How long does it usually take for crucian carp to throw seeds?

Speaking of fishing, I believe many people like it very much, and many friends often join the ranks of fishing. For new friends, it is generally not clear how long it will end. Under normal circumstances, crucian carp seed throwing begins in the early hours of the morning and ends around nine o'clock. Usually, it is easy to lay eggs in foggy or rainy days. It is easy to lay eggs when the temperature is over 16 degrees in spring or in autumn when the temperature is suitable. As long as it's time to lay eggs, the male will always chase the female. In fact, this is a courtship behavior. In addition, when the female fish matures, she will release some information before ovulation, so that the male fish can come and chase. When the male fish collides with the female fish's abdomen, it will make the male fish release semen faster.
