Aquaculture sustainability is restricted by environmental drawbacks such as the pollution derived from the released organic waste. Integrated multi-trophic aquaculture (IMTA) aims to lower the input of this waste by culturing other species of low trophic level which feed on them. Despite the appealing idea of IMTA, its implementation is very limited in marine ecosystems. Focusing on marine fish farming, in general terms, fish farm waste is not expected to constitute a relevant food source for low-trophic level organisms cultured in the water column. We propose Regional Integrated Multitrophic Aquaculture (RIMTA) as a shift of paradigm in the way IMTA is used to sequester the dissolved exported waste and derived primary production generated by high trophic level cultures. RIMTA advocates for independent allocation of cultures of low and high trophic level species within the same water body. RIMTA implementation should be economically supported through tax benefits or nutrient quota trading schemes. Moving from IMTA to RIMTA should not only foster aquaculture sustainability but also the circular economy and the ecosystem services that the low trophic level cultures provide.

水产养殖业的可持续性受到环境不利因素的限制，例如因释放的有机废物而产生的污染。综合多营养水产养殖（IMTA）旨在通过养殖以其为食的其他低营养水平物种来减少这种废物的投入。尽管IMTA吸引人，但在海洋生态系统中其实施却非常有限。一般而言，着眼于海水鱼类养殖，预计养殖场废物不会构成水柱中养殖的低营养水平生物的相关食物来源。我们建议将区域综合多养水产养殖（RIMTA）转变为IMTA用于隔离由高营养水平养殖产生的溶解的出口废物和衍生的初级产品的方式的转变。RIMTA提倡在同一水域内独立分配低营养级别物种和高营养级别物种的文化。RIMTA的实施应通过税收优惠或营养配额交易计划得到经济上的支持。从IMTA过渡到RIMTA不仅应促进水产养殖业的可持续性，而且还应促进低营养水平文化提供的循环经济和生态系统服务。
