Have you heard about the domestication methods and domestication procedures of mandarin fish? Do you

Feeding method Mandarin fish fingerlings are fed bait fish on the day of stocking, the first 3 days are fed with a sufficient amount of live live bait fish, starting from the 4th day, gradually reduce the amount of feeding, in order to domesticate the mandarin fish to form a fast and accurate feeding response, this process takes about 7 days. After that, you can feed the live bait fish with some dead bait fish feeding, before feeding, start the water pump, make the water body in the cage form a water flow, and then a small amount of bait is tested, when the mandarin fish floats on the surface to eat, then a large amount of feeding, because the bait fish floats up and down with the current, can be eaten by the mandarin fish.

When breeding mandarin fish, it is necessary to cultivate the osmanthus fish, and to monitor the water quality, and to choose some scientific cultivation methods to improve the efficiency.

Cultivation of special pools.

Fish pond conditions and stocking area is not too large, generally in the hectare or so, above the water depth, good drainage and irrigation conditions, it is best to keep the flow of water frequently, stocking density in every 1000 square meters of stocking about 4500, before stocking we must thoroughly clear the pond, the use of lime water for disinfection, is conducive to improving the survival rate. Generally, the method of artificial feeding bait is adopted, and the mandarin fish has more requirements for bait, one to live, two to have no hard thorns, three to be palatable, and four to be timely.

There are many kinds of mandarin fish breeding technology, mainly pond construction, fry selection, stocking density, feed management, disease control, etc., only to do a good job in all aspects of technical management, in order to achieve more efficiency.

Surface selection. Mandarin fish can be farmed in waters suitable for raising silver carp and bighead carp in cages, such as rivers and reservoirs. Mandarin fish fingerlings into the box and stocking specifications.

The time of fingerlings into the box should be flexibly mastered according to the climatic conditions of each region, generally at the end of June and early July, and the size of the fingerlings is 8-10cm.

Mandarin fish, also known as osmanthus fish, seasonal fish, etc., belongs to the order Perch, Fin Family, and Mandarin Subfamily taxonomically. The body is fat and thick, the back is raised, the head is large, the snout is pointed, the scales on the body are small and rounded, the dorsal fin is long, the body is yellowish-green, and the body has brown stripes and patches of irregular size on the sides of the body. At present, there are many varieties of mandarin fish, such as Mandarin fish, Mandarin fish, Mandarin fish, etc., among which Mandarin fish has the characteristics of large individual size and fast growth rate, so the breeding is the most common and the breeding effect is the best.

Mandarin fish is a freshwater fish that prefers to inhabit clean still water or a slight flow of water, especially in lakes with abundant aquatic weeds, and is suitable for breeding in ponds.

Farms should have sufficient water sources and good water quality supply, and it is better to use non-polluted river water, lake water or large reservoir water. The pond area of adult mandarin fish breeding is 6-8 acres. The pond is too large to manage; If the pond is too small, the water quality is prone to deterioration, and in severe cases, it can cause hypoxia and often cause mandarin fish to become sick.

The water depth should be kept in meters. The bottom of the pool is kept with 15-20 cm of loamy silt. Newly excavated fish ponds without silt or sandy silt can be treated with an appropriate amount of organic fertilizer to enhance the buffering capacity of the water body and cultivate suitable water quality.

Old ponds with too much silt must be removed before stocking. There is a certain slope at the bottom of the pond, and there is a 30 cm fish trap at the low point, which is convenient for fishing. Pond stems should also be built into slopes to facilitate the cultivation of aquatic plants or aquatic vegetables at the edge of the pond.

Farmed mandarin fish ponds should be managed by special personnel, and the ponds should be inspected in the morning, noon and evening. In the morning, the pond patrol should observe whether the mandarin fish has a floating head, whether the bait is sufficient, if the mandarin fish floating head should be turned on in time to increase oxygen or fill with new water, if the bait is insufficient, it is necessary to increase the amount of feeding or the number of feeding. At noon, the pond should be inspected to observe the water color, transparency and weather conditions; If the water color is too strong, add water when the transparency is less than 40 cm, and add water or open an aerator in hot weather.

Patrol the pond in the evening to observe the feeding situation of the fish, and take measures in time if the fish are found to be inactive and the mandarin fish swim alone.

The pond for breeding mandarin fish requires a sandy bottom, less silt, an area of 3 5 acres, a water depth of meters, convenient drainage and irrigation, light water quality, no turbidity, no sewage inflow, and a small amount of fish pond with submerged aquatic weeds.

I don't know much about it, because this fish is relatively new to me, but I can look up some farming techniques on the Internet.

