Abstract
Abstract Aquatic animals can be kept alive over a long period of time by utilizing the apparatus of the present invention comprising: a water tank for containing aquatic animals and environmental water, which tank has an inside volume large enough to contain the aquatic animals in an amount greater than 200 kg per m 3 of the environmental water; a control path for containing a portion of the environmental water, which control path is located outside the water tank and is connected to the water tank through a windraw pipe and a return pipe line, while containing therein the following means: (1) means for controlling the temperature of the environmental water in the control path so that the temperature is maintained at a level as low as it is possible for the aquatic animals to exist, (2) means for bringing the environmental water in the control path into contact with air, (3) means for eliminating ammonia compounds from the environmental water, and (4) means for eliminating water-soluble organic compounds from the environmental water, and; a pump for recycling the environmental water through the water tank, the withdraw pipe line, the control path and the return pipe line.

Claim 1
Independent Claim
302 words
An apparatus for keeping aquatic animals alive over a long period of time comprising: (A) a water tank for containing aquatic animals and environmental water; (B) a control path for containing a portion of said environmental water, said control path being located outside said water tank; (C) a withdraw pipe line connected at an end thereof to a bottom portion of said water tank and also connected at the other end thereof to an inlet portion of said control path; (D) a return pipe line connected at an end thereof to said water tank and also connected at the other end thereof to an outlet portion of said control path; (E) means for controlling the temperature of said environmental water in said control path so that it is maintained at a level as low as it is possible for the aquatic animals to exist, said temperature control means being disposed in said control path; (F) means for bringing said environmental water in said control path into contact with air; (G) means for eliminating ammonia compounds from said environmental water, said eliminating means being located in said control path; (H) means for eliminating water-soluble organic compounds from said environmental water, said eliminating means being located in said control path; (I) a pump for recycling said environmental water through said water tank, said withdraw pipe line, said control path and said return pipe line; (J) a supply source of an oxidizing agent connected to said withdraw pipe line at a location upstream from said ammonia compounds eliminating means and said water-soluble organic compounds eliminating means; and (K) means for converting said oxidizing agent into a substance which is non-toxic to said aquatic animals, contained in said control path and located downstream from said ammonia compounds eliminating means and said water-soluble organic compounds eliminating means.
