EU aquaculture produces only a small fraction of the internal demand of aquatic foods, but boosting this activity must be done in compliance with high standards of environmental protection and social benefits, as fostered by the policies on circular economy recently launched by the EU. Nevertheless, the assessment of the environmental sustainability of aquaculture and other food production systems is complex, due to the different tools and approaches available. Moreover, the current EU regulatory framework may be restricting the options to implement some circular solutions. This paper examines the controversies related to the assessment of environmental impacts of aquaculture processes and the different available circular solutions, with a focus on the best options to valorize aquaculture side streams and how current regulatory burdens and gaps should be solved.

基于监管框架在欧盟水产养殖中引入循环经济原则的机会和限制

欧盟水产养殖只生产水产食品内部需求的一小部分，但推动这一活动必须符合环境保护和社会效益的高标准，正如欧盟最近推出的循环经济政策所推动的那样。然而，由于可用的工具和方法不同，对水产养殖和其他粮食生产系统的环境可持续性的评估很复杂。此外，当前的欧盟监管框架可能会限制实施某些循环解决方案的选择。本文研究了与水产养殖过程的环境影响评估相关的争议以及不同的可用循环解决方案，
