Medaka Fish Successfully Reproduce in Space During 1994 Experiment

Four medaka fish flew into space in 1994; 43 eggs were laid and eight baby fish hatched

Astronaut Chiaki Mukai took four medaka fish into space in July 1994 as part of an experiment to study reproduction in microgravity. The fish laid eggs during the mission, with eight of 43 identified eggs hatching in space. After returning to Earth, the adult fish gradually recovered, while the young “space medaka” continued to grow normally.
