| 摘 要： | 应用扫描电镜技术对体重范围在4.75～35.51g的浅色黄姑鱼（Nibea coibor）鳃结构及鳃小片进行了观察与呼吸面积计算,研究体重、体长与呼吸面积之间的相关关系。结果表明,浅色黄姑鱼的平均相对呼吸面积为4.01±1.62cm^2·g^-1。体重与一侧鳃丝总数的相关性N=28.81＋158.45lnW（R^2=0.9670,P〈0.01）较体长与一侧鳃丝总数的相关性N=17.31L^1.4542（R^2=0.8241,P〈0.01）更为显著。单位mm鳃小片的数目随着体重的不断增加显著减少,N=49.971W^-0.3909（P〈0.01）。单个鳃小片的面积随体重的增大而显著增加,a=0.3199W^0.2528（P〈0.01）。总呼吸面积随体重的增大而显著增加,A=11.559W^0.7109（P〈0.01）。相对呼吸面积随体重的增大而显著减小,RA=11.561W^-0.2904（P〈0.01）。

| Abstract: | The gill ultrastructure of Chu＇s croaker Nibea coibor with different body weight（4.75～35.51 g） was studied,as well as the relationship between individual size,life habit and the respiratory area.The results obtained were as follows：the average value of relative respiratory area of the N.coibor was 4.01±1.62 cm^2·g^-1.The total number of unilateral gill filament（N）was more closely correlated with body weight（W）（N=28.81＋158.45lnW,R^2=0.9670,P〈0.01）than with body length（L）（N=17.31L^1.4542,R^2=0.8241,P〈0.01）.The number of secondary gill lamella（N） per millimeter obviously declined by N=49.971W^-0.3909（P〈0.01）.The single secondary gill lamella area（a） significantly increased by a=0.3199W^0.2528（P〈0.01）,with the increasing of body weight（W）.Total respiratory area（A）was significantly positive correlated with body weight（A=11.559W^0.7109,P〈0.01）,while relative respiratory area（RA）was significantly negatively correlated with body weight（RA=11.561W^-0.2904,P〈0.01）. |
