(Adrianichthys kruyti)

syn. -


Indonesia: Lake Poso / Sulawesi

local name: -

size: ca. 16 cm (length)

extinction date: last seen between 1976 and 1985

The Lake Poso is located at about the centre of the island of Sulawesi, at an elevation of about 600 m, it has a surface area of about 300 kmē, and is at its deepest point up to 450 m deep.


The Duck-billed Buntingi is one of the endemic fish species of the Lake Poso.

The biology of this up to 16 cm long fish species is virtually unknown.

The introduction of predatory fishes, including Striped Snakehead Murrel (Channa striata (Bloch)), and Mozambique Tilapia (Oreochromis mossambicus (Peters)), lead to the disappearance of the Duck-billed Buntingi, and finally to its complete extinction.
