[Edit this paragraph] Overview of classification
Arowana is divided into red pepper dragon, red blood dragon and orange dragon. There are different grades. The higher the grade, the more expensive the price, and the red pepper dragon is needed. Dragons and red-tailed dragons have the same body. Scaly fish box, snout, gill cover, fin and tail show different degrees of red. The segments are orange, pink, dark red and blood red. Obvious erythema on branchial lid.
1 Red Dragon
1 Red dragon is mainly red, and the detailed vest can be divided into two types: red pepper dragon and red blood dragon arowana (Figure 6). The seal and scale of the red cheek frame of red pepper dragon are mainly bright red outer edges, and the fins are also red, with a red nose. If you turn off the light (red wavelength, because the fish tank is illuminated and turned on, the color of the fish is not completely correct), Libra is blue-purple. Import protection restrictions are imposed on the red dragon species you want to buy arowana. In fact, it is not so easy, because almost all small arowana (from small to large arowana, the color change of arowana has not changed among children). Generally, there is no red pepper dragon in the arowana in the aquarium, because the wholesaler on the stage has been selected. Provide a way to buy a good red dragon: it is better to have red body color or red spots in the period of Xiaolong. Blood-red dragon's body color and red pepper red dragon red scale frame, there is no obvious dark red gill cover India, only the body distribution is very uniform, but the color is mainly red.
2, dragon (orange dragon)
2, Dragon's navel orange The young arowana has smooth lips and unclear head. The gill cover of the adult arowana is orange or light orange, and the fins and tail fins are not red or light orange, and the tail is orange or no color. Arowana arowana keeps the characteristics of no more than 1 arowana. It is possible that the red-tailed dragon or dragon will not turn into a red body at the back. How to raise it, but it has no complete appreciation value and does not buy and feed it, so that it can develop a proper body color, which is also a good dragon.

Sex determination in the process of artificial reproduction has been able to be so handy because of the skills of sex identification from arowana. In the eyes of the industry, it seems possible for male arowana to take orally for future breeding. A female fish whose pectoral fin is crimson and the fish itself is slightly slender, it can easily find the observation above the fish pond. In addition, female arowana is fatter than male fish, and its abdomen is more likely to feel distended, and its pectoral fins and head are darker than male fish. [2]
[Edit this paragraph] Overview
Brightening and chromogenic condition
It's just that the red dragon is red and the red dragon is golden. It's not allowed to be green and red, but of course it doesn't include improper Yang color. Let's talk about the Yang color method. The purpose of hair color is the only way to achieve fish's water quality, environment, lighting, and feed management, but it emphasizes that Arowana's performance is 70% of its excellent pedigree, while the remaining 30% significantly affects the acquisition management. Water quality of arowana
I believe all friends know that in order to maintain good water quality, it is generally recommended to change the water several times, but if the medicine bathtub is abnormal. Usually, the water 1/3 1/5 per week (depending on the fish or excretion on the cylinder) should be avoided, and the bait must be removed to avoid the deterioration of water quality. Weak acid soft water is generally good in quality. Water softener can create mountain spring water, RO pure water or soft water tree quality; Autumn black water from the sky, grass mud pills, or Amazon soil acidity can be added to create. /> environment
Environment, including shift cylinder, medication, background color, and so on. In fact, the fact is that the change of environment leads to the fading of fish, in the case of arowana. The body pigment of arowana is only connected to its scales, so any impact on the environment will affect the color of the human body and the performance of arowana. Background color, red and black, red, or blue. Jinlong is mainly blue or black. According to the color of arowana. Lighting, red dragon put forward to the weak optically active plant lamp irradiation is better. Jinlong is dominated by blue light and white light. In fact, whether it is a plant lamp or a fluorescent lamp, the weak optical activity should be better in the choice of lamps, because if it is irradiated by too much light, the body color of Arowana will become lighter. The background and color of the arowana lantern shall prevail. That is to say, when the cylinder drops to a height of about 10 15 cm, it is easier to lure the color to achieve the purpose of preventing the eyes, and the pressure of the water will be reduced.
[Edit this paragraph] Yang color
Slightly larger four-poplar color
Features Holstein monga Synthetic Pigment: The fins all show bright red color. Identification: This method is at first glance to our eyes, because the brightness of the color fin and the bottom of the scale will be in direct proportion to the contrast. Usually, the background color of arowana (black or green), the fin will be redder and the darker the color. Improper Yang color will show that the background light of Arowana is white or the scales are bright enough, but only the fins are bright red. This method is to inject hormones or red pigments, which will lead to fading color effects in the future. This method is not difficult for an experienced veteran to see through because it looks unnatural red. In addition, Arowana's lips will appear orange (red). The characteristics of injection pigment, unless there is another way.
