In order to prepare groups of experimental fish for a further study on swimming power measurement,a 60 days culture using Tilapia mossambica was designed.The apparatus was composed of tanks, syphons, filters, and a submersible pump; and eachof them were carefully arranged to form a circulating system.Prior to the fish culture, a preliminary test without fish and aeration was executed; and aconclusion was obtained that there was no O_2 dissolution into the system.The culturing test was carried out keeping a group of 25 Tilapia in each 200 1 tank, and D.O.values for each tank were recorded at 5:00 in every afternoon.In this experimental culture, D.O. values for each tank were significantly ordered. According to the conclusion from the preliminary test,the differences in D.O. value between eachtank were considered to be caused by their own respiratory consumption. Therefore, O_2consumption for each group was calculated as follows： ― Group B: 168.3ml/kg/hr at D.O. condition of 2.0ml/lGroup C: 142.3ml/kg/hr at D.O. condition of 1.2ml/lGroup D: 108.1ml/kg/hr at D.O. condition of 0.6ml/lO_2 consumption for Group A may be calculated by setting a reservior between aeratingtank and tank A.
