1986; Chen 2010）。自1986年以来，大多数地区的人口减少或消失。物种现已从纳帕湖灭绝。大部分现存个体生活在碧塔湖，少数生活在小中甸河和纳亚河（Wang and Xie，2004）。生境与生态：幼鱼分布于湖、溪的沿岸的地带，成鱼栖息于湖的中、下层。繁殖：6月，个体从湖中返回溪流产卵。雄性用臀鳍鳍条挖坑并在坑中产卵。亲鱼在每年7月至9月间多次产卵。威胁：生境退化、水污染、过度开发和外来物种。最值得注意的是，斯威霍氏小鲈的入侵是一个严重的威胁。保护行动：自1984年建立碧塔海省级自然保护区以来，碧塔海及其周围的原始森林得到了很好的保护。中甸县人口状况监测
1986; Chen 2010). Abundance: Since 1986, populations have declined or disappeared in most areas. Species is now extirpated from Lake Napa. Most remaining individuals are in Lake Bita with a few in Xiaozhongdian River and Naya River (Wang and Xie 2004). Habitat and ecology: Juveniles occur in the littoral zone of the lake and streams; the adults inhabit the middle and lower water layers of the lake. Reproduction: Individuals return from the lake to streams to spawn in June. Males dig pits with anal fin rays and lays eggs in the pit. Parental fishes spawn several times from July to September every year. Threats: Habitat degradation, water pollution, over-exploitation and exotic species. Most notably, Micropercops swinhonis invasion is a critical threat. Conservation actions: Lake Bita and primary forest around the lake have been well protected since 1984 by establishing Bitahai Provincial Natural Reserve. A population status monitoring of Chungtien
