The present study demonstrates that manipulating the carbon-to-nitrogen ratio significantly affects various parameters of common carp growth and also influences the culture system. The composition and nutritive value of the biofloc system can be significantly influenced by the carbon-to-nitrogen (C: N) ratios. Higher C/N ratios generally promote faster nitrogen removal since heterotrophic bacteria regenerate more quickly compared to photoautotrophic microalgae. This may result in increased biofloc production. A C:N ratio of 20:1 was found to be effective in maintaining water quality and the biofloc culture system compared to ratios of 15:1 and 10:1. Furthermore, the 20:1 C:N ratio was beneficial for weight gain and length gain of common carp during different observation periods. Proximate composition and floc volume measurements were also maximized in treatment group T3 compared to T2 and T1. Consequently, treatment T3 was determined to be the optimal C:N ratio for the biofloc system, ensuring better growth conditions and system maintenance.