Mandarin fish, commonly known as cinnamon, is a special freshwater fish in China, which is delicious in taste, high in protein content and rich in nutrition, so it is widely loved by consumers. In addition, mandarin fish grows fast, high yield, economic value is greater, at present, in addition to the Qinghai-Tibet Plateau, mandarin fish is produced in large rivers, river systems and lakes in various places, and the aquaculture distribution is very extensive. So how to breed mandarin fish well?

Let's find out.

1. Pond selection.

The main pond for mandarin fish requires the selection of newly opened ponds with leeward and sunny conditions, loamy sand* substrate, and less or no silt. The bottom of the pool should be flat, slightly inclined to the drainage outlet, the water depth is meters, the irrigation and drainage system is perfect, the water source is sufficient, fresh, pollution-free, and the water quality is good.

2. Clear pond water cultivation.

Qingtang has two key points, first: exposure to the sun for 1-3 months; Second: quicklime clear the pond, after exposure to the sun, water 5-10cm, dig a few small holes evenly around and in the middle of the pond, and add water to dissolve the quicklime.

A few days in advance, wait for the water quality to stabilize before putting seedlings, and use a dense net to prevent all kinds of debris from entering the water; It is recommended to cultivate a pond of fertile and stable good water, which can be used with tea seeds, organic fertilizer, inorganic fertilizer, etc., and the water quality requires PH, ammonia nitrogen, and nitrite to be in a reasonable range.

3. Stocking of fingerlings.

In order to ensure the survival rate of breeding, the stocking size must be more than 3 cm, and 1000-1500 mandarin fish fingerlings of 3-4 cm per mu are generally stocked.

4. Feed feeding.

Provide palatable, sufficient, healthy bait fish is the basis for the success of mandarin fish farming, mandarin fish feed live fish and shrimp for life, different growth periods have different requirements for the size and intake of bait fish, specifically: fish species breeding period bait fish accounts for 50%-70% of the body length of mandarin fish, and the amount of eclipse accounts for 50%-70% of the body mass of mandarin fish. Forage fish account for about 30% of the body length of mandarin fish at the grow-up stage, and the amount of solar eclipse accounts for 10%-20% of the body mass of mandarin fish.

5. Daily management.

1) Frequent patrol of the pond: find that the mandarin fish swims slowly or dies in time to check and catch ashore at the same time, observe whether the bait fish is sufficient, whether the mandarin fish chasing fish is normal, and learn to see the mandarin fish feces, the feces are loose and the end is yellow, there may be enteritis, and finally anti-theft measures must be taken.

2) Oxygenation: dissolved oxygen limits the output, multi-oxygen must be prolific, and at the same time it is necessary to increase oxygen, it is recommended to open the aerator on rainy days, at night, and add fish larvae on the same day.

3) Water quality management: ammonia nitrogen, hydrogen sulfide, nitrite, and pH value in the pond need to be tested on a regular basis, and biological agents should be used regularly for water quality control.

In general, mandarin fish farming is highly profitable, but if you want to get a better income, it is very important to master scientific farming technology, and the focus is also on combining the growth habits of mandarin fish to provide a good living environment for them.

When breeding live crucian carp, we must pay attention to the temperature problem, and also pay attention to the feed problem, never feed the live mandarin fish with low-quality feed, and also pay attention to the water quality problem, do not let the live mandarin fish grow in a very poor water quality environment, but I think the most important point is that when breeding live mandarin fish, we must pay attention to safety issues, do not let yourself be injured.

The air quality in the rainwater of breeding live mandarin fish should also be planted with some aquatic plants, some nutrient solution should be added to the water, and the fish should be fed at intervals, so that it can be better, and can ensure that the fish live more fat.

Pay attention to the choice of ponds, you can carry out artificial breeding, or understand the way of breeding, you can also regularly change the water source, pay attention to the selection of feed, in the breeding process, we must pay attention to the selection of varieties, it is possible to carry out outdoor breeding.

You can carry out artificial breeding, or outdoor farming, choose high-quality water sources, pay attention to the surrounding environment, pay attention to the cultivation of fish fry, and understand the basic breeding technology.

Pay attention to the choice of ponds, you can carry out artificial breeding, or understand the breeding method, you can also regularly change the water source, pay attention to the selection of feed, and pay attention to the selection of varieties during the breeding process, you can carry out outdoor breeding.

1. Pond construction.

Mandarin fish look must need to prepare the pond, if there is a ready-made pond then there is no need to dig, only need to clean up the debris around the pond, and then dig the riverbed of the pond, and then dig out the silt accumulated in the pond, and finally sprinkle a layer of lime into the pond for disinfection, about ten days and half a month later, it will be almost, then we can inject new water into the pond, and we also need to apply an appropriate amount of organic fertilizer to the pond, so as to ensure the fertility of the pond, It can provide some food for the mandarin fish to a certain extent, and it can also maintain the water quality that the mandarin fish needs to survive.

