ABSTRACT:
Aquatic animals can be kept in a living condition over a long period of time, without feeding them, by placing the aquatic animals, at a large density of more than 200 kg/m.sup.3 in environmental water; maintaining the temperature of the environmental water in a lowest possible range in which it is possible for the aquatic animals to exist; controlling the concentrations of ammonia compounds, water-soluble organic compounds and carbonic acid radical in the environmental water so that their levels do not exceed 20 ppm, 150 ppm and 1,000 ppm, respectively; and regulating the concentration of molecular oxygen dissolved in the environmental water so that it is 3 ppm or more.
