Problems solved by technology

However, too many aquatic plants will consume a lot of oxygen in the water at night in the high temperature season, and cause the eel to die due to lack of oxygen. At the same time, the rotten aquatic plants will also deteriorate the water quality and cause diseases.
Production practice shows that only planting aquatic plants cannot solve the problem of low production of ricefield eels, because aquatic plants have no significant effect on separating living space and improving the survival rate of ricefield eels
Because of the existence of the above-mentioned many problems in the eel breeding process, the current eel farming output has been hovering at a low level.

Embodiment 1

[0021] The present invention is a method for improving ricefield eel breeding yield by utilizing layered concealment, and adopts the following breeding steps:

[0022] (1) The composition of the layered concealment:

[0023] The laminated concealment is formed by connecting the mesh 2 and the concealment frame 1. The mesh 2 is 2.0m long and 1.5m wide, and the concealment frame 1 is formed by connecting frame steel bars. The diameter of the frame steel bars is 10mm.

[0024] The mesh of the mesh is 0.8 cm. The stacked concealment is 1.0m high and can be divided into 5 layers with a layer height of 20cm. Each layer is supported by a support steel bar 4 with a diameter of 6mm, and a vertical partition 3 is set. The mesh of the partition 3 is 0.5cm . The net sheet 2 of concealment bottom is 10cm apart from the distance at the bottom of the pool.

[0025] (2) Breeding method:

[0026] Put the concealed object in the eel breeding pond, place 10 per mu of water surface, the conce...

Embodiment 2

[0028] The present invention is a method for improving ricefield eel breeding yield by utilizing layered concealment, and adopts the following breeding steps:

[0029] (1) The composition of the layered concealment:

[0030] The laminated concealment is composed of mesh 2 and concealment frame 1. The length of the mesh is 1.5m and the width is 1.0m. The concealment frame 1 is formed by connecting frame steel bars. cm. The stacked concealment is 1.2m high and can be divided into 6 layers with a layer height of 20cm. Each layer is supported by a supporting steel bar 4 with a diameter of 6mm, and an oblique partition 3 is set. The mesh of the partition 3 is 0.5 cm. The net sheet 2 of concealment bottom is 10cm apart from the distance at the bottom of the pool.

[0031] (2) Breeding method:

[0032] Put the concealed object in the rice field eel breeding pond, place 20 per mu of water surface, the hidden objects sink in the water, the uppermost layer is 0.3m away from the wate...

Embodiment 3

[0034] The present invention is a method for improving ricefield eel breeding yield by utilizing layered concealment, and adopts the following breeding steps:

[0035] (1) The composition of the layered concealment:

[0036] The laminated concealment is composed of mesh 2 and concealment frame 1. The length of the mesh is 2.5m and the width is 1.2m. The concealment frame 1 is formed by the connection of frame steel bars. cm. The height of the stacked concealment is 1.5m, which can be divided into 5 layers with a layer height of 30cm. The average diameter of each layer is supported by 6mm supporting steel bars 4, and an oblique partition 3 is set. The mesh of the partition 3 is 0.5cm . The net sheet 2 on the bottom of the concealment is 20cm away from the bottom of the pool.

Abstract

The invention relates to a method for improving ricefield eel culture production by utilizing a stacked hidden object, which is characterized by comprising the following culture steps of (1) constitution of the stacked hidden object: connecting net pieces and hidden object frames to form the stacked hidden object, connecting frame reinforcing steel bars to form the hidden object frames, and dividing the stacked hidden objects into three to ten layers which are in supporting connection through supporting reinforcing steel bars and are provided with partition nets; (2) a culture method: placing the stacked hidden object into a ricefield eel culture pond; and (3) planting water hyacinth, alternanthera philoxeroides and waterweeds with coverage rate accounting for 60% of the pond area in the ricefield eel culture pond so that ricefield eel can dwell in the stacked hidden object in a layered mode to improve culture density. The method is low in cost, convenient in use and capable of providing relatively independent micro-habitats for the ricefield eel, greatly reducing rate of cannibalization of the ricefield eel and improving culture survival rate, culture production and benefits.

Description

technical field [0001] The invention relates to a method for cultivating ricefield eels, in particular to a method for cultivating ricefield eels by using concealed objects in a pond. Background technique [0002] Rice field eel is a kind of aquatic product that is popular among Chinese consumers. Although the area of ​​rice field eel breeding in my country has continued to increase in recent years, the output has not been able to increase significantly. In addition to the bottleneck problem in seed supply, the reason for the low yield of artificially cultured eels is also one of the important reasons for the high rate of self-mutilation and morbidity during the breeding process. At present, there are mainly three methods of artificial cultivation of ricefield eels: pond cultivation, paddy field cultivation and net cage cultivation. In the cultivation process of different cultivation modes, aquatic plants need to be planted to shade the sun, so that the water temperature of...
