Aquamimicry: New an innovative apporoach for sustainable development of aquaculture

Abstract

Aquamimicry is an innovative technology can be efficiently employed to achieve sustainable aquaculture. It is mimicking the natural environment of organisms in a confined water conditions. The technology utilized the heterotrophic fauna rather than autotropic organisms. In this system suitable carbon ingredients (energy source) along with probiotics are added, which helps to utilize the unutilized nitrogen, generated through feed and excreta and finally converted to floc and help to maintaining the population of copepod as a source of proteinaceous feed. Aquamimicry is more or less similar to bio floc technology except few differences like the quantity of carbon source and the dominated communities are zooplanktons like copepod that will serve as supplemental nutrition to the cultured shrimp or fish and less feed input compare to bio floc technology. Further aquamimicry can be adopted in extensive and intensive system of farming with in the limited supply of aeration whereas, bio floc technology required a specialized management and heavy aeration provisions and mainly used in intensive systems. Feed accounts for more than half the production cost in most aquaculture practice and in aquamimicry system live feed (copepods) are generating within the system by adding suitable carbon sources which not only reduce the dependency on the supplementary feed but also help to maintain the good water quality and health of the organisms. Therefore, aquamimicry can be considered as an efficient technology which can reduce the production cost more sustainable manner and give better yield to the farmers.
