Environmental requirements
Koi and goldfish, like the water temperature, water quality requirements are not strict, the temperature range of 2 ℃ ~ 30 ℃, but can not resist sudden changes in the water temperature, the temperature difference of more than 2 ℃ ~ 3 ℃ koi will be uncomfortable, the optimal temperature of the water for the 20 ℃ ~ 25 ℃; the need for sufficient oxygen, suitable for living in a slightly alkaline, hardness of the water environment of low hardness. The most suitable water temperature is 20℃～25℃; it needs sufficient oxygen and is suitable for living in slightly alkaline and low hardness water environment.
Second, dietary requirements
Koi are omnivorous fish, general mollusks, higher aquatic plant fragments, benthic animals to fine algae or synthetic granular bait can be eaten.
Three, species selection
You should choose the species that are healthy, free of injury, scaling and other diseases, and have a bright, colorful and well-defined body.
Fourth, stocking density
Fish pond density general stocking can refer to the density table of fish pond stocking Koi; water cluster box density of 60 cubic centimeters × 30 cubic centimeters × 15 cubic centimeters can be stocked with body length of 15 cm to 20 cm Koi 6 tails; 90 cubic centimeters × 30 cubic centimeters × 50 cubic centimeters can be stocked 8; 110 cubic centimeters × 30 cubic centimeters × 50 cubic centimeters can be stocked; 110 cubic centimeters × 30 cubic centimeters × 50 cubic centimeters can be stocked ×The density table of stocking Koi in fish pond
Fifth, bait feeding
Koi is omnivorous fish, it is best to feed synthetic pellets, bait, soybean cake, vegetable cake, breadcrumbs, fish worms, clams, crab meat, turnip, duckweed, etc. can be.
Six, four seasons management
Koi with the seasonal temperature changes, its management methods are different. In spring, the weather is still cold, the koi hibernation recovery, feeding from indoor to outdoor, but pay special attention to the sudden cooling, to cover the film in a timely manner, to maintain a stable water temperature; bait to plant-based bait, the amount of input from a small gradual increase in the amount of koi to facilitate digestion and absorption. In summer, when the weather is hot, we should cover the plastic shading net to prevent direct sunlight, so that the sunlight illuminance will be reduced from 8,000 to 12,000 lux to 5,500 to 5,800 lux as the most suitable. Autumn weather less rain and more sunny, the water temperature has dropped significantly, the most suitable for koi growth, can increase the proportion of animal (protein), such as silkworm pupae and so on. Increase the amount of feeding to promote fast growth. In winter, the weather is cold, when the temperature drops to 0 ℃, the koi will be transferred to the indoor pond wintering, indoor water temperature should be maintained at 2 ℃ ~ 10 ℃, pay attention to the focus is heat preservation, appropriate baiting, fat prevention and disease prevention, the period from November to March of the following year for the koi wintering period.
Seven, fish disease control
Common fish disease of koi mainly water mold, gill disease, enteritis disease, vertical scale disease and so on.
1. Water mold disease (skin mold disease, white disease) Symptoms The sick fish body surface parasitic with gray and white cotton wool hairless mycelium. Prevention and control methods ① malachite green 0.2ppm ~ 0.4ppm immersion; ② formalin 0.5ppm immersion; ③ salt 400ppm ~ 500ppm and sodium bicarbonate 400ppm ~ 500ppm formulated into a combination of the diseased fish with a small pool of centralized application of drugs.
2. Gill rot Symptoms: The fish is slow to move, the body color and the head is black, in severe cases, the gill filaments are rotten, and the gill cover has a small transparent window. Preventive methods ① bleach 1ppm immersion; ② furacilin 1.5ppm ~ 2ppm immersion; ③ erythromycin 0.3ppm immersion; ④ copper sulphate 0.5ppm ~ 0.7ppm sprinkling.
3. Intestinal inflammation disease Symptoms The body color is black, *** red and swollen, the abdomen is enlarged, and there is yellow mucus spillage in the abdominal cavity. Prevention and treatment methods ① furazolidone 0.1ppm ~ 0.7ppm immersion, with hygromycin bait feeding; ② furazolidone 1 grams ~ 2 grams / 100 kilograms, 3 days of continuous oral; ③ a small amount of garlic mashed bait feeding, feeding for 3 days.
4. Vertical scale disease (scale disease, loose scale disease) Symptoms Rough body surface of the fish, the whole body scales up like a pine ball, the base of the scales edema, the accumulation of exudate. Prevention and treatment ①Furacilinum 1ppm. ② feed in 0.5% salt water, stop eating for 2 days, feed with sulfadiazine 0.6g per tail per day. ③Saline 2% water solution for 10 minutes. ④ Erythromycin 2.0 ppm ~ 2.5 ppm immersion 30 minutes ~ 50 minutes.
What do you feed the red carp at home to her? Not fish feed
If it is a small surface culture, you can go to the flower and fish market to buy special bait, not easy to muddy water, I often use koi 1 catty bait, about 8-10 yuan, large particles, dark brown better. If you don't feed fish feed, dry steamed bread crumbs, dry bread crumbs, shrimp skin, green vegetable leaves are fine.
