Brocade carp is a kind of high-grade ornamental fish that is popular in the world today. it has a strong physique, bright colors, changeable patterns, heroic swimming posture, living gemstones in the water, and the laudatory name of works of art that can swim in groups. It is easy to raise and adapt to the water temperature. It can live in a water temperature environment of 5: 30 ℃. Let's take a look at how the brocade carp grow quickly.

What kind of feed does brocade carp have?

1. Animal feed: animal feed is one of the most favorite and nutritious feeds for koi. There are many kinds of animal feed, such as fish insects (red worms, water fleas), cyclopsylla, paramecium (ash water), chironomid larvae, water earthworms and so on.

2. Plant feed: koi feed is the most ideal animal feed, but due to the lack of animal feed for a variety of reasons, plant feed can be used as an emergency or life-sustaining auxiliary feed, such as Wuping, aquatic plants and so on.

3. Synthetic feed: the synthetic feed of koi is artificially arranged according to the growth needs of koi. It has a full range of nutrients and meets the needs of the growth and development of koi. The main ingredients include protein, sugar, fat, inorganic salts and vitamins.

The selection and purchase method of brocade carp

1. Health: no matter what kind of fish you buy, you should choose those that are flexible in swimming, active in eating, well-proportioned and strong, with wide shoulders, thick mouth and strong tail handle. Among other things, as long as you are in good health, the process of raising will be able to reduce the troubles of disease.

Feeding method of brocade carp

1. Weight gain: the water temperature should be fed no more than 2 times a day when the water temperature is above 30 degrees Celsius. The water body should not be fed more than 2 times a day due to direct sunlight. If the water temperature is 20-30 degrees Celsius, 2-4 times a day, it is recommended that you do not use body-increasing materials.

2. Color poplar: the water temperature should be fed no more than twice a day when the water temperature is above 30 degrees. The water body should prevent the water temperature from rising due to direct sunlight. When the water temperature is 20 degrees 30 degrees, 2 or 4 times a day, it is recommended that poplar materials should not be used when the water temperature is below 20 degrees.

3. Breeding: the water temperature of juvenile fish is not more than 4 times a day when the water temperature is above 30 degrees, and that of adult fish is not more than 2 times a day. The water body should prevent the water temperature from rising due to direct sunlight. The water temperature is 20 degrees 30 degrees and 2 times a day, and the water temperature is 15 degrees 20 degrees twice a day.

4. Germ: the water temperature of juvenile fish is above 30 degrees not more than 4 times a day, and that of adult fish is not more than 2 times a day. The water body should prevent the water temperature from rising due to direct sunlight. The water temperature is 20 degrees 30 degrees and 2 times a day, and the water temperature is 15 degrees 20 degrees twice a day.

5. staple food: the water temperature is above 30 degrees not more than 4 times a day for young fish and not more than 2 times a day for adult fish. The water body should prevent the water temperature from rising due to direct sunlight. The water temperature is 20 degrees 30 degrees and 2 times a day, and the water temperature is 15 degrees 20 degrees twice a day.

How do koi grow fast?

1. Water quality management: koi is not strict on water temperature and water quality, so it is suitable to live in a slightly alkaline and low hardness water quality environment. However, as the saying goes, "raise water first", so do not underestimate the water quality. You should know that most diseases of koi are caused by poor water quality.

2. Water temperature management: the range of water temperature for koi is 2: 30 ℃, and the most suitable water temperature for life is 20: 25 ℃. In this temperature, koi swim actively, have a strong appetite, have a strong physique and have bright colors.

3. Breeding density: koi should pay attention to the density when raising koi. Generally, 6 koi with a length of 15 cm, 8 carps with a length of 90 × 30 × 50 and 10 carps with a length of 110 × 30 × 50 cm can be raised in an aquarium with a length of 60 × 30 × 15 cm.

4. Feed feeding: koi is similar to goldfish in feeding, and can be fed twice a day. Depending on the increase or decrease of temperature in different seasons of each year, fish and insects, pellet feed, small earthworms and other bait can generally be fed, but should they be fed too much? generally, 80% can be full.

