sustainable and responsible production in aquaculture calls for innovative implementation of recirculating aquaculture systems (RAS), which are extraordinarily complex, requiring the integration of various fields of science and technology to reach the desired productivity. In this case study, we report a four-month observation using a large language model (LLM) that – collaboratively with human expertise – analyzed and resolved complex challenges in a Macrobrachium rosenbergii RAS hatchery. Unacceptable larval and post-larval mortality prompted the integration into hatchery management of an AI decision-support system as a strategic management partner, enabling exploration across chemical, biological, physical, engineering, and behavioral domains. Key interventions suggested by the AI agent included mineral balance recalibration, microbial load diagnostics, behavioral pattern decoding, and lighting and flow engineering. Outcomes were evaluated in terms of a reduction in larval mortality and improved rates of larval metamorphosis to post larvae. Central to the process was the presence of a guiding human entity, steering AI's analytical power through deliberate questioning and contextual framing. This case study suggests that AI has the potential to improve intensive aquaculture systems. However, the tendency of AI agents to oversimplify complex systems requires the direction and guidance of a human expert to lead AI-human conversations. The adoption of LLMs in RAS-based aquaculture, bridging the gaps between raw data and actionable insights, has the potential to drive both the efficiency and the long-term sustainability of the

rosenbergii）RAS孵化场中的复杂挑战。不可接受的幼体和后期幼体死亡率促使将AI决策支持系统作为战略管理伙伴纳入孵化场管理，从而能够在化学、生物、物理、工程和行为领域进行探索。AI代理建议的关键干预措施包括矿物质平衡重新校准、微生物负荷诊断、行为模式解码以及光照和水流工程。结果通过幼体死亡率的降低和幼体变态为后期幼体的比率提高来评估。该过程的核心是有一个指导性的人类实体，通过有意的提问和情境构建来引导AI的分析能力。本案例研究表明，AI有潜力改善集约化水产养殖系统。然而，AI代理倾向于过度简化复杂系统，需要人类专家的指导和引导来主导AI与人类的对话。在基于RAS的水产养殖中采用LLM，弥合原始数据与可操作见解之间的差距，有潜力推动水产养殖行业的效率和长期可持续性。","Smart

operating within planetary boundaries requires nutrient management strategies that reduce import dependency without shifting environmental burdens. This study develops and evaluates four contrasting normative scenarios for nutrient management in Sweden in 2045: industrial-scale domestic fertilizer production, industrial-scale nutrient recovery, decentralized “fork-to-backyard” nutrient cycling, and response diversity. Methods The scenarios were assessed using the Sustainability Assessment Framework for Scenarios (SAFS). The framework defines relevant contextual factors and applies a structured qualitative assessment across technological, environmental, and social\u002Fgovernance dimensions. Resource use and circularity were assessed within the environmental dimension, while self-sufficiency was treated as a shared scenario objective. An interrelation analysis and an ordinal scoring scale were used to identify and compare risks, opportunities, trade-offs, and uncertainties without ranking the scenarios. Results The assessment revealed persistent trade-offs that are relevant not only to Sweden but also to other high-input, import-dependent agri-food systems seeking greater nutrient self-sufficiency. Decentralized recycling showed the greatest potential to improve climate and eutrophication outcomes and strengthen democratic participation but involved high implementation and operational complexity, as well as demanding quality assurance requirements. Industrial recovery improved eutrophication performance and circularity while maintaining standardized fertilizer products, but depended on energy and process trade-offs and required substantial investments. Industrial production provided predictable products and perceived safety benefits but risked higher resource intensity and did not inherently reduce pressure on biogeochemical planetary boundaries. Response diversity increased resilience and reduced dependence on single supply pathways but could require greater resource use and coordination. Discussion The combined scenario and SAFS approach clarified key risks, opportunities, and uncertainties, including the influence of electricity mix, achievable nutrient-loss reductions, and contaminant control. The results demonstrate that no single pathway resolves all sustainability challenges and highlight the importance of considering technological, environmental, and governance dimensions simultaneously when designing nutrient self-sufficiency strategies. The approach can support decision-making in Sweden and other regions facing similar sustainability, governance, and supply-security challenges.","引言 在地球边界内确保长期粮食安全，需要既能减少进口依赖又不转移环境负担的养分管理策略。