The treatments applied in this study were rearing the fish in biofloc with FR 5% and 8% of biomass per day, and rearing the fish with a FR of 8% per day without biofloc system as the control. Growth Promoter For Growth Promoter Probiotics Growth Promoter Probiotic For Biofloc Fish Farming. Sea and rivers are the main and major source of fish. Compared to the control group, the growth of prawns was not affected even though the zero-exchanged water was used in the biofloc groups. Data on capture fishery, fish processing business and fish farming were tabulated and analyzed using descriptive method. Water quality parameters were stable and not influenced by the stocking densities tested. Growth rate, feed intake, feed conversion efficiency (FCE), and stomach evacuation rate were significantly influenced by temperature and fish size. There was a great market opportunity for featherback chips in this area of study, where the demand of fish chips (36 tons/year) was six times higher than the supply to the market (6 tons/year). The fish samples were in good condition and grew negatively allometric (b=2.7766-2.8791). Stocking was at 37 prawns m− 2 (0.025 g− 1) and fed twice daily with a commercial diet. Call +91-8047023361.

Furthermore, the relative gene expression levels of prophenoloxidase (ProPO), catalase (CAT) and superoxide dismutase (SOD) of prawns in the biofloc groups were significantly higher than that in the control group during the acute H2O2 and pH stress (P < .05), as well as the relative gene expression of crustin (CRU) in the biofloc groups was higher than that in the control group during the H2O2 stress (P < .05), which exhibited a stronger adaptive antioxidant and antibacterial response in prawns reared with biofloc, thereby a higher relative percent survival of prawns was recorded in the biofloc groups during pathogen challenge test. ... VIETNAM SAKAN TECHNOLOGY DEVELOPMENT AND INVESTMENT JOINT STOCK COMPANY. Economic analysis revealed that a significantly higher (P<0.05) cost-benefit ratio was obtained in the Caged Perch treatment. The biofloc volume dynamics in the water showed that carbon addition significantly promoted the biofloc formation in all biofloc groups (P < .05), meanwhile, during the 45-day rearing period, biofloc improved water quality by consuming the element N accumulated in the water, then leading to the decrease in the concentration of TAN and NO2−-N.
