对人工养殖条件下嘉庚蛸(Octopustankahkeei)的基础生物学和繁育技术进行了初步研究。嘉庚蛸喜栖息于阴暗的场所,属昼伏夜出型,主要捕食一些活体的天津厚蟹(Helicetientsinensis)等。其个体产卵量非常低,为60～1 1 0粒头,平均仅85粒 头。繁殖季节,雌雄个体间存在交配行为,交配后精子贮藏在雌性的纳精囊中。受精卵分2～3批产出,成葡萄状悬挂于瓦罐底部,亲蛸(♀)具有护卵行为。受精卵约经过40～45d孵化出膜,为盘状卵裂,经过肉眼可见的“红珠”期、“黑珠”期、胚胎的逆转,最后孵化出幼体。
A preliminary study of the basic biology and breeding techniques of Octopus kankiekei in captivity was conducted. Jiageng hi hi habitat in the dark place, is a nocturnal emission, mainly on the living predators of Tianjin Crab (Helicetientsinensis) and so on. Its individual fecundity is very low, 60 to 110 heads, with an average of only 85 heads. Breeding season, male and female individuals have mating behavior, post-mating sperm stored in female seminal vesicle. Fertilized eggs were divided into 2 to 3 batches of output, hanging in the bottom of the jar into grapes, pro-Qin (♀) with egg protection behavior. After 40 ~ 45 days, the fertilized eggs hatched out of the membrane for discoid cleavage. After the “red bead” period, the “black bead” period and the reversal of the embryo that were visible to the naked eye, the larvae finally hatched.
