柔鱼科是头足类中最重要的经济渔业类群。然而，人们对它们的胚胎发育知之甚少。本文提供了详细的胚胎发育观察的三种ommastrephis bartramii，Sthenoteuthis oualaniensis和Eucleoteuthis luminosa。所有胚胎都是通过2013年12月在夏威夷群岛周围巡航期间在研究船Kaiyo Maru上进行的人工受精获得的。本文对巴氏奥氏藻的胚胎期和幼体期作了较详细的说明。孵化阶段进行了比较，所有三个物种之间，以及从文献中的信息onIllex argentinushatchlings。分析了输卵管腺粉对绒膜扩张的种属特异性影响。结果表明，尽管绒毛膜扩张的诱导物在物种间是相同的，但输卵管腺的总体化学性质是物种特异性的。此外，输卵管腺胶的治疗诱导部分孤雌生殖的早期阶段的胚胎发育，通过扩大卵周空间和胚盘的形成。
Ommastrephidae are the most important commercial fishery group among cephalopods. However, little is known about their embryonic development. This article provides details of embryonic development observed in three ommastrephids:Ommastrephes bartramii, Sthenoteuthis oualaniensis, andEucleoteuthis luminosa. All embryos were obtained through artificial fertilization conducted onboard the research vesselKaiyo Maruduring a cruise around the Hawaiian Islands in December 2013. The embryonic and paralarval stages ofO.bartramiiare explained in detail. The hatchling stages were compared between all three species, as well as with information onIllex argentinushatchlings from the literature. The species-specific effects of the oviducal gland powder on chorion expansion were analyzed. The results indicated that the overall chemical nature of the oviducal gland was species specific, although the inducer of chorion expansion was the same across species. In addition, treatment with oviducal gland jelly induced partial parthenogenesis in the early stages of embryonic development through the expansion of the perivitelline space and blastodisc formation.
