How do you breed your own koi and how do you raise them after breeding?

When breeding home-bred koi, it is necessary to ensure that the water temperature is maintained. Strict attention should be paid to the management of the water tank, so that the close can carry out spawning and reproduction on its own.

Koi fish breed at a temperature of 18-35, and the suitable breeding temperature is about 22-30. Koi fish have a wide range of temperature tolerance, but they cannot adapt to sudden changes in water temperature. In general, the growth temperature range is 2-30, and the suitable growth temperature is 20-25.

The feed used for feeding koi includes natural bait such as greens, bean sprouts, melons and fruits, bread, cake crisps, steamed buns, etc.; Daphnia, earthworms, shrimps, bloodworms, crayfish and other animal bait; Synthetic bait such as fish meal, egg pupal meal, barley flour, bran, yeast meal, vitamins, green fodder, etc.

1. Choose broodstock: Koi breeding must first select a good broodstock, and we must choose a mature and robust koi, so that the offspring of breeding are also relatively good.

2. Broodstock tank: After preparing the broodstock, it needs to be put into the breeding tank, and the ratio of male to female is usually 1:3.

3. Breeding environment: In order to ensure that the fish can reproduce quickly, a good environment must be created, the temperature must be kept above 18, and oxygen should be charged at the same time.

4. Fish out the broodstock: After spawning and fertilization, the broodstock can be fished out so that it will not eat the eggs.

Koi are oviparous breeding fish that mate and breed when they reach breeding age, but the breeding koi should be over 60 cm. At the same time, the water temperature should be controlled at 18-25 degrees, pH value. According to the male and female 1:

2. Put it into the breeding tank, and feed it with high protein content and green fodder to promote ovarian development and reproduction.

Koi is an oviparous breeding fish, generally koi at the right breeding age, will mate on their own, mature male koi should reach 4 8 years old, female koi need to reach 5 years old or more is the best. At the same time, it is also necessary to pay attention to the breeding koi, which should average more than 60 cm.

During the breeding period of koi fish, the temperature of the feeding water needs to be raised to 18-25 degrees, and the pH of the water quality needs to be adjusted to. Then according to the ratio of male and female koi 1:2 into an independent breeding tank, oxygenated breeding.

During the intensive cultivation period of koi carp, the appetite is the most vigorous, and more feed with higher protein content should be fed, and green feed should also be fed, such as Chinese cabbage, spinach, duckweed, etc. to supplement vitamins and increase ovarian development.

The breeding season for koi is usually in the spring. Breeding can occur when the water temperature reaches 18 degrees or more to 35 degrees Celsius, and the optimal temperature is 22-30 degrees Celsius, and breeding can also be carried out in autumn.

When the water temperature is above 18 degrees, it is ready for reproduction. When carrying out natural reproduction, the fish nest should be prepared, usually using aquatic plants, pine leaves, palm flakes, nylon ropes, etc. sterilized with potassium permanganate solution, mainly to achieve uniform egging.

Fish fry cultivation When the fry hatch, they can swim sideways and start to splash egg yolk water, and after feeding for 3 days, they can be transferred to the fry pond for culture. Koi fish spawn 200,000 to 400,000 eggs each time, and hatch small fry in 4-7 days.

Choice of broodstock.

Broodstock for species should be selected more than 3 years old, with an individual of more than 60 cm, pure blood, excellent color quality, and strong physique.

The intensive cultivation of broodstock should begin in autumn, when the water temperature is about 25 degrees, and the appetite of the fish is vigorous, so the feed with a protein content of more than 38% should be selected and fed according to the proportion of 8% of the body weight;

Two to three times a day, at the same time, properly feed green feed, such as Chinese cabbage, spinach, duckweed, etc., to increase the supply of vitamins, and at the same time appropriately increase starch in the feed, such as rice, glutinous rice, etc., to increase the accumulation of fat.

Koi fish can reproduce, but domesticated koi fish need to meet certain conditions before they can reproduce.

First of all, if there is no hatchery pond, domestic koi fish need a larger fish Zhengna tank to reproduce.

Because koi fish are flicked and reproduced, they cannot reproduce if the tank is too small.

The second is that the age of the koi fish must be reached, and it generally takes more than 3 years to reproduce.

Finally, there is the breeding environment, and the breeder needs to adjust the water temperature, water quality, oxygen and light in order for them to reproduce.

1. Do koi fish breed Koi will breed, their breeding time is generally spring, as long as the water temperature reaches between 18-35, they can reproduce.

Koi fish are flicked and reproduced, so they need to have a large space, and if they are kept in a fish tank, the number of breeding times may be reduced a lot.

2. How can koi fish reproduce 1. Water temperature: Koi generally breed in spring, as long as the water temperature can reach 18-32, they can reproduce.

However, the most suitable temperature for them to breed is between 22-30, and it is recommended that the keeper should keep the water temperature at 25 to ensure that the water temperature is stable, which can effectively promote the breeding of koi.

2. Space: Koi carp shout jujube does not need a large space for breeding, because they are flicking tail breeding, if it is fish rock tank breeding, basically it is impossible to reproduce successfully.

In order for koi fish to reproduce, they need to be prepared with a large spawning and hatching tank.

If spawning and hatching tanks are not available, the keeper can prepare a larger tank for the koi to breed.

3. Water quality: Koi fish prefer weakly alkaline water, and it is best for the breeder to control the pH value between.

Especially in the early stages of reproduction, it is best to control the pH fluctuation not to exceed.

Ensuring that the water quality is fresh and stable can also promote the reproduction of koi fish.

Domestic koi do not breed on their own and need manual assistance.

Steps: 1. The breeding broodstock meets the requirements of age, appearance, and health. The best breeding period for Douba males is 3 to 6 years old; The best breeding period for females is around 4 to 10 years old.

When selecting breeding broodstock, the quality of juvenile fish can be improved by selecting fish with obvious varieties, good quality, and disease-free fish.

2. During the breeding process, select suitable temperature, pH, water quality and other conditions. When the water temperature is around 18 to 28 degrees Celsius and the pH level is 7 degrees Celsius, the broodstock with a 1 to 2 ratio of males to females can be placed in a pre-prepared breeding pond, preferably with a nest for self-spawning and reproduction. Keep an eye on the water temperature at all times, preferably below 18 degrees Celsius.

When the broodstock have laid their eggs, the eggs are fished out and placed in the hatchery to prevent them from being swallowed by the broodstock.

3. When the fry hatch out, it is best to put some water floating lotus in the hatchery pond for the fry to inhabit. There is no need to feed the fry for three or four days after they have hatched, as the yolk sac on the fry provides the nutrients needed by the fry. When the fry begin to forage on their own, feed some soybean milk, cooked egg yolk, etc. in the first balance week, and feed some bloodworms and earthworms after a week.

Breeding is complete.
