The results indicate that the standard metabolic rates increase with the increase of body weight at different temperatures. Relationship between them could be described as Rs = a ln W b. The mean of standard metabolic rate is significantly different among groups, but the b values are not. The standard metabolic rates of amended standard body weights decrease with the increase of temperature, and the mean of standard metabolic rate is also significantly different among groups when the standard body weights are 48.6 g, 147.9 g, and 243.1 g. Relationship between them could be described as Rsw = m e-b/T. The relations of standard metabolic rate ( Rs ) or relative metabolic rate ( Rs ) to body weight and temperature yield the following equations: Rs = 1.160 W 0.752 e -9.494/ T and Rs’= 1.160 W 0.254 e -9.494/ T.展开更多
测量并分析了沙塘鳢(Odontobutis obscurus(Temminck et Schlegel))的体重、体长、全长、体宽、体高、头长、眼间距、吻宽和尾柄高及其相互关系,除体长与体重的关系以模型y=ax^b拟合较好外,体长与其它长度指标的关系均以模型y=a+bx拟合...测量并分析了沙塘鳢(Odontobutis obscurus(Temminck et Schlegel))的体重、体长、全长、体宽、体高、头长、眼间距、吻宽和尾柄高及其相互关系,除体长与体重的关系以模型y=ax^b拟合较好外,体长与其它长度指标的关系均以模型y=a+bx拟合较好。随着体长的增加,体高/体长、眼间距/体长和吻宽/体长等指标均显著增加,这表明,随着沙塘鳢的生长,鱼类的体型一直在发生变化。展开更多
