How does red carp divide male and female

Red crucian carp can be divided into male and female in three ways. The first one looks at the body size, the one with an enlarged abdomen is the mother, and the thin elder is the male; the second one looks at the anus, the wide and flat anus is the female, and the small and invaded anus is the male; the third looks at the tail, and the female fish slowly becomes smaller from body to tail, while the male fish mutates less at the anus. Fish of the same size have small female scales and large male scales.

The detailed method of dividing male and female of red crucian carp:

The male and female of red crucian carp can be distinguished by looking at fish body, fish head, tail, fish scale, anus, figure, genitalia and so on. Generally speaking, females of the same age from the same producing area are always larger than males.

1. Look at the body of the fish: the male fish is thin and the female fish is short and wide. There is also a distinction on the tail, the female fish slowly becomes smaller from body to tail, the male fish has a small mutation in the anus, the same size of the female scale is small, the male scale is large, the head is big, the male head is small, the male crucian carp body image is small carp.

2. Look at the figure: those with enlarged abdomen are female, and the thin elders are male.

3. Look at the anus: the wide and flat anus is female, the anus is small and invaginated is male.

4. Look at the star chase: those who have no star chase on the fin are female, and those who have star chase are male.

5. Look at the fins: touch the fins with your hands. If there is a rough horny protuberance, it is a male and a smooth one is a female. Mature male fish gently press on the abdomen and white semen will flow out. Sexually mature and healthy golden carp, gold crucian carp and goldfish, all can reproduce on their own during the breeding period. Look at the fish fin under the gills and gills, the prominent white spot above is the male fish, and no white spot is the female fish.

6. Crucian carp are generally more female, the female body is generally shorter but wider, the male half is longer and narrower, and from the point of view of the reproductive pore, the female half of the abdomen is relatively dilated, the touch is relatively soft, and the ribs are obvious. the fan-shaped half of the pectoral fin is female, and the long half of the pectoral fin is male. Put some water plants in the tank, after a period of time, the female fish will attach the eggs to the grass, do not worry about changing water, but it is best to change less, do not change more than 1/3 water each time, and pay attention to the temperature difference between the two kinds of water as small as possible.

The above is the introduction of red crucian carp how to divide male and female. I hope it will be helpful to everyone.
