The present invention provides a compact culture system to produce microalgae, live food animals and fish fry (new born fish) in a serial manner. The culture system is composed of three individual reactors of same size positioned in different levels on three shelves of a frame. In the top-level reactor, microalgae is grown symbiotically with fish. With so grown microalgae, live food animals in the middle-level reactor are fed. Finely, the live food animals are transferred into the bottom-level reactor to feed fry in it. Culture water in the system is self-cleaned by the metabolic activity of the photosynthetic microalgae, and is circulated through the reactors continuously or intermittently. Heaters, thermometers, aerators, illuminators, and water pumps are equipped in the system to offer optimal growth conditions for the organisms. Extra electric outlets are provided for the use of pH-meters, oxygen-meters, carbon dioxide-meters, ammonia-meters when needed to control the water quality.
A culture system for growing a plurality of different living organisms, the system comprising a first reactor growing microalgae positioned above a second reactor growing live food animals positioned above a third reactor raising fish fry, wherein the microalgae grown in the first reactor are supplied to the second reactor to feed the live food animals and the live food animals grown in the second reactor are supplied to the third reactor to feed the fish fry.
A method of growing microalgae, live food animals, and fish fry which have food-chain relationships to one another, the method comprising:
