Even so, the survival rate inside the rice-bran-handled biofloc was observed to generally be considerably reduce (27%) than that of the Regulate, which can have been because of the lack of carbon availability in the development of biofloc. Therefore, it is crucial to work with an proper carbon resource that is certainly ideal for farm environments and cultured organisms when using biofloc in fish culture. Haridas et al. [twenty] reported that biofloc noticeably improved the survival price of gray mullet, Mugil cephalus, especially in the nursery section.
