提高大鲵子二代苗种成活率技术初报

A primary report of the improvement of survive rate of F_2 giant salamanders

研究结果如下：（1）久效磷改变了细小色矛线虫子一代和子二代的种群动态。

Results showed : ( 1 ) The population dynamics of the first and second offspring of C. germanica were changed by monocrotophos .

子二代鸟在生长速度方面与子一代鸟比较，表现为平均日增重曲线峰值前移和达90公斤体重的饲养月龄提前一个月。

Ln compar is on to the first filial generation , the second filial generation grew faster and the curve for daily weight gain put forward .

系统研究了影响大鲵子二代孵化率的环境因子（包括水质、水温、孵化密度）、硬件设施和软件管理技术。

The study systematically researched on the effect of environment factors such as water quality , water temperature , incubation density as well as incubation facilities and management technique to the hatching rate of the Chinese giant salamander .

通过统计子一代及子二代的性比，初步认为稀有鮈鲫性别决定机制复杂，其常染色体上的因子可能参与了性别决定。

Based on the results from scoring sex ratios in the F1 and F2 progenies , a complex mechanism of sex determination in rare minnow was proposed , and factors on autosomal chromosomes might have influenced on its sex in this study .
