Abstract: Provided are a closed rearing method and a closed rearing apparatus which can decompose and remove ammonia contained in rearing water without supplying an excessive amount of ozone and can also suppress generation of toxic oxidants. In a closed rearing method for aquatic organisms and marine animals involving an ozone treatment for decomposing ammonia in rearing water by supplying a gas containing ozone into the rearing water, the closed rearing method is characterized in that aquaculture is performed in a closed environment by a first step for determining the ozone concentration of the gas and pH conditions of the rearing water suitable for reducing the amount of generation of toxic oxidants by previously treating the rearing water to reduce ammonia contained therein to the target value by using an apparatus for actually conducting the treatment and a second step for conducting an ozone treatment of the rearing water according to the suitable ozone concentration and pH conditions determined in the first step.

Abstract: A circulation type aquaculture method and a circulation type aquaculture apparatus which treat and remove ammonia harmful to fishes/shellfishes. The method includes a first step of finding an ammonia decomposition rate upon preliminarily treating cultivation water by using ozone or hypochloric acid so as to set a target remaining amount of ammonia after the decomposing treatment, a second step of finding the amount of ammonia in cultivation water so as to calculate a treating period of time required for reducing the amount of ammonia to the target remaining amount of ammonia based upon the ammonia decomposition rate of the first step, a third step of treating the cultivation water using ozone or hypochloric acid during the treating period of time calculated in the second step so as to treat and decompose ammonia in the cultivation water and a fourth step of returning the cultivation water to the aquaculture tank.
