| The effects of water temperature on oxygen consumption (OC) of starry flounder Platichthys stellatus reared in seawater (SW) and freshwater (FW) was performed in closed water-recirculating system containing respiratory chamber. Fish acclimated in separate indoor tanks with SW (nine of fish used, $263.0{pm}40.4$ g) or FW (nine of fish used, $265.8{pm}34.8$ g) were sampled. The OC of starry flounder at $15^{circ}C,;20^{circ}C$ and $25^{circ}C$ were $74.4{pm}17.0,;85.9{pm}15.8,;98.3{pm}11.4;mg;O_2;kg^{-1}hr^{-1}$ in SW and $46.7{pm}12.0,;63.3{pm}7.5,;82.6{pm}5.3;mg;O_2;kg^{-1}hr^{-1}$ in FW, respectively, showing a linear increase in OC with water temperature. The OC of fish reared in both SW and FW clear diel rhythm, with lower values at daytime and higher values in the night, in accordance with light (09:00~21:00 hr) and dark (21:00~09:00 hr) phases of the diel cycle (12L : 12D) in water temperature at $15^{circ}C$ and $20^{circ}C$. However OC of fish reared in both SW and FW showed unclear diel rhythm with light and dark phases of the diel cycle in water temperature at $25^{circ}C$. Starry flounder reared in FW had higher ventilation rates than those in SW, but SW had higher OC per breath than those in FW. |
