| 摘 要： | 为了提高文蛤等经济贝类的稚贝成活率,对文蛤等7种经济贝类的生殖腺中脂肪及脂肪酸的含量进行了研究。试验结果表明:不同的贝类总脂肪含量不同,其中,缢蛏最高,可达25.48%,虾夷扇贝22.32%,文蛤21.27%,泥蚶19.89%,紫贻贝16.79%,杂色鲍15.75%,青蛤含量最低,只有14.88%。由于浙江沿海的缢蛏一般是在10~11月产卵、受精及完成胚胎发育,在这种低温条件下配子的成熟和受精卵发育需要大量的能量,缢蛏的脂肪含量为最高,精巢为11.02%(占所取样品干重),卵巢为14.46%。雌雄生殖腺的脂肪含量也不同,一般是雌性生殖腺脂肪含量明显高于雄性生殖腺。不饱和脂肪酸的含量大于饱和脂肪酸,其中,紫贻贝含量最高,为67.23%,文蛤次之67.19%,泥蚶第三64.27%,虾夷扇贝59.74%,缢蛏59.40%,青蛤最低,仅为57.51%。生殖腺的质量是繁殖成败的关键,其中脂质的积累是影响生殖腺发育的主要因素之一。

| Abstract: | Fat and fatty acid levels were determined in gonads in 7 economic shellfishes to illustrate the gonadal development. The contents of the fat was 25.48%, 22.32%, 21.27%, 19.89%, 15.75%, 16.79%, and 14.88% in Sinonovacula constricta, Patinopecten yesoensis, Meretrix meretrix, Tegillarca granosa, Mytilus edulis, Haliotis diversicolor and Cyclina sinensis, respecitively. There were higher fat and fatty acid contents in the female gonads than in the male ones. The contents of unsaturated fatty acids were higher than the saturated fatty acids. The content of the unsaturated fatty acids was 67.23%, 67.19%, 64.27% , 59.74%, 59.40%, and57.51% in Mytilus edulis, Meretrix meretrix, Tegillarca granosa, Patinopecten yesoensis, Sinonovacula constricta, and Cyclina sinensis, respectively. |
