1. koi fish was put into the new koi fish aquarium too fast.
Even with the best nitrifying bacteria, koi fish won't be released until the third day.
Letting koi fish go prematurely will only do more harm than good.
Step 2 eat too much
Remember: feed the right amount, eight points is enough.
Generally only once a day, remember not to feed more than twice a day.
Because the novice has not fully mastered the water quality, and the influence of excrement and food residue on the water quality is not clear.
So it is enough to feed once a day, not too much. Don't overfeed koi fish for fear of not having enough to eat.
After all, the probability of starving fish in koi fish is too low. Overfeeding koi fish will only kill them.
filter
Remember: filter well and don't clean frequently.
The continuous operation of the filter is very important, and the nitrifying bacteria population on the filter material is the biggest guarantee to ensure the fish health in koi fish.
Replacing all the filter materials with new ones, or cleaning them too cleanly, is a death warrant for koi fish. The correct way is to change water.
Separate the time for cleaning the filter materials, and clean the filter materials in batches or just casually. If the fish in koi fish are in the state after cleaning the filter,
Please stop feeding for two or three days immediately and supplement nitrifying bacteria immediately.
Water quality circulation formula: ammonia (NH3+) or ammonium (NH4+)->; Nitrite (NO2-)->; Nitrate
-& gt； Nitrogen (N2)&; Oxygen (O2) Note:-> Nitrifying bacteria->; Denitrifying bacteria action
This is the most basic biological change in fish tanks in koi fish. Ammonium or ammonia in excrement (with different toxicity due to different ph values).
Nitrate (NO3-) is transformed into nitrite (NO2-) by nitrifying bacteria, and its toxicity is low.
Through the transformation of anaerobic bacteria, it also becomes nitrogen and is discharged into the air. High concentrations of ammonia and nitrite are usually the cause of koi fish's illness or death.
Nitrate may be the cause of fish growth retardation and algae overgrowth in koi fish.
The above simple formula can help you to establish the concept of fish tank environmental protection in koi fish. From these formulas,
It explains why there is too much feeding without proper water change (too many pollutants for nitrifying bacteria to clean up toxins).
And cleaning the filter material too clean (nitrifying bacteria are removed from the filter material, and there is no nitrifying bacteria to clean the toxin), which will make the fish in koi fish sick and die.
4. Wrong choice of fish tank in koi fish.
Note that the smaller the fish tank in koi fish, the more difficult it is to control the water quality, and the greater the water capacity of the fish tank in koi fish, the less difficult it is to control the waste concentration.
In addition, many novices buy small koi fish fish tanks, and koi fish fish tanks have filter tanks behind them, so it is difficult to clean them thoroughly. If you want to clean them up,
There may be too much water change, so this koi fish fish tank is not recommended for beginners to try.
5. Do not add medicine, change water and clean the filter.
These three kinds of chaos are usually the most common mistakes made by novices. If the three kinds of chaos happen at the same time, the probability of all koi fish's deaths is about 90%, especially those who raise little koi fish.
When there is a problem with fish in koi fish, please stop feeding, then change some water, add better quality nitrifying bacteria, and immediately ask an expert to help you judge before deciding how to deal with it.
6. Don't change the water
Remember: change the water regularly, and the amount of water is moderate.
Keep koi fish for too long without changing the water, and be careful not to change the water too much.
The frequency of changing water varies with the species and feeding amount of koi fish, ranging from once a month to once a week, and novices can choose to change it every two weeks.
The water exchange rate should be within 1/3, and the water adding speed should not be too fast, at least within 20~30 minutes.
Because the change of pH value of water has a great influence on koi fish, don't forget to add water stabilizer before adding water.
It is too late to add water.
To sum up, make up a formula as follows:
Koi fish feeding remember: feeding the right amount, eight points is enough.
Koi fish remembers to change water: change water regularly, and the water quantity is moderate.
Remember the water quality formula: remember the basic changes by heart.
Koi fish filter remember: filter well, don't wash frequently.
Koi fish Fish Tank Remember: The smaller the tank, the harder it is.
