英文摘要	In recent years, threat to nearshore marine ecosystems and marine organisms caused by seawater acidification and seawater warming are becoming increasingly serious. In order to study the effects of CO_2-driven ocean acidification and warming on growth and energy budget of the sea cucumber Apostichopus japonicus, which is a key species in the coastal ecosystem of East Asia, four experimental treatments were set up, namely, control (seawater temperature of the Dalian coast, pCO_2 400 muatm), ocean warming (OW, seawater temperature of the Dalian coast plus 3℃, pCO_2 400 muatm), ocean acidification (OA, seawater temperature of the Dalian coast, pCO_2 1100 muatm) and Ocean acidification and warming (OAW, seawater temperature of the Dalian coast plus 3℃, pCO_2 1100 muatm). The result showed that A. japonicus in OW were not significantly affected in contrast to control. However, the specific growth rate (SGR) of A. japonicus in OA was the lowest, which decreased by 0.19%/d compared with the control treatment, and the body weight Coefficient variations of A. japonicus in OA was the largest. The final body weight and SGR of A. japonicus in OAW showed no significantly difference with those in control, bur ingestion rate and feces production rate were both significantly higher than those in the control. The bioenergetic pattern of A. japonicus in OW and OA did not change significantly compared with that in the control, but it changed significantly in OAW, with the percentage of the FCE being significantly higher than the other three treatments. Our study suggests that seawater acidification inhibited the growth of A. japonicus versus change its energy distribution pattern. The decrease of growth in OA mainly depended on the decrease of food ingestion. The combined effect of seawater acidification and rising temperature may compensate for the negative effect of seawater acidification on growth by changing the energy distribution pattern of A. japonicus.
中文摘要	以东亚浅海生态系统中的关键种——刺参(Apostichopus japonicus)为实验对象,研究了CO_(2)驱动的海水酸化及升温对其生长及能量收支的影响。实验设置对照组(大连近海水温,pCO_(2)400μatm)、升温组(大连近海水温+3℃,pCO_(2)400μatm)、酸化组(大连近海水温,pCO_(2)1100μatm)和酸化升温组(大连近海水温+3℃,pCO_(2)1100μatm)。结果表明:与对照组相比,温度升高3℃对刺参的生长无显著影响;酸化组刺参的特定生长率最低,较对照组降低0.19%/d,个体体重的变异系数最大;酸化升温组刺参的终末体重和特定生长率与对照组相较无显著差异,但其摄食率和排粪率均显著高于对照组。升温组和酸化组的刺参能量的分配模式与对照组相比未发生明显改变,但酸化升温组刺参的能量分配模式发生显著变化,其粪便能所占摄食能的比例显著升高。研究表明,海水酸化抑制了刺参的生长但未改变其能量的分配,生长的降低主要取决于摄食减少;而海水酸化与温度升高的共同作用可能会通过改变刺参的能量分配模式而弥补海水酸化对生长带来的负面影响。
