Abstract
This study aims to determine the effectiveness of commercial probiotics (prod A, prod B, and prod C) on catfish growth, feed conversion ratio (FCR), and feed efficiency in catfish reared with a biofloc system. This study used a completely randomized design (CRD) with four treatments and three replications. The treatments used were APB, LOB, MSC, control, and three replicates. The results showed that the provision of commercial probiotics in catfish culture using biofloc gave a significant difference (P>0.05) to the daily growth rate and feed conversion ratio. The application of Prod A at a dose of 10ml/m3 on the media resulted in the highest productivity.
