Embodiment 1

[0025] Example 1. Using as figure 1 and 2 The shown ricefield eel greenhouse culture system is an example of ricefield eel cultivation.

[0026] The specification of the steel frame of the water storage tank is length × width × height = 15 × 3 × 1m, the steel beam at the upper port is a rectangular steel pipe, the section size of the rectangular steel is 5 × 10cm, and the barbed wire enclosed area of ​​the steel frame of the water storage tank is four sides , each of the four corners of the water storage steel frame is provided with a cable-stayed steel bar to reinforce the box body. The cross-sectional size of the cable-stayed steel bar is 5×5cm. The impermeable membrane covers the four sides and the bottom. The wire diameter of the barbed wire is 2mm, and the hole diameter is 5cm. On the rectangular steel pipe at the upper end of the steel frame of the water storage tank, 4 vertical rectangular support rods are set for each net cage to bind the upper outline of the net ca...

Abstract

The invention relates to the field of aquaculture, in particular to a finless eel aquaculture system and an aquaculture method in a greenhouse, and more particularly a method for carrying out high-density intensified culture on finless eels in a greenhouse by using a steel frame, impermeable membranes and a net cage. The finless eel aquaculture system comprises a water storage box, the net cage, a heat preservation greenhouse, a water inlet and outlet facility, a mini flow water facility, a sewage disposal facility, an oxygenation facility, aquatic plants and other facilities. The aquaculture method comprises the following three steps, namely finless eel larvae releasing, feeding and managing, and catching. The finless eel aquaculture system is arranged in the greenhouse on the ground, is not affected by geographic limitation and climate, has the capability of reducing the occupancy of aquatic water bodies, such as a pond in finless eel aquaculture and has the characteristics of conservation of land resources and culture water surface resources, detachability, high yield and high efficiency. The aquaculture system which is arranged in the greenhouse not only has the capability of alleviating the stress response of the finless eels caused by temperature difference, but also is conductive to releasing finless eel larvae in advance and prolonging the sale time of the finless eels in the market so as to increase the benefit.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a culture system and method for ricefield eels, in particular to a method for high-density and intensive cultivation of ricefield eels in a greenhouse by using steel frames, impermeable membranes and net cages. Background technique [0002] Yellow eel, scientific name Monopterus albus, also known as eel, long fish, etc., is a high-protein, low-fat, high-quality freshwater aquatic species with high nutritional value, and is very popular among consumers. Since the 1980s, my country has carried out artificial breeding of eels, and has formed a variety of models such as pond culture, paddy field culture, cage culture and cement pond culture. The physiological characteristics and reproductive habits of rice field eels are very special. At the first sexual maturity, the juvenile eels are all females, and the number of eggs is only a few hundred. Become a male eel and remain male for life. ...