Remember when koi fish enters the tank: Be careful when entering the tank against the current ... >>
Question 2: 1 How to make koi fish grow faster? There should be a large enough water body, that is, a large pool or aquarium.
2. Feed several times a day; Food should be rich, such as granules, red worms, dry food, etc.
3. The temperature should be kept at 20-25 food intake.
4.*** Oxygen improves food digestion speed.
5. Filter well and keep a good environment.
6. It is related to the genes of fish. Usually monochromatic fish grow bigger, such as gold.
Question 3: Six Taboos on How to Raise Novice koi fish We summarized the most common mistakes that novices make when raising koi fish. These seemingly insignificant problems were the direct factors that led to koi fish's illness and death. 1. The best nitrifying bacteria were used when the new koi fish fish tank was put into koi fish prematurely, and it was not put into koi fish until the third day. It will only do harm to koi fish prematurely. 2. Overfeeding. Remember: feed the right amount, eight points, usually only once a day, remember not to feed more than twice a day. Because the novice has not fully grasped the water quality and the influence of excrement and food residue bait on the water quality, it is enough to feed once a day, and the feeding amount should not be too much. Don't overfeed koi fish for fear of not having enough to eat. After all, the probability of starving fish in koi fish is too low. Overfeeding koi fish will only kill them. 3. Filtering Remember: It is very important to filter well and clean the filter that does not run frequently or continuously. Nitrifying bacteria population on filter media is the biggest guarantee to ensure the health of koi fish. Replacing all the filter materials with new ones, or cleaning them too cleanly, is a death warrant for koi fish. The correct method is to separate the time of changing water and cleaning filter materials, and clean filter materials in batches or casually. If the fish in koi fish have problems after cleaning the filter, please stop feeding for two or three days immediately and add nitrifying bacteria immediately. Water quality circulation formula: ammonia (NH3+) or ammonium (NH4+)->; Nitrite (NO2-)->; Nitrate (NO3-)->; Nitrogen (N2)&; Oxygen (O2) Note:-> Nitrifying bacteria->; Denitrifying bacteria This is the most basic biological change in koi fish fish tanks. Ammonium or ammonia in excrement (with different toxicity due to different ph values) is converted into nitrite (NO2-) by nitrifying bacteria, and nitrate (NO3-) with lower toxicity is also converted into nitrogen by anaerobic bacteria and discharged into the air. Excessive concentration of ammonia and nitrite is often the cause of koi fish's illness or death, while nitrate may be the cause of koi fish's slow growth and algae overgrowth. The above simple formula can help you to establish the concept of fish tank environmental protection in koi fish. From these formulas, it is explained why excessive feeding without proper water change (too many pollutants and nitrifying bacteria can't clean toxins) and excessive cleaning of filter materials (nitrifying bacteria on filter materials are removed, and there is no nitrifying bacteria to clean toxins) will make koi fish sick and die. 4. Wrong choice of fish tank in koi fish Note that the smaller the fish tank in koi fish, the more difficult it is to control the water quality, and the greater the water capacity of the fish tank in koi fish, the less difficult it is to control the waste concentration. In addition, many novices buy a small koi fish fish tank, and koi fish fish tank has a filter tank behind it, which is difficult to clean thoroughly. If you want to clean it, you may change too much water. Therefore, novices are not recommended to try this koi fish fish tank. Adding medicine, changing water and washing the filter screen are usually the most common mistakes made by novices. If the three kinds of chaos happen at the same time, the probability of all koi fish's deaths is about 90%, especially those who raise little koi fish. When there is a problem with fish in koi fish, please stop feeding, then change some water, add better quality nitrifying bacteria, and immediately ask an expert to help you judge before deciding how to deal with it. 6. Don't change the water. Remember: change the water regularly, and the water should be moderate to raise koi fish. Do not change the water for too long. When changing water, be careful not to change too much water. The frequency of changing water varies with the species and feeding amount of koi fish, ranging from once a month to once a week, and novices can choose to change it every two weeks. The water exchange rate should be within 1/3, and the water adding speed should not be too fast, at least within 20~30 minutes. Because the change of pH value of water has a great influence on koi fish, don't forget to add water stabilizer before adding water, and it will be too late to add water. To sum up, add a formula as follows: koi fish Feed Fish Remember: Feed the right amount, and you can change the water in koi fish in eight minutes. Remember: change the water regularly, and the water quality formula is moderate. Remember: basic changes are in your heart. Koi fish Filter Remember: Filter well, and don't wash koi fish fish tank. Remember: the smaller the water tank, the harder it is. Remember: koi fish enters the tank with water, so be careful.
