Crucian carp is a freshwater fish with strong reproductive capacity. They are relatively early, and some crucian carp have the ability to reproduce when they are about one year old, and then they can reproduce in the breeding season, which starts in March or April every year, and different regions will have different climates.
Crucian carp can reproduce and spawn more than once in each breeding season, generally speaking, it can reproduce at least twice. After one spawning, they rest for a month or a few months and then go on to the next reproductive spawning process. Specifically, the reproductive frequency of different varieties of crucian carp is also different. For example, "red crucian carp" this species, they can reproduce 3-4 times a year, in the breeding season, basically every month can reproduce and spawn once.
As mentioned above, the reproductive capacity of the crucian carp is relatively strong, not only because their reproductive age is relatively early and they can reproduce many times in each season, but also because there is an important reason that the number of eggs laid by the carp at each time is large. Specifically, the number of eggs laid by crucian carp at different ages is different. Crucian carp that has just reached the age of sexual maturity will lay slightly less eggs, but it can also reach more than 10000 eggs; Later, with the increase of the age of crucian carp, the number of eggs will also increase, if the crucian carp over 5 years old reproduce and spawn, the number of eggs can reach 100000 or more. In addition, the number of spawning of different varieties of crucian carp is also different, such as the "red crucian carp" mentioned above, the number of spawning is more.
Of course, although the number of fish eggs is relatively large, not all fish eggs can be fertilized, and not all fertilized eggs can be hatched, and the hatched small fish may also die for various reasons. Under suitable environmental conditions, the success rate of reproduction will be relatively high.
