摘　　要：个性是动物个体之间在行为上表现出的稳定性差异,能量代谢为动物的个性行为输出提供能量支持,但二者之间的关联仍有争议。本研究以攻击性较强的叉尾斗鱼(Macropodus opercularis)为对象,考察了其标准代谢率(SMR)和个性行为之间以及不同个性行为彼此之间的关联。结果表明:叉尾斗鱼在行为上的个体差异较大;SMR与活跃性和攻击性指标中的平均速度呈显著正相关,表明SMR能较好地反映叉尾斗鱼活跃水平的高低;但SMR与攻击性的其他指标以及勇敢性均不相关,可能因为种内竞争导致的应激引起低等级地位的个体SMR升高,进而混淆了SMR与攻击性和勇敢性的关联;鱼类能量代谢与个性的关联较为复杂,叉尾斗鱼的SMR与个性关联较少可能与其较为激烈的种内竞争有关。Personality is the constant intraspecific difference in animal behaviors.Energy metabolism provides ener⁃gy for behavioral output.The relationship between energy expenditure and behavioral activities is still controversial.We investigated the correlation between standard metabolic rate(SMR)and personality,as well as the connection among different personality traits in a highly aggressive fish species,Macropodus opercularis.The results showed that there were significant inter⁃individual differences in behavior.SMR was positively correlated with the average veloci⁃ty during measurements of spontaneous activity and aggressiveness,indicating that SMR can reflect the activity level of M.opercularis.However,SMR was not related to any other indicators of aggressiveness and boldness.It might be due to the more profound increase of SMR in lower social status individuals as the consequence of stress caused by intraspecific competition,which may obscure the relationship between SMR and most of personality traits.Our results suggested that the relationship between energy metabolism and personality in fish was quite complex,and that the weak correlation between SMR and personality in M.opercularis might be due to intense intraspecific com⁃petition.