Question 4: How does koi fish raise 40 points and how does koi fish raise the selected fish?
Choosing fish is the key to raising koi fish. Buying small fish with the size of 10-20 cm has the highest success rate. When choosing fish, you should see whether the water is too muddy and whether there are a few rotten fish in school. If that's the case, you don't have to look at the fish in this pool. If this passes, you can see the koi fish you want quietly. Don't buy a short-headed, blunt, thin or bloated koi fish. Choose fish with symmetrical body shape, active swimming posture and bright eyes. After choosing the koi fish, remember to ask the store to aerate your fish. After taking the fish home, don't open the bag in a hurry. Put the whole bag with fish on the surface of the water for 45 minutes-1 hour, so that koi fish can gradually adapt to the temperature of the water. Then open the bag, let the fed water gradually mix with the water in the bag, and then put the fish.
How did koi fish raise and feed him?
When it comes to how to raise brocade fish, the first thing to look at is feeding. Koi fish is an omnivorous fish, eating a variety of foods, such as bread crumbs, plant fragments, earthworms, breadworms, rice, fruits and so on. Koi fish can be fed with 60% plant feed and 40% animal feed. Koi fish should feed it two or three times a day, and the feeding amount shall be subject to eating the feed within ten minutes each time. It is recommended to buy bulk spices (a mixed pellet feed with a brown smell).
How to improve the feeding density in koi fish?
Please refer to the density table of middle stocking fish ponds in koi fish for the general stocking situation of middle stocking fish ponds in koi fish. The density of the water cluster box is generally 60 cubic centimeters ×30 cubic centimeters × 15 cubic centimeters, and six koi fish with a body length of 15 centimeters to 20 centimeters can be stocked; 90 cubic centimeters ×3 0 cubic centimeters ×50 cubic centimeters can be stocked with 8 tails; 1 10 cubic centimeter× 30 cubic centimeter× 50 cubic centimeter can be stocked 10 tail. I hope you can buy your own koi fish fish tank according to your actual situation.
How much should koi fish eat?
It would be nice to keep a few in koi fish. According to Feng Shui, it is generally more appropriate to raise Kyubi no Youko. In China's traditional scholarship, the highest number of taking nine as yang has extremely lofty significance; There is a saying in Feng Shui that "three is infinite, six is infinite". Vulpix Dante means "good luck", and the five tails are red and white, which means "five blessings"; In addition, the sayings of "three sheep open Thailand" and "Shuanglong playing in the water" are also widely circulated. Therefore, koi fish is rich and geomantic, and it is best to raise koi fish three, six, five, nine and two tails at home.
How to manage the four seasons in koi fish?
Koi fish's aquaculture should also pay attention to the changes of the four seasons. In spring, koi fish began to recover from hibernation, and the feeding was transferred from indoor to outdoor, but special attention should be paid to the sudden cooling, covering the film in time to keep the water temperature stable; Plant bait is the main food, and the dosage is gradually increased from less. When the weather is hot in summer, plastic sunshade net should be covered to prevent direct sunlight. Autumn weather is less rainy and sunny, and the water temperature drops obviously. It is most suitable for koi fish to grow, and can increase the proportion of animal protein, such as silkworm chrysalis. Increase investment and promote rapid growth. In winter, the weather is cold. When the temperature drops to 0℃, koi fish should be moved to an indoor fish pond for wintering, and the indoor water temperature should be kept at 2℃ ~ 10℃. Pay attention to keep warm, feed properly and prevent diseases. The wintering period in koi fish is 1 1 to March of the following year.
Question 5: How to raise koi fish in fish ponds and koi fish in outdoor fish ponds in four seasons, and how to raise koi fish.
