Seed fish (toddlers) transported from distant for being place into tanks require a lot more treatment as they are underneath stress. Sufficient food must be provided. Prevent feeding excessive, or even the fish may perhaps die. Fish don’t create overnight. A farmer need to Wait and see to make superior funds.

Lower stocking densities manufactured bigger fish, but expansion inside stocking densities was comparable in between Manage and Biofloc treatment plans.
The compartmental design would give farmers greater Command in excess of the manufacturing procedure, guaranteeing that their investments in biofloc translate into higher yields.
From this issue, monitoring the pond water, using standard drinking water samples, and figuring out the general performance of the two types of Biofloc technology as well as their respective densities are vital. Simply put, outdoor Biofloc is made of inexperienced algae and brown micro organism: the algae generally use sunlight for his or her advancement, though the microbes mostly use leftover foods, their by-items, and affiliated waste.
बायोफ्लॉक मछली पालन के लिए आवश्यक सामग्रियाँ और उपकरण
स्नान समय की देखभाल: रोहू और कतला को ठंडे पानी में अधिक आराम मिलता है, इसलिए पानी के तापमान की विशेष निगरानी आवश्यक होती है।
It decreases the pressure around the environment by blocking the discharge of waste products into drinking water bodies. It is usually a profitable way of intense fish farming, as it makes proteinaceous feed in situ, lowering dependence on fish oil and food items.
A simple mixture of rice bran or polishing and any in the get more info oilseed cakes available in Punjab can be utilized.
बायोफ्लॉक में सूक्ष्मजीवों की उपस्थिति मछलियों के पोषण में सहायक होती है, जिससे मछलियों को चारे की कम आवश्यकता पड़ती है। बायोफ्लॉक सिस्टम में प्राकृतिक रूप से उत्पन्न होने वाले फ्लोक्स मछलियों के आहार के रूप में कार्य करते हैं, जिससे फ़ीड की लागत में उल्लेखनीय कमी होती है।
No important change in temperature, complete ammonia nitrogen, whole phosphorus and NO2-N; lowered pH and dissolved oxygen
With appropriate management, it is achievable to attain large output yields when compared to regular farming procedures.
There are plenty of weaknesses inside the biofloc system, such as the urgent require for high aeration and water motion, which ends up in the amplified Electricity prerequisite for mixing and aeration. On top of that, various negatives may also be reported for BFT, including reduced response time due to consumption of dissolved oxygen within the water and better respiration premiums, likely air pollution from nitrate accumulation, plus the requirement of begin-up period and alkalinity supplementation (Reddy 2019).
Additional fish and shrimp farmers are adopting biofloc technology to sustainably scale-up production, but unanswered questions on microbial dynamics have researchers warning that the method could be unsuitable for sure fish species.
