four. Probiotics or Germs – Microorganisms make Biofloc fish farming distinctive from conventional fish farming. The bacteria used in Biofloc are heterotrophic. They feed on fish waste items, like feed waste. Employing fish squander maintains poisonous ammonia levels in the tank.
The biofloc farming system is really a technology that manipulates the setting by depending on oxygen supply and utilizing microorganisms, which immediately contribute to enhancing the digestibility of fish feed. With regards to land area ratio, just one biofloc device measuring ten cubic meters can be employed for breeding one,000 fish.
BFT presented aquaculture being a sustainable Resource with the environmental, social, and economic problems that synchronize with its growth. So This method ought to be developed by a lot more researches to help keep up and maintain the aquaculture systems Down the road.
2012). It absolutely was reported the optimum ratio of carbon and nitrogen in biofloc could aid to maintain the drinking water good quality to lift Pacific white leg shrimp in lower salinity for inland tradition. In turn, it decreases the possibility of land air pollution by the release of saline wastewater within the shrimp pond (Kumar et al. 2019). In addition, the biofloc engaged on improvement from the physicochemical parameters of water into the optimum array is important for the appropriate advancement of fishes and shrimp (Sharma et al. 2018). A study reported that mullet (
It's also much easier to explain to if a recirculating aquaculture system is not really Performing effectively because the color of your h2o will adjust.
Feeding: The fish in biofloc fish farming are fed with a mix of economic fish feed and biofloc. The biofloc is harvested from the tanks and fed into the fish. The amount of biofloc fed for the fish really should be altered dependant on the scale and number of fish within the tank.
activity, this hasn’t been observed in all studies. The scientists note that in a few trials, microbial flocs have contained elevated vibrio
Need of continuous energy offer and Electricity costs – It is necessary to function aeration devices together with other equipment; loss of energy is unsafe because it lowers drinking water high-quality. Necessity of Dietary supplements – To keep up C:N ratio, alkalinity, along with other aspects increase applicable health supplements like sugar molasses, liming substance, and so forth. The beginning-up time period is necessary – read more Biofloc technology desires an initiation time period to the bacteria to be active and performance thoroughly. What are the requirements for Biofloc fish farming?
हां, बायोफ्लॉक सिस्टम पर्यावरण के अनुकूल है क्योंकि इसमें पानी का पुनः उपयोग होता है और अपशिष्ट को पोषण में बदल दिया जाता है। इससे जल संसाधनों की बचत होती है और प्रदूषण भी कम होता है।
इसी तरह की एक तकनीक है बायोफ्लॉक. इस तकनीक के जरिए किसान अधिक मछलियों का उत्पादन कर बंपर मुनाफा कमा सकते हैं.

फ़ीड की आवश्यकताएँ: उन्हें कम प्रोटीन युक्त चारा दिया जा सकता है, क्योंकि फ्लोक्स ही उनका मुख्य आहार होता है।
बायोफ्लॉक में सूक्ष्मजीव पानी की गुणवत्ता को नियंत्रित करते हैं, जिससे मछलियों की मृत्यु दर कम होती है।
बता दें रोजाना मछलियों के लिए पानी बदलना बेहद मुश्किल प्रकिया है. इस तकनीक के आने से किसानों को इस तकनीक से छुटकारा मिल सकता है. इसके अलावा मछलियों के प्रोटीन पर मछली पालकों को अलग से खर्च नहीं करना पड़ता है.
