Fish for future,
For the people,
For our planet



Today, we’re faced with various social problems – such as shortage of protein sources, and downturn in Japanese aquatic industry.
And we have very little time to solve these issues.

We believe a high-speed breeding can be a decent solution to these problems.
Our core technology “genome editing” can promote evolutionary changes on aquaproducts from DNA level in super-short time.
This can significantly fast forward the current breeding process.

Our mission is to bring Japanese aquaculture to the next level.
By installing our core technology along with digital technology such as AI/IoT, we aim to make aquaculture smart, attractive, and sustainable.
And we believe that such evolution of the industry itself will be a solution to the protein crisis of the world.

Protein Crisis

Recent studies show that protein demand will exceed supply by 2030 and will require double the supply by 2050. As a decent source of animal protein, aquaculture needs significant improvement in its productivity.

Protein Crisis – protein demand exceeds supply
Fish is a super-efficient protein source

Downturn in Japanese Aquatic Industry

Japan used to be the largest producer of aquaproducts in the world. However, the production and the number of workforce have decreased to 1/3 in 30 years. Revival of Japanese aquatic industry is strongly desired.

On the contrary, Japanese aquatic industry has been declining


Genome Editing
– from “the Unexpected” to “the Expected”

Genome editing is a core technology to realize high-speed breeding. The technology enables us to fast forward the current breeding process by promoting natural changes on DNA.

  • While the history of breeding in agriculture and livestock has been more than 10,000 years, the same for aquaproducts has been only 50 years.

  • Genome editing technique can fast forward the breeding process from 30 years to only 2-3 years.

  • Genome editing is designed to promote natural evolution, not to create artificial traits by introducing foreign genes like GMO.

Smart Aquaculture
– Creating a New Style of Aquaculture

Aside from the high-speed breeding, in order to make aquaculture a better industry to work in, we also aim to transform the land aquaculture into a productive and sustainable model.

  • Optimize the growth environment using AI/IoT. (temperature, salinity, dissolved oxygen, light, etc)

  • Establish environmentally friendly aquaculture system by using clean energy and waste recycling.

  • Monitor and control the growth environment 24hours/7days to save manpower.
