Feeding and management of the fancy carps

* The column of the website concerning the feeding of fancy carps and prevention and cure of the fish diseases only represents private opinions and is for reference only *

It is recommended to sterilize the rearing ponds in spring and autumn.

Feeding and management in January

If controlling the water temperature to below 8℃, the carps will hibernate.
If moving the carps to other place, pay attention to the difference in temperature of the water of the rearing ponds.
Should the difference in temperature be up to over 5℃, it may endanger the life of carps.

Cold

Symptoms at the initial stage　Part of the fish body looks like being covered by a layer of white thin-film.
If conditions of the disease are worsened, the skin covered by the white thin-film will shed, result in anemia and turn white.
Symptoms at the advanced stage　Skin will ulcerate with the muscle revealed, and death will be caused out of the infection of bacteria and parasites for the second time.

Reason for cold and therapeutic methods　
Infections of ciliophora and white spot disease protozoan

• Sprinkle potassium permanganate 2k/t into the fishponds, and dip in for 3~5 days (drug for three times within one week.)
• Sprinkle formalin 25ml/t into the fishponds and dip in for 3~5 days (drug for three times within one week).
  Cold caused out of the too low-water temperature
• Elevate the water temperature to around 16℃ gradually (must not elevate the temperature by more than 5℃ at once.)
• Sprinkle salt 5kg/t and parazann D 100ml/t and dip in for one week.
• Sprinkle salt 5 kg/t and terramycin (OTC for fishery use in bulk) 50g/t and dip in for one week.

Feeding and management in March

The lengthy winter-sleep period ends finally, and enters into the active phase of carps.

Supply a tiny amount of feed (2~3 granules fish food for each fish) under the low water temperature once every other 2~3 days. Supplying excessive amount of feed for one time will result in indigestion and neopathy and thus further cause death of carps.

※Since carps have no stomach in their bodies and just wake up from the winter-sleep state, we shall supply a small amount of fish food at the very beginning so that the viscera within the fish bodies can become acclimated, and gradually increase the number of bait casting as time goes on.

Management concerning fish food

• Please throw away all the fish food purchased last year.
• When “the unhealthy status of carps” is reported, it is most likely that the overdue fish food is put into the ponds, if so, no wonder the carps will fall ill.
• All the fish food shall be put in the ponds within 3 months after unsealing.
• Even if the fish food vacuumized will also be oxidized gradually, therefore, there is often fresh fish food prepared in carp stores. You’d better purchase fish food from the store with a rapid purchasing speed of fish food when you want to purchase some.

Attentions for sterilization in spring and autumn

Why do the carps often die in spring and autumn? Why does the water of fishponds become muddy? Aquatic bacteria (filtration bacteria and malignant microorganisms and so on) are divided into the bacteria born in summer and that born in winter, which will have changes when the temperature is between 13℃~ 18℃, while the water temperature of 13℃~ 18℃ is usually the temperature of spring and autumn, when is the most dangerous period for the carps. Since the change period of water temperature is also the most active phase of the aquatic bacteria, the bacteria having the filtration function cannot function thus making the pool water become muddy, causing the massive propagation of bacteria and parasites and resulting in ciliophora disease and other carp diseases. Neglecting the aforesaid phenomenon will possibly lead to the death of carps. Various consultations concerning the carp diseases are mostly caused out of the negligence of the sterilization in spring and autumn.

Feeding and management in April

Rising of the water temperature makes the carps more joyful and more freely.

At this time more feeds and be supplied, but taking the weak constitution of the carps that just wake up from the state of winter-sleep into account, must not put in excessive feeds at once.

(When carp diseases happen and diseases are caused out of the damage of viscera, carps may die because of the untimely treatment.) April is the season for feeding fish in wild ponds.

Feeding carps in wild ponds
When feeding carps in wild ponds, cut and sterilize the fish food one week in advance.

※If the carp in the wild ponds falls ill, it cannot be cured even if it has been salvaged and we cannot help it, accordingly, we must formulate a considerate feeding solution.

For the sick carps, defer the implementation of feeding carps in the wild ponds.

The major purpose of feeding carps in the wild ponds is to enhance the constitution of the carps as soon as possible.

In addition, feeding carps in your own spring water for a long-term may restore the vivid luster of the carps again.

Carps may eat foods such as shrimps, river snail and algae in wild ponds and freely swim in the wide ponds, which enable the carps to grow healthily in the nature.

But this does not mean that all the carps are suitable to be fed in wild ponds.

The cases that the injured fish cannot be cured in time even if having been salvaged by fishnet thus finally resulting in death occur frequently.

In spite of the saying of “letting the lovely kids travel by themselves”, allowing the carps to swim for a while in the fishponds in autumn is only a kind of individual interest rather than an ideal method for feeding.

Feeding and management in May

When the water temperature rises to around 20℃, the appetite of carps will be greater and their activities will be more frequent. May is the spawning season for carps.

Gill disease

In spite of still being alive and frolic, carps turn their white bellies and die in the following day. Have you ever met with such problems? The main reason is that carps may have infected gill disease, the most awful disease for the golden carps.

Generally, a carp infected the gill disease (there is something wrong in the gill) may leave far away from the shoal, swim alone to the corner of the fishpond, put its mouth out the water surface and throw away the fish food. If you find the carps haven’t eaten any feed but the number of opening and closing their mouths (gill covers) is remarkably more than the other carps, they may have infected the gill disease.

If you find the carps haven’t eaten any feed but the number of opening and closing their mouths (gill covers) is remarkably more than the other carps, they may have infected the gill disease.

If you salvage the carps and observe their gill covers, you may find that part of the gill has turned white or been rotten, and the structure has been destroyed. The gill of healthy carps generally shows the comb-like shape and red color. When the bright red turns pink and then hoary, and when the entire gill structure has finally turned white, there is no other way but wait for death, as the gill of fish is like the lung of human beings that the destroyed structure will result in the difficult breath and death out of suffocation.

Since the gill disease bacteria have weak endurance against salt, therefore, we may put the salt water of 7% concentration into the vessels like basins and dip in for 10~20 seconds for sterilization. If the carps faint and lie flat, put them back into the fishponds immediately.

Strictly abide by the time specified.

Feeding and management in June

The season of plum rains is the season that brings the most difficulty in implementation of the management of the water quality.

Recently, it is said that the rains contain the “acid substances” ingredients, which, therefore, may cause some difficulty in feeding the golden carps. In order to prevent the acid rains from flowing into the fishponds, we may use the water quality stabilizer “Shuihuiyuan”

Aqualium clinic and erythema disease

The breeding season of the bacteria of aqualium clinic and erythema disease is in the seasons of spring and autumn when the water temperature has exceeded 12℃.
Having infected such pathogens, the carps may swim to the bottom of the fishpond and rub their bodies against the protuberance again and again. If observing the carps carefully, you may find that there are extremely small round parasites on the body surface of the fish, and the threadlike exiguous, long and narrow parasites among the squamas, which may accordingly destroy the body surface of the fish and make the fish infected all kinds of bacteria and pathogens, as well as lead to other complications.

Solutions

• Sprinkle mazotenn for fishery use (liquid 20 ％, 25ml/t, powder 0.5 g/t) into the fishponds and dip in for 3~5 days.
• Sprinkle the antiskinning agent as per the percentage of 1~2 g/t into the fishponds and dip in for 1 week ~ 10 days. It may be used together with mazotenn. Sterilization effect can be achieved by using the medicine for once only.

※ ※ Mazotenn may lustrate the fry of aqualium clinic, but is useless to the nit and adult of the aqualium clinic, so it shall be sprinkled for 3 times every other 10 days.
