At present, the Korean aquaculture industry is in a production rate for certain varieties, causing overproduction and price collapse annually, which is causing difficulties in farm management. In addition, with the increase of national income and the development of the food service industry, consumption of live fish is rapidly increasing due to the demand of domestic consumers who prefer live fresh seafood. Therefore, the production volume of live fish captured and cultured in the coastal waters can not keep up with the consumption, and it takes a lot of logistical costs to transport live fishes from the mountain area to the consuming area. Therefore, Has risen sharply.

In order to transport live fish to consumers from the mountain area to the consuming area under normal temperature conditions, the ratio of live fish to the number of live fishes is 15%: 85%. However, the live fish survival time Can not be maintained for more than 24 hours. Therefore, most of them are limited to short-distance transportation. In case of long-distance transportation, they depend on small-sized transportation using airplane. The price increase is even greater.

Due to the above factors, it is possible to transport a large amount of live fishes by long distance by using containers of vessels and to minimize the logistics cost, and furthermore, In addition to importing and exporting competitive domestic live fish, efforts are also being made to transport live fish such as young fish and ornamental fish safely over long distances and for a long time.
