Biofloc Technology Water Quality Management In Aquaculture

At its core biofloc is a waste water treatment system and was developed to mitigate the introduction of diseases into aquaculture facilities or farms from incoming water water exchange typically used in prawn farming. It is an excellent.

Biofloc technology water quality management in aquaculture. Biofloc Technology is a technique of enhancing water quality in aquaculture fish farming through balancing carbon and nitrogen in the system. Water quality parameter such as ammonia which is one of the most toxic inorganic compounds that are produced in water can only be removed by bacterial activity through conversion into a less toxic. Biofloc technology for water quality management in aquaculture Saraswathy R Muralidhar M A Panigrahi N.

Biofloc technology has gained attentions recently as a sustainable and eco-friendly method of aqua-culture which controls water quality along with the production of value added. Although there is published data on pond-reared catfish fillet mineral concentration data on mineral content of catfish grown in the BFT system is lacking. In summary biofloc technology is able to ensure maintenance of water quality through uptake of ammonia to produce microbial proteins and it also makes available food for the cultured fish through utilization of the microbial protein produced hence increased efficient utilization of feed supplied decreased food conversion ratio and decreased the cost of feeding in aquaculture.

Biofloc Technology BFT is considered as new blue revolution since nutrients can be continuously recycled and reused in the culture medium benefited by the minimum or zero-water exchange. Panigrahi 64-67 11 Aeration requirements in biofloc based shrimp culture systems M. Low cost sustainable and environment-friendly technology for large-scale adoption.

In addition to mineral accumulation in intensive recirculating aquaculture system RAS water minerals may bioaccumulate in culture animal tissue particularly edible tissue. It also provides practical information about the approaches and treatments that can be used to enhance water quality in aquaculture systems. One of the systems that enable intensification at a relatively reasonable investment and operating cost is biofloc technology.

Daily monitoring of water parameters will ensure the quality of biofloc is at its optimum. Biofloc technology is a technique of enhancing water quality in aquaculture through balancing carbon and nitrogen in the system. Biofloc technology is based upon pond management using minimal water exchange and subsequent development of dense microbial populations.

Biofloc technology BFT is considered the new blue revolution in aquaculture. The biofloc fish farming materials system was developed to improve environmental control over the development of aquatic animals. The most influential factors in aquaculture are feed costs and the most limiting factor is waterland supply.

This handbook discusses background information from chemistry physics biology and engineering necessary for understanding the principles of water quality management in aquaculture. Biofloc technology helps to control water quality which is essential for the success of the growing cycles. Biofloc systems employ a counter-intuitive approach to more traditional aquaculture designs.

BFT is an environment friendly aquaculture technique based on in-situ microorganism production. Bio-floc act as a substitute for fish meal in aquaculture feed. RAS and biofloc both involve water quality monitoring but they are slightly different in the parameters.

The technology has gained the attention of the world as a good method to control water quality with the added value of producing protein-rich feed. The protein level in bio-floc ranges from 15 to 20. The technology has recently gained attention as a sustainable method to control water quality with the added value of producing proteinaceous feed in situ.

This latest technology is available at a cheap cost and has low technical demands which makes it the fish farmers top choice. Negligence in monitoring the water quality parameters might bring to a big loss to the farmers. Water quality is important in any aquaculture production.

It is essentially a water quality management techniques through manipulation of microbiota to convert the deleterious waste from aquaculture production to consumable body biomass and it has been established to have many other benefits asides from the intending water quality. Biofloc Technology is the new blue revolution in aquaculture which ensures sustainable production by breeding fish using minimum resources like feed water and land and thus preserving the nature. High stocking rates and aquatic animal rearing need wastewater treatment.

Reduced need for water exchange. Bio-floc system provides a protective shell to the fish through a probiotic effect Depression of Tilapia infection by Streptococcusbacterial problem.
