Wish to Take Your Pet Fish for a Stroll? There’s a Bag for That!

A Japanese company is working on a whimsical, container-like bag for live fish, suitable for both pet owners who want to take their favorite fish on walks and fans of super fresh sashimi …

Known as the “katsugyo bag,” this portable aquarium is shaped like a long tube with a transparent center section, a handle and a meter that, if I had to guess, monitors the oxygen saturation of the water. It is being developed by the “Ma Corporation” and is intended to be a more elegant, efficient and environmentally friendly alternative to the old plastic bag filled with water.

The Katsugyo bag is currently still under development. So if you would like to spend something that you would like to spend money on, you will have to wait a little longer. The inventors are currently testing the device with a variety of edible fish and are documenting each experiment on Instagram.

Browsing through the photos and videos of the portable aquarium that have been uploaded to Instagram since October last year, the quirky product has moved on. In later versions the oxygen meter and the feeding connector (???) were added.

It is likely that the katsugyo pouch will be improved as it has been tested with more species of fish. For example, developers report that fish that swim a lot, like mackerel, may be more problematic to transport and they promise to make the necessary adjustments to their product.

Judging by the comments on most of the Instagram uploads, the Katsugyo bag could prove to be a commercial success not only in Japan but abroad as well. People are already asking about the cost of how to buy one and generally expressing their support for the project.

While the Katsugyo bag can very well be used as a portable tank for pet fish, according to the contents of the developers it is aimed at sashimi fans who want to make sure their favorite meal is as fresh as possible.
