Abstract In order to understand the changes in oxygen consumption and activity of juvenile filefish Thamnaconus septentrionalis with the decrease of dissolved oxygen level in water at different temperatures, oxygen consumption rate and asphyxiation point were determined in juvenile filefish with body length of (9.5±0.08) cm and body weight of (15.34±0.15) g exposed to four temperature gradients of 12 ℃, 16 ℃, 20 ℃ and 24 ℃ in a closed breathing chamber. The results showed that the asphyxiation point was (0.85±0.06) mg/L at 12 ℃, (0.97±0.04) mg/L at 16 ℃, (1.10±0.05) mg/L at 20 ℃ and (1.40±0.07) mg/L at 24 ℃, and increased with the warming water temperature. The juveniles began to show uncomfortable behavior at dissolved oxygen levels close to 2.14 mg/L, 2.37 mg/L, 2.40 mg/L and 3.06 mg/L, and all appeared to death. The higher the temperature, the shorter the total death time of the juveniles when the dissolved oxygen content in each temperature group was decreased by close to 0.3 mg/L. The oxygen consumption rate was shown to be increased with the increase in temperature, and decreased from 0.104, 0.131, 0.187 and 0.318 mg/(g·h) at the beginning to 0.02-0.03 mg/(g·h) at the end with the decrease in dissolved oxygen content in the four temperature groups. The higher the temperature was, the faster the decrease was. The changes in oxygen consumption rate during the decrease in dissolved oxygen content in each temperature group were divided into suitable stage (Ⅰ), asphyxia stage (Ⅱ) and death stage (Ⅲ), with obvious changes in the three stages. There was a decreasing trend of the oxygen consumption rate in each group, with significant differences among the three stages (P<0.05). The oxygen consumption rate in each temperature group in stages Ⅰ and Ⅱ was increased with the elevated temperature, with the significant difference among all groups (P<0.05), without significant difference among adjacent temperature groups in stage Ⅲ (P>0.05), and with significant differences among the non-adjacent groups. Therefore, there was an obvious change in oxygen consumption rate in juvenile filefish with temperature change, the fish being poor hypoxia tolerance when oxygen consumption was higher.
