CULTURE SYSTEM OF SEAFOOD, CULTURE FACILITY OF SEAFOOD AND CULTURE METHOD OF SEAFOOD

摘要

To provide a culture system, a culture facility, and a culture method of seafood capable of significantly reducing initial cost of installation of facility equipment and running cost of an operation of the facility equipment, by using a semi-closed circulation type water tank which uses underground sea water for a heat source and water quality purification.SOLUTION: A culture system 1 comprises: a culture facility 2 in which, a heat insulation side groove 22 is provided in a circumferential direction on a floor face 212 and a closed space is formed; a water tank part 3 installed in the facility 2; and a supply hole 4 for withdrawing underground sea water from an underground constant temperature layer U and supplying the underground sea water to the water tank part 3. The culture system further comprises: a discharge part 32 for discharging some of culture water which overflows out of the underground sea water supplied to the water tank part 3 to the heat insulation side groove 22. The culture water discharged from the discharge part 32 flows as a straightening flow which is lifted up/down and agitated inside of the heat insulation side groove 22. At the time, heat from an external part is heat insulated by the straightening flow which is lifted up/down and agitated of the underground sea water in the heat insulation side groove 22, so that, a temperature of the culture facility 2 is kept to a temperature of the underground sea water always.SELECTED DRAWING: Figure 1
