摘　　要： 本文观察了草鱼鱼种在人工饲养条件下生长率和血清生长激素水平季节性变化草鱼鱼种生长率存在明显的季节性变化，生长率在夏天（8月份）最高，而在冬天（1月份）最低，草鱼鱼种血清生长激素水平也存在明显的季节性变化，血清生长激素水平在夏天（8月份）最高，而在春天（4月份）最低对草鱼鱼种生长率和生长激素水平季节性变化。 The seasonal variations of body growth rates and serum GH levels of grass carp fingerling were studied. The body growth rates of grass carp fingerling are of significant seasonal variations, highest in summer (August) and lowest in winter (January). The serum GH levels of grass carp fingerling are also of significant seasonal variations, highest in summer (August) and lowest in Spring (April). The correlation of the seasonal variations of growth rates and serum GH levels with the seasonal variations of water temperature and day length were discussed.

关 键 词： 草鱼鱼种 生长率 生长激素 季节性变化
