Fig. 1.

Quarterly market prices of gibel carp (Carassius auratus gibelio ♀ × C. carpio ♂) in recent six years (¥ kg-1). The data were obtained from weekly marketing investigation each month, and then expressed as the mean ± standard deviation (SD).

Fig. 2.

Nitrite-N (NO2-N) dynamics in the biofloc technology (BFT) system and control group during 60-day experimental period. The data were expressed with the mean ± SD.
