In the new journey of space exploration, China's space industry has once again taken an innovative step. The astronauts of the Shenzhou-18 manned spacecraft will carry out the first in-orbit aquatic ecology research project in China - space fish farming.

The astronauts of Shenzhou-18 will conduct an unprecedented experiment in space: raising fish in a space environment. This initiative not only demonstrates the tremendous progress of human science and technology, but also reveals to us the many differences between life in space and life on Earth.
1. Background and purpose of the experiment:
This space fish farming experiment is the first in-orbit aquatic ecology research project in China.
The research targets zebrafish and goldfish algae are aimed at establishing a stable and functioning spatial self-circulating aquatic ecosystem.
The experiment is not only an in-depth study of fish biology, but also an exploration of the future living environment of human beings in space.
2. Experimental environment and conditions:
The astronauts crafted a small aquarium for the fish, with special materials and designs to withstand the extreme environments of space.
Fish need to be provided with food and water on a regular basis, and their health and growth need to be monitored.
All operations need to be performed in a weightless environment, which adds to the complexity and challenge of the experiment.
3. Selection of research subjects:
Zebrafish were selected as one of the research subjects because they have up to 87% genetic homology with humans, which can reliably simulate and predict human physiological and pathological processes.
Zebrafish also have the ability to hibernate, which may help reduce the potential threat to human health from the radiation environment of space.
4. Significance and value of the experiment:
This experiment will help us understand the survival status of fish in space, and provide a useful reference for future space agriculture and ecosystem construction.
At the same time, by studying the physiological response and adaptability of zebrafish in space, it can provide important biological data for human space habitation and long-term space flight.
To sum up, it is an epoch-making scientific experiment that the Shen-18 astronauts will raise fish in space, which not only expands our understanding of space biology, but also provides new ideas and directions for future space exploration and human habitation.
According to the China Manned Space Engineering Office, the Shenzhou-18 astronaut crew will carry zebrafish and goldfish algae into space, aiming to establish a stable operation of the space self-circulating aquatic ecosystem. This initiative not only marks a new breakthrough in China's space life science research, but also lays the foundation for future research on space agriculture and biological regeneration life support systems.
Zebrafish, because of its high genetic homology to humans, were ideal for this experiment. As an aquatic plant, goldfish algae will play an important role in the ecosystem, providing oxygen to the system through photosynthesis. In the space environment, the symbiotic relationship between the two will be carefully observed and studied, in order to provide a reference for the ecological design of the future space living environment.
This space fish farming experiment is not only an in-depth exploration of life science in the space environment, but also another brave attempt to live in space. The Shenzhou-18 astronauts will shoulder this historic scientific research mission and show the world the vigorous development and infinite possibilities of China's space industry.
Fish farming in space, an unprecedented scientific research project, will undoubtedly stimulate global attention and enthusiasm for space life sciences. We look forward to the successful practice of the Shenzhou-18 astronauts and writing a new chapter in the space exploration of China and the world.
People haven't been to space yet, but this time the fish went up first, and it is estimated that the fish never thought that they would go to space in their lives!
