The origin of arowana
Arowana, a kind of large freshwater fish belonging to the family Osteoglossidae, began to appear on the earth as early as the Paleocarboniferous (360-290 million years ago). After the changes of geographical environment in various times (such as plate drift and climate change, etc.). ), evolved into several races with different appearances, which are now distributed on all continents.
Arowana, whose origin is called arowana, is pronounced as "arowana" in China and means "long tongue" in Spanish. Because it is huge and flat, its trunk is covered with huge, neatly arranged, shiny scales, its mouth is big, and its lips have two beards. It swims around leisurely, just like the mythical "dragon", so it is named "Arowana". It still retains the physical characteristics of ancient times and is known as the "living fossil of fish".
Arowana was officially discovered by biologists in 1829, when it was named by American ichthyologist Doctor of Temperate Science in the Amazon River Basin of South America. 1933, a French ichthyologist, Dr. Belugalan, discovered red arowana in Saigon, Vietnam. 1966, French ichthyologists Bran and Doberton discovered another kind of arowana in Phnom Penh. Later, some scholars discovered other arowana in Vietnam, Malaysia Peninsula, Sumatra, Bangka Island, Biboro, Thailand, Australia and Africa. Arowana is subdivided into Asian arowana, American arowana, Australian arowana and African arowana according to geographical distribution.
Development of Ornamental Fish Arowana
Although arowana was found in 1829, it was always used as food fish by local aborigines at first. Since 1950s, it appeared as an ornamental fish in aquarium culture in North America, and then it developed continuously, until 1980s, it gradually became popular all over the world.
Asian arowana first set off a wave of breeding in Southeast Asia. Because it looks like a dragon, it looks like a dragon. Some overseas Chinese businessmen in China who are doing business in Malaysia and Indonesia introduced it as a lucky fish to aquarium culture, and then it gradually became popular throughout the cultural circle, establishing the sacred position of Arowana as a feng shui fish. The rise of this trend has also made the indiscriminate fishing of arowana popular. 1980, the Washington convention organization listed Asian arowana as an endangered animal, and banned fishing in its habitat, gradually making it a luxury for individuals to raise Asian arowana. Until 1989, the seventh plenary session of the Washington convention was held in Lausanne, Switzerland, and Indonesia was given a limited export quota, but the export quota did not exceed 1500. Moreover, these limited export quotas are the second-generation arowana bred in an Asian arowana place in Indonesia, excluding wild individuals. With the gradual maturity and stability of artificial breeding technology, at the 9th General Assembly of Washington Convention Organization held in Florida, Indonesia demanded to cancel the quota. On August 25th of the same year, Rainbow Fish Farm in Singapore and Xianglong Fish Farm in Malaysia applied for registration with the Washington Convention, and were allowed to sell the third generation and later Asian arowana. However, the Asian arowana required to be sold must be implanted with a marked electronic microchip as an identification mark when the fish body reaches 13- 15 cm.