1. Is koi fish easy to raise?
Water temperature. Koi fish, like goldfish, has no strict requirements on water temperature and quality. It is a wide-temperature fish, and its adaptive temperature range is 2~30 degrees Celsius. However, although koi fish has strong adaptability to the environment, it has the weakness of being unable to resist the sudden change of water temperature.
Feeding. Just feed it 1 time every day, and it's 80% full. Koi fish is not very strict about bait. Artificial granular bait, such as bread crumbs, Daphnia, earthworm, live snail, clam, turnip and duckweed, can be fed. But to ensure the freshness of the bait, you can't feed the spoiled ones.
Change water. If there is no filter, you should suck out fish manure on time every day, and then suck out the same amount of trapped water (trapped for three days). In this way, only a little water needs to be changed, so that the water can be kept clean and oxygen can be injected. Water can be changed in large quantities for more than one week (or when water is mixed), that is, 3/ 1 water can be changed. Before changing the water, put the trapped water next to the fish tank several hours in advance, so as to ensure that the newly changed water and the water in the fish tank keep the same temperature and the fish will not get excited.
Second, how to raise koi fish?
1. How to raise koi fish in an outdoor fish pond?
The newly-built cement pool should be washed with alkali before use. Otherwise, it is not suitable for fish to survive. The method of dealkalization is to fill the pond with 0.25% phosphoric acid solution, soak it for 1 ~ 2 days, then rinse the pond wall with clean water, and then soak it in dark green water for about 10 days. Only when moss grows on the wall of the pond can it be tried out and put into koi fish after it is confirmed to be safe.
When the fry grow to 10 ~ 20cm, they can be put into the fish pond for feeding.
Koi fish is a temperature-changing animal, and its physiological activities are restricted by seasonal water temperature changes.
Spring. In early spring, cover the fish pond with a film to keep the water temperature stable. In early spring, koi fish woke up from hibernation and was weak. Feed should be gradually increased from a small amount, and some digestible plant feed should be used to restore her physique.
summer The high water temperature in summer is not conducive to the normal growth of koi fish. Therefore, it is advisable to cover fish ponds with sunshade nets. Otherwise, under the scorching sun, the water temperature in fish ponds will rise rapidly, leading to the proliferation of phytoplankton and green algae, and the water quality will be turbid, which will affect the survival of koi fish.
Autumn. Autumn is the most suitable season for fish growth, so you can put more bait appropriately to increase the proportion of animal protein.
winter In winter, the air temperature and water temperature decrease obviously, so it is best to move the koi fish indoors to keep the water temperature within the range of 0℃~ 10℃. The emphasis is on heat preservation and proper feeding. During the wintering period, the work of changing water, adding water and removing dirt should be reduced as much as possible, so as to reduce the energy consumption of fish during the wintering period and ensure the safe wintering in koi fish.
Step 2: Skills
1) Variety collocation. Mostly koi fish with bright colors, supplemented by dark, shiny and elegant ones. When outdoor fish ponds are raised, they are generally matched with red and white, Dazheng tricolor, Showa tricolor, gold or platinum, autumn water and light yellow.
2) density of fish ponds. For general stocking of fish ponds, please refer to the koi fish density table for stocking fish ponds; Generally, a fish pond with a water depth of 30 cm and a square meter can keep about 15 fish.
3. How many are there in koi fish?
Raising feng shui koi fish, the quantity is extremely important. General singular; In fact, if the tank is big enough, the most popular way is to use nine pieces. Because our country's tradition regards nine as the highest number of yang, it has extremely noble meaning. However, in Feng Shui, there is also a saying that "three is infinite and six is infinite". Six Dan Ding stands for "Good luck is better than New Year" and five red and white ones stand for "five blessings". When it comes to "three sheep open Thailand", the saying of "Shuanglong playing in the water" is also widely circulated. 3, 6, 5, 9 and 2 are auspicious numbers to consolidate the prosperity of koi fish.
Question 6: How to raise a good family in koi fish? The first is the selection of koi fish, which is what we often say about how to choose a good koi fish. Of course, we don't have to cultivate the scales of giant carp, so as long as healthy fish have no other symptoms such as trauma and bleeding, are in good shape, have no genetic mutations such as head tilt and body bending, and are pure in color, that is, bright and thick in color, fish lines can form individual objects with certain artistic patterns. Actually, it's that simple.
