The marine bivalve mollusk is mainly distributed in tropical and subtropical waters of the southwestern Pacific Ocean, including coastal areas of China, Japan, Philippines, India, Indonesia, Australia and New Zealand. The species is relatively new to shellfish mariculture, having potentially high economic value and good prospects for development. This study used biological productivity methods to investigate the species' reproductive cycle, gonad development, fatness, breeding season, embryo development and larval development in the period from August 2013 to July 2014. In the examination of its breeding cycle, the gonadogenesis of presented a unimodal gametogenic cycle, with one spawning season annually. The gonad development of the species could be divided into five stages: proliferating stage, growing stage, maturing stage, spawning stage and resting stage. This shellfish's mode of reproduction is oviparity, with a slightly greater gonad development among males than female. The species displays gonochorism, with a female to male ratio of 1:1. The spawning season was recorded as from October to March. Peaks in spawning occurred in March, October and November, at water temperatures of 20.3-24.6℃. Fatness peaked at 33.43% in August, and the lowest measure of fatness was in April at ~18.31%. The cultivation of embryos and larvae revealed demersal, elliptically shaped eggs, and the egg diameter ranged from 70 to 80 μm. Under the conditions of water temperatures of 24-26℃ and salinities of 28-32, the fertilized eggs developed into D-shaped larvae, 90-110 μm in length, within 16 hours of hatching. After 7-8 days, the D-shaped larvae then developed into late-umbo larvae, 210-230 μm in length. Thereafter, the late-umbo larvae developed into juvenile mollusks within 4-5 days. These observations provide a foundation for the artificial breeding and protection of genetic resources of .
