How carp reproduce and when to reproduce

Temperature: When the water temperature rises above 18 in spring, the carp begins to spawn and reproduce, and the suitable water temperature for breeding and spawning is about 25.

Water velocity: The suitable water velocity for carp spawning and reproduction is.

Attachments: When carp spawn, there are aquatic weeds, branches and other fish eggs that can be attached in the waters, and if there are no attachments, the carp gonads will not spawn when they are mature.

1. What are the conditions for carp reproduction?

1. Temperature. 1) In spring, when the water temperature rises above 18, carp can spawn and reproduce.

2) The suitable water temperature for carp spawning and breeding is about 25.

2. Water flow velocity.

Carp need to have a slight flow of water when spawning, and the water flow speed is appropriate.

3. Attachments.

Carp eggs are sticky eggs in sinking eggs, and the outer layer of the egg membrane has a sticky substance, which can adhere to aquatic plants, tree branches and other objects after production. If there are no eggs to attach to in the waters, the gonads of the carp will not spawn even if they are mature.

2. How long is the breeding period of carp

1. Breeding period.

1) The spawning period of carp is about 2 months.

2) If it is in the southern region, the peak spawning period is generally from February to March every year. If it is the Yangtze River basin area, the peak spawning period is generally from March to April every year. If it is in the Yellow River Basin, the peak spawning season is generally from April to May every year.

In the case of the Tohoku region, the peak spawning season is generally from May to June every year.

2. Sexual maturity.

1) If it is a carp that matures late, it is generally 2 winter years old before it can spawn. If it is a carp that is sexually mature early, it is generally 1 winter old and can spawn when it weighs more than 1 kg.

2) Taking carp in the Yangtze River basin as an example, March to May is the sexual maturity and spawning period. After spawning, the female carp's stage VI ovaries degenerate to stage II in July of the same year, and the subsequent ovaries gradually develop until they enter stage IV in November and overwinter. In March and April of the following year, when the environmental conditions are suitable, the ovaries of female carp rapidly develop from stage IV to stage V.

After breeding, the male carp degenerated to stage III, entered stage IV from August to September of that year, and entered stage V in December of that year, and overwintered.

1. Carp lay sticky eggs and need attachments so that the fertilized eggs can adhere to them and develop.

2. Carp can spawn naturally in general rivers, lakes, swings and ponds, and when the water temperature rises above 18 in spring, it begins to spawn and reproduce.

3. Carp are generally sexually mature in the second instar, and some individuals can also mature in the first instar. The spawning season varies from region to region, and spawning can be performed from March to August (with April to June as the peak season), and it is a batch spawning type. The spawning ground is mostly in the shallow lake bay or river bay aquatic grass clustered area, the egg stickiness is very strong, after the lay, it is firmly adhered to the aquatic weeds, the amount of eggs conceived varies according to age and individual size, ranging from 15-800,000 grains, after the egg is produced, the seedlings can be hatched after 4-6 days at 15-20 water temperature.

4. There is no hard shell protection outside the egg.

It can mature in the 3rd year.

In general, males of the right age can reproduce at least two years old and females at least three years old. The most suitable breeding period is 3 6 years old for males and about 4 10 years old for females.

Carp is a benthic omnivorous fish that eats both meat and vegetables. The bait spectrum is extensive, the snout bone is well developed, and it often arches mud to feed. Carp is also a low-level ectothermic animal, and its body temperature changes with the change of water temperature, so it does not need to rely on energy consumption to maintain a constant body temperature, so the total amount of bait to feed is not large.

At the same time, carp, like most freshwater fish, belongs to the stomachless fish species, and the intestine is short, and the metabolism is fast, so the feeding habit is to eat less and eat frequently. The digestive function of carp is highly dependent on water temperature, and feeding seasonality is strong.

1. The breeding period of carp is concentrated in spring (February-June), reaching its peak in late spring and early summer, and the best temperature for spawning is about 25. In the south, the breeding season of carp generally begins in April and concentrates in May. In spring, females often lay a large number of eggs on plants or debris in shallow water, and the fertilized eggs hatch after 3-4 days, reaching sexual maturity in about the third year.

