Sea eel belongs to the bony fish program eel order eel family, also known as eel, yellow eel, red eel, for fierce bottom fish. Inhabiting in the water depth of 50?80m sandy bottom or rocky reefs in the sea area, swimming quickly, sexual gluttony, ingesting shrimp, crabs, fish, squid and so on. Sea eel meat is tender and fresh, nutritious, in addition to fresh sales and canning, its dry products? Eel replica bags? Best-selling domestic and foreign markets, and eel can be used as fish maw or glue, is one of the main economic fish along the coast of China. In recent years, eel farming has been rapidly developing along the coast of Zhejiang Yan, has achieved very good economic benefits

Eel farming ponds are generally selected about 10-20 acres is appropriate, easy access to drainage, water conditions should be good, the average water level of the pond in the 1.2m or more, the pond dam requires a solid, firm, no holes. The bottom of the pond is soft and good for eels to burrow, but the bottom of the pond can not be too much mud, and can not be black with rotting mud. Half a month before stocking, the pond will be dry pool exposure or with water cleaning and pollution, per mu sprinkled with dry lime 75?100kg, or bleaching poplar 20?25kg / mu, diluted with water and sprinkled on the bottom and sides of the pond, disinfection. In addition, in the pond inlet and outlet gates need to be inserted in the flatbed net, to prevent the eel from escaping.

Second, the selection and transportation of the sea eel to keep the environment dark, reduce the activities of the sea eel. In the whole transportation process, the operation should be careful, fast, as far as possible to reduce the eel dry time, to prevent the eel body secretion too much mucus.

Precautions for eel farmingWhen eels are first introduced to the pond, due to the difference between the pond environment and the sea environment, the eels' activities are intense, and the eels' activities are very intense, and the eels' activities are very intense, and the eels' activities are very intense. The eel will regurgitate and secrete mucus. and secretion of mucus, into the pool 1?2 days to maintain fresh water quality, must increase the amount of water change, the daily water change 100%, in the high temperature season, the day to change the water twice a day, the amount of daily water change to reach 80%, usually the amount of water change every day to control about 50%, winter water temperature drop, fish burrowing does not ingest, the general amount of water change to control the amount of about 30%. The transparency of the pool water should be maintained at 30?50cm, and the water should be kept above 1.2m in winter.

1, disease prevention and control

Biological agents and water quality improvers are used every 15 days during the breeding period, in addition to 2 times a month of rhubarb, yellow

lotus, garlic and other herbs are crushed and mixed with the feed and feeding, which can effectively prevent and reduce the occurrence of diseases. 2, catch-and-release and overwintering management

Catch and release is a good way to prevent and reduce the occurrence of diseases, but it is not the best way to prevent diseases. Eel farming is a technique to increase production, mainly in line with the growth pattern of eel. Eel growth to July eel 50% to reach the specification eel

(0.4 catty / tail), in line with the export requirements, every 1 month catch - - times, before the round fishing stop eating 1 ~ 2 days.

Wintering management is the bottleneck of adult eel farming in my area. The farm has ensured the smooth overwintering of eels by fattening and increasing the water level in the fall.

After October, with the water temperature dropping gradually, the eels will be fed with more fat content in the feed until the water temperature drops to 10?C. The eels will not be fed until the water temperature drops to 10?C. The eels will not be fed until the water temperature drops to 10?C. In the overwintering period, the water level

stayed at about 2 meters, the water table when frozen in time to break the ice to prevent freezing, to ensure the survival rate.
