If acidification continues unabated, the impairment of sensory ability will reduce population sustainability of many marine species, with potentially profound consequences for marine diversity.

It is shown that abnormal olfactory preferences and loss of behavioural lateralization exhibited by two species of larval coral reef fish exposed to high CO2 can be rapidly and effectively reversed by treatment with an antagonist of the GABA-A receptor, a major neurotransmitter receptor in the vertebrate brain.
Ocean acidification disrupts the innate ability of fish to detect predator olfactory cues.
It is shown that newly hatched larvae of the marine fish Amphiprion percula innately detect predators using olfactory cues and this ability is retained through to settlement and translates to higher mortality as a result of increased predation risk.
Replenishment of fish populations is threatened by ocean acidification

Levels of dissolved CO2 predicted to occur in the ocean this century alter the behavior of larval fish and dramatically decrease their survival during recruitment to adult populations and have far-reaching consequences for the sustainability of fish populations.

Results suggest that levels of ocean acidification likely to be experienced in the near future might not, in isolation, significantly disadvantage the growth and performance of larvae from benthic-spawning marine fishes.
Effect of ocean acidification on otolith development in larvae of a tropical marine fish

The hypothesis that pH regulation in the otolith endolymph can lead to increased precipitation of CaCO 3 in otoliths of larval fish exposed to elevated CO 2 is supported, however, the results also show that sensitivity varies considerably among species.
Behavioural impairment in reef fishes caused by ocean acidification at CO2 seeps

- 1 June 2014
Research shows that reef fishes at natural volcanic CO2 seeps also exhibit behavioural abnormalities, and that behaviour does not acclimate with extended exposure to high CO2, suggesting fish communities are likely to face a serious threat from CO2-induced behavioural abnormalities in the future as ocean acidification becomes widespread.
How Nemo finds home: the neuroecology of dispersal and of population connectivity in larvae of marine fishes.

Current understanding of sensory cues marine fish larvae use for orientation in the pelagic environment are reviewed and how sensory abilities of larvae develop and are used to achieve orientation are reviewed with particular emphasis on coral-reef fishes.
Ocean acidification erodes crucial auditory behaviour in a marine fish

This study provides, to the authors' knowledge, the first evidence that ocean acidification affects the auditory response of fishes, with potentially detrimental impacts on early survival.
Intrageneric variation in antipredator responses of coral reef fishes affected by ocean acidification: implications for climate change projections on marine communities

Our planet is experiencing an increase in the concentration of atmospheric carbon dioxide (CO2) unprecedented in the past 800 000 years. About 30% of excess atmospheric CO2 is absorbed by the oceans,…
