Try not to make the water green, otherwise the problem of parasite and anoxia will easily disturb such large fish. From the end of October to the beginning of March of the following year, the mating period of red dragon is vigorous, especially from November to December. There is a lot of fresh water at 24 ℃.
Brief introduction of Indonesian chili red dragonfish
Red dragonfish, scientific name: scleropage formosus. English Name: Red arowana, with a body length of 80-90cm. Red dragon fish live in a small area, mainly in Sumatra and Kalimantan rivers in Indonesia. The red dragonfish, which could not be propagated artificially, was on the verge of extinction. Therefore, it was listed as a class a protected animal under the Washington Convention and was extremely precious.
The red dragonfish is an ancient fish. It belongs to Osteoglossidae. It has weak reproductive capacity. The female lays eggs and the male hatches and raises in the mouth. It is very strange. Because of the two whiskers on its mouth, the shiny scales and its ancient life experience, people naturally associate it with the mysterious dragon, which is called "dragon fish". In Southeast Asia, Hong Kong, Macao and Taiwan, as well as places where overseas Chinese are concentrated, Longyu is regarded as a god fish, which can be kept as Fengshui fish, especially the red dragon fish. Because of its endangered species, it was listed as a class a protected animal in the 1980 Washington wildlife protection treaty and has a noble status. In Hong Kong, Macao and Taiwan, the price of a red dragon fish, which is worth more than one million yuan, is regarded as a symbol of wealth and status.
How do Indonesian chilopotamus reproduce?
The red dragon can be propagated artificially. Many people think it's just from nowhere. It was not until Japan imported excellent individuals from Singapore and Malaysia in 1995 that we realized it. Before 1950, Asian dragonfish was widely distributed all over Southeast Asia, such as Indonesia, Vietnam, Thailand and Malaysia. It was also a very important natural food for local residents. The change of body color of longfish growing in clean river water, such as orange red, cyan blue, golden red, platinum and other color differences, actually comes from the different origin, resulting in the local variety differences. According to the distribution of longfish, they are all around the equator. Rainfall and annual average temperature are typical tropical and subtropical climate. Therefore, the pure water above 20 ℃ becomes an indispensable condition for the ecology of longfish. The pH value of the waters inhabited by the wild red dragon is between 6.4-6.8, and the hardness is slightly lower than 8. In the water quality of the original place, there are slightly more heavy carbonic acid and a small amount of calcium than the general soft water, so the water color is also relatively turbid, which is quite different from the traditional impression on the water quality of the tropical rainforest. In addition, in Southeast Asia, where the dragon fish are produced, the river bed is mainly made of muddy soil, so the water grass is also very dense, which provides an excellent shelter for the natural wild dragon fish. Among them, the sleeping ganoderma, civet mushroom, and even pingpeng grass are the best natural shelters. Under these huge aquatic plants, they can not only prevent the falcons from killing, but also for frogs, shrimps, small fish, etc The source of live prey is even easier. As far as Singapore, Indonesia and Malaysia are concerned, it is not a very difficult project to produce red dragon regularly and quantitatively.
Among the southeast countries, Singapore's government's cooperation with non-governmental organizations in the rehabilitation of the red dragon ranks first in terms of operational efficiency. On the one hand, we should study the reproduction in China, on the other hand, we should strive for Washington organizations at all levels to recognize and issue licenses for the microchip implantation method adopted by the Singapore government. Finally, Singapore became the first Asian country in the world to export and reproduce the offspring of red dragon, and also the first country to export in vivo electronic microchips. Singapore's young red dragon fish, about 20 cm long, sells at a standard price of about 3000 US dollars, mainly from Japan and the United States.
The technician of Singapore origin bureau adopts the semi natural ecological simulation method to breed 10-20 pairs of mature longfish (at least 50 cm) in the outdoor pool at one time. In addition, some semi emergent plants are planted in the pool for the natural matching dragon fish, which can be used for nesting during spawning. And maintain some micro water flow, daily use of frozen bait, even for the feeding of fish slurry, but in the water color control, try not to make the water color green, otherwise the problem of parasites and hypoxia is very easy to trouble such large fish. From the end of October to the beginning of March of the following year, the mating period of red dragon is vigorous, especially from November to December. A large amount of fresh water at 24 ℃ can often stimulate ovulation of female fish.