2. Carp reproduces once a year, and the eggs usually cannot be discharged all at one time, and need to be discharged many times, especially for larger individuals, it is many times, and even if multiple spawns are laid in an spawning cycle, it can only be counted as a breeding period. In general, carp will completely expel the eggs in their body within 2-3 times.

Summary. Crucian carp is an omnivorous fish that lives in freshwater, and in general, swims underwater, feeds and inhabits. When the air temperature and water temperature are high, they will also swim and forage in the middle and lower layers of the water.

Adult crucian carp is mainly a plant-based diet. Because the plant-based feed is abundant in the water body, there are many varieties and a wide range of food intake. The stems, leaves, buds and fruits of vascular aquatic plants are the favorite food of crucian carp, and crucian carp is also widely cultivated in wild and ponds in the Songhua River.

Crucian carp is very adaptable and can survive in both deep and shallow water, running water and still water. Even in highly alkaline waters with pH = 9, Lake Dari, with its high salinity, can still grow and reproduce.

Good afternoon, dear This question is up to me, typing takes a little time, and please be patient. Be sure to give some time, don't end your suppression consultation easily, thank you. When did a carp reproduce a crucian carp?

In the Yellowstone area, carp are breeding today, when will crucian carp breed.

Hello, dear. The breeding season of crucian carp is in the spring. 3-7 months is the breeding period of crucian carp, and April is the peak breeding period.

In the south, after mid-March, crucian carp begin to spawn when the water temperature rises to about 17 land, and the breeding activity is at its peak when the water temperature rises to 20-24, while in the north it does not spawn until April to May. Crucian carp spawn only when they are 1-2 years old. Crucian carp is one of the most common freshwater fish in China, living in major water systems outside the Qinghai-Tibet Liyu Plateau.

Is it Anhui Huangshi?

Sorry, I misremembered, haha. It is Huangshi, Hubei.

You Huangshi belongs to the south, so crucian carp will soon breed and spawn.

Because the plant-based feed is abundant in the water body, there are many varieties and a wide range of food intake. The stems, leaves, buds and fruits of vascular aquatic plants are the favorite food of crucian carp, and they are widely cultivated in wild and pond farms in Songhua River. Crucian carp is very adaptable and can survive in both deep and shallow water, running water and still water.

Even in the highly alkaline waters with pH = 9, Lake Dari, where the salt field modulus is high, can still grow and reproduce.

Huangshi, Hubei: I saw that the carp in the lake were breeding, and the crucian carp was fast.

Yes, because you also belong to the south, the crucian carp in our south will begin to multiply in large numbers when the water temperature is above 17°.

Breeding is at its peak when the water temperature is between 20°C and 24°C.

After sexual maturity, carp reproduce and spawn in the right season. In general, females can only reproduce once a year. If the eggs can be excreted all at once, the carp can only spawn once a year.

However, there are times when the eggs cannot be excreted all at once, especially when the mother is large and has a large number of eggs. At this point, they will release all the eggs in several batches. In this case, they can lay eggs two or three times a year.

Carp is a common fish that lives in freshwater. Females are ready to reproduce after they are sexually mature, and their age of sexual maturity is generally around 2 years old. After that, they will breed and lay eggs during the appropriate breeding season.

In general, females can only reproduce once a year. If the eggs can be excreted all at once, the carp can only spawn once a year. However, sometimes the eggs cannot be excreted at one time, and the carp need to spawn multiple times.

Especially when the carp is relatively large and the number of eggs is relatively large, the carp generally has to ovulate many times, and the eggs can be discharged within 2-3 times.

Carp breed in a suitable breeding season, when the water temperature is more suitable. Generally speaking, from February to March, the water temperature starts to rise, and the current also starts to flow, and the carp will start to reproduce at this time. Specifically, it is different for different regions.

In the southern region, the water temperature can rise to a suitable state for carp breeding in February, and carp can reproduce; In the north, it is generally not possible until March.

From this until June, it is basically the time for carp to breed. In late spring and early summer, carp reproduction is at its peak. In particular, when the water temperature is around 25 degrees Celsius and the current velocity is in meters per second, it is the most suitable time for carp breeding.
