[19] identified that the survival charges of C. gariepinus addressed with glycerol and sucrose-treated biofloc had been 90.six% and 76.3%, which have been noticeably higher than that from the Command team (sixty.0%). On the other hand, the survival level in the rice-bran-handled biofloc was uncovered being drastically reduce (27%) than that of the Command, which can have been because of the insufficient carbon availability while in the formation of biofloc. Therefore, it is important to use an correct carbon source that is definitely ideal for farm environments and cultured organisms when using biofloc in fish lifestyle. Haridas et al.
