The twelve hybrid families were obtained by broodstock of different shell shapes including “wide”, “middle”, “flat” in October, 2007. The experiment consisted of three hybrid categories (PH=0, HM, MP), and each category was made up of four hybrid families, which included twelve hybrid families altogether. The results showed that the morphology of parents was of significant difference, and the size of D larvae, size at settlement and metamorphosis, and the size of single siphon juveniles were not significantly different. At planktonic stage, the growth and survival of the larvae were different. The size of PH larvae was significantly bigger than HM and MP categories (P＜0.05，n=120）, and the growth rates were (10.21 ± 0.42), (9.96 ± 0.52), (9.29 ± 0.52) μm/d for these categories, respectively. The survival of 9d larvae of the PH category was significantly higher than the HM and MP categories. At the metamorphic stage, the larvae grew slowly. Larvae of the PH, HM and MP categories showed growth rates of (1.72 ± 0.48), (1.93 ± 0.53), (2.08 ± 0.39) μm /d, respectively, which were significantly different. The metamorphosis rates of these categories were (83.20 ± 8.47)%, (6.45 ± 3.06)%and (10.75 ±3.70)%, and the difference was extremely significant. At the nursery stage, juveniles of the PH, HM, MP categories showed significant difference in size and their growth rates were (16.74±3.06), (13.08 ± 2.24) and (15.20 ±2.55) μm/d, respectively. Survival of juveniles was also significantly different between each category, which was (93.25 ± 2.99)%, (90.75 ± 2.22)%and (87.25 ± 4.86)% for PH, HM and MP.