The second thing is the choice and configuration of the aquarium: different specifications of the aquarium should be selected according to the conditions at home, but it should be noted that since koi fish is a large ornamental fish, the aquarium should not be too small, and the minimum water capacity should generally reach 60kg. Also, Kim likes to travel with a group, which consumes a lot of oxygen. It is best to have a certain number of oxygen pumps and filtering equipment to ensure the cleanliness of the fish tank and sufficient dissolved oxygen in the water. Another point is that we breed koi fish for my daily appreciation, so it is better to install lighting equipment in the aquarium. Most of us choose metal halide lamps.
The third thing to pay attention to is feeding koi fish: to put it bluntly, it is the choice of feed bait for koi fish and koi fish several times a day. As we all know, koi fish is an omnivorous fish, eating both vegetarian and meat. Koi fish's food: our common vegetables and fruits, Chinese cabbage, carrots, bananas, watermelons, bread, rice and so on. Bait, such as Daphnia, earthworm, loach, meat, shrimp, etc. , must be disinfected.
Generally, the amount we feed is 70% to 80% full, otherwise it will cause indigestion of fish, which may be koi fish's disease-enteritis, which will also destroy the water quality. Pay attention to regular and quantitative feeding to ensure the quality of fresh water. Most fish friends feed 1-2 times a day, once in the morning and once in the evening. It is better to feed in the morning than at night. In case of showers, cooling and other weather conditions, you should feed less or not.
The fourth thing is to pay attention to water quality and water temperature: although koi fish has low requirements for water quality, it is easy to get sick if it fails to meet the requirements of koi fish. The pH value of water quality needed in koi fish is preferably around 7.4. The water temperature can survive at 2-30℃, but it is best to live in low hardness 15℃-25℃ water. Fish culture in koi fish needs clean water and fresh fish, and maintaining the water quality of fish in koi fish is the first condition. Cleaning should be done almost every day in summer, and the time can be extended in other seasons. Cleaning is mainly to remove koi fish's excrement and leftover food in the fish tank, and then replace it with clean water.
Question 7: How to raise koi fish? Koi fish's geomantic omen keeps a vibrant koi fish, which has a good effect on improving geomantic omen. Koi fish has always been regarded as a fish with aura, which can make the family fortune flourish. Therefore, the biggest function of placing Feng Shui fish in koi fish is to increase wealth and ward off evil spirits. Whether in the office or at home, if you want to set up a feng shui fish tank, the first step must be to find the right location. Only by putting the fish tank in the right position can it be promoted to the realm of transshipment, not just a single effect of beautifying the environment. But the bright financial position at home is generally in the diagonal position. No matter where you open the door, the diagonal line after opening the door is generally considered as a bright financial position in the house. When the fish tank is placed here, you can see it as soon as you open the door. It is quite eye-catching visually and can also play a role in urging money. The best number of fish culture in koi fish is nine (main longevity, main longevity), but some fish tanks are too small to keep as many as nine, so you can keep three or six, because three represents endless meaning (main longevity) and six represents endless meaning; Koi fish can't have black spots on his head. If there are black spots, he will be defeated. When a person and a family are safe and happy, it is even more taboo to bring such fish in. Even if we don't talk about feng shui, you can try to stare at a fish with black spots on its head, and you will feel uncomfortable. This is the role of fierce anger. The five elements belong to the golden zodiac in koi fish: in the zodiac, the birthdays of rabbits and chickens belong to gold, while metal means that people with metal faces have a dull life because of this meaning, but they also have less money because of this meaning. Therefore, in the choice of koi fish, koi fish is the first choice to increase wealth and receive happiness. Water Zodiac: In the zodiac, the birth of rats and pigs belongs to water, and water belongs to wisdom. Therefore, people who belong to water have a smooth life because of wisdom and a prosperous fortune because of water, but if they are too prosperous, they will ask for trouble. Therefore, the choice of koi fish, a feng shui fish, is mainly based on health and harmony, and the wealth is prosperous. Belonging to the wooden zodiac: Tiger is the most special of the twelve zodiac signs, and there is only one that belongs to wood, and wood belongs to benevolence, which is the first of the ten virtues. In ancient times, it was connected with the king of a country for benevolence. Therefore, people who belong to wood have the life of an emperor and the most prosperous wealth. However, the extremes meet, and the water overflows when it is full. Therefore, the choice of koi fish is mainly based on adding blessings, not windfall. Fire Zodiac: In the zodiac, the birthdays of snakes, horses and monkeys belong to fire, and fire belongs to ceremony. People who belong to the fire sign have many successful careers and are prone to trouble and suffocation. Therefore, we should choose koi fish with black as the main color to add happiness to ward off evil spirits. Belonging to the earth zodiac: in the zodiac, cattle, dragons, sheep and dogs are born of the earth, while the earth belongs to faith, and faith is the basis of honesty. Because of faith, the earth belongs to the nobles, and because of faith, most of them are late bloomers. Therefore, in the choice of koi fish, wealth is the first choice.
