摘要
本文研究了6种鲤科鱼类的呼吸面积和体重变化对鳃小片面积,鳃小片间距、呼吸面积等的影响。3种小个体种类较大个体种类相对呼吸面积大,活动性较强的凶猛鱼类相对活动呼吸面积较大,鲢鱼随体重增加鳃小片间距和相对呼吸面积非线性减小,两鳃丝数、鳃小片面积和总呼吸面积呈非线性增加。鲢鱼体重(W,g)与总呼吸面积(A,mm^2)和相对呼吸面积(RA,mm^2/g)的关系式为: A=1.23×10~4W^(0.781),r=0.901,n=7; RA=2.96×10~4W^(-0.399),r=0.947,n=7。
This paper deals with respiratory area of gill of several Cyprinid fishes, and scaling or effect of fish size on the area of seconary lamella, disdance between lamella, respiratory area of gill and so on.The respiratory area of 3 small size fish species is larger than that of big size ones, and the respiratory area of active fishes is larger than that of more or less sluggish ones. With increse of weight, the disdance of secondary lamellae of Silver carp and relative respiratory area decrease non-linearly, but the number of filaments, area of a single secondary lamella, whole respiratory area increase non-linearly.The formulae of weight (W,g) of Silver carp with its respiratory area (A,mm2) and relative respiratory areaA = 1.23×104W0.781, r=0.901,n = 7;RA = 2.96 ×104W-0.399, r = 0.947,n = 7.
