Abstract: Brazilian aquaculture production is concentrated in continental fish culture, malacoculture and shrimp culture. This late, with a production of 65.1 thousand tons in 2016; mainly in Brazilian Northeast Region and specially at Ceará and Rio Grande do Norte states, where Penaeus vannamei is grown. The adoption of efficient cultivation systems has been essential, reducing the use of water resources, the emission of effluents and the transmission of diseases; culminating in an environmentally friendly activity. A balanced and cost-effective approach using probiotics is known as aquamimicry. The concept is based on the simulation of natural conditions, with zooplanktonic flowering for shrimp feeding and on the use of beneficial bacteria that guarantee water quality, using a carbono source fermentation; which releases nutrients in the water, such similar to bioflocs system. The simulation of a natural environment through aquamimicry system minimizes pH and dissolved oxygen flutuations, with no need of chemical products. Thus, the objective of this work is to evaluate the zootechnical and economic performance of P. Vannamei using the aquamimicry system. There were tested three diferente treatments: the first one using a commercial shrimp feed, the second using fermented soybean, and the last one using fermented soybean (70%) and wheat (30%) meals. The experiment was carried out at Fazenda Monólitos Aquacultura Ltda (Banabuiú, Ceará, Brazil). The results showed no statistical difference in zootechnical aspects. The operating costs per cycle of each treatment were R$31,127.82, R$23,681.20 and R$ 22,243.43, respectively. The difference found in operating costs influenced all projections and economic viability indicators. From the results, it can be concluded that the use of the aquamimicry system is viable both from a zootechnical and an economic point of view.
