| Abstract: | For production enhancement and procedure upgrade, the developmental phases of laboratory-reared eggs of catfishPelteobagrus fulvidraco were investigated. Twenty mature females and 10 males were collected from Dadongmen wholesale fisheries market in Wuhan City
on May 8, 2003. Zygotes were stripped from mature fish after hormone-induced ovulation, fertilized, and incubated through
whole embryonic development. The fertilized eggs were stocked in density of 100 eggs/L in white square tanks of 10 L. Incubation
water was dechlorinated tap water with continuous aeration. The tanks were lit directly with 60 W fluorescent bulbs with a
12 light: 12 dark photoperiod. Water temperature, dissolved oxygen and pH were 29.0±0.5°C, 6.7±0.4 mg/L and 7.4±2, respectively.
The results showed that the eggs ofP. fulvidraco were yellow, sticky and contained much yolk. The mean diameter of fertilized eggs was 2.03 mm. At the water temperature of
29.0±0.5°C, the ontogenesis spent about 33 h after fertilization. From fertilization to hatching, the embryonic development
can be divided into 30–40 phases, which varies in the emphasis and direction of development. The detailed embryonic movement
was also described.
