SGR is calculated using the components SGR(%) = LOG e closing bodyweight from the fish – Log e initial excess weight in the fish/ range of days x one hundred. PWG is calculated using the components PWG(%) = Remaining weight with the fish- Preliminary bodyweight/ Original pounds x a hundred. FCR is set by dividing the dry feed excess weight provided from the wet excess weight of the fish.
The flocs by themselves are protein-loaded and supply fish and shrimp with a fantastic supply of nutritional vitamins and phosphorous. The authors describe that letting the microbial flocs to proliferate can make improvements to water top quality and immobilise harmful nitrogen.
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।
The authors counsel that producers undertake a shut administration system for biofloc ponds. A compartmental design – where by fish production and microbial proliferation happen in independent spaces – could make handling biofloc systems less complicated.
If ammonia concentrations turn out to be significant, it can result in fish kills. In addition, micro organism also transform a few of the waste into protein cells. This protein cell serves as foods for fish. Bacterial figures are maintained by incorporating carbohydrates and molasses In the tanks. They go on their perform of cleaning the h2o in a more quickly fee.
Lowered full suspended solids; active heterotrophic bacterial assimilation and nitrification; Improved amounts of NO–3 and overall nitrogen
Immediately after being broadly adopted through the Local community, the fish farming system that satisfies the aspects of sustainable fisheries faced many difficulties due to high creation costs, including:

The bacterial advancement (flocs) could consume nitrogenous fish wastes and poisonous metabolites prior to being eaten through the cultured species. This would scale back both of those the environmental footprint of generation and feed costs.
Paddle-wheel aerators really should be strategically put to produce a present-day inside the pond. You must also shift some aerators consistently to make certain reliable particles don’t settle in very little or low-quantity parts.
Along with these elements, producers should actively deal with biofloc ponds to avoid nitrite accumulation and to help keep alkalinity ranges remaining inside a healthy assortment.
A costly drinking water exchange system replaces contaminated h2o with clean water in open pond fish farming. Normally, exposure of fish to pathogens and poisonous organisms and condition outbreaks causes economical reduction to farmers. Biofloc systems use probiotics or microorganisms that encourage certain immunity in species and lessen pathogenic micro organism.
The h2o is additionally treated with probiotics, which can help to make an setting that biofloc fish farming profit per tank is conducive to The expansion of beneficial microorganisms.
सिस्टम को सुचारू रूप से चलाने के लिए एरिएटर का नियमित निरीक्षण और रखरखाव आवश्यक है। इससे पानी की गुणवत्ता बनी रहती है और मछलियों का विकास बेहतर होता है।
