日本語
海面養殖のLCA研究83件を体系的にレビューしたナラティブ統合。給餌型魚類・エビは飼料供給網と農場エネルギー、二枚貝・海藻は孵化場や収穫後処理、炭素・栄養会計が主要因となる。機能単位やシステム境界、配分規則の不統一が比較を妨げており、透明性・地域化・将来志向の評価への移行を提言する。
English
A narrative synthesis of 83 mariculture LCA studies. Fed finfish and shrimp are driven by feed supply chains, farm energy, and nutrient emissions; bivalves and seaweed by hatcheries, infrastructure, and carbon/nutrient accounting. Inconsistent functional units, boundaries, and allocation rules limit cross-study comparison, calling for transparent, regionalized, prospective assessments.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は海面養殖（ブリ、マガキ、ホタテ、海藻）の主要国であり、Scope 3や一次産業の環境フットプリント開示が進む中、本レビューは水産物の炭素・栄養会計の方法論的基盤を提供する。SSBJや統合報告での生物由来排出の扱いを検討する際の参照点となる。
In the global GX context
As blue food enters climate disclosure (Scope 3, CSRD, ISSB), this review exposes the methodological fragmentation in mariculture LCA that undermines comparability of seafood footprints. It offers a roadmap for transparent, regionalized accounting that global disclosure frameworks will need to absorb for aquaculture supply chains.

📄 Abstract（原文）
Mariculture is expected to support sustainable food systems and coastal economies, yet its environmental performance varies markedly among production systems. Life-cycle assessment (LCA) links farm operations with upstream and downstream processes, but inconsistent functional units, system boundaries, allocation rules, impact categories, and ecological-process accounting limit cross-study comparison. This study presents a narrative synthesis of 83 studies identified through a systematic search of the Web of Science Core Collection and retained after structured relevance screening and full-text verification. The main findings are as follows: Fed finfish and shrimp systems were primarily influenced by feed supply chains, farm energy use, survival, and nutrient emissions. Bivalve and seaweed systems shifted attention toward hatcheries, infrastructure, vessels, yield, post-harvest handling, and carbon or nutrient accounting. Integrated systems and emerging technologies showed mitigation potential, but their benefits depended on uptake efficiency, electricity mixes, infrastructure lifetimes, and allocation choices. Overall, the evidence supports a transition from isolated product footprints toward transparent, regionalized, and prospective assessments. Future research should prioritize inventory transparency, regionalized impact assessment, nutrition-sensitive functional units, separate reporting of ecosystem services and conventional environmental burdens, and explicit boundaries for environmental claims.
