研究了南四湖大鳞副泥鳅的生态特征。结果表明:南四湖大鳞副泥鳅形态变异具有统计学意义,消化道重量、长度分别与体重呈极相关、相关,种群年龄结构偏小,怀卵量与体重相关。
The ecological characteristics of Paramisgurnus dabryanus in Nansi Lake were studied. The results showed that the morphological variations of Paramisgurnus dabryanus in Nansi Lake were statistically significant. The weight and length of digestive tract were highly correlated with body weight, respectively. The age structure of the population was small, and the amount of egg was correlated with body weight.
