| Abstract | To evaluate water quality and growth performance of butter catfish under temperature manipulation, 15 fish werecultured in 16 fiberglass tanks for ten weeks in three temperatures of 29 ?C, 31 ?C, 33 ?C, and in ambient temperature as control(25.1-29.5 ?C). The growth performance and water quality parameters (temperature, DO, pH, TAN and NO2-N) in culture wereinvestigated. Water quality seemed not to be controlled by temperature but by feed consumption. DO concentration decreased(8.27+0.10 mg/l) in the 33 ?C tank (P<0.05). Growth of catfish performed well in all treatments except fish in the 33 ?C tank, inwhich the percentage weight and length gain declined (479.70+86.64% and 73.85+10.52%, respectively) (P<0.05), and bothSGR and feed intake significantly decreased (2.55+0.26 %/day and 194.28+42.40 g, respectively) (P<0.01). FCR and survivalwere positive in every temperature exposure (P>0.05). Results reveal that the maximum thermal tolerance for growth is best inwater temperature which does not exceed 31 ?C. |
