EXPERIMENT INFORMATION

Killifish Development in Zero-G on Cosmos 782 (COS 782-17)
Principal Investigator
Research Area:
Developmental biology
Species Studied
Scientific Name: Fundulus heteroclitus Species: Fish, Killi

Description
Objectives:

The Fundulus embryogenesis experiment was the third in a series of experiments to assess the possible effects of the space environment upon developing organisms. On the Skylab-3 and Apollo-Soyuz missions, juvenile fish initially exhibited obvious disorientation reactions (swimming rapidly in loops and circles), but over a period of several days in orbit, they gradually adapted to weightlessness and to dependence on visual cues, while space-hatched fry exhibited no disorientation. The major refinement in this experiment is the use of a 1 g control centrifuge.