本研究针对瑞典2045年的养分管理，开发并评估了四种相互对照的规范性情景：工业化国内肥料生产、工业化养分回收、去中心化“从餐桌到后院”的养分循环，以及响应多样性。方法 采用情景可持续性评估框架（Sustainability Assessment Framework for Scenarios, SAFS）对这些情景进行评估。该框架界定了相关情境因素，并在技术、环境和社会\u002F治理维度上应用结构化的定性评估。资源利用和循环性在环境维度内评估，而自给自足则被视为各情景的共同目标。采用相互关系分析和序数评分量表来识别和比较风险、机遇、权衡与不确定性，而不对情景进行排序。结果 评估揭示了持续存在的权衡，这些权衡不仅与瑞典相关，也与其他寻求更高养分自给率的高投入、依赖进口的农食系统相关。去中心化回收在改善气候和富营养化结果以及加强民主参与方面显示出最大潜力，但实施和运营复杂性高，且质量保证要求苛刻。工业化回收改善了富营养化表现和循环性，同时维持了标准化肥料产品，但依赖能源和工艺权衡，并需要大量投资。工业化生产提供了可预测的产品和感知到的安全效益，但存在资源强度较高的风险，且并未从根本上减轻对生物地球化学地球边界的压力。响应多样性增强了韧性并减少了对单一供应路径的依赖，但可能需要更多的资源利用和协调。讨论 情景与SAFS相结合的方法阐明了关键风险、机遇和不确定性，包括电力结构的影响、可实现的养分损失削减以及污染物控制。结果表明，没有任何单一途径能够解决所有可持续性挑战，并凸显了在设计养分管理策略时同时考虑技术、环境和治理维度的重要性。","Frontiers in Sustainable Food Systems",79,{"impact":17,"substance":18,"depth":17,"authority":147,"freshness":148,"relevant":22,"comment":337},"该研究以瑞典为对象，系统比较四种养分自给路径的权衡，方法规范、结论对高投入进口依赖型农业体系有借鉴价值，但属境外情景研究，国内落地影响有限。",[339],{"name":334,"url":331},[341,342,31,343,344],"粮食安全","可持续农业","养分管理","瑞典",{"code":346,"slug":347,"name":348,"path":349,"parent_code":350},"F3","fertilizers","肥料与水肥一体化","\u002Ftopic\u002Finputs-equipment\u002Ffertilizers","F",[],{"status":43,"locked":14,"version":44,"method":45,"evidence":353},{"candidates":354,"agricultural_evidence":50},[355,361,367],{"code":346,"score":20,"supported":50,"title":356,"abstract":357,"tags":360},[],[358,343,359],"肥料","fertilizer",[343],{"code":362,"score":57,"supported":50,"title":363,"abstract":364,"tags":366},"A8",[],[341,365],"food security",[341],{"code":83,"score":126,"supported":14,"title":368,"abstract":369,"tags":370},[],[],[342,31],[372,373],"瑞典 养分自给 情景评估","Frontiers 可持续食物系统 养分循环","瑞典养分自给情景评估-5371","10.3389\u002Ffsufs.2026.1952306",{"doi":375,"openalex_id":377,"authors":378,"venue":334,"cited_by_count":207,"oa_url":387,"card":388,"direction":392,"ingested_from":216},"W7222945601",[379,381,384],{"name":380,"orcid":8},"Priscila de Morais Lima",{"name":382,"orcid":383},"Verena Germann","https:\u002F\u002Forcid.org\u002F0000-0002-3867-0953",{"name":385,"orcid":386},"Jennifer Rae McConville","https:\u002F\u002Forcid.org\u002F0000-0003-0373-685X","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1952306\u002Fpdf",{"tldr":389,"method":390,"finding":391,"direction":392,"opportunity":393},"评估瑞典2045年四种养分管理情景，比较其可持续性与自给自足潜力。","用SAFS框架对四种规范情景做技术、环境、社会维度的定性评估与互关系分析。","无单一方案能解决所有挑战，分散循环在气候与富营养化上最优但实施复杂。","农业绿色发展与碳","可将情景评估框架与养分循环模型耦合，量化电力结构、损失削减与污染物控制的不确定性。","2026-10-20T23:30:06.714933Z",{"id":396,"title":397,"url":398,"summary":399,"summary_zh":8,"content":8,"source_name":400,"source_url":8,"published_at":8,"category":143,"cover_url":8,"hotness":20,"is_selected":14,"score":401,"score_detail":402,"sources":404,"tags":406,"primary_topic":410,"secondary_topics":414,"classification":415,"search_phrases":427,"slug":430,"view_count":126,"doi":8,"paper":431,"created_at":440},5225,"数字基础设施能否提高农业全要素生产率?——基于浙江智慧农业云平台建设的经验证据","http:\u002F\u002Fwww.qikanvip.com\u002Fqkml\u002F174580.html","《河南师范大学学报(哲学社会科学版)》2026年第3期,李荣华、张怡君以浙江智慧农业云平台设立为准自然实验,采用合成控制法系统评估智慧农业云平台对农业全要素生产率的影响,发现平台设立对TFP提升具有稳健且显著的政策效应,同时驱动技术进步与技术效率两个维度的突破。","河南师范大学学报(2026)",74,{"impact":17,"substance":18,"depth":17,"authority":174,"freshness":126,"relevant":22,"comment":403},"核心期刊论文，以浙江智慧农业云平台为准自然实验，用合成控制法验证数字基础设施对农业TFP的稳健提升效应，方法规范、结论有政策参考价值，但时效性偏弱。",[405],{"name":400,"url":398},[407,153,30,408,409],"数字乡村","农业全要素生产率","合成控制法",{"code":186,"slug":411,"name":412,"path":413,"parent_code":164},"smart-agriculture","智慧农业总论","\u002Ftopic\u002Fdigital-agriculture\u002Fsmart-agriculture",[],{"status":43,"locked":14,"version":44,"method":45,"evidence":416},{"candidates":417,"agricultural_evidence":50},[418,422],{"code":186,"score":228,"supported":50,"title":419,"abstract":420,"tags":421},[153],[153],[153],{"code":423,"score":22,"supported":14,"title":424,"abstract":425,"tags":426},"I6",[],[],[407],[428,429],"浙江 智慧农业云平台","农业全要素生产率 数字基础设施","浙江智慧农业云平台-5225",{"doi":8,"openalex_id":8,"authors":432,"venue":8,"cited_by_count":207,"oa_url":8,"card":433,"direction":437,"ingested_from":439},[],{"tldr":434,"method":435,"finding":436,"direction":437,"opportunity":438},"以浙江智慧农业云平台为准自然实验，评估数字基础设施对农业全要素生产率的影响。","合成控制法，基于浙江智慧农业云平台建设的准自然实验数据。","平台设立对农业TFP提升有稳健显著的政策效应，并驱动技术进步与技术效率双突破。","数字乡村与农业信息化","可延伸研究不同区域数字基础设施对TFP的异质性效应及技术效率提升的微观机制。","agent","2026-10-18T00:05:30.510965Z"]
