CULTIVATION APPARATUS OF LIVING ORGANISM TO CAUSE RETIDE AND ITS PREDATOR

An apparatus for cultivating protozoan predators preying red tide and green algae-causing microorganisms is provided to manufacture protozoan predators massively and with high purity. An apparatus for cultivating protozoan predators preying red tide and green algae-causing microorganisms includes a raw water tank(10), a filtering part(20), a plurality of first cultivation vessels(30), a plurality of second cultivation vessels(50), a discharge unit(80), and a constant temperature cultivation chamber(90). The raw water tank is supplied fresh water through a raw water supply route(1). A raw water supply pump(2) is installed in the supply route. The filtration part is installed on a connection pipe line(110) connecting the raw water tank, the first and the second cultivation vessels. The filtration part is installed on a diverging point(113) of a second connection pipe line(112). The second cultivation vessel is connected with the first cultivation vessel through a third cultivation vessel.
