Fishes of Billiton (1851–1939)

Two historical scientific publications document the island's marine and freshwater fish fauna, from Pieter Bleeker's 1851 report to L. F. de Beaufort's study of collections made in 1936–1937.

1851 · Early marine fish records

In Visschen van Billiton, Pieter Bleeker reported ten marine fish species collected on Billiton by Dr. J. H. Croockewit Hz. and passed to him in Batavia. Bleeker described Belone leiuroïdes as new to science at the time. His report is dated Batavia, 26 February 1851.

The ten species listed by Bleeker (historical names and spellings)
No.Species in the 1851 source
1Mesoprion russellii
2Mesoprion annularis
3Helotes sexlineatus
4Sillago acuta
5Platycephalus insidiator
6Dentex tambulus
7Pentapus setosus
8Platax bataviensis
9Belone leiuroïdes
10Solea pan

Bleeker's names are reproduced as historical records; this is not a modern taxonomic checklist.

1936–1937 · Freshwater collections

F. J. Kuiper collected freshwater fishes from different streams on Billiton in 1936 and 1937, presenting the specimens to the Zoological Museum of Amsterdam. L. F. de Beaufort published the study in Treubia in 1939.

41Species in Kuiper's collection
22Species not previously reported from Billiton
2Species described as new in this paper

Two newly described species

Nemachilus kuiperi was named for the collector Kuiper. The original paper illustrates this small loach on printed page 190. Mastacembelus billitonensis, a spiny eel, is described on printed pages 194–195. These are historical original combinations; current taxonomy may differ.

Fish habitats and the island's rivers

De Beaufort distinguished fish collected in the lower, middle and upper courses of rivers. The middle course yielded the greatest number of species. He also discussed how the freshwater fauna of Billiton relates to Sumatra, Banka and Borneo, interpreting these patterns through the ancient river connections of Sundaland.

These are historical observations and interpretations, not a complete modern inventory of the island's fishes.
