| 摘 要： | 对人工养殖条件下长蛸Octopus variabilis的繁殖行为和胚胎发育进行了初步观察。结果表明：长蛸营底栖生活,以活体的蟹、贝、虾类等为主食,夜间或傍晚摄食活动加强;繁殖季节,雌、雄个体间存在交配行为,临产时雌体较为平静,产卵后一般不进食,卵子分批成熟,分批产出,受精卵较为分散地悬挂于池壁或附着基上,雌体具有护卵行为;人工养殖条件下亲蛸不能全部产出其所怀的卵,产卵量为25~54粒,单位体质量产卵量为0.8~1.3粒/g,亲蛸产卵时的最小体质量为36.2 g;受精卵行盘状卵裂,直接发生,胚胎发育经过卵裂期、囊胚期、原肠期、器官芽形成期、红珠期、黑珠期和胚胎的逆转,在水温为19~25℃、盐度为32~34时,胚胎经过66 d孵化出膜。

| Abstract: | The reproductive action and embryonic development of cultured octopus Octopus variabilis were observed.It was found that the octopus as a benthic animal fed primarily on living animals such as crab,shellfish,and shrimp more actively at night and at dusk.Females mated with males in the reproductive season and became calm before spawned.After spawned,generally the females did not feed,and the matured eggs were released in batches and were suspended on the pool wall separately or attached to the attachments.Th... |
