| Özet |
| In this study, the use of biofloc technology (BFT) in crayfish culture for 32 days was tested. Two groups (initial total lengths, TLi and weights, Wi measured) within 3 replications were planned as BFT application group (TLi: 112.17±0.99 mm, Wi: 37.61±0.97 g) and control group without BFT (TLi: 112.22±0.94 mm, Wi: 37.61±0.87 g). Six crayfishes were stocked in each tank with a volume of 80 L (70x40x30 cm). In the experiment, molasses was used as a carbon source in BFT application. Carbon/Nitrogen ratio was optimized at 15. All tanks were continuously aerated. Crayfish were fed 3% of body weight twice a day (12h light-12h dark). At the end of the experiment water quality parameters were measured (for BFT application group T: 20.2±1.1°C, saturation: %70±1.0, dissolved oxygen: 6.2±0.8 mg L-1, pH: 7.6±0.7, PO4:0.5±0.1 mg L-1, N-NO2-:0.1±0.1 mg L-1, N-NO3-:2.0±0.1 mg L-1, salinity: 0.002 ppt and for the … |
