This could result in issues of the sustainability of marine population sustainability.
