Stage culture method of finless eel

Abstract

The invention discloses a stage culture method of a finless eel. A cement pit culture method is used at a first year and a cage culture method is used at a second year within two years for culturing a young finless eel into an adult finless eel; a cement pit is used for culturing at the first year so as to observe the feeding and action conditions of the finless eel conveniently, the finless eel is better domesticated, various conditions of the finless eel are clearer, the finless eel is more conveniently displaced into and out of the cement pit; the cement pit culture has high cost, the finless eel is displaced into a cage at the second year so that the cost is greatly reduced, and because the culture water surface of the cage is large, water is deep, freshness and oxygen dissolution are good, water circulation does not need to be carried out every day like the cement pit, and only water is regularly supplemented; and finless eel seedlings are successfully domesticated and then can adapt and eat at once when moved into the cage. According to the stage culture method disclosed by the invention, a growth period is prolonged, and a high weight increment proportion is achieved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates 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, multi-vitamins and minerals. Swamp eel also has important medicinal functions. Wind dehumidification and other effects. At present, it is increasingly favored in the domestic and foreign markets, and the supply exceeds the demand. 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. [0003] Existing farming methods for rice field eels include: [0004] 1. Cement pond cultivation...

AI Technical Summary

Problems solved by technology

[0020] Wild eels are limited in wild resources. With the improvement of people's living standards, the demand for eels has risen sharply, and wild fishing is difficult to meet market demand. This requires large-scale artificial breeding of rice field eels

Since the artificial breeding of eels has not been completed, all eel species are wild-caught. Wild eels live in the natural state for a long time and mainly feed on aquatic plankton such as live fish, live shrimp, tadpoles, and water earthworms. It is difficult to meet these conditions in breeding, so it is necessary to domesticate the eel to eat and artificially formulate the feed. The eel has just been raised in the artificial pond, and it is difficult to adapt to the environment. It takes a long time to adapt to the changes slowly. It also takes time to domesticate the eel with artificial compound feed. Therefore, 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. This patent is to use stage breeding to achieve the purpose of reducing costs and increasing benefits.