Question 8: How to raise water, disinfect, empty the jar and feed the newly bought koi fish once a day? It's simple.
Family rearing should master the following points:
1. Selection and configuration of aquarium
Aquariums of different specifications should be selected according to family conditions. However, due to the different living habits of koi fish and goldfish, the aquarium should not be too small, and the general water capacity should not be less than 60kg. Koi fish is large, so it needs to be enlarged properly, and its water capacity is not less than 200kg. Due to the large amount of activities and strong oxygen consumption in koi fish, the aquarium should be equipped with water filters and oxygen pumps to ensure sufficient oxygen in the water and clean water quality.
2. Bait and feeding method
Koi fish is an omnivorous fish, and animal bait and plant bait can be selected as koi fish bait, such as Daphnia, earthworm, rice, pasta and so on. But it's best to choose synthetic bait for ornamental fish. It is especially important to note that the feeding amount should not be too large. According to the daily viewing situation, only 70% to 80% is enough, otherwise it will cause adverse consequences, ranging from indigestion of fish to leftover food, which will damage the water quality. Don't feed in rainy days and at night.
3. Water quality and temperature
The feeding conditions in koi fish are different from those of goldfish. It needs high water quality, and neutral pH (PH7-7.4) is appropriate. Dirty water and white water in fish tanks are the most likely to cause fish death. In this case, measures should be taken in time or all the water should be replaced. The water temperature is generally kept between 15-25℃.
4. it is not suitable for polyculture
Koi fish is an omnivorous large ornamental fish, and all kinds of ornamental fish have different living habits, so it is best not to mix with other ornamental fish.
When raising koi fish, because everyone has different hobbies and different feeding conditions, the choice of koi fish should be based on personal hobbies, feeding level and family conditions. Pay attention to the following points when choosing:
One is to choose koi fish with a good figure. Because koi fish, like other fish, will have some genetic abnormalities, and some young fish will have congenital malformations, such as crooked head and bending. This kind of fish has no ornamental value and should be eliminated first.
Second, pay attention to whether the fish has obvious symptoms such as trauma and bleeding. Although some fish have no obvious traumatic diseases, they swim slowly, lose appetite, and often float on the water or stick to the corner of the fish tank, indicating that the internal organs of fish have other symptoms and should not be selected.
The third is to choose fish with obvious species characteristics, that is, to choose individuals with pure colors and artistic patterns.
Question 9: How to raise domestic carp is very useful, but it is a bit long. O (∩ _ ∩) O。 ...
Basically, it is almost enough to change one-fifth of the water every day ~ ~ ~ It is best to use sun-dried water, so that chlorine can be removed. Also, when changing water, the temperature difference in the cylinder should not exceed 5 degrees.
In spring (March-May in the solar calendar), the temperature rises gradually, generally between 10-20 degrees Celsius, and the water temperature environment is more suitable for the growth and reproduction of various pathogens, especially in April-May, which is the high incidence season of fish disease-barley yellow. When fry hatch in early spring, fish eggs are prone to water mold; Fish fry mainly suffer from fish diseases, such as rotifer, melon worm, dactylophora, trematode and fish lice. In spring, adult fish are prone to microbial fish diseases, such as viral hemorrhagic disease, enteritis, gill rot, printing disease, silver carp iodosporosis and so on.
