Ricefield eel culture method

Abstract

The invention discloses a ricefield eel culture method. In two years when a young ricefield eel is cultured into an adult ricefield eel, a cement pit culture method is used in the first year, and a net cage reed culture method is used in the second year. Each young ricefield eel is caught in the wild with the weight of 60-90g, and the weight of each adult ricefield eel is 160-210g. The ricefield eel is cultured in a cement pit from May to September, is moved to be cultured in a net cage in February to March in the first year and is sold as the adult ricefield eel in November to December the next year. The cement pit consists of a plurality of small pits with the width of 4 meters, the depth of 0.9 meter and the length of 5-6 meters, a drainage sign and a water inlet sign are respectively arranged on one edge of a pool to form an opposite angle, a drainage pipe hole is provided with an escape-prevention net, and the pool wall is covered with one layer of plastic film. According to the ricefield eel culture method disclosed by the invention, the cement pit culture is carried out in the first year so as to bring convenience for observing the eating and moving situation of the ricefield eel, and acclimatization is better. The ricefield eel cultured in the cement pit has the advantages of proper size, good freshness and good oxygen dissolving performance, and only water needs to be supplemented in fixed time. If the young ricefield eel is successfully acclimatized in the cement pit, the young ricefield eel can quickly adapt and eat when being moved to the net cage, the growth period is prolonged, and the weight increment ratio is big.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating rice field eels. Background technique [0002] Swamp eel, also known as eel or long fish, has tender meat, delicious taste, less bone spurs, rich in protein, a variety of vitamins and minerals. Swamp eel also has important medicinal functions, such as invigorating qi, nourishing blood, reducing inflammation, and disinfecting. , expelling wind and dehumidification and other effects. At present, it is increasingly favored in the domestic and foreign markets, and the supply is in short supply. Rice field eel has strong adaptability, resistance to low oxygen and hunger, and is easy to transport. Its breeding method is simple, low in cost, and high in economic benefits, and is suitable for small-scale family farming. In the next 5 years listed by the State Information Center, 6 farming projects with great development prospects include rice field eel farming. In a...

Problems solved by technology

The wild eel resources are limited. With the improvement of people's living conditions, the demand for eels has risen sharply. Wild fishing is difficult to meet the needs of farms. This requires large-scale artificial breeding of rice field eels.

Since the artificial breeding of eels has not been completed, all eels are caught in the wild. Wild eels live in the natural state for a long time, and mainly feed on aquatic plankton that prey on live fish, live shrimps, tadpoles, and water earthworms. It is difficult to achieve these conditions in large-scale farming, so it is necessary to domesticate the eel to eat and artificially formulate the feed. It is difficult for the eel to adapt to the environment when it has just entered the artificial pond. , so it is difficult for small eel species to reach the market specifications in the first year, and they must be bred in the second year before they can be marketed
