        To determine the heart rate, body temperature, and behavior pattern of olive flounder (Paralichthys olivaceus) according to the change in water temperature. The breeding experiment was conducted by giving the water temperature change (Table. 3) for 7 days. After randomly taking out 6 olive flounder (Table 1) from the experimental tank, extracting each of the experimental fish, anesthesia for 3 minutes, and then incising 40mm behind the pectoral fin along the midventral line to make a biologger (DST). milli-HRT ACT, star-oddi, ICELAND) (Fig. 1) was inserted into each experimental fish. The experimental water temperature was gradually increased to 20°C for 3 days from 7.8°C, then lowered back to 18.2°C at the start and then increased to 19.4°C. As a result of the experiment, as the water temperature increased, the frequency of action decreased, but the radius of action increased and as the water temperature decreased, the frequency of action increased, but the radius of action decreased. In addition, as the water temperature increased, the body temperature increased, and the heart rate hardly changed when the water temperature increased but increased when the water temperature decreased.
