1 Oocyte diameter 1.20-1.36 [Egg before swelling] 1.28 mm Mikodina and Makeyeva, 1981
2 Egg size after water-hardening 5.6 [Eggs swell four to five fold during hydratation] 5.6 mm Crosier et al, 2005
2 Egg size after water-hardening 3.40-4.40 [Egg after swelling, the membrane diameter increases 3-5 times] 3.9 mm Mikodina and Makeyeva, 1981
2 Egg size after water-hardening After the eggs have been fertilized and have absorbed water, the egg membrane expands to about 5-6 mm 5.5 mm Naca, 1989
3 Egg Buoyancy Bathypelagic and carried by currents Pelagic Crosier et al, 2005
3 Egg Buoyancy Eggs developp in pelagic water of the river current [The buoyancy of the egg is achieved by the penetration under the membrane of a considerable amount of water and the creation of perivitelline space] Pelagic Mikodina and Makeyeva, 1981
3 Egg Buoyancy Pelagic Pelagic Fishbase, 2006
3 Egg Buoyancy Develop in pelagic water Pelagic Kunz, 2004
3 Egg Buoyancy The eggs of chinese carps are semibuoyant and are carried by currents until they hatch Pelagic Scholfield, 2005
3 Egg Buoyancy Having a greater specific gravity than water, eggs sink to the bottom in still water; yet, they are semi-buoyant in a current, floating until the fry hatch Demersal Naca, 1989
4 Egg adhesiveness Slight stickiness, manifested only in the first 2-3 minutes in water Adhesive Mikodina and Makeyeva, 1981
4 Egg adhesiveness Characterized by slight stickiness (due to acid mucopolysaccharies on the surface of the envelope) observed only in the first 2-3 minutes Adhesive Kunz, 2004
4 Egg adhesiveness The eggs are seperated and nonadhesive Non-Adhesive Naca, 1989
6 Temperature for incubation The optimum temperature is between 25 and 27°C 25.0 °C Naca, 1989

30 Male sexual dimorphism The pectoral fin rays are thick and long, extending freely like sharp knives. In the reproduction season, pearl organs appear on the pectoral fins and opercula of mature male fish. They are coarse to the touch Absent Naca, 1989
