Use of a bacterial preparation in the formation of a bacterial composition in Biofloc technology

This study is devoted to investigating the possibilities of intensive cultivation of African catfish (Clarias gariepinus) using bioflick technology under the conditions of Uzbekistan. The experiment was conducted in 700-liter tanks, and the bacterial preparation “Doctor Robik” was used to form activated sludge, or biofloc. During the study, the bacterial composition of the water was identified, and the presence of Citrobacter freundii, Fictibacillus barbaricus, and Plestiodon’s shigelloides was recorded. The results showed that two of these bacteria had beneficial effects, while one had a negative effect, indicating the risk of uncontrolled bacterial proliferation in the biofloc system. Therefore, the formation of a positive bacterial composition in biofloc systems is of particular importance.
