#19th Agricultural Fair #Eight-whisker catfish is a new alien species, which has great similarities with the native catfish in China, and is a species of the same family, a wild fish native to the Nile River Basin in Africa. Because this fish farmed in various parts of our country is introduced from Egypt in Africa, it is also called Egyptian pond lice or Egyptian pond lizard.
The main reason for the introduction of species in China is that this catfish, which is very different from the native species in China, is the best new species in the catfish family. It has a very strong adaptability, can adapt to different climatic conditions of the water, the diet is extremely extensive, basically there are no animals and plants are not eaten, and the body is large, fast growth, can tolerate low oxygen environment, with super reproductive ability.
China was introduced from Egypt in 1981, successfully cultivated in freshwater aquaculture in Guangdong Province in 1982, and promoted aquaculture in the Jiangnan water village area, and has been introduced into the country for 30 years. Because, the culture of the eight-whisker catfish does not need to be finely farmed like other fish to obtain a good yield, while the eight-whisker catfish only needs to be released in the pond after the seedlings are released, and they can grow without management or food and reach the level of abundant production.
Therefore, the eight-whisker catfish has less investment, no need for breeding technology and breeding management, can not feed, can rely on eating natural animals and plants to achieve the purpose of abundant production, without investment can generate income. If it is artificially carried out high-density aquaculture, it is basically a three-dimensional high-density environment of fish and fish, as long as there is no lack of food, it can also grow, reach an unexpected high-yield level, and will not cause disease, which can create the miracle of high-density breeding.
Due to the widespread promotion in rural areas of Guangxi, Guangdong, rural farmers are very fond of this "lazy" fish farming, which can obtain very high economic benefits. Therefore, farming in these areas, because it is not carefully managed, when it rains, there will be a lot of eight-whiskered catfish fleeing with the water.
After escaping, the eight-whisker catfish live in the waters of nature, the adaptability is very strong, the food in nature is very abundant, so the breeding rate is accelerated, the reproductive capacity is enhanced, and natural reproduction expands to all the waters in the south, including the rural sewage ponds in the south, sewers, sewage pond pits in the farms, stinky ditches, farmland, and wild water ditches, as long as there is water for a long time. Eight-whiskered catfish are able to live and grow, and the growth rate is amazing, growing very fat, spreading throughout the waters, becoming the hegemon of the new waters of the southern waters.
At its most disgusting, the eight-whiskered catfish likes to be in the dirtier places, growing very strong, such as southern stinky ditches, toilets, sewage ponds on farms, etc. Where people disdain, eating human and animal feces and animal remains discarded by rural people, it looks very disgusting. In order to eliminate the eight-beard catfish, the rural people fished for piles of eight-beard catfish ashore from these sewage areas, rinsed the house with clean water, and sold it to fishmongers for one or two dimes a pound.
Therefore, anyone who knows wild eight-whisker catfish does not dare to eat these wild fish at all. Consumers are afraid that the eight-whisker catfish live in polluted waters and contain a large amount of heavy metals in their bodies, but also fear that they will carry unknown harmful diseases and germs. Therefore, most of the people in the south who are familiar with the wild eight-whisker catfish do not eat this fish
Therefore, the eight-whisker catfish cultivated in the southern countryside has become a popular product in the market and a new darling variety in the eight-whisker catfish product. The difference between farmed and natural wild is in body size and fatness. Artificial breeding is high-density breeding, insufficient feed, relatively small body shape, a year can generally grow 1 to 1.3 pounds of weight, the size is basically the same, and thin, not very fat. The size of the wild eight-whisker catfish is inconsistent, some are large and some are small, and the weight is several pounds and dozens of pounds, which is very fat.
The knowledgeable people in the south only buy artificially fed ones, not wild ones at all. This is the main reason why rural farming of eight-whisker catfish has become the "new darling".
