Abstract

The tropical oyster Crassostreairedalei (Faustino 1932) was successfully cultured in west coastal area of Peninsular Malaysia. It was spawned in hatchery and the larvae were reared to setting. But there was no documented information regarding to the early development of C. iredalei larvae in Malaysia. Thus, this research will describe the embryology and larval development of tropical oyster in the hatchery. The size of unfertilized eggs averaged 44.71±1.80μm. First polar body was observed at 3 min after fertilization followed by second polar body and meiosis up to 20 min. Embryos developed into morula after 2-3 h and swimming blastula after 3-5 h. Trochophore larvae seen at 16-18 h. The larvae grew through veliger, umbo, eye-spot and pediveliger stages in the planktonic phase about 2 weeks before settling as plantigrade and metamorphosing to spat on a suitable substratum. Spatfall began on day 16 and continued until day 21. The linear relationship between shell length and shell height in larvae is given by y= 1.2217x – 7.374, R 2 = 0.939 and growth of the larvae is linear. This study will contributevaluable knowledge needed for aquaculture to optimize larval rearing conditions and spat production in hatchery.
