More particularly, the present invention relates to a water tank device for freshwater eel culture, The present invention relates to a water tank apparatus for freshwater eel culture suitable for culturing up to the adult stage.

As is well known, ecological migration characteristics of representative freshwater eels of freshwater and marine migratory fishes suggest that the deep sea (estimated to be the western margin of the South Pacific Mariana Islands) After the first metamorphosis in the form of a Palus (Leptocephalus; ie, a freshwater eel or a fish), it travels westward along a bustling ocean current and then travels north along the Kuroshio Current to reach the coast. It becomes secondary to eel.

The sea eel is used to control the concentration of salt by osmotic process while staying at a station (for example, estuary) for a certain period of time for a freshwater runway, and when it is flooded by fresh water such as a river, a river or a reservoir, After passing through the wastewater station, it regulates the salinity of seawater and then goes back to the deep sea area of the Pacific Ocean.

Therefore, in consideration of the ecological characteristics of the sea eel which is transformed from freshwater eel fish (ie, Leptosepalus) in the seawater, Eels are preferred when the aquaculture system is equipped with conditions of sea water, nose and fresh water in the aquaculture process to grow from the stage to the adult stage.
