The oxygen consumption of Nothobranchius korthausae eggs in different developmental stages, including diapause II and III, was measured. Oxygen consumption increases exponentially during embryonic development. In diapause II and III there is a drop in oxygen consumption, which attains a minimal level in diapause II after 3 weeks and in diapause III after 2 weeks. During early development the embryos can escape from hypoxic stress by entering diapause I and II. During late embryogenesis embryos in diapause III can escape from hypoxic stress by hatching. We conclude that survival of annual fish embryos is enhanced during conditions of low oxygen concentration by reduced oxygen consumption rates during diapause.
对包括滞育II期和III期在内的不同发育阶段的科氏假鳃鳉卵的耗氧量进行了测量。在胚胎发育过程中，耗氧量呈指数增长。在滞育II期和III期，耗氧量会下降，在滞育II期3周后和滞育III期2周后达到最低水平。在早期发育过程中，胚胎可以通过进入滞育I期和II期来逃避缺氧应激。在胚胎发育后期，滞育III期的胚胎可以通过孵化来逃避缺氧应激。我们得出结论，在低氧浓度条件下，通过滞育期间降低的耗氧率，一年生鱼类胚胎的存活率得以提高。
