Where are the flower eel seedlings How to breed flower eels? Where is the Jinxing flower eel?

According to the physiological and ecological characteristics of flower eel (Anguilla marmorata), a recirculating aquaculture system was constructed. The system integrates key technologies such as ozone disinfection and sterilization, mechanical filtration, biological filtration, and liquid oxygen oxygenation. All water quality indicators were maintained within the suitable range for the growth of flower eel. After 260 days of culture, the average weight of the flower eel with an average size of g reached g, the survival rate reached a fish yield of kg m at the time of harvest, the bait coefficient was maintained at about 1 m, the breeding cycle was shortened by 4 to 5 months compared with the traditional culture mode, and the daily water change rate was about 3%.

It is feasible to use the closed recirculating water aquaculture model for flower eel culture.

You can breed, but you must go to Xiamen to learn technology.

Flower eels are born in the ocean, grow in freshwater, and finally return to their birthplace to end their lives. "It is difficult to successfully breed this fish from small to large in fresh water, but now in Jimei, it has become a reality through artificial breeding experiments. On July 16, the author learned from the agricultural department of Jimei District, Xiamen, that the experimental project of artificial breeding of flower eels in the district passed the acceptance of the expert group, and is actively doing a good job in the follow-up experimental work and breeding technology summary, through the introduction of new varieties and the promotion of new technologies, effectively help farmers adjust the structure and promote income.

According to Xu Hongyu, director of the water technology station in Jimei District, Xiamen, the flower eel, also known as the reed eel, is a national second-class protected animal. It grows in tropical and warm temperate estuaries, rivers, lakes, rivers and swamps. Flower eel has been regarded as a treasure in food by the Chinese since the Sui and Tang Dynasties, and Chinese medicine believes that "boiling soup with five flavors can make up for weakness and long-term illness".

Zhejiang Linhai County Chronicle called this "eel king", is the lower reaches of the Yangtze River and China's coastal areas of the famous precious edible fish. In recent years, due to factors such as environmental impact and man-made overfishing, this rare aquatic product resource has been decreasing day by day and is on the verge of extinction.

In order to increase the total amount of flower eel resources, save the endangered flower eel population, and at the same time meet the urgent market demand for flower eel through aquaculture development, and promote the industrialization of flower eel breeding and the sustainable utilization of resources, in March 2007, Xiamen Jimei District set up a flower eel artificial breeding experimental base in the rural area of Guankou Town. The project was organized and implemented by the agricultural department, and the experiment was undertaken by the District Aquatic Technology Station and the Guankou Town Agricultural Technology Center. After more than a year of practical efforts, it has been successful.

After that, the organization of technical forces on the breeding habits, breeding technology observation, research, and get a useful attempt.

According to reports, the body of the flower eel is long and cylindrical, the dorsal edge of the head is curved, the snout is slightly flattened, and the tail is slightly flattened; eyes small, oval, superior lateral, covered with hyaline epithelium; jaw slightly protruding, toothless; The body is covered with fine scales and buried under the skin; The dorsal side of the body is densely covered with yellow-green patches and spots, the abdomen is creamy, and the pectoral fin margin is yellow. Common individuals are 70-80 cm long and weigh about 5 kg, with the largest being over 230 cm long and weighing 50 kg. After trial breeding, we not only understand its special requirements for water quality and feed, but also master its disease prevention and breeding rules.

At the end of last year, the expert group of Xiamen Breeding Farm and Jimei University believed that the flower eel, as a national second-class protected animal, is a famous and precious edible fish in China, and has great development potential, so it is of great significance to carry out artificial breeding experiments of flower eel from the perspective of protecting and rationally developing flower eel resources. Experts suggest that Jimei District should do a good job in follow-up experimental work and breeding technology summary, and continue to support and subsidize it.

Due to the serious pollution of the river by industrial toxic sewage and overfishing, as well as the devastating damage to fish resources by toxic and electric fishing methods, the construction of dams and dams and hydropower stations to block the normal migration passage of flower eels, etc., the resources of flower eels have declined sharply, and it is difficult to see their traces, so flower eels are endangered species and are protected wild animals at the national level in China.

Flower eel is one of the typical migratory fish species that descends into the river. It grows in estuaries, swamps, streams, lakes, ponds, reservoirs, etc. Fierce in temperament, strong and powerful.

During the day, they hide in caves and rock crevices, and go out at night to hunt fish, shrimp, crabs, frogs and other small animals, as well as the carcasses of large animals that fall into the water. It can forage in wet grasslands outside the water and in bamboo forests and bushes after rain. Its feeding area is mountain streams in the Philippines up to meters above sea level.

In China, it can reach Tiantai Mountain, North Yandang Mountain, South Yandang Mountain in Zhejiang, Changting in the upper reaches of the Hanjiang River in Fujian Province and Changjiang Jiangyuan in Hainan Island. It can leave the water for a long time, so sometimes it also climbs the river beach at night and hunts frogs, rats and other larger animals in the reeds, so it is called the reed eel. When it snows in winter, it is also common to move in shallows and other places on the shore, so it is also called snow eel.
