项目摘要
The frilled shark, C. anguineus is the most famous deep-sea elasmobranch fish which is though as a devonian relict species and to be distributed in the deeoseas almost all the world. However, little or nothing is hitherto known on the life history on this shark of great interest. From January 1984 to December 1988, 242 specimens (116 females and 126 males) were collected by midwater trawl net and bottom gill-net which were towed or set at depths between 60 and 450m. Their total lengths and body weights ranged 125.6-181.0cm and 3670-17370g in females, and 117.8-155.9cm and 2780-6360g in males. Twenty adult sharks were reared for 7 days or shorter in an aquarium. Stomach contents in 139 specimens (77 females and 62 males) were squids (23 samples, 16.5%), fishes (4 samples, 2.9%), and undetermined sediments (1 sample, 0.7%). Sexual minaimal sizes were surmised to be at about 110cm in males and about 140-150cm in females and to have no limited reproductive season in the present C. anguineus. Ovulation occurred at a stage of 80-90mm in diameter of the ovarian eggs. Fertilization occurred at the capsulogenous gland and fertilzed eggs were developed in the capsule in the uterus in their early stages. Those embryos, on andafter reaching 80mm in total length, came out of the capsule and continued to develop in the uterus. Pups were born at about 550mm in total length. Four fertilized eggs with developing emmbyos in the capsule were reared for 134 days in natural sea-water in an small aquarium tank.
皱鳃鲨C.鳗属(anguineus)是最著名的深海板鳃类鱼类,它被认为是泥盆纪的孑遗种,几乎分布于世界各地的深海。然而,迄今为止,对这种鲨鱼的生活史知之甚少。1984年1月至1988年12月,在60 ~ 450 m水深范围内,用中层拖网和底层刺网共采集到242头(雌116头,雄126头)。体长和体重雌性为125.6-181.0cm,雄性为117.8-155.9cm,雌性为3670- 17370 g,雄性为2780- 6360 g。20条成年鲨鱼在水族馆中饲养7天或更短时间。139个样品(77个雌性和62个雄性)的胃内容物为鱿鱼(23个样品,16.5%)、鱼类(4个样品,2.9%)和未确定的沉积物(1个样品,0.7%)。推测在本世纪,雄性的性生殖最小径约为110 cm,雌性的性生殖最小径约为140- 150 cm,生殖季节不受限制。真恶心排卵期卵径为80- 90 mm。受精发生在产囊腺,受精卵早期在子宫内的囊内发育。这些胚胎在总长达到80毫米后,从被膜中出来,并在子宫内继续发育。幼仔出生时全长约550毫米。在小型水族箱中的天然海水中饲养了4枚受精卵,在胶囊中发育了胚胎,为期134天。
