Bighead Carp
Hypophthalmichthys nobilis
Ikan Kap Kepala Besar,
name in chinese characters

Primarily freshwater fish; 100 cm; oviparous; filter-feeder; gregarious; pelagic.
Introduced, popular pond-culture fish. Rural ponds and reservoirs (often in floating net cages).

The disproportionately large head of this fish, originally Chinese, is often used for making the delicious Chinese dish "clay-pot fish-head". In a number of the catchment reservoirs (e.g., Seletar and Pandan), it is kept in floating net cages to help control microscopic floating plankton, as well as to generate revenue from the sale of adults. The fishes filter plankton from the water (the main part of its diet) with gill rakers adapted to form a filtering apparatus. This well known species was previously classified in the genus Aristichthys.
