摘  要：
本文以熊本牡蛎为材料,在高温季节,通过强化亲贝营养和26℃以上高温促熟培育,使熊本牡蛎亲贝快速成熟,利用阴干流水刺激方法诱导产卵,并进行了不同盐度下受精卵孵化实验;通过合理控制幼虫密度、投喂新鲜无污染的单胞藻、及时分级筛选等系列技术措施,克服了熊本牡蛎育苗成功率低的技术难题;开展了栉孔扇贝壳、长牡蛎壳和栉江珧壳三种附着基的采苗试验,结果显示牡蛎壳是理想的附着基,可使稚贝的附着变态率达到60%以上,促进稚贝的生长和成活,提高稚贝产量,壳长2mm以上的稚贝单位水体出苗量超过10×10~4粒/m~3。

摘  要：
UsedKumamoto oysters as materials,promoting the maturity of parents by enhancing nutrition and culturing in situations with higher temperature.Stimulated the female to spawn by drying them in the shade and putting them under flowing water.And the hatching rates of the fertilized eggs under different salinity conditions were studied.The results indicate that there are several methods to improve the low seedling successful rate of Kumamoto oysters:controlling the larvae densityreasonably(6~8个/ml in the early stage while 3~4/ml in the late stage),feeding unicellular algaewhich is fresh and pollution-free,changing water and inflating air scientifically and classifying and filtrating them in time.The adhering effectiveness of three adhering substances,chlamys farreri shell,oyster shell and Comb Pen Shell,were studied.The results indicate that oyster shell has the best effect.It can improve the Adhesion rate to over 60%,which improve the survive and growth of the juvenile oysters.Meanwhile,the output of juvenile oysters with size over 2mm is over 10 104/m3.
