The giant Pacific octopus (Enteroctopus dofleini) is a popular exhibit species in public display aquaria, but information on health and disease is limited. This retrospective review evaluates time in collection and describes antemortem clinical signs and pathology of giant Pacific octopuses in an aquarium setting. Between March 2004 and December 2013, there were 19 mortalities: eight males, 10 females, and one individual whose sex was not recorded. Average time spent in collection for all octopuses was 375 ± 173 days (males 351 ± 148 days, females 410 ± 196 days). Ten (52.6%) of the octopuses were sexually mature at the time of death, six (31.6%) were not sexually mature, and reproductive status could not be determined in three octopuses (15.8%). Minimal changes were noted on gross necropsy but branchitis was histologically evident in 14 octopuses, often in conjunction with amoeboid or flagellate parasites. Senescence, parasitism, and husbandry were all important contributors to mortality and should be considered when caring for captive octopuses.
巨型太平洋章鱼（Enteroctopus dofleini）是公共展示水族箱中受欢迎的展览物种，但关于其健康和疾病的信息有限。本回顾性研究评估了采集时间，并描述了水族箱环境中巨型太平洋章鱼的生前临床症状和病理学特征。2004年3月至2013年12月期间，共有19只章鱼死亡：8只为雄性，10只为雌性，1只性别未记录。所有章鱼的平均采集时间为375±173天（雄性351±148天，雌性410±196天）。其中10只（52.6%）章鱼在死亡时已性成熟，6只（31.6%）未性成熟，3只（15.8%）章鱼的生殖状态无法确定。大体尸检时发现变化极小，但组织学检查发现14只章鱼有鳃炎，常伴有变形虫或鞭毛虫寄生虫。衰老、寄生虫感染和饲养管理都是导致死亡的重要因素，在照料圈养章鱼时应予以考虑。
