  • Reproduction : breeds in spring through to midsummer after the first substantial rains of the season. Migrates upstream to spawn over suitable gravel beds. Breeds in flowing water therefore must ascend the rivers to spawn in gravel beds. Eggs are laid in a shallow saucer like nest which is constructed in the gravel by a female (or perhaps male) using the snout and caudal fin. Eggs are covered with gravel after fertilization. A 45 cm female carries 30,000 eggs .

    • Cyprinus aeneus Burchell, 1822: 280, fig. Type locality: "Zak River". No type.
  • Use and trade : a very popular angling species and highly prized by flyfishers because of its aesthetic appeal (fish are golden yellow in summer) and fighting qualities. It is also a popular subsistence species, with large numbers of fish caught by poor rural people .
