海生双壳贝类Mytilopsis sallei是一种污染生物，已经入侵了其原始范围以外的栖息地。了解它的早期发展将有助于早期发现环境中的物种，识别压载水中的物种，并制定针对早期生命阶段的控制策略，这将有助于我们更好地管理这种重要的入侵者。本文首次用光学显微镜和扫描电子显微镜描述了沙雷氏沼虾的胚胎发生、贝壳形成和幼虫发育过程。释放的卵母细胞直径为毫米。受精卵在27+1.8℃下孵化。受精后(HPF)6.0+2.3h发育出顶端丛生原生孢子体。在16.5±4.2HPF时，出现D形绒毛，其壳长(SL，Mean+SD)为87.3±8.2 mm，每个都有一层膜和一层钙化的壳。受精后2~3d，D形绒毛发育为卵形幼虫(SL？111.9±10.7 mm)，最后一个专性自由丝状期。在6~8dpf观察到的小儿组(SL≈232.8±37.1 mm)既能用膜游泳，也能用脚爬行。小儿科通过分泌足底丝线定居下来，并变质为(SL？298.7±45.2 mm)8-10dpf。值得注意的是，这种入侵双壳类的幼虫能够在10d内安顿下来。这是首次详细研究德氏双壳螺科一种的早期贝壳形成。原肠胚期出现壳野内陷，在担轮孢子发育阶段，壳层物质以马鞍形向两侧伸展，分泌壳质。
The marine dreissenid bivalve Mytilopsis sallei is a fouling organism that has invaded habitats outside its original range. Understanding its early development will be useful for early detection in the environment, for species identification in ballast water and for development of control strategies targeted at early life stages, which will help us better manage this important invader. The processes of embryogenesis, shell formation and larval development of M. sallei are described here for the first time by using light and scanning electron microscopy. Released oocytes are 64 mm in diameter. Fertilized eggs were incubated at 27+ 1 8C. The trochophore, with an apical tuft and a prototroch, developed by 6.0+ 2.3 h postfertilization (hpf). At 16.5+ 4.2 hpf, D-shaped veligers with shell length (SL, mean+ SD) of 87.3+ 8.2 mm appeared, each possessing a velum and a calcified shell. At 2–3 d postfertilization (dpf ), the D-shaped veligers developed into umbonate larvae (SL ¼ 111.9+ 10.7 mm), the last obligate freeswimming veliger stage. Pediveligers (SL ¼ 232.8+ 37.1 mm) observed at 6–8 dpf could either swim using their velum or crawl with their foot. Pediveligers settled by secreting byssal threads and metamorphosed to plantigrades (SL ¼ 298.7+ 45.2 mm) 8–10 dpf. It is noteworthy that the larvae of this invasive bivalve are capable of settlement within 10 d. This is the first detailed study of early shell formation of a species of the family Dreissenidae. Shell field invagination appeared during gastrulation, secreting shell material by expanding over both sides in a saddle-shape during the trochophore stage.
