Storyline


The four zebrafish brought into orbit by the Shenzhou-18 spaceship on April 26 are now in good conditions after staying 20 days in China’s space station, according to researchers.

The four fish are now living in a small "aquarium" in the Wentian laboratory module on the Tiangong space station.

They were sent to the space station for a life science and ecological experiment, which requires the three Shenzhou-18 astronauts, Ye Guangfu, Li Cong and Li Guangsu, to create a simplified version of an aquatic ecosystem using zebrafish and hornwort to study how the space environment affects their growth and system balance.

So far, the astronauts have successfully carried out two times of water sampling and one fish food container replacement. They have found some abnormal directional behaviors of the zebrafish in microgravity, such as making rotational movements, going in circles and even swimming upside-down.

The water samples, fish eggs, and videos recording spatial movement behaviors of the zebrafish will be sent back to Earth for scientists to study the influence of space environment on the growth and behaviors of vertebrates, which will provide reference for researches on material circulation of contained ecosystems in space.

If the experiment succeeds, it will be a significant breakthrough to cultivate vertebrates in China's space program. Not only will the astronauts find joy in the space "aquarium," but it may also pave the way for their future counterparts to enjoy nutritious fish from their own in-orbit harvests.
