This research is carried out to design and construct mini flume tank that is reliable and ideal used for fish swimming behavior experiment through a series testing the flume tank for its technical performance. The mini flume tank has a maximum water velocity 85 cm/s (1.7 knots), with dimensions of 250 x 135 x 55 cm, and water capacity 155 litres. Based on the operation test, field observation on the tanks was clearly visible due to minimal air bubbles in the water flow. The observations for fish swimming behaviour experiment could be conducted from the two view fields (top and side) that allow observation of swimming endurance and fish tail flick easily. The water velocity visually was in laminar category at each level of the tested flow speeds. The rpm of motor was relatively stable for more than 200 minutes. The motor temperature was below 60 oC at frequency of 10 to 40 Hz. At frequency of 50 Hz the temperature reached 60 °C in 25 minutes and stable at 73oC after an hour. Water temperature changes during the test for more than 200 minutes at different speeds which have differences of 0.2 to 1.8 oC. The test result showed that the mini flume tank performance was reliable and ideal used for fish swimming behavior experiment.
