Seawater carbonate chemistry and oyster physiological performance

This study investigated the physiological responses of juvenile Pacific oyster Crassostrea gigas exposed for 81 days to current and ocean acidification and warming conditions (+3 ◦C, − 0.3 pH units) under two tidal treatments (0 vs. 30 % emersion) and two food levels (ad libitum vs. limited). We measured growth, reproduction, food ingestion, respiration, and biochemical traits like energy reserves and membrane fatty acids. At the experiment's end, oysters were challenged with a viral disease to assess the physiological cost of acclimation and potential trade-offs.
