sources on the biofloc system and its influence on Penaeus vannamei culture. Four
sources of carbon viz. Tapioca flour (BFTf), Rice bran (BFRb), Wheat flour (BFWf), Rice
Flour (BFRf), and biofloc were generated, the absence of CHO being considered as
control (C). The experiment was carried out in 100L FRP tanks in triplicate, and the
post-larvae (ABW: 0.11 g) were stocked @ 400 PL/m3
. Results revealed that the
addition of complex carbon sources effectively reduces the TAN by 62-67%. The
average body weight of shrimp in the rice flour and wheat flour treatments were
significantly higher compared to control. Similarly, improved survival was observed in
rice bran treatment (89%). Beneficial bacteria were isolated from all the treatments as
well as control. Real-time analysis revealed significantly (P<0.05) higher expression of
digestive enzyme-related genes compared to control the utilization of carbohydrates,
exhibiting an encouraging trend. The complex carbon sources (BFRf) and (BFWf) have
been effectively utilized, resulting in improved water quality, microbial diversity,
growth performance, and enhanced digestive enzyme activity.Not Availabl
