A literature review revealed a wide variety of ocean acidification (OA) effects on fish. Tank experiments revealed both positive (growth and survival) and negative effects (metabolic performance and hearing) of OA and elevated temperature on snapper. A snapper population model that adjusted parameters to account for OA and elevated temperature suggested positive and negative outcomes were possible. Given this, further data collection and frequent monitoring to inform management would be prudent.
