Triploidy induction with heat shocks toPenaeus chinensis and their effects on gonad development

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, t...

Summary: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.[PUBLICATION ABSTRACT]
