Rapid Action Fund

Organisation: PROGRES

Project title: Urgent conservation action for three Critically Endangered fishes endemic to Lake Poso, Sulawesi, Indonesia

Location: Sulawesi, Indonesia

Project date: March 2022 – March 2023 (ongoing)

Species: Duck-billed Buntingi Adrianichthys kruyti, Rosen’s Buntingi Adrianichthys roseniPoso Bungu Mugilogobius amadi 

Supported by: Fondation Segré

The challenge

Lake Poso in Sulawesi is one of the world’s oldest lakes, a Key Biodiversity Area and an Alliance for Zero Extinction site. It supports a high degree of endemism of many freshwater species, including 10 endemic fish species, 3 of which are Critically Endangered (Possibly Extinct): Duck-billed Buntingi, Rosen’s Buntingi and Poso Bungu. The drastic declines of these three species are largely considered to be due to predation by alien fishes in the 1970s which have since become invasive.  

In addition, a large hydroelectric dam project approved in 2005 has resulted in widespread dredging and reclamation, threatening the unique ecosystem of the lake and the traditional fishing approaches of the lake’s fishing community.  

The project

PROGRES aims to conserve the three Critically Endangered fishes in Lake Poso by conducting extensive surveys to determine if these species still persist, and ascertain population status and distribution. As part of the survey work, they will identify the key threats and potential for population recovery, including potential need for an ex situ breeding programme. The team will engage with the local community to garner support for the conservation of the lake and the fishes and consult local stakeholders to develop a conservation plan for the Lake Poso landscape.
