[19] located that the survival costs of C. gariepinus dealt with with glycerol and sucrose-taken care of biofloc had been ninety.6% and seventy six.3%, which had been noticeably better than that of your Manage group (60.0%). Even so, the survival level while in the rice-bran-dealt with biofloc was uncovered being drastically lower (27%) than that on the Management, which may are actually due to the lack of carbon availability while in the development of biofloc. For that reason, it is crucial to employ an ideal carbon source that may be ideal for farm environments and cultured organisms when utilizing biofloc in fish tradition. Haridas et al.
