CIRCULATION TYPE CULTURE APPARATUS AND CULTURE METHOD FOR FISHES OR SHELLFISHES

PROBLEM TO BE SOLVED: To provide a circulation type culture apparatus for fishes or shellfishes and a culture method using the same, by which the installation can be simplified to more largely lower the cost of the installation than those by conventional techniques, and the labor and cost for the operation maintenance of the installation can also largely reduced. SOLUTION: The circulation type culture apparatus configured to include a filtration device 3 for separating off floated suspension substances in a rearing water tank 1 and a membrane separation activated sludge treatment device 2, wherein the circulation route has a first route for introducing sedimentary suspension substances in the rearing water tank 1 as first concentrated water into the membrane separation activated sludge treatment device 2, a second route for taking out a supernatant from the rearing water tank 1 and introducing the supernatant into the filtration device 3, a third route for returning the filtered water filtered with the filtration device 3 to the rearing water tank 1 together with treated water treated with the membrane separation activated sludge treatment device 2, and a fourth route for introducing the sedimentary suspension substances separated with the filtration device 3 as second concentrated water into the membrane separation activated sludge treatment device 2.
