Abstract

An experiment was conducted to investigate the effects of three water temperatures (15, 20 and $25^{\circ}C$) in combination with three salinities (0, 15 and 30 psu) on the oxygen consumption rate of juvenile spotted sea bass, Lateolabrax maculatus (mean body weight $5.5{\pm}0.3g$). The oxygen consumption rates of L. maculatus were measured in triplicate for 24 hours using a continuous flow-through respirometer. Water temperature resulted in significant differences in the mean oxygen consumption rate of L. maculatus (p<0.001), but salinity and combinations of salinity and water temperature did not have (p>0.05). The oxygen consumption increased with increasing water temperatures in all experimental salinity regimes (p<001). Mean oxygen consumption rates at 15, 20 and $25^{\circ}C$ ranged 328.8~342.3, 433.9~441.0 and 651.5~659.9 mg $O_2\;kg^{-1}\;h^{-1}$, respectively. $Q_{10}$ values did not vary with salinity, bud varied with water temperature. $Q_{10}$ values ranged 1.63~1.75 between 15 and $20^{\circ}C$, 2.24~2.26 between 20 and $25^{\circ}C$, and 1.92~1.98 over the full temperature range. The energy loss by metabolic cost increased with increasing water temperatures in all experimental salinity regimes (p<0.001) Mean energy loss rates at 15, 20 and $25^{\circ}C$ ranged 224.6~233.8, 296.3~301.2 and $444.9{\sim}450.7kJ\;kg^{-1}\;d^{-1}$, respectively. These data suggest that the culture of juvenile spotted sea bass is possible without energy loss by salinity difference in freshwater as well as seawater after salinity acclimation. Thus, this result has an application for culture management and bioenergetic model for growth of this species.

점농어 치어의 수온과 염분에 따른 대사율 변화를 조사하기 위해 평균 무게 $5.5{\pm}0.3g$인 개체를 대상으로 수온 (15, 20, $25^{\circ}C$)과 염분 (0, 15, 30 psu)에 따른 산소 소비율을 측정하였다. 9가지 실험 조합의 산소 소비율은 유수식 형태의 호흡실을 이용하여 24시간 동안, 3반복 측정하였다. 수온은 점농어 치어의 산소 소비율에 유의한 영향을 미쳤지만(p<0.001), 염분과 수온 염분의 상호작용은 영향을 미치지 않았다(p>0.05). 각 염분 조건에서 수온 상승에 따라 산소 소비율은 유의적으로 증가하였다(p<0.001). 15, 20 그리고 $25^{\circ}C$에서의 시간당 평균 산소 소비율은 각각 328.8~342.3, 433.9~441.0 그리고 $651.5{\sim}659.9mg\;O_2\;kg^{-1}\;h^{-1}$이었다. $Q_{10}$ 값은 염분의 영향은 받지 않았으며, 수온에 따라 변하였다. 15~20, $20{\sim}25^{\circ}C$ 그리고 전 수온 범위에서의 $Q_{10}$ 값은 각각 1.63~1.75, 2.24~2.26 그리고 1.92~1.98이었다. 대사에 의한 에너지 손실은 수온의 증가에 따라 유의하게 증가하였다(p<0.001). 15, 20 그리고 $25^{\circ}C$에서의 호흡 대사로 인한 일간 평균 에너지 손실은 각각 224.6~233.8, 296.3~301.2 그리고 $444.9{\sim}450.7kJ\;kg^{-1}\;d^{-1}$이었다. 이 실험 결과는 점농어 치어를 염분 적응 후 염분 차이에 의한 에너지 손실 없이 해수뿐만 아니라 담수에서 사육이 가능하다는 것을 나타내며, 사육관리 및 성장을 위한 생체역학 모델 결정에 활용할 수 있다.
