Ocean acidification has become serious, and seawater hypoxia has become evident in acidified waters. The combination of such stressors may have interactive effects on the fitness of marine organisms. In order to investigate the interactive effects of seawater acidification and hypoxia on the early development of marine bivalves, the eggs and sperm of the thick shell mussel Mytilus coruscus were exposed to combined treatments of pH (8.1, 7.7, 7.3) and dissolved oxygen (2, 6 mg/L) for 96 h culture observation to investigate the interactive effects of seawater acidification and hypoxia on the early development of marine bivalves. Results showed that acidification and hypoxia had significant negative effects on various parameters of the early development of the thick shell mussel. However, hypoxia had no effect on fertilization rate. Significant interactions between acidification and hypoxia were observed during the experiment. Short-term exposure negatively influenced the early development of the thick shell mussel but did not affect its survival. The effects of long-term exposure to these two environmental stresses need further study.

海洋酸化和缺氧联合作用对厚壳贻贝Mytilus coruscus早期发育的影响

海洋酸化已变得严重，并且在酸化水域中海水缺氧已变得明显。此类压力源的组合可能会对海洋生物的适应性产生交互作用。为了研究海水酸化和缺氧对海洋双壳类动物早期发育的相互作用，将厚壳贻贝Mytilus coruscus的卵和精子暴露于pH（8.1、7.7、7.3）和溶解氧（2 （6 mg / L）进行96 h培养观察，以研究海水酸化和缺氧对海洋双壳类动物早期发育的相互作用。结果表明，酸化和缺氧对厚壳贻贝早期发育的各个参数具有明显的负面影响。但是，低氧对受精率没有影响。在实验过程中观察到酸化和缺氧之间的显着相互作用。短期接触会对厚壳贻贝的早期发育产生负面影响，但不影响其生存。长期暴露于这两种环境压力的影响有待进一步研究。
