摘要
综述了鲟鱼类配子生物学的最新资料。间黄卵动物极具多个卵孔， 膜分４ 层， 最外层的胶质层含糖蛋白，其水合作用需 Ｃａ２ ＋ 、 Ｍｇ２ ＋ 离子和类胰蛋白酶。鞭毛型精子具顶体， 顶体反应形成受精丝。１７ － α， ２０ － β二羟朵烯黄体酮是促卵母细胞成熟的物质， 前列腺素和儿茶酚胺是促排卵物质。
The latest information on reproductive biology of sturgeon is summaried The mesolecithal eggs of sturgeon possess numerous micropyles at an animal pole The egg envelope consists of four morphologically distinct regions Hydration of the outermost adhesive jelly coat requires Ca 2+ ,Mg 2+ and trypsin like enzymes Sperm of sturgeon possess acrosomal process and acrosomal reaction includes the formation of fertilization filament 17α,20β dihydroxy 4 pregnen 3 one is maturation inducing substances Prostaglandin and epinphrine matures sturgeon oocytes
