Recent developments in shrimp farming have mimicked natural aquatic environments for shrimps, known as aquamimicry, that provide a convenient, eco-friendly, pollution-free farming system. Aquamimicry refers to the application of natural conditions to enhance shrimp rearing and maintain water quality by creating phyto- and zooplankton blooms. A carbon source, such as wheat flour or rice bran, is fermented with probiotics to release their nutrients. Aquamimicry shares some similarities with biofloc technology, but there are also some key differences. First, the amount of carbon added to the system is reduced and does not depend on the nitrogen ratio; second, the deposited microbial masses are constantly harvested and used as food for other animals. First, the amount of carbon added to the system is reduced and does not depend on the nitrogen ratio; second, the deposited microbial flocs are constantly harvested and used as food for other animals. In its ideal state, the water would mimic the appearance and composition of a natural body of water that includes microalgae and zooplankton. As a result, feed conversion ratios have decreased, water exchanges have been minimized and diseases have been eliminated. It is believed that a variety of factors contribute to this, including better nutrition for the animal, a reduction of stress associated with fluctuating water quality, and minimizing environmental conditions that may favor the development of pathogens. In Aquamimicry, bioengineering or aquaculture takes place in harmony with microbial activity and the creation of a natural food source, and organisms re-establish a balance with the environment for green and sustainable aquaculture.
