Rice field eel pollution-free high-density tube farming device

Abstract

The invention discloses a rice field eel pollution-free high-density tube farming device which comprises a rice field eel tube farming pond or a net cage, wherein a cave nest is arranged in the rice field eel tube farming pond or net cage; the cave nest is formed by stacking tube nests; each tube nest is a PVC (polyvinyl chloride) tube or phyllostachys pubescens with the diameter of 3-4cm and the length of 0.8-1m; the holes at the two ends of the tube nest are polished to be smooth; the tube nests are vertically placed on two bamboo rafts or wood rafts flatwise; and 2-3 layers of tube nests are placed on every two bamboo rafts or wood rafts to form the cave nest. According to the invention, the rice field eel tube farming pond provides a relatively good stereoscopic cave-living environment, and the shortcomings of the existing common rice field eel ponds are overcome; the device disclosed by the invention can be popularized to all regions so as to realize pollution-free high-density farming of the rice field eel which is a high-quality aquatic product; and the water resources are saved to the greatest degree, and the increasing needs of consumers are met.

Description

technical field [0001] The invention relates to the aquaculture technology of rice field eel. Background technique [0002] Now, eel culture includes soilless culture and soil culture. Now it is mainly based on soilless culture. Soilless culture is divided into cage culture, plastic film culture, cement pond culture, plastic box culture and water tank culture. However, these models have different defects: such as cage culture is to culture rice field eels suspended in the water in the rice field eel culture cages, because the water in the box and the water outside the box are freely exchanged, but the cage culture is especially suitable for water-deficient areas. The northern region cannot be popularized and applied, and there are "large water surface, fish disease is easy to infect and difficult to disinfect; the mesh is easy to block. The existing artificial breeding of rice field eels mainly adopts the methods of hanging net cages, earthen ponds and cement ponds on the ...

Problems solved by technology

However, these models have different defects: such as cage culture is to culture rice field eels suspended in the water in the rice field eel culture cages, because the water in the box and the water outside the box are freely exchanged, but the cage culture is especially suitable for water-deficient areas. It cannot be popularized and applied in the northern region, and there are "large water surface, fish disease is easy to be infected and difficult to disinfect; mesh is easy to block

All methods also have many problems such as large water occupation, high bait coefficient, low output per unit area, short breeding cycle limited by seasons, heavy natural weight loss in winter, polluted water quality and high incidence of disease.

Therefore, it is impossible to achieve pollution-free high-density artificial breeding
