Description of life cycle and mating behavior | 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. |
