Biofloc fish farming

Biofloc fish farming technology is a very innovative and affordable system in which harmful, toxic materials such as Nitrate and Ammonia can be converted into proteinaceous feed at low costs. Biofloc system was developed to maintain a pollution control over the aquatic animal production. The availability of water is a limiting factor of the total production cost of fish farming and biofloc wastewater management is the perfect solution for the dilemma. The principle of the technique is the generation of Nitrogen by maintaining a higher concentration of Carbon : Nitrogen ration and thereby acquire the dual advantages of effective waste management as well as the production of proteinaceous feed to the fish.

The working of biofloc system can be explained briefly as follows: Heterotrophic bacteria is the main component of the biofloc system. The heterotrophic bacteria consumes the nitrogenous waste (ammonia) produced by the fish and inturn converts them into protein which can be used for the growth of the fish itself.


The good nutritional value found in biofloc is an added advantage which is a good source of minerals and vitamins, especially phosphorus. The soyabeen or fishmeal present in the feed can be replaced by the dried biofloc ingredient.

The above mentioned statements clearly points out the fact that biofloc fish farming is the most cost effective and nature friendly way of fish farming. The essential components such as water and land are used in the most efficient way in biofloc. Higher productivity and higher biosecurity ensures the profit. The use of cheap fish food or trash fish for fish feed formulation is not at all needed here. Altogether the biofloc fish farming technology is a burgeoning system in which people are willing to invest more and more as the days pass by. It is the easiest way to earn more profit with the addition of minimal input.
