Conservation Actions

The control of invasive species within Lake Lindu is recommended, as they are very abundant within the lake and could pose a significant threat. Surveys are also recommended to monitor the population trend of this species.

Location Information

This species is endemic to Lake Lindu in Central Sulawesi, Indonesia, which lies to the north-west of the larger Lake Poso.

Geographic Range



Population Information

The population of this species is thought to be stable (D.F. Mokodongan pers. obs. 2017, M. Herjanto pers. comm. 2018), although it may decline in the future from the impact of introduced species.


Lake Lindu is threatened by a number of different factors. Three species of introduced fish are known to occur in the lake, which are the Mozambique Tilapia (Oreochromis mossambicus), the Common Carp (Cyprinus carpio) and the Walking Catfish (Clarias batrachus). These were first introduced into the lake in the 1950's to increase commercial fish production, but have now become the most common fish in the lake. The introduction of tilapia is thought to have led to the near extinction of indigenous fish species and mussels in the lake through competition and direct predation. The lake is also threatened by the expansion of agricultural land and human disturbance and livestock grazing at the lake banks, which modify the lake ecosystem through changes in turbidity and sedimentation (Annawaty et al. 2016). Water quality declines due to domestic runoff may also be occurring (J. Sulfani Udin pers. comm. 2019). As the species is thought to have a stable population trend, these threats are not thought to currently be causing significant declines, however they may cause declines in the future.