The characteristics of feeding synthetic pigments: the body color part is pink. Identification: bright red color, but it is easy to identify because the heat sink or part at the bottom will show pink color. This method is fed with artificial pigment, and desalination is the only result.
Hungry yang color
Features: Most of them have small eyes and a slender figure. Hair color is redder than the average figure. Appraisal: It is not difficult to see through it when you look carefully, because you will feel like an old urchin. This method, but by controlling the feed. Generally, arowana can grow to 30 cm a year, but this method can be controlled at about 20 cm. This is a fish of the same age. On the other hand, if you feed a hungry fish with a length of about 20 cm, but the hair color looks like a performance of 30 cm.
Blind dragon
Features: fish, but the phenomenon of amblyopia or blindness in fish eyes is strong. Identification: this method is a method of laser or other methods to stimulate the body color and make it amblyopia or blindness in adolescence. Arowana, because it is said, in the dark world. Its body color will be dark (black). On the contrary, it will produce a strong red color. [3]
[Edit this paragraph] Outline the population situation
Many people think that artificial breeding of red dragons is just groundless. From 1995 to the continuous import of excellent red dragon individuals from Singapore and Malaysia, we really understood why. Originally in 1950, Asian arowana was widely distributed throughout Southeast Asia: clues from Indonesia, Vietnam, Thailand and Malaysia, including the fact that local residents are extremely important natural foods. Arowana grows in clean river water, changing the color of the car body, such as orange, blue, red and gold, and the color difference of platinum. In fact, from different origins, it leads to the difference of endemic species. It seems that arowana is distributed around the equator, with abundant rainfall and annual average temperature, which is a very typical tropical and subtropical climate. Pure water above 20 degrees Celsius will become an integral part of the ecological conditions of arowana. The water in the habitat of wild red dragon has a pH value of 6.4-6.8, a hardness of slightly less than 8, and contains slightly softer than average sodium bicarbonate and a small amount of calcium. In the original habitat, the color is also cloudy, and the impression is different from that of the traditional large tropical rain forest. Arowana originated in Southeast Asia, and it is a muddy soil riverbed with dense plant growth, which provides an excellent hiding place. Natural wild arowana, sleeping arrowhead grass and even a bottle of brandy are the best natural barriers to avoid these huge aquatic plants, and we can more easily prevent the eagle family from hunting frogs, shrimps, small fish and other live bait prey sources. It is a very difficult project for the three countries that have successfully exported the red dragon: Singapore, Indonesia, Malaysia, and the red dragon that is regularly and quantitatively produced. Recovery, Red Dragon, the new Singapore government and non-governmental organizations cooperate, and the operational efficiency is regarded as the best in Southeast Asian countries. On the one hand, research in the whole country will be resumed, and on the other hand, Washington will organize Singapore governments at all levels to adopt chip implantation, confirm it and license it. Finally, Singapore and later became the first Asian country in the world to export Fuyu Red Dragon, and it was the first country to export live implanted electronic chips. The juvenile red dragon exported from Singapore is about 20 cm long, and the standard price is about 134 USD. The main exporting countries are Japan and the United States. The technicians of Xinpo Origin Bureau polyculture 10-20 mature arowana (at least 50 cm) in the outdoor pool by reproducing the simulation time of semi-natural ecosystem. Mixed vegetation naturally matches the semi-emergent plant pool of arowana, which can be used for nesting and spawning. Mild water, and keep daily frozen bait, surimi feeding, even if it is possible, but the color control, as much as possible as possible the green color, or parasites can easily get into trouble with large fish hypoxia and so on. From the end of each year1October to the early March of the following year, the strong red dragon mating season, especially in the peak period of 1 1 month to1February. There is a lot of fresh water at 24 degrees, and female fish can often stimulate ovulation quickly. Female fish lay eggs (Figure 3) Male and female fish parade in shallow water with high visibility, closer to the left and right, close to each other, until the abdomen. It takes about 1-2 hours to mate, but in fact, the female spawns only about 20 minutes. Spent the rest of the time consuming artificial insemination, as well as food, containing eggs in the mouth by men. The male arowana, who is responsible for oral hatching and egg protection, and the female fish are not expelled, serving as a guard. All the actions are under muddy water, so at the beginning of the recovery, arowana swallowing eggs every day is often heard. In this way, technicians who improve the survival rate of larvae begin to shake eggs out of the male population at an early stage to reduce losses, which is said to be the key to successful reproduction. Many people let arowana mate and lay eggs without knowing it, but they didn't feel or miss it at all. In Singapore, the male population and the egg are about 50 days, and the record will be recharged to let the small fish swim out. The small arowana is at least 6-8 cm long, so it is often stuffed by men orally. It is also speculated that men's growing grain will reduce the oral problems of some eggs from future productivity. However, in any case, it is often true that only 30% of teenagers can survive. Now, the breeding technology has become more mature. Technicians usually shake out the newly hatched young arowana when the fish has gradually begun to hatch about 14 days after spawning. As a result, the success rate often increases by more than 80% and is exciting. A mature arowana can usually produce 1-2 times a year, laying 50-80 eggs each time, upward and downward. However, in the future, it should be a higher capacity, and the young arowana will grow to about one year, and it can grow to nearly 1 kg. Therefore, between the profits of Southeast Asian governments, everyone regarded it as an excellent source of income and made a lot of foreign exchange income.
