Abstract

In 2018 we captured specimens of Oreachromis niloticus (Linnaeus, 1758) from Danau Kastoba, a crater lake on Bawean (Indonesia), a small, isolated island in the Java Sea. Additional individuals were later photographed. These records are among first of this species from an isolated island, in the Java Sea. A description of meristic and morphometric features of a specimen are provided.
