SGR is calculated using the method SGR(%) = LOG e ultimate bodyweight from the fish – Log e Original body weight of the fish/ number of times x one hundred. PWG is calculated utilizing the formulation PWG(%) = Remaining excess weight with the fish- Original excess weight/ Original bodyweight x 100. FCR is decided by dividing the dry feed weight given via the damp weight on the fish.
Using Biofloc technology helps to enhance drinking water and land use premiums. It lowers environmental effects. It is a confined or zero h2o Trade system.
यही वजह है कृषि विशेषज्ञ मछली पालकों को अक्सर बायोफ्लॉक तकनीक अपनाने की सलाह देते हैं.
In this post, We are going to delve in to the essentials of starting up a biofloc fish farming operation. From understanding the idea of biofloc technology to creating your farm, We'll go over every one of the very important factors. So, let’s dive in!
With Biofloc, we can easily recycle this waste again into feed and decrease the costs of significant protein feeds. Biofloc systems make improvements to fish wellbeing as well as lessen the unfold of pathogens.
Nevertheless, fish species which include tilapia and carps, and shrimps for example pink, brine, and pacific whiteleg shrimp which might be physiologically tailored to digest microbial protein acquired from biofloc use usually are well suited for biofloc systems (Emerenciano et al. 2013; Hargreaves 2013). Quite the opposite, biofloc systems are usually not ideal for fish species for instance channel catfish and hybrid striped bass and also for prawns for example large tiger prawn and huge freshwater prawn. They can not tolerate minimal drinking water good quality mainly because of the substantial focus of solids (Hargreaves 2013; Panigrahi et al. 2019a). Biofloc is produced by adding natural and organic carbon and superior aeration, which lessens poisonous dissolved nitrogen inside the h2o, the place inside waste cure procedures are emphasised and encouraged (Liu et al.
The flocs are rich in protein and provide fish and shrimp with a good source of vitamins and phosphorus. Farmers have also reported higher efficiency indicators With here all the system in comparison with regular aquaculture tactics.
Simultaneously, the remaining 75% goes to the water and contributes to the growth of unwelcome aquatic weeds or algae. Accumulating waste feed and nitrogenous wastes in water lessens its oxygen amount and necessitates changing h2o in typical aquaculture.
Moreover, the manufacture of biofloc might also function a possible source of protein for animal feed, decreasing the demand from customers for soybean and fishmeal. By using sustainable biofloc fish farming tactics, farmers can strengthen their base line whilst contributing to your preservation of our organic assets.
Lower Production Cost: Biofloc fish farming is really a reduced-cost method of fish farming, mainly because it reduces the need for expensive professional fish feed. The fish are fed with a mixture of business fish feed and protein-abundant biofloc, which cuts down the cost of fish feed.
Together with these aspects, producers must actively manage biofloc ponds to prevent nitrite accumulation and to keep alkalinity stages remaining inside a balanced selection.

एरिएटर बायोफ्लॉक सिस्टम का महत्वपूर्ण हिस्सा होता है। यह पानी में ऑक्सीजन का प्रवाह बनाए रखता है, जिससे मछलियां स्वस्थ रहती हैं और सूक्ष्मजीव सक्रिय रहते हैं।
A normal pond usually uses paddle-wheel aerators. A Biofloc system requires about six milligrams of oxygen per liter for each hour, and at least 30 horsepower aerators for every hectare is recommended to begin with. Paddle-wheel aerators must be set up strategically to make a current while in the pond.
