摘　　要：通过将性成熟的中华鳑鲏(Rhodeus sinensis)亲本放入背角无齿蚌(Anodonta woodiana)不同壳宽组(50～100 mm)和不同壳宽的混合组中,观察中华鳑鲏产卵时对蚌大小的选择情况。中华鳑鲏在不同壳宽组中产卵实验结果显示,在蚌宽小于50 mm和大于90 mm的河蚌中的产卵率显著少于50～90 mm的蚌,其中60～80 mm产卵率显著多于其它组,70～80 mm被产卵率最高。中华鳑鲏不同壳宽组混养实验结果显示60～70 mm的河蚌被产卵率最高,显著高于其它组,大于70 mm和小于60mm被产卵率均逐渐下降。两个实验均显示出中华鳑鲏产卵时对河蚌的大小是有选择性的,本实验采用的1 g左右的中华鳑鲏最适产卵河蚌宽为70 mm左右。The choices of mussel（Anodonta woodiana）shell width when Chinese bitterling （Rhodeus sinensis ） spawn in different shell width groups （50 - 100 mm） and in mixed shell width groups were studied. The result showed that Chinese bitterling＇ s spawning rate in groups of shell width less than 50 mm and more than 90 mm were lower than the groups of shell width 50 -90 mm significantly. The spawning rate in groups of 60 - 80 mm were higher than other groups significantly, and the group of 70 - 80 was the highest. In the same way, the highest spawning rate of shell width was 60 - 70 mm in study of mixed shell width groups, which was higher than others significantly. The spawning rate declined when the shell width greater than 70 mm or less than 60 ram. The results in both of experiments indicated that Chinese bitterling （weight 1 g） might choose the right mussel, the best shell width of which was 70 ram.
