摘要
The present invention relates to a donut-shaped display fish tank for tunas having a recirculation system which: promotes an optimal environment for the tunas to live for a long time; grows the tunas without diseases; displays the tunas for a long time; resolves an inconvenience of frequently changing sea water in the fish tank; and lessens a financial burden of frequent sea water change, by allowing the tunas to freely move and circulate with the optimum conditions. The donut-shaped display fish tank for tunas having the recirculation system comprises: a main body (12) which is formed in a donut shape and in which a space part (11) wherein sea water (SW) and tunas (F) are accommodated is formed; a fish tank (10) having multiple inlet/outlet ports (13) in the upper part of the main body (12); a circulation line (20) connected to an outlet (21), which is formed in one side of the lower part of the main body (12) so as to discharge the sea water, and an inlet (22), which is formed in the other side of the lower part of the main body (12) so as to introduce the sea water; a pump (30) installed in the circulation line (20) so as to circulate the sea water in the circulation line (20); and a filter (40) which is installed in the circulation line (20) and which filters out impurities in the sea water (SW) discharged through the outlet (21) by the pump (30) and supplies the filtered sea water into the main body (12) through the inlet (22).
