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。
In this paper, the oyster of Kumamoto was used as the material, and the progeny of Kumamon oyster was quickly matured by intensive pro-nutrition and intensive cultivation at 26 ℃ in high temperature season. Eggs hatch experiment; through the reasonable control of larval density, fed fresh non-polluting monocytogenes, timely grading and other series of technical measures to overcome Kumamoto Oyster seedling success rate of low technical problems; carried out Zhikong scallop shell, oyster shell The results showed that the oyster shell was the ideal attachment base, which could increase the attachment rate of juvenile shellfish to over 60%, promote the growth and survival of juvenile shellfish, increase the yield of juvenile shellfish, Juvenile shellfish body length 2mm above the emergence of more than 10 × 10 ~ 4 / m ~ 3.
