Abstract
This study was carried out to investigate the effect of artificial diet and live food on eyed egg stage rate and hatchability of eggs of broodstock mandarin fish (Siniperca scherzeri) for 10 months. Two groups (five fish per group) of fish with mean body weight of 892±65.7g (Mean±SD) were fed either artificial diet (commercial Japanese eel diet) or live food (crucian carp and common carp juveniles), respectively. Fish were cultured in running water culture system in which water temperature was kept at 3.9±0.4°C to 23.5±1.7°C. Averaged eyed egg stage rate (74.5±4.7%) and hatchability (68.6±1.1%) of eggs for broodstock mandarin fish fed artificial diet were significantly higher (P<0.05) than those of fish fed live food (eyed egg stage rate; 57.3±4.4%, hatchability; 51.8±3.3%).
