Androgenesis was the especial zoogamy that the germ plasma of offspring was from the agnate. In this study the eggs of Yellow catfish (Pelteobagrus fulvidraco) were irradiated by UV suspending in the synthetic ovarian fluid (OF), and the total dosage of UV irradiation was 220 mJ·cm~(-2). Diploid could be induced by heat shock (40℃, 2 min, 3 min) with different time period after fertilization (15-37 min). The result showed that heat shock with 2 min was better than 3 min; there were two apices of induction in 17-21 min and 27-31 min after fertilization. The highest hatching rate was 3.30% at 29 min after fertilization, and the difference between two apices of induction was unobvious.
