Salmon feed ingridients

Economic Returns of Ingredient Substitution in Salmon Feed, 1996–2024.<br>This study quantifies the economic impact of the salmon aquaculture industry's transition from marine-based to plant-based feed ingredients over nearly three decades. We construct a Feed Cost Index for Norwegian salmon aquaculture that explicitly accounts for time-varying feed composition, using monthly commodity price data and documented formulation changes.Key findings:<br>- Maintaining the traditional 1990 formulation (89% marine ingredients) would have increased feed costs by 59% on average during 2015–2023- The transition generated industry savings exceeding 850 million USD annually at current Norwegian production levels<br>- Plant-based formulations reduced feed cost volatility by 28%, improving cost predictability for producers.The dataset contains annual ingredient prices (fish meal, fish oil, soybean meal, rapeseed oil), feed composition shares, and calculated feed costs under actual and counterfactual formulation scenarios. Data sources include World Bank Commodity Markets, Statistics Norway, and published feed composition studies.This research demonstrates that economic incentives have strongly reinforced sustainability-driven changes in salmon feed formulation, with implications for evaluating novel ingredients as they enter commercial production.

《1996—2024年三文鱼饲料原料替代的经济收益》
本研究量化了近三十年来三文鱼水产养殖业（salmon aquaculture）从海洋基饲料原料（marine-based feed ingredients）向植物基饲料原料（plant-based feed ingredients）转型所带来的经济影响。研究团队基于月度大宗商品价格数据与已公开的饲料配方变更记录，构建了适配挪威三文鱼养殖业的饲料成本指数（Feed Cost Index），该指数可明确体现随时间动态变化的饲料组成情况。

核心研究发现：
- 若维持1990年代的传统配方（海洋原料占比89%），2015至2023年间饲料成本平均将上涨59%
- 以当前挪威三文鱼的生产水平计算，此次转型每年可为行业节省超8.5亿美元的成本
- 植物基饲料配方可将饲料成本波动率降低28%，提升了养殖厂商的成本可预测性

本数据集涵盖年度原料价格数据（包括鱼粉、鱼油、豆粕、菜籽油）、饲料组成占比，以及实际生产与反事实（counterfactual）配方场景下测算得到的饲料成本。数据来源包括世界银行大宗商品市场数据库、挪威统计局及已发表的饲料配方相关研究成果。

本研究证实，经济激励因素极大推动了三文鱼饲料配方向可持续方向的变革，该结论可为评估即将商业化量产的新型饲料原料提供重要参考依据。
