In 2013 Oona M. Lönnstedt and colleagues published a study concluding that ocean acidification has a strong effect on the behavior of Pomacentrus amboinensis, a species of fish. However, Lönnstedt and colleagues’ study relied on a mean sample size of only about 28 fish. In a 2022 review of various scientists’ conclusions about the impacts of ocean acidification on fish behavior, Jeff C. Clements and colleagues caution that relying on such a relatively small sample size can increase the potential for biased analysis. Such analysis, in turn, can contribute to reports of exaggerated effects.
