The current mainstream aquaculture method is sea surface aquaculture, in which fish are raised in high density in offshore ponds, but this method has become problematic due to its negative impact on the environment, such as the red tide caused by the deterioration of water quality caused by leftover food, excrement, and carcasses. In addition, high-density environments can lead to the development of fish diseases and require feed mixed with antibiotic medicine.

The aquaculture method that uses a filtration system to purify and circulate the rearing water was conceived to address these issues in sea surface aquaculture. Basically, the rearing water is not discarded and the fish can be kept in a stable environment, making it possible to cultivate them in a limited indoor space.

Unlike conventional aquaculture systems, this system is designed to be easy to install and energy efficient.

The simple system provides ease of installation, as well as low initial cost and low running cost.

The system is so simple that it can be used without any specialized knowledge.

It is safe and secure, free of disease and parasites, without the use of any chemicals.

As artificial seawater is circulated for aquaculture, there is no drainage into rivers or oceans. This is a sustainable aquaculture that is friendly to the natural environment.

In addition to being less susceptible to external factors such as rough weather, the water temperature can be adjusted throughout the year, shortening the cultivation period and achieving high productivity.
