Dauda et al. [19] discovered which the survival premiums of C. gariepinus dealt with with glycerol and sucrose-treated biofloc were being ninety.6% and 76.three%, which have been noticeably bigger than that from the Command team (60.0%). Nevertheless, the survival price inside the rice-bran-treated biofloc was identified for being drastically decrease (27%) than that of your Command, which may have been due to deficiency of carbon availability from the formation of biofloc. For that reason, it is important to use an ideal carbon source that is certainly appropriate for farm environments and cultured organisms when utilizing biofloc in fish tradition. Haridas et al. [twenty] reported that biofloc considerably improved the survival level of grey mullet, Mugil cephalus, especially from the nursery stage.
