摘要
主要报导长江原种亲鱼鲢、鳙、草鱼和青鱼的形态特征、年龄生长和繁殖特性。通过可数可量参数的测定，年龄生长、性成熟年龄、繁殖力、成熟系数及卵比重等单项的和相对关系的研究，讨论并提出了原种亲鱼鲢、鳙、草鱼、青鱼的标准参数，可供原种场生产管理，原种检测及种质资源保护作为依据。
This paper reports the characteristics of morphology, age, growth, reproductivity of brooders of silver carp, bighead carp, grass carp and black carp originated from the Yangtze River.Based on the studies of single characters and relative comparison of measurable and meristic characters, age-growth relation, age of maturity, fecundity, gonadosomatic index, egg gravity, parameters for criteria of brooders of these speices were proposed, which would be used for the management of original fish farm, inspection of brooders and genetic conservation.
