When Do Crucian Carp Spawn? A Detailed Guide to the Spawning Season

The crucian carp is a very popular fish. Not only is it easy to breed, but it is also convenient to manage. It generally spawns when it grows to March, so many people like to farm it to make money. So when do crucian carp spawn?

1. When do crucian carp spawn?

Crucian carp generally spawn from March to July, with April being the peak breeding period. However, due to climate differences between north and south, the spawning time also varies. For example, in the southern region, the spawning peak in the Pearl River basin is from February to March, in the Yangtze River basin from April to May, in the Yellow River basin from May to June, and in the northeast region from June to July. The spawning period generally lasts about 2 months.

2. How many days does it take for crucian carp eggs to hatch into fry?

Generally, it takes 3-7 days from the laying and fertilization of the eggs to the hatching of the fry. If the average water temperature is 15-20°C, the hatching time is 5-7 days; if the average water temperature is 20°C, the fry can hatch in 4-5 days; if the average water temperature is 20-25°C, it takes only 2-3 days. In short, the lower the water temperature, the longer the hatching time.

Overall, crucian carp can spawn as early as March, but due to climate differences between north and south, some do not spawn until June-July, so the specific timing depends on the local climate.
