FCR is decided by dividing the dry feed bodyweight presented from the moist bodyweight of your fish.
The biofloc farming system is often a technology that manipulates the setting by relying on oxygen source and utilizing microorganisms, which specifically add to enhancing the digestibility of fish feed. Regarding land space ratio, a person biofloc device measuring ten cubic meters can be used for breeding one,000 fish.

Biofloc can add to the development of your wellbeing of fish resulting from equally its digestive enzyme activity and physiological exercise, and the evaluation of hematological parameters should be a great indicator to substantiate its efficacy [eighteen]. Hematological and biochemical parameters of fish species raised in biofloc are demonstrated in Table three. Erythrocytes are probably the most ample cellular factors during the circulatory system of fish, playing vital roles in gas exchange as well as respiration of cells, together with undertaking several features associated with immunity, for instance antiviral responses, phagocytosis or cytokine-mediated signaling [46].
