We surveyed the reproductive ecology of Cobitis minamorii minamorii in paddy fields and ditches. The spatial distribution of females in the spawning season differed from that in the non-spawning season, even in short ditches. Eggs were collected in both ditches and paddy fields, unlike an earlier study demonstrating that no eggs were collected in ditches. The frequency distributions of standard body lengths of males and females were unimodal and bimodal, respectively. The females with a large standard body length were expected to be gravid with higher probability in May.

稻田和沟渠中南氏鲟的繁殖生境利用、体型结构及产卵期

我们调查了稻田和沟渠中的南氏鲟的生殖生态。产卵期雌鱼的空间分布与非产卵期不同，即使在短沟中也是如此。鸡蛋是在沟渠和稻田中收集的，这与早期的研究表明没有鸡蛋收集在沟渠中不同。雄性和雌性标准体长的频率分布分别为单峰和双峰。预计标准体长较大的雌性在5月份怀孕的概率较高。
