Fish Farming on Moon? Scientists plan to feed astronauts seafood farmed on the Moon

Water from polar lunar ice would fill their tanks. The fish would live in a closed-loop tank system. Waste from fish would feed algae and other species. Shrimp and worms would eat the rest of the waste. These species would also become fish food.

This sustainable method mimics aquaculture systems used on Earth. The goal is zero waste and full self-sufficiency in space. Scientists hope to feed a seven-member crew twice weekly. That would need 200 fish for a 16-week mission.

Testing sea bass survival in space conditions
The idea of animals in space is not new. But this is the first attempt to farm fish on the Moon.

Missions from the 1970s carried guppies and mummichogs. Zebrafish have also visited the International Space Station. But these were only for scientific study.

Now, Lunar Hatch hopes to farm fish for real use. Scientists tested if eggs can survive launch stress. Using simulators, they mimicked rocket vibrations and conditions. Tests show eggs stayed strong and developed normally.

Radiation, weightlessness and shaking did not damage them. These results give researchers hope for a future Moon mission.

ESA support and future mission plans
Przybyla proposed the idea back in 2016 to ESA. He wanted it to be part of a future Moon base. Funding came in 2018 from France’s CNES space agency.

Lunar Hatch is now among 100 shortlisted Moon projects. ESA may use its Argonaut landers starting in 2034. These landers can carry over a tonne of equipment. Among their cargo may be sea bass eggs.

This effort may inspire new life-support systems for space. It may even help solve food problems back on Earth. In remote areas or conflict zones, closed food systems could help.

For now, sea bass near Palavas-les-Flots swim calmly. They may never reach space, but their young might. And that could help humans survive far beyond Earth.
