Problems solved by technology

However, due to the restriction of cage culture by pond water conditions, the culture cycle is short, prone to disease, and the output is unstable; while industrial greenhouse culture has high yield and controllable conditions, but requires a large investment in the early stage

Embodiment Construction

[0015] In order to better explain the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but they do not limit the present invention.

[0016] figure 1 , 2 The shown soil-based greenhouse net cage recirculating water farming eel equipment includes a breeding greenhouse 1 and a reservoir 2, and the bottom of the breeding pond 3 and the reservoir 2 are both covered with anti-seepage cloth 10 .

[0017] Each breeding greenhouse 1 is rectangular, 6-7m wide, and covers an area of ​​100-220m 2 , each breeding greenhouse 1 is provided with a channel 1.1 with a width of 0.7-0.8m that divides the breeding greenhouse 1 into two parts.

[0018] A cultivation pond 3 with a depth of 0.6-0.8m is provided in the cultivation greenhouse 1, and a cofferdam 4 to prevent rainstorms or other currents from rushing into the cultivation pond 3 is arranged around the cultivation pond 3. The height...

Abstract

The invention discloses a method for cultivating rice field eels in circulating water of net cages in soil-based greenhouses, which comprises the following steps: 1) selecting a breeding area; 2) building a breeding greenhouse and a water storage pool; 3) erecting net cages. The invention realizes the control of the rice field eel breeding conditions through the sunshade heat preservation shed, the net cage, the breeding shed and the water storage pool, and then achieves the purpose of stably increasing production. Compared with pure pond cage culture, the present invention has the advantages of controllable culture conditions, long culture cycle, less disease and easy management, and does not require huge initial investment like industrial culture of rice field eel, and is a low-cost and high-yield rice field eel Breeding facilities have the advantages of increasing eel breeding cycle, high and stable output, less disease and easy management.

Description

technical field [0001] The invention relates to a breeding method, in particular to a method for cultivating rice field eels in circulating water of net cages in soil-based greenhouses. Background technique [0002] Swamp eel is a kind of main economic fish in my country because of its tender and delicious meat, high protein content and rich nutrition, which is deeply loved by consumers. At present, there is a large gap in the production of rice field eels in the domestic and foreign markets, and the demand is gradually increasing, which has a good breeding prospect. [0003] At present, there are three ways of cultivating rice field eels: net cage culture, industrial greenhouse culture and paddy field culture, among which cage culture is the main production method. However, because cage culture is limited by pond water conditions, the culture cycle is short, prone to disease, and the output is unstable; while industrial greenhouse culture has high yield and controllable co...
