BioFloc- An overview!

Biofloc technology (BFT) is an innovative and eco-friendly fish farming technique that involves stock-breeding of fishes, in a micro-organism rich ecosystem, artificially created in a tank.<br>The term Biofloc (Bio=life, Floc= aggregate) refers to clusters of micro-organisms such as bacteria, fungi, algae, protozoa, and other kinds of organic particles like fish faeces and uneaten feed. All these, together, form loose clusters of organic matter which are held together by a thin film-like substance. <br>Ecosystems rich in Biofloc enable recycling of the waste from the fishes into an organic feed. This not only serves as a protein-rich source of food for the fishes but also maintains the optimum Carbon: Nitrogen ratio, which is a pre-requisite for viable production.<br>The best part is, the process involves a zero to minimal water exchange within the ecosystem. This reduces the chances of water contamination and ensures a high level of bio-security.<br>BFT was invented by Prof. Yoram Avnimelech, an Israeli environmentalist in the u201970s to promote a more sustainable mode of fish farming. In the past few decades, Biofloc has become increasingly popular all across the world, including India.<br>
