1. Appearance color is different: there is little difference between golden crucian carp and common crucian carp, but the body color of golden crucian carp is golden yellow and the abdomen is white, while the back of common crucian carp is bluish gray and the abdomen is white.

2. Different breeding methods: The gonad of Carassius auratus is not very developed, so it cannot reproduce itself. They are all triploid fish, but they need artificial induction, so there is no need to worry about being mixed with other species when breeding; However, crucian carp has developed gonads and strong reproductive ability.

3. Different growth speed: Compared with common crucian carp, golden crucian carp grows faster because it is not limited by sexual maturity.

4, individual size is different: the largest individual of golden crucian carp can reach more than 3 kg, while ordinary crucian carp is generally less than half a catty, and more than 1 kg is considered very large.

Golden crucian carp is obtained by distant hybridization with scaly mirror carp as female parent and red crucian carp as male parent, which can be cultured in ponds all over the country. The fish has the characteristics of strong cold tolerance, long feeding time, good stress resistance, fast growth and strong disease resistance.

Crucian carp (Carassius auratus) is a common freshwater fish in China, and generally lives in the main water system outside the Qinghai-Tibet Plateau. The fish is omnivorous, with wide feeding range, strong reproduction, fast growth and low requirements for water temperature.
