英文摘要	观察和记录了条纹斑竹鲨(CHIlOSCyllIuM PlAgIOSuM)在圈养条件下求偶、交配和产卵的过程,并就鲨鱼的交配和生殖行为进行了讨论.条纹斑竹鲨的求偶和交配过程可以分为游弋、雄性鳍脚弯曲、雌雄交配和雄性鳍脚抽离4部分.游弋在整个过程中占的时间最长,雌、雄鱼在确认交配信息后,雄鱼鳍脚发生弯曲;随后不久,进行交配;交配完毕后,雄鱼鳍脚便抽离雌鱼泄殖腔.条纹斑竹鲨产卵时,雌鱼腹部持续地磨擦或挤压水池中的水管和木桩等物体从而加快排卵的速度.卵鞘从体内排出后,雌鱼用口叼住卵鞘绕着水管、树桩和石头等来回游动,利用角丝将卵鞘牢牢地缠绕在这些产卵基质上.雌鱼产卵的时间并不固定,大多数发生在夜间,偶尔在白天也可以看到新产出的卵.产出的卵多数是成对的,偶尔只有1个.雌鱼产卵时间持续约60 d,每7--9 d产卵一次,在一个生殖季节内,每尾条纹斑竹鲨产卵约11个(圈养亲鱼的雌雄比例是2∶1).; The captive white-spotted bamboo sharks were kept to observe their courting,mating and spawning behavior,and their mating and reproductive behavior were discussed.The courtship and copulation process of the white-spotted bamboo shark can be divided into four parts:cruising,bend of male′s clasper,copulation and extract of male′s clasper.Cruising took most of the time of the whole process.After the mating information was confirmed between the male and the female,the clasper of the male began to bend and then they copulated.After the copulation,the clasper was extracted from the cloaca of the female.When the female ovulated,she rubbed her abdomen with pipes,stub in order to speed up the deposition process.After the egg case deposited out of the body,the female held it in the mouth circling around the pipes,stubs or stones,finally,the egg cases were entangled firmly with them by tendrils.The time of the female deposited was not fixed,which most happened at night and in the day occasionally.The female produced two eggs at most time,one occasionally.Deposition of eggs extended for 60 days or so and the eggs were produced every 7 to 9 days.One female produced 11 eggs on average in a single breeding season with the parent-fish sex ratio of keeping was 2∶1(♀∶♂).; 我国近海海洋综合调查与评价(908专项)(FJ908-02-01-08;FJ908-02-04-05);海洋公益性行业科研专项项目(200905019-6)
