The population continues to grow,
and consumption of marine products continues to increase.

Natural fish catches have already reached their peak,
and marine aquaculture is rapidly expanding around the world.
As a result, the environmental impact of fish droppings and leftover feed is becoming an
increasing problem.

To leave delicious fish and beautiful nature to the next generation.
What we need now is land-based aquaculture that does not depend on the sea.

We, FRD Japan, will create a future where freshly caught, safe and secure trout can be produced
anywhere in the world using a Closed RAS system.
