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।
क्यों तिलापिया बायोफ्लॉक के लिए उपयुक्त है?
Blood within the circulatory system serves various features inside the survival of fish, and hematological parameters are critical indicators for evaluating their physiological state, worry, immune responses, and disease resistance, and also reflecting the nutritional and environmental conditions, therefore detecting abnormalities linked to fish health position [38]. Biofloc can contribute to the improvement in the wellness of fish on account of each its digestive enzyme activity and physiological exercise, and the analysis of hematological parameters really should be a superb indicator to verify its efficacy [eighteen]. Hematological and biochemical parameters of fish species elevated in biofloc are shown in Desk three. Erythrocytes are by far the most considerable mobile elements from the circulatory system of fish, taking part in essential roles in fuel exchange plus the respiration of cells, together with carrying out various functions linked to immunity, for example antiviral responses, phagocytosis or cytokine-mediated signaling [forty six].

The need for seafood use is escalating with the populace, bringing about a increased demand from customers for aquatic merchandise for industrial use.
Biofloc technology is really an revolutionary and efficient microbial biotechnology through which harmful supplies such as nitrogen elements might be dealt with and transformed to a beneficial product or service like proteins, that may be used by the fish and crustaceans as supplementary feeds. It is an excellent approach to produce the aquaculture system underneath confined or zero h2o Trade with high fish stocking density, vigorous aeration, and biota formed by biofloc.
Hematocrit and hemoglobin are each vital indicators for assessing fish well being [fifty one,52]. Mansour and Esteban [28] reported an important rise in hematocrit in O. niloticus cultured with biofloc made from carbon sources of rice bran and wheat-milling by-products, but there was no significant alter in biofloc made with glucose as being a carbon resource. The majority of the studies on the other hand did not show variations in hematocrit, indicating that the biofloc system did not adversely influence the hematological Qualities of fish. The most crucial function of hemoglobin is to move oxygen through the gas Trade organ to peripheral tissues, in addition to a minimize in hemoglobin underneath strain problems may be manifested by a minimize in the rate of hemoglobin synthesis, leading to impaired oxygen source to your tissues and sooner or later resulting in a lessen in RBCs through hemolysis [fifty three,54].
