Abstract
Tetraploids of Penaeus chinensis were induced by temperature shocks and chemical treatment with cytochlasin B(CB). A combination method of manipulation of light cycle and selection of the animal with pre–spawning behavior was used to get batches of fertilized at appropriate time. The tissues of midgut and/or antennal gland from juvenile, subadult, and the whole larvae were used for chromosome preparation. The results of ploidy detection showed that the most effective treatment with temperature produced 60% tetraploids, whereas the result with CB treatment was 66.7%. Thousands of animals indoor survived still in October with body length of 80-100 mm. The preliminary comparison of growth rate indicated that the tetraploid had statistically significant dominancy by about 20% than that of the diploid.
