The growth and development of larvae and juveniles was morphologically investigated in Carassius auratus gibelio. The results showed that it took 52 h from fertilization to hatching at 22- 25 ℃. The newly hatched larvae had transparent body,with the head right near the yolk sac; the yolk sac accounted for 2 /3of larval volume,which was exhausted in the four-day-old larvae that started the exogenous nutrient period. The larvae were found to develop into juveniles from a few scales on the 20 thday after hatching to whole scales,fingerling,on the 28 thday after hatching. The relationship between total length( TL) and age in days( D)was described as: TL = 0. 001 2D3- 0. 038 8D2+ 1. 043 2D + 3. 945 8( r2= 0. 998). The relationship between body length( L) and body weight( W) of larvae and juveniles was expressed as: m = 1E- 05L3. 376 9( r2= 0. 982 7). The formula between body length and body height during the development of the fish was described as: H = 0. 000 1L3- 0. 028 4L2+ 1. 281 6L- 7. 250 5( r2= 0. 988 6). The findings provided the theoretical instruction for practical production of C. auratus gibelio.
