摘　　要：为了满足真蛸浮游幼体阶段的营养需要,研究了几种饵料生物对真蛸浮游幼体的育苗效果。结果表明:轮虫不宜作为真蛸浮游幼体的生物饵料;恒温培养试验得出混合营养强化的丰年虫幼体的育苗效果优于混合营养强化的蒙古裸腹溞,并优于小球藻强化的丰年虫幼体及蒙古裸腹溞;常温试验得出梭子蟹溞状幼体+丰年虫幼体组合的饵料效果最好,而微囊营养强化剂强化的丰年虫幼体的育苗效果好于混合营养组合。综上所述,可认为:梭子蟹溞状幼体+丰年虫幼体组合是真蛸浮游幼体期比较适宜的饵料。Growth and survival rates of Octopus vulgaris paralarvae feeding on rotifers, enriched anaemia nauplii, enriched Moina mongolica, Daphnia - like larvae of Ponaunus trituberculatus were tested. The result showed that rotifer was not appropriate for Octopus vulgaris paralarvae as diet; the effect sequence of diets on growth and survival rates of octopus vulgaris paralarvae in constant temperature test was mix enriched anaemia nauplii 〉 mix enriched Moina mongolica 〉 anaemia nauplii enriched by Chlorella 〉 Moina mongolica enriched by Chlorella; the effect sequence of diets on growth and survival rates of octopus vulgaris paralarvae at room temperature test was daphnia - like larvae of Ponaunus trituberculatu ＋ anaemia nauplii 〉 anaemia nauplii enriched by fish oil 〉 mix enriched anaemia nauplii. It may be considered that the ＂daphnia - like larvae of Portunus trituberculatu ＋ anaemia nauplii＂ was the better food for the paralarvae of Octopus vulgaris.
