Development of embryos, larvae, and juveniles of were observed using an optical microscope, with a digital camera at water temperatures of 28℃ to 29℃ and salinity of 24 to 25. Zygotes began the first cleavage at 50 min post-fertilization, developed to D-shaped larvae between 22 and 24 h, and the larvae developed eye points and feet at day 11 and entered the attachment metamorphosis stage. There was no significant difference in the time of embryo development between the selective and control lines (>0.05). The shell length and shell height were not significantly different at the embryonic and early larval stages between the selective and control lines (>0.05), but there was a significant difference in shell length and shell height at the post-larval and attachment metamorphosis stages between the selective and control lines (<0.05). The metamorphosis and survival rates of the selective line were significantly different from those of the control line (<0.05), and the selective line has obvious advantages. The results show that the growth of the early planktonic larval stage of was slow but at the post-larval and juvenile stages, it was rapid. The growth of shell length and shell height of was not synchronized. The growth speed of shell length exceeded that of shell height at the earlier larval stage, and at the later larval stage, the growth speed of shell height exceeded that of shell length; at 28 to 30 days, shell height exceeded shell length. At the larval and juvenile stages, the growth of the selective line significantly exceeded that of the control line. The selective line has obvious growth advantages and growth potential.
