The replacement of fish oil with plant oils is a common practice in aquaculture to compensate for the shortage of fish oil supply and has been thoroughly studied. However, because the experimental conditions vary in many aspects, the results are usually inconsistent quantitatively. Therefore, a meta-analysis was conducted based on a dataset containing 328 articles to systematically model the influence of plant oils on the main aquaculture fish. In addition to demonstrating the species-specific dose-dependent impact of plant oils on fish growth, feed utilization efficiency, lipid deposition and health parameters, we have also investigated the role of other factors in this process. We found that the adverse effects caused by plant oils worsen as the experimental duration extends for Atlantic salmon, while Gilthead seabream and European seabass gradually adapt to the change. Further, water temperature could be a decisive factor for Rainbow trout, and early adaptation to plant oils would be helpful for Gilthead seabream. Moreover, sufficient fishmeal supply could alleviate the adverse effects caused by plant oils for most species, but for Gilthead seabream and European seabass, the growth suppression effect of plant oil was larger when fed high-fishmeal diets. Besides, by comprehensively considering the effects of plant oils, we matched the potential optimal plant oil for each fish species. Our article quantitatively modelled the adverse effects of replacing fish oil with plant oils, investigated the influences of assistant factors and offered a panorama of the research status with emphasis on potential breakthrough orientations.

模拟用植物油替代鱼油的影响：为主要养殖鱼类匹配最佳植物油的荟萃分析


用植物油替代鱼油是水产养殖中为弥补鱼油供应短缺的常见做法，并已得到深入研究。然而，由于实验条件各方面存在差异，定量结果通常不一致。因此，基于包含328篇文章的数据集进行荟萃分析，系统地模拟植物油对主要水产养殖鱼类的影响。除了证明植物油对鱼类生长、饲料利用效率、脂质沉积和健康参数的物种特异性剂量依赖性影响外，我们还研究了其他因素在此过程中的作用。我们发现，随着实验时间的延长，大西洋鲑鱼植物油造成的不利影响会加剧，而金头鲷和欧洲鲈鱼则逐渐适应这种变化。此外，水温可能是虹鳟鱼的决定性因素，而早期适应植物油将有助于金头鲷。此外，充足的鱼粉供应可以减轻植物油对大多数物种造成的不利影响，但对于金头鲷和欧洲鲈鱼来说，饲喂高鱼粉饲料时植物油的生长抑制作用更大。此外，通过综合考虑植物油的作用，我们为每种鱼类匹配了潜在的最佳植物油。我们的文章定量模拟了用植物油替代鱼油的不利影响，调查了辅助因素的影响，并提供了研究现状的全景，重点是潜在的突破方向。
