Two groups of killifish, Fundulus heteroclitus, which were flown aboard Apollo-Soyuz, were subjected to postflight behavioral testing. The first group examined consisted of a graded series of embryos representing key developmental stages at orbital insertion (32-h, 66-h, and 128-h stages; pre-liftoff fertilization times). The tests revealed that the young adults from the flight 32-h stage had a significantly decreased positive geotaxis and increased negative phototaxis when compared with ground controls. These findings suggested a greater sensitization of the least-developed flight stage to post-hatching environmental influences. The second group consisted of 21-d old juveniles which were subjected to light orientation tests soon after recovery. No significant differences were detected.
两组花鳉（Fundulus heteroclitus）搭乘阿波罗-联盟号飞船飞行后，接受了飞行后行为测试。第一组接受检查的是一系列分级的胚胎，它们代表了轨道插入时的关键发育阶段（32小时、66小时和128小时阶段；发射前受精时间）。测试表明，与地面对照组相比，飞行32小时阶段的幼鱼正向地性显著降低，负向趋光性增加。这些发现表明，发育最不完善的飞行阶段对孵化后环境影响的敏感性更高。第二组由21日龄的幼鱼组成，恢复后不久就对它们进行了光定向测试。未检测到显著差异。