2. Fry selection.

The quality of the selection of mandarin fish fry also determines the survival rate and quality of mandarin fish, so we must choose high-quality fry, then how should we choose, I will teach you a little trick, first of all, we have to ensure that the size of the same batch of fry selected is basically the same, and secondly, we can not choose which is lazy, no vitality of the fry can not be selected, and then it is necessary to see whether the tail of the fish is powerful, and the powerful is a good fry. Also, the mandarin fish fry should look relatively clean and unbruised, so that's pretty much it.

3. Stocking density.

The density of mandarin fish stocking is also a basic condition for the survival rate of mandarin fish, generally just beginning to breed friends can choose to stock only a thousand or so per acre, because the breeding technology is not mature, if a large number of breeding is at a time, so it can not be managed at all, it will cause a large number of ** rate, so a thousand is the best, and so on in the later stage there is a certain breeding experience, the appearance of equipment and other good hungry time can increase the number of breeding, About one acre can be stocked 1,500 to 1,008 tails, and the maximum feeding amount of one acre can only be about 1,008, if you want more, you can only expand the area of breeding.

4. Feed management.

Mandarin fish is mainly fed by catching small fish and shrimp in the water, followed by plankton in the water, and finally some feed prepared according to the formula. Therefore, we need to put a batch of other fish with faster reproductive ability in the pond to provide food for the mandarin fish, such as crucian carp, carp, etc., which can meet part of the needs of the mandarin fish, and secondly, we need to put some purchased bait fish into the pond every four to five days or so, to fully meet the needs of mandarin fish, it is best that the bait fish have the remaining time, and finally put feed every ten days or so to promote the growth of mandarin fish.

5. Disease prevention and control.

Mandarin fish is different from other fish, other fish basically have no disease, and its whole growth process has a large number of bacteria and parasites, which will affect the growth of mandarin fish, so we should pay great attention to it, and secondly, because mandarin fish are mainly used to eat live fish and live shrimp, so the medicine used to take them does not have much effect, so we can only solve these diseases from the source, such as regularly cleaning the pond, and cleaning up the suspicious impurities. The second is to change the water in the pond regularly to ensure the quality of the water, and to carry out regular disinfection and sterilization.

1. In order to ensure the survival rate of mandarin fish breeding, it is required that the stocking specifications must be more than 3 cm, and generally about 1000-1500 mandarin fish fingerlings of 3-4 cm per mu are stocked.

2. Bait fish cultivation in the same pond: the early bait fish cultivation can be carried out 15 to 20 days before the stocking of mandarin fish fingerlings. Generally, 50 800,000 pieces of bream, grass carp, silver carp and bighead carp are put into the coarse return beam per mu for mandarin fish to feed in the early stage.

At the same time, in order to reduce the cost of forage fish, some fast-reproducing bait fish parents can be mixed in the mandarin fish pond, such as 200 400 pairs of tilapia per mu or 500 2-year-old crucian carp, and the offspring of rock transportation can be used as live bait fish for mandarin fish to feed. Of course, it is also possible to divide the pond into two parts with a moderate size of thin nets, and raise the bait fish parents while raising mandarin fish, so that the juveniles that reproduce can pass through the thin nets and become bait for the mandarin fish.

3. Feeding of bait fish cultivated in special pools: In the high water temperature and rapid growth period of mandarin fish, when the bait fish in the mandarin fish cultivation pond is insufficient, you can supplement feeding the bait fish cultivated in the special pool every day, of course, the feeding amount is based on the principle of maintaining a certain density of bait fish in the water body and increasing the predation opportunity of mandarin fish. The size of the forage fish is 30% to 59% of the body length of the mandarin fish, and the feeding and growth of the mandarin fish and the individual differences of the mandarin fish should be checked frequently.

In the bait fish, it is necessary to match the appropriate amount of bait fish of different sizes to ensure that the mandarin fish of different sizes have sufficient and palatable bait. It is important to note that the bait fish must be disinfected first.

4. Water quality control: Because of the high stocking density and large amount of bait in the mandarin fish breeding pond, the residual bait and a large amount of feces have a great impact on the water quality of the pond. Therefore, in addition to requiring a good pond inlet and drainage system, regular replacement of pond water, and keeping the minimum dissolved oxygen of the water body at more than 4 milliliters during the whole feeding process, it is also necessary to equip the mandarin fish breeding tank with an aerator.

The start-up time of the aerator needs to be determined according to the specific situation, and at the same time, lime water should be regularly sprinkled to regulate the water quality, and other management measures are basically the same as those of domestic fish farming.
