The effect of production of blue morph, Pseudotropheus saulosifry in biofloc technology was examined concerning the growth performances and survival rate. Water quality and growth tests were done with fry that was harvested from the biofloc and control. The physicochemical water quality parameters were checked periodically. Of this, the water temperature and nitrite had a statistical significant. The concentration of nitrite was significantly lower in the biofloc (0.08 ± 0.12 mg/L) than the control (3.57 ± 0.23 mg/L)and as similarly ammonia that means 3.56 ± 0.24 mg/L in biofloc and 4.53 ± 0.29 mg/L in control but no statistical significance. The growth performance was affected passively by the biofloc technology and had a statistical significance at 1 percent level. A greater specific growth rate (%/day) of 3.58 was noticed in biofloc, but the lower of 3.35 was in control. This study concludes that the biofloc had better water quality condition as well as improved growth performance when it compared to control. [ABSTRACT FROM AUTHOR]