In summer (June-August in the solar calendar), the temperature is generally between 26 and 28 degrees Celsius, and the incidence of fish is slightly less than that in spring. At this time, the fish species gradually grow up and their disease resistance is enhanced. Therefore, the fish diseases of ciliates and flagellates are gradually decreasing. In addition, according to the investigation, there are still microbial fish diseases in spring and summer, such as gill rot, hemorrhagic disease, erythroderma, enteritis, printing disease and so on. At this time, it is more common for parasites to have anchor head disease. In midsummer, high-yield ponds are often prone to flooding.
In autumn (Gregorian calendar 9- 10), the temperature drops gradually, generally between 23- 15 degrees Celsius, and the water temperature environment is basically similar to that in spring, especially in August-September, which is the season with high incidence of fish diseases-"Bailuxin". Summer flower fish mainly suffer from fish diseases such as rotifer, melon worm, giant salamander, trematode and fish lice.
In winter (Gregorian calendar1February-February), the temperature is low, generally between 3-6 degrees Celsius, and fish diseases rarely occur. Winter is the stocking period of fish species, and fish bodies are often scratched by pulling nets or transportation, and water mold can also occur; When the water temperature is high, it is possible to produce flagellates and cucurbits. When the water temperature of the overwintering fish is lower than 10℃, the temperature difference between the indoor air temperature and the water temperature is too large, which causes the fish to be frostbitten when floating due to lack of oxygen.
At present, with the change of temperature in spring, summer, autumn and winter, there are 12 kinds of common fish diseases, among which there are 7 kinds of parasitic diseases: trypanosomiasis, cucurbitaceae, giant salamander, anchovy, ichthyosis, silver carp iodosporosis and China herring disease; There are five kinds of microbial diseases: hemorrhagic disease (erythroderma), enteritis, gill rot, printing disease and water mold. As the saying goes, "fish farming is not bad, but it is dizzy with wealth." In fish farming, once fish diseases occur, the growth and development of fish will be affected, and some fish will die in severe cases. Therefore, we must attach importance to the prevention and treatment of fish diseases and actively implement the policy of "early prevention without disease and early treatment with disease"
You can judge the sex of a fish according to its size, shape, color, tail whiskers and fins.
There are many kinds of fish. When you cut open the belly of a fish, you see that it is a female fish full of eggs; A male fish has a milky "fish white" without fish eggs. But if you are given a live fish, how can you tell the sex of the fish?
Or from the appearance to identify.
Look at the fins of the fish. Misgurnus anguillicaudatus, the female pectoral fin is blunt, and the male pectoral fin is sharp. The pectoral fin of male carp is larger than that of female carp. Male [jiāng] has long dorsal fin and anal fin, and there are some yellow-green spots on the ventral fin, while female fish does not.
Look at the size and shape of this fish. Carp and crucian carp, females of the same age in the same place are always older than males. Tilapia (also known as African crucian carp), the female fish's reproductive hole and urine hole are separated, but the male fish are combined, so the female fish has one more hole than the male fish, but the individual is smaller. Female whitebait is transparent and has no scales, while male whitebait has a row of scales above the base of anal fin. The female anchovies are big and full, while the male anchovies are small and thin.
Look at the color of this fish. Many fish change color. Male fish used to have a gray-black back and a silvery-white abdomen. In the breeding season, its body will turn blue, red and yellow, colorful and beautiful. During the battle, the color of the male fighting fish will suddenly change, and in the breeding season, he will also put on a beautiful coat, which is golden yellow. This is the "wedding dress"; The female fighting fish is not so gorgeous, and some gray stripes are exposed on the brown body. Male goldfish will have some tiny sand-like particles on the gill cover and fins-"idolization", while female fish will not.
Raise water before raising fish.
For fish farmers, there are four kinds of water: first, fresh water, that is, tap water that has just been aired or well water that has been newly drilled. Although this kind of water is clean, it is very different from the environment in which fish live in nature. Because there is no nitrifying bacteria community in the water, fish excrement and scattered food residues are rotted ... >>
