| 中文摘要: |
| 为了研究光唇裂腹鱼（Ｓｃｈｉｚｏｔｈｏｒａｘｌｉｓｓｏｌａｂｉａｔｕｓ）的繁殖生物学，以采自珠江水系北盘江的３７尾卵巢成熟度为Ⅲ、Ⅳ期的光唇裂腹鱼标本为材料，用常规方法系统研究了该种鱼的个体繁殖力。结果表明，光唇裂腹鱼个体绝对繁殖力Ｆ为４５５～１０７１４粒，个体体长相对繁殖力ＦＬ为２．００～３７．２０粒／ｍｍ，个体体重相对繁殖力ＦＷ 为１８２～３７．２３粒／ｇ。相关分析显示，Ｆ、ＦＬ与其体长、体重、纯体重、卵巢重、年龄之间均呈显著性正相关，ＦＷ 与各项生物学指标之间相关性均不显著；Ｆ和ＦＬ与体长、体重、纯体重之间最佳拟合回归方程均为二次函数，与卵巢重之间的最佳拟合方程均为幂函数，而与年龄之间拟合度最好的方程则均为线性函数。复合分析、综合分析显示，体长、体重是影响光唇裂腹鱼个体繁殖力最重要的因素。 |

| The individual fecundity of Schizothorax Lissolabiatus was studied for the first time based on the 37 female individuals of the species with ovaries at III or IV stage from Beipan River belonging to the Pearl River system，China. The results showed that the individual absolute fecundity F varied from 455 to 10 714 eggs，the individual relative fecundities FL and FW, were 2. 00-37.20 eggs/mm and 1.82-37.23 eggs/g respectively. There were significantly positive correlation between F or FL of the species and each of standard length，body weight，dressed body weight，ovary weight and age of the individuals according to the correlation analysis. The best fitting equations were the quadratic function between F or FL and each of standard length，body weight，dressed body weight，while the power function between F or FL and ovary weight and the linear function between F or FL and age of the species. By means of the compound analysis and the synthesized analysis，it was found that both F and FL showed the closest correlation with the standard length and body weight respectively.