Singapore
In Singapore, the legal procedures for chip implantation and registration of arowana larvae cost about $78 million. However, once registered, the qualified red dragon seedlings (2 inches), about 5 cm, cost nearly $ 1000, and the demand is still in short supply. 106 Washington convention member countries, only three South Asian countries (Singapore, Malaysia, Indonesia), 1 m 12, the hotbed of the red dragon's right to breed offspring. Among them, Indonesia monopolizes 8, Malaysia catches up, accounting for 3, while Singapore's public-private partnership, rehabilitation center.
Indonesia and Malaysia, rich in natural resources and unique geography, are close to the place where the arowana is restored to the origin of the red dragon. Therefore, since 1983, the Indonesian government, as the national biological red dragon, and three East Asian countries have fully participated in the long-term and complicated charging culture listing. Compared with densely populated Singapore, the water quality of the origin of Malaysian and Indonesian red dragons and the introduction of high quality can almost alleviate a large number of curved rivers that simulate the natural environment or natural pond culture. Export action, speed, Indian, China, Malaysian and Singaporean soon. However, due to the rich biological resources, the interest income of Red Dragon will be observed accurately and accurately. According to the information provided by the Malaysian Fisheries Bureau, the growth of the red dragon in an aquatic environment close to nature may be due to the correct temperature of water and food around for about three years, and it can be used to lay eggs when it reaches a mature age. In Malaysia, because of its rich fish resources, it is a fish breeding, breeding and mating gate, and even young fish can move independently to separate the cement pool. Generally, the pond is rectangular in height, with a width of at least10m and a length of about 30m, and the water depth is between180cm and150cm. The water quality of the pond continues to control the PH value to 6.5, and the turbidity of the water is between 25 and 28 degrees Celsius. The fish slurry in the daily feeding place will be moved into a more mature dragon fish pond after the seedlings grow to a certain scale. Usually, the quality of groundwater (well water) near the pool is mixed with tap water. Slightly carbonate, muddy particles, water, milk color, coffee color, low visibility (10-15cm), fish farms under slightly different circumstances, but in Singapore, according to the arowana explained by Malaysian industry, the quality of this water will become stronger. However, it seems that a large amount of new water is normal every day, which has become a necessary national formula. In particular, they will choose a fish pond for male and female arowana, and another quiet swimming pool will let them interfere in the environment, and gradually chase, dance and lay eggs. The situation that males and females attack each other or fresh eggs will be greatly reduced, in such a leisurely environment. In particular, the design of the bottom of such a fish pond is a bit special, that is, shallow water-filled floating plants are supposed to be in use in deep water areas and shallow pools, which are said to be in spawning and arowana mating action. Return on net assets (Figure 4) The time for males to contain eggs, with the water temperature of 45-60 days, the egg production decreased, and the diameter of eggs, at least 1.5CM, was slightly different. Under artificial incubation, the success rate is often as high as 8%. After 45 days or so, after artificial incubation of arowana larvae, you can eat all kinds of plankton in the water, fish can stay in 2-3 months, and red dragons can easily reach 10 cm or more. Without artificial incubation, the small arowana is a giant of at least 8 cm in length when it freely imports and exports male fish, and its body length has reached commercial sales. Japan
Japan's domestic price, an 8-inch (20 cm) red dragon, sold the spectrum of about 3000 yuan. According to the production strike, it has rarely been called male personal care. However, after about two weeks, the production of arowana can be improved by removing the male's mouth from the semi-yellow and slightly bloodshot arowana eggs and changing the artificial bubble simulation incubator.
