【摘要】 海洋硬骨鱼类在全球碳循环中扮演着重要角色，其生理活动对海洋碳汇具有显著影响。研究回顾并总结了海洋硬骨鱼类对海洋碳汇影响的研究进展，分析了鱼类通过主动和被动运输机制对海洋碳循环的贡献，并整理了关于碳酸盐排泄的现有模型。研究认为，海洋硬骨鱼类通过呼吸作用、垂直洄游和死亡沉降等过程，对海洋深层的碳储存具有重要作用。这些过程不仅与鱼类的代谢活动紧密相关，而且还受到水温、盐度、pH值等环境因素的影响。然而，当前对海洋硬骨鱼碳汇的定量估算有限，且缺乏系统性研究。研究强调了未来深入研究的必要性，包括全球范围内的鱼类固碳潜力评估、环境因素对鱼类固碳效率的影响、以及鱼类死亡沉降作为碳汇过程的评估。研究建议建立全球鱼类固碳数据库等基础平台，以促进国际合作并提高对鱼类在海洋碳循环中作用的科学认识。更多还原

【Abstract】 Marine osteichthyes play an important role in the global carbon cycle, and their physiological activities have a significant impact on the oceanic carbon sink. This paper reviewed and summarized the progress of research on the impact of marine osteichthyes on the oceanic carbon sink, then analyzed the contribution of fishes to the oceanic carbon cycle through active and passive transport mechanisms, finally collated existing models on carbonate excretion. The research suggested that marine osteichthyes play an important role in the carbon storage of the deep ocean through processes such as respiration, vertical migration, and the sinking of dead organisms. These processes are not only closely related to the metabolic activities of the fishes but are also influenced by environmental factors such as water temperature, salinity, and pH levels. However, current quantitative estimates of the carbon sequestration by marine osteichthyes are limited, and there is a dearth of comprehensive research in this field. This paper emphasized the necessity for further in-depth research in the future, including the assessment of the global carbon fixation potential of fishes, the impact of environmental factors on the efficiency of fish carbon fixation, and the evaluation of the process of dead fish as a carbon sink. Additionally, the paper suggested the establishment of a global database for fish carbon fixation to facilitate international cooperation and enhance the scientific understanding of the role of fishes in the marine carbon cycle.更多还原
