在屏東縣分佈的一種貝類(Psammotaea sp.)在當地又稱為海瓜子、赤嘴仔，是屬於高價格的貝類，其產量也日趨減少，為開發新的養殖對象並建立該種的繁養殖技術，擬對其生殖季節與繁殖的技術做初步的探討。本試驗擬測定其殼長與殼重、肥滿度，並對其生殖腺做組織切片觀察，以瞭解生殖腺發育，並探討其間之關係。另外探討種貝以何種方法刺激其排卵排精最為有效，同時以不同溫度觀察其胚胎發育，與進行鹽度對幼生成長與活存之試驗，以建立繁殖之初步資料。

Due to the decrease of natural resource and the high price in market of Psammotaeasp., it is neccessary to approach its reproductive season and the techniques of artificialpropagation. In the study of reproductive season of Psammotaea sp., the conditionfactor, shell length, total weight will be measured monthly. The gonad will be observedhistologically monthly to ubderstand the reproductive cycle. In the study of artificialpropagation of Psammotaea sp., the stimulating methods of spawning will be touched.The development of embyros and larvae in different temperature will be compared.Also, the effect of acute salinity on the larvae will be conducted.
