瓦氏黄颡鱼是一种长江流域广泛分布的小型经济鱼类,现已成为广大养殖者乐于接受的重要新兴养殖对象.为探明其基础生物学特性,给养殖生产提供技术指导,采用基础生物学研究方法,对洞庭湖瓦氏黄颡鱼的外部形态、年龄和生长、繁殖力等生物学特性进行了初步研究 .结果表明:洞庭湖瓦氏黄颡鱼鳍的特征为D.2,6～7;A.20～26;P.1,7～9.其体长(L ,cm)和体重(W,g)关系方程为W=0.041 L2.92.生长方程为:Lt= 2 2.76[1-e-0.327(t+1.194)],Wt= 378.3[1-e-0.327(t+1 .194)]3,该鱼的绝对繁殖力为576～8 346粒,相对繁殖力平均为61.6粒/g.绝对繁殖力与体长的关系符合F= 5.111L2.617.

Pelteobagrus vacleii ,a small sized fish of econmic value,living in the waters of the Changjiang River valley,has become a new cultured fish.In order to explore the basic biological features of Pelteobagrus vacleii and provide technical guide for its culture production,the morphologies, growth ratio and reproductive capacity of Pelteobagrus vacleii from Dongting Lake of China were studied by using research methods of basic biology. Results show that Pelteobagrus vacleii fins pattern fits the form of D.2, 6～7;A.20～26;P.1, 7～9.The relationship...
