The high mortalities registered in the larval stage during octopus culturing are mainly due to nutritional deficiencies of the food provided. To understand the cause of this problem, we studied the ontogenetic development of the digestive system of Octopus bimaculatus paralarvae. An egg batch was obtained from a gravid female collected in the Bay of Los Angeles, Baja California, Mexico, and it was incubated in the laboratory during the summer of 2011. We observed that the formation of the digestive system began at 33 days post-laying (DPL). The newly hatched paralarvae had already formed the organs involved in food ingestion and digestion, although it was not possible to know accurately their degree of maturity. The present research constitutes the first description at the histological level of the ontogenic development of the digestive system of the O. bimaculatus paralarvae. This serves as a basis for future studies of the digestive physiology of this species.
章鱼养殖过程中幼体阶段出现的高死亡率主要是由于所提供食物的营养不足。为了解决这个问题的原因，我们研究了双斑章鱼仔鱼消化系统的个体发育。从墨西哥下加利福尼亚州洛杉矶湾捕获的一只怀孕雌章鱼获得了一批卵，并于2011年夏天在实验室中进行孵化。我们观察到消化系统的形成始于产卵后33天（DPL）。新孵化的仔鱼已经形成了参与食物摄取和消化的器官，尽管无法准确了解它们的成熟程度。本研究首次在组织学水平上描述了双斑章鱼仔鱼消化系统的个体发育。这为该物种未来的消化生理学研究奠定了基础。
