An experiment was conducted to examine the effect of four different external biologger attachment methods: no attachment (control), anchor attachment (AA), monofilament attachment (MA), and silicon tube attachment (SA); at three different water temperatures (15, 20, and 25°C) on the oxygen consumption rate (OCR) of spotted sea bass (mean body weight 2,175.0 g). Fish OCRs were significantly affected by the blogger attachment method (P<0.001), water temperature (P<0.001), and their interaction (P<0.001). Fish OCRs increased significantly with increasing in water temperature, independent of the blogger attachment method. The OCRs of AA, MA, and SA were considerably higher than that of the control in 20°C. At 25°C, the OCR of AA was significantly higher than the other attachment methods, but there was no difference among the control, MA, and SA. The Q10 values of AA, MA, and SA were highest at water temperatures ranging from 15 to 20°C. The metabolic energy consumption rate (MEC) of fish increased with increasing water temperature in all experimental groups, and the MEC of AA was the highest at all water temperatures. These results indicated that SA is an appropriate biologger attachment method for spotted sea bass under our experimental condition.
