Lastly, to circumvent ammonia peaks later on while in the manufacturing system, this step also needs to be repeated, particularly when substantial stocking densities are used together with substantial amounts of artificial feeds. 

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 get more info उत्पन्न होने वाले फ्लोक्स मछलियों के आहार के रूप में कार्य करते हैं, जिससे फ़ीड की लागत में उल्लेखनीय कमी होती है।
