Necessity of Health supplements – To keep up C:N ratio, alkalinity, together with other factors increase suitable health supplements like sugar molasses, liming content, etcetera. The beginning-up time period is needed – Biofloc technology demands an initiation interval for that microorganisms to be active and function properly.

Which is why There exists a insufficient oxygen with the fish. Dissolved oxygen on your own can not satisfy the wants of many of the fish in the tank.

Mansour and Esteban [28] reported a significant increase in WBCs in O. niloticus cultured in biofloc, which was a result of a rise in leukocytes due to there getting far more neutrophils and lymphocytes. This raise was induced by the upper protein stages while in the biofloc natural environment. Other authors have also reported major improves in WBCs in C. gariepinus and Asian stinging catfish, Heteropneustes fossilis, when cultured in biofloc, suggesting that it results in a better immune capability and much better well being in fish [19,38]. However, many experiments confirmed possibly no adjust or even a reduce in several fish lifted with biofloc, and many recommend that there was no effect on well being.
