大规模贝类养殖对近海的碳循环过程产生了重要影响，形成了一个“可移出的碳汇”。根据2013年4月-2014年2月对东极海洋牧场厚壳贻贝筏式养殖区Ⅰ龄个体跟踪调查数据，评估了厚壳贻贝和附着生物的固碳量，并进行了固碳速率的标准化处理。研究显示，一个养殖周期内筏式养殖区厚壳贻贝和附着生物固碳量分别为102.24 t和4.88 t，其固碳速率分别为5.43 tC/(hm2·a)和0.26 tC/(hm2·a)；筏式养殖区减排CO2的生态服务价值量为37.17万元；贝壳和软组织的湿重比、含水率和碳含量差异均不显著（P>0.05），能使核算养殖贝类碳汇能力的程序简单化，本研究的方法和结论可用于评估其他海域养殖厚壳贻贝的固碳量；东极海洋牧场附着生物移出碳量为厚壳贻贝的4.77%，在筏式养殖区生态系统碳循环中的作用亦不可忽视。
大規模貝類養殖對近海的碳循環過程產生瞭重要影響，形成瞭一箇“可移齣的碳彙”。根據2013年4月-2014年2月對東極海洋牧場厚殼貽貝筏式養殖區Ⅰ齡箇體跟蹤調查數據，評估瞭厚殼貽貝和附著生物的固碳量，併進行瞭固碳速率的標準化處理。研究顯示，一箇養殖週期內筏式養殖區厚殼貽貝和附著生物固碳量分彆為102.24 t和4.88 t，其固碳速率分彆為5.43 tC/(hm2·a)和0.26 tC/(hm2·a)；筏式養殖區減排CO2的生態服務價值量為37.17萬元；貝殼和軟組織的濕重比、含水率和碳含量差異均不顯著（P>0.05），能使覈算養殖貝類碳彙能力的程序簡單化，本研究的方法和結論可用于評估其他海域養殖厚殼貽貝的固碳量；東極海洋牧場附著生物移齣碳量為厚殼貽貝的4.77%，在筏式養殖區生態繫統碳循環中的作用亦不可忽視。

Large-scale shellfish aquaculture had a significant influence on the carbon cycle process of coastal waters, and formed a"removable carbon sink". Based on the data of tracking survery of one-year-old Mytilus cor-uscus from April 2013 to February 2014 in the raft culture zones of Dongji marine ranching, the carbon sequestra-tion of M. coruscus and fouling organisms were estimated, and the carbon sequestration rates were standardized. The result showed that the carbon sequestration of M. coruscus and fouling organisms in one year culture cycle were 102.24 t and 4.88 t, respectively, and carbon sequestration rates were 5.43 tC/ (hm 2·a) and 0.26 tC/ (hm2·a), respectively. The ecological service value of CO2 emission reduction in the raft culture zones was estimated to be 371 700 RMB. There were no significant difference on wet weight ratios, water content and carbon content of shells and soft tissue, which could simplify the procedure of accounting the carbon sink capacity of cultured shellfish. In addition, the methods and conclusions of this study could be used to evaluate carbon sequestration of cultured M. coruscus in other waters. The carbon content removed by fouling organisms was estimated to be 4.77 percent of M. coruscus, and the role of fouling organisms in ecosystem carbon cycle of the raft culture zones couldn ’t be ignored.
