बायोफ्लॉक सिस्टम में मछलियों को अतिरिक्त चारे की आवश्यकता कम होती है, क्योंकि सूक्ष्मजीव फ्लोक्स के रूप में उन्हें पोषण प्रदान करते हैं। लेकिन मछलियों की तेजी से वृद्धि के लिए फीड (चारा) की गुणवत्ता भी महत्वपूर्ण होती है।
बायोफ्लॉक मछली पालन के लिए आवश्यक सामग्रियाँ और उपकरण
Good aeration: Oxygen is important for fish survival, and aeration systems should be correctly designed and taken care of to be certain satisfactory oxygen amounts.
Research have proven that biofloc systems can enhance fish generation by up to 30% as compared to common solutions. Furthermore, biofloc technology can reduce drinking water use by as many as 90% and decrease the necessity for antibiotics together with other chemicals.

पानी में दूषित पदार्थों को हटाने और साफ पानी बनाए रखने के लिए फिल्टर का उपयोग किया जाता है। बायोफ्लॉक में, फिल्टर का चयन बहुत ध्यानपूर्वक करना होता है क्योंकि यह पानी में बैक्टीरिया की संख्या को नियंत्रित करता है।

Various shrimp species thrive in biofloc culture Numerous scientific studies have shown that bottom-dwelling species like shrimp and tilapia are most effective suited to biofloc creation.
In addition to these variables, producers should actively take care of biofloc ponds to stop nitrite accumulation and to help keep alkalinity concentrations remaining in a balanced assortment.
Blood glucose concentrations are used by Organic systems as A vital fuel to improve muscle mass activity, and glucose is a vital indicator in assessing acute stress, as glucose ranges improve when tissues such as the brain, gills, and muscles improve respiration to cope With all the increased Vitality calls for of worry [56]. Inside a stress filled atmosphere, anxiety hormones for instance cortisol and catecholamine are released as a Major reaction in fish, with glucose generation being a secondary response [fifty seven]. Shourbela et al. [forty seven] confirmed the plasma glucose of O. niloticus cultured with biofloc comprised of numerous carbon resources such as glycerol, molasses, and starch was substantially diminished, meaning that worry degrees were being lower within the fish in biofloc in comparison to the Handle group. Verma et al. [45] also found out a minimize in plasma glucose concentrations here in Rohu, Labeo rohita, when it had been cultured with biofloc created from many carbon resources which include tapioca, wheat, corn, and sugar bagasse, they usually advise that this was as a consequence of a lessen in cortisol and glucose a result of the significantly less nerve-racking biofloc surroundings.
Adineh et al. [32] reported a big increase in serum ALP of C. carpio cultured with biofloc and suggested that the rise in enzymatic activity was because of the stimulated immune exercise induced via the biofloc atmosphere. In the course of a stress reaction, cortisol secretion from interrenal cells in The top kidney is activated by corticotropin-releasing aspects through the secretion of adrenocorticotropic hormone through the anterior pituitary, and this is a major indicator of worry in fish [seventy one]. This cortisol raise results in phagocytic and complement action suppression in blood and head-kidneys, a lower in the volume of lymphocytes, and a rise in susceptibility to an infection [72]. Almost all of the scientific tests confirmed a substantial decrease in serum cortisol in fish cultured with biofloc, and it absolutely was argued this lessen was the result of proving that biofloc had an effect of relieving worry in fish [thirty,32,34,47,55,58]. Verma et al. [forty five] also reported a big reduce in serum cortisol in L. rohita cultured with biofloc, suggesting that biofloc experienced an anti-pressure effect on fish.
H2o procedure: Good incoming h2o cure can lower the chance of introducing pathogens or contaminants to the fish farm.
