二枚貝養殖が微生物炭素ポンプ（MCP）を通じて炭素隔離を促進する可能性を批判的に検討したレビュー。貝の排泄や一次生産増加によるDOC増加、植物プランクトン群集の小型化が難分解性DOC（RDOC）生成を促す可能性を示す一方、直接証拠の不足を指摘する。持続可能な養殖管理と気候緩和・食料安全保障の両立に示唆を与える。
English
This review critically assesses how commercial bivalve aquaculture may enhance the microbial carbon pump (MCP) and long-term carbon sequestration. It argues that bivalve excretion and elevated primary productivity raise dissolved organic carbon and may favor recalcitrant DOC production, while shifts toward cyanobacteria and picophytoplankton could further boost sequestration. It cautions that direct evidence for RDOC production remains lacking, and offers implications for sustainable aquaculture management, climate mitigation, and food security.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
ブルーカーボンは日本のGX・気候変動適応策で関心が高まる領域だが、本稿は自然科学レビューでありSSBJ開示や投資家対応への直接的示唆は限定的。水産養殖の炭素クレジット化を検討する際の科学的基礎として参照価値がある。
In the global GX context
Blue carbon and aquaculture-based sequestration are increasingly discussed in voluntary carbon markets and nature-related disclosure (TNFD), though this paper is a scientific review rather than a disclosure framework. It adds a cautionary scientific baseline for anyone claiming sequestration credits from bivalve aquaculture.

📄 Abstract（原文）
The ocean, the world's largest carbon pool, plays a critical role in regulating the global climate. Within this system, the microbial carbon pump (MCP) is a key mechanism for long-term carbon sequestration, converting organic carbon into diverse and structurally complex dissolved molecules that persist in the environment. Despite the dramatic expansion of bivalve aquaculture in recent decades, its contribution to carbon sequestration through the MCP remains poorly understood and understudied. This article critically assesses the impact of bivalve aquaculture on the carbon cycle, particularly its role in enhancing the MCP. Bivalve aquaculture influences the carbon cycle in several ways. First, it increases dissolved organic carbon (DOC) in surrounding waters through direct excretion by bivalves and enhances primary productivity, particularly in oligotrophic waters. These changes boost microbial biomass and may potentially accelerate the production of recalcitrant dissolved organic carbon (RDOC), a key component of long-term carbon storage; however, increased DOC release and microbial activity do not by themselves demonstrate RDOC production, and direct evidence from bivalve aquaculture is currently lacking. Second, intensive bivalve aquaculture alters phytoplankton community structure, shifting dominance from diatoms to cyanobacteria and picophytoplankton. These smaller phytoplankton groups tend to release more RDOC into the environment compared to diatoms and microphytoplankton, further contributing to carbon sequestration. By elucidating the mechanisms through which bivalve aquaculture enhances carbon sequestration via the MCP, this article provides valuable insights for developing sustainable bivalve fisheries and aquaculture management strategies. Such strategies can harness the potential of bivalve aquaculture to mitigate climate change impacts while supporting global food security.
