| Abstract: | Heat shocks effectively produced triploids inPenaeus chinensis. Fertilized eggs heat shocked (28–32°C) for 8 to 16 minutes, starting from 8 to 20 minutes after spawning, resulted in triploidy
induction rates of 39%–75%. Several triploid populations were cultured to 10 cm. In a triploid population, two kinds of ovaries
were observed. Histological examination showed apparent differences between these two kinds of ovaries, whereas among male
shrimp, there were no such differences.