What does the carp eat
Its food composition changes as it grows, the young fish to eat plankton as the main body length of 20 millimeters after the shift to eat small benthic invertebrates; adult fish to eat benthic animals as the main food, but also eat water plants and algae, is omnivorous.
What do red carp eat?
The red carp is omnivorous, has a wide range of food, and does not require high living conditions. It mainly eats rotifers and small branchiopods
How does the red carp chew its food
The carp has only tiny teeth in its mouth!
Its teeth have no chewing function!
These tiny teeth are used to hold food and prevent it from slipping out!
Carp eat what food meat good long big
Fish meat raw materials introduction to the fish are many kinds of fish, the main food talk about water fish, including carp, grass carp, crucian carp, Mandarin fish, etc., saltwater fish, including yellow croaker, scallop, flatfish, etc.. They are all characterized by tender and tasty meat, rich in nutrients, and are a good source of some vitamins and minerals.
Nutritional analysis
Fish is delicious, whether it is meat or soup, are fresh and tasty, appetizing, is a favorite food in the daily diet. There are many types of fish, roughly divided into two categories of saltwater fish and freshwater fish. But whether it is saltwater fish or freshwater fish, the nutrients it contains are generally the same, the difference is only the amount of various nutrients. Fish nutritional value is very high, it was found that children often eat fish, its growth and development is faster, the development of intelligence is also better, and often eat fish, people's body is more robust, life expectancy is also relatively long, the mystery lies in the following nutritional characteristics of fish:
1. Fish contains folic acid, vitamin b2, vitamin b12 and other vitamins, there is a nourishing and healthy stomach, diuretic, swelling, through the breast, Clearing heat and detoxification, stop coughing down the efficacy of a variety of edema, swelling, bloating, oliguria, jaundice, breast milk are effective;
2. consumption of fish on the pregnant woman's fetal restlessness, gestational edema has a very good therapeutic effect;
3. Fish is rich in magnesium, has a very good protective effect on the cardiovascular system, is conducive to the prevention of hypertension, myocardial infarction and other cardiovascular diseases;
4. Fish is rich in vitamin A, iron, calcium, phosphorus, etc., often eat fish and liver tonic blood, skin and hair effects.
5. Rich in complete protein. Fish contains a large amount of protein, such as yellowtail 17.6%, 18.1%, mackerel 21.4%, silver carp 18.6%, carp 17.3%, crucian carp 13%. The proteins contained in fish are complete proteins, and the amount and ratio of essential amino acids contained in proteins are most suitable for human needs, and easily digested and absorbed by the human body.
6. The fat content is low, and mostly unsaturated fatty acids. Fish fat content is generally low, most only 1% - 4%, such as yellowtail with 0.8%, scallop with 3.8%, mackerel with 4%, silver carp with 4.3%, carp with 5% crucian carp with 1.1% bighead carp (fathead minnow) only 0.9%, cuttlefish only 0.7%. Fish fat is mostly composed of unsaturated fatty acids, unsaturated fatty acids have a longer carbon chain, has the effect of reducing cholesterol.
7. Higher content of inorganic salts and vitamins. Marine fish and freshwater fish are rich in sulfur, but also contains phosphorus, calcium, iron and other inorganic salts. Fish also contains a large amount of vitamin A, vitamin D, vitamin B1, niacin. These are nutrients that the human body needs.
In addition, the muscle fiber of fish meat is relatively short, the protein tissue structure is loose, the water content is more, therefore, the meat is more tender, and livestock meat compared to eat more feel soft and tender, but also more easily digested and absorbed. Therefore, it can be seen, fish has a high protein, low fat, vitamin, mineral content, good taste, easy to digest and absorb the advantages.
Suitable for the crowd
The general population can eat
1. For a variety of edema, edema, bloating, oliguria, jaundice, breast milk can not be eaten;
2. Chronic disease should not eat more.
We all know that the body is developing young children to eat more fish, but what children eat fish, but should pay attention to speak.
Recently, a study of three Asian families with children between the ages of 15 months and 2 years old, who ate fish porridge every day, found that mercury levels in these children were five times higher than normal.
According to the Medical Journal of Australia, Dr. Stephen Cowie Yuen, a doctor at Sydney's Western District Public **** Health Service, said that it is important for children to eat both the right kind of fish and the right amount. Even relatively low levels of mercury can affect normal pediatric development. Dr. Lisa Szabo, chief scientist at the New South Wales Food Authority in Australia, said young parents should be wary of seven types of fish - shark, swordfish, sailfish, marlin, tilapia, squareheads, and catfish. In addition to their relatively large size, these fish are predators with longer life cycles and higher levels of mercury in their bodies than other fish. In this regard, the U.S. Food and Drug Administration (FDA) has long warned against giving children large predatory fish including sharks, sailfish, golden mackerel, and squareheads because of their high mercury content.