5. Prevention and treatment of fish diseases: common diseases of koi include water mildew, Gill rot, enteritis, vertical scale disease and so on. Attention should be paid to the administration of corresponding drugs to improve the disease. Although brocade carp disease is inevitable, it is still recommended to do a good job in the prevention of brocade carp disease.

6. Management of the four seasons

① spring: the weather is warm and cold again, koi begins to recover from hibernation, should be transferred from indoor to outdoor, but should pay attention to sudden cooling, timely cover film, keep the water temperature stable. The bait was mainly plant bait, and the amount of bait increased gradually.

② summer: the weather is hot and hot, so it is most suitable to cover with plastic shading net to prevent direct sunlight, so that the sunshine intensity can be reduced from 8000 lux to 5500mm 5800 lux.

③ autumn: the weather is less rainy and more sunny, and the water temperature decreases obviously, which is the most suitable for the growth of brocade carp, which can increase the proportion of animal protein, such as silkworm pupa. Increase the amount of investment to promote fast growth.

④ winter: the weather is relatively cold, when the temperature drops to 0 ℃, the koi should be transferred to the indoor fish pond in time to overwinter, and the indoor water temperature should be kept at 2: 10 ℃. Proper bait should be used to keep fat and prevent disease.

Disease prevention and control techniques of koi

1. Skin mildew of brocade carp

[symptoms] the fish has a layer of white hair on its body. if left untreated, the fish will gradually weaken and die when the bacteria invade the body. When parasitic in the Gill, it forms Gill mildew, which often causes explosive death.

[prevention and treatment] ① was washed with 1.5-2.5% salt water, removed the hair, then smeared with 2% red potion, and then bathed with fish oxytetracycline. ② smeared the wound and the attachment of water mold with a malachite green aqueous solution of 0.1% concentration. ③ soaked the fish in malachite green aqueous solution tried by 1RU 15000 for 3 minutes and 5 minutes. ④ soaked the fish in 10 mg / kg potassium permanganate solution for half an hour.

2. Enteritis of Carp

[symptoms] the anus is red and swollen, the intestines are congested and inflamed, when it is severe, the fin base is congested, erythema appears in the abdomen, ascites flows out during laparotomy, the whole intestine is red or purple.

[prevention and treatment] ① was sprinkled all over the pool with 1 mg of bleach per kilogram. The water depth of ② is 10 mm per hectare and the whole pond is sprinkled with 225-375kg of quicklime. ③ 1 gram of sulfonamidine for every 10 kg of fish is used as bait. ④ use 50 grams of garlic for every 10 kilograms of fish as bait, once a day for three consecutive days. ⑤ uses 50 grams of dried Camellia sinensis for every 10 kilograms of fish as bait, once a day for three consecutive days.

3. Erect scale disease of Carp

[symptoms] the body surface of the diseased fish is rough, the scales are erect, and the appearance is pine ball. In severe cases, exophthalmos, shortness of breath, back overturn, and even death. Scale sac edema, its internal accumulation of transparent or bloody exudate, if a little pressure on the scale, liquid will be ejected from the scale. The diseased fish sank to the bottom or lost its balance, raised its abdomen and died of exhaustion.

[prevention] ① prevents fish from injury. ② parent fish spawning ponds should be dry in winter and disinfected with quicklime or bleach. ③ added 5% crude chlortetracycline or oxytetracycline to the feed. ④ was taken orally with vitamin E. Every 10 kg of fish body weight was given 0.3-0.6 g per day for a long time, and increased to 0.6-0.9 g (10-10 kg for 15 days) as an adjuvant.

4. White skin disease of brocade carp

[symptoms] the white skin disease of brocade carp is caused by Trichoderma. The skin from the back of the dorsal fin to the base of the caudal fin is white and foggy, and the scales are rough and mucus-free. When the sick fish are killed, the head is often down and the caudal fin is upside down.

[prevention] be careful when operating ① to prevent fish injury. ② chlortetracycline 12.5mg / kg or oxytetracycline 25mg / kg soak the fish for 30 minutes. ③ sprinkles with bleach 1 mg / kg or gallnut 2mg / kg throughout the pool.
