Embodiment 1

[0034] Use a small excavator to dig an earthen pond with a length of 6m, a width of 5m, and a height of 55cm, and compact the bottom, ridge and inner wall of the pond to make it smooth and tidy. , width 7m), after drainpipes and overflow pipes (60cm long polyvinyl chloride pipes) are set, an open polyethylene no-nodule net cage is placed, and the net cage is 4m long, 3m wide, 100cm high, and has a mesh of 30 meshes. Put 30 willow branches in the net cage, each branch has a diameter of 6-10mm and a length of 60cm, so that it grows willow roots in the water; simultaneously put 6kg of fresh Polygonum hydroponica and 10kg of water peanuts. Then, put in 8kg of apple snails and 6kg of water spinach in the open space between the cage and the inner wall of the pond, and add 25cm of water for cultivation to a depth of a kind of eel ecological cultivation pond.

[0035] The cost of building the pool is 840 yuan, including 560 yuan for anti-seepage membrane, 150 yuan for labor, 90 yuan f...

Embodiment 2

[0037]Manually dig an earthen pond with a length of 5m, a width of 4m, and a height of 60cm, tamp the bottom, ridge and inner wall of the pond to make it smooth and tidy, and lay a high-density polyethylene impermeable membrane (thickness 0.4mm, length 6m, width 5m), set After the drain pipe and the overflow pipe (60cm long polyvinyl chloride pipe), place an open polyethylene no-nodule net cage with a length of 3m, a width of 3m, a height of 90cm, and a mesh of 40 meshes. Put into 20 willow branches in the net cage, every branch diameter 10mm, length 70cm, make it grow willow root hair in water; Meanwhile, put into fresh Polygonum hydroponica 5kg and water peanut 8kg. Then, put 6kg of apple snails and 5kg of water spinach in the open space between the net cage and the inner wall of the pond, and add 30cm of breeding water to build a kind of rice field eel ecological breeding pond.

[0038] In this example, the pool construction cost is 550 yuan, including 320 yuan for anti-see...

Abstract

The invention belongs to the field of aquaculture, and in particular relates to a building method of a ricefield eel ecological culture pond. The method comprises the following steps of: digging a earth pond, spreading impermeable membranes on the walls and the bottom of the pond; arranging a draining pipe in the pond and placing a ricefield eel culture net box; putting willow branches, fresh polygonum hydropipers and alternanthera philoxeroides in the net box; putting ampullaria gigas and water spinaches into vacant places between the net box and the inner walls of the pond; and adding culture water to build the ricefield eel ecological culture pond. The ricefield eel ecological culture pond has the characteristics of low building cost and long service life, escape prevention of ricefield eels, reasonable water level control, effective regulation of water quality, prevention of ricefield eel disease and insect pests, convenient management, improvement of the overall performance of the ricefield eel culture, and the like.

Description

(1) Technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for constructing an ecological breeding pond for rice field eels. (2) Background technology [0002] From the perspective of farming methods, eel farming includes soilless farming, soil farming and mixed farming (that is, some with soil and some without soil). Due to the low cost of building ponds for soilless aquaculture, the eel is easy to catch, the breeding density is high, the output is high, and the benefit is good, so soilless aquaculture is the main method of production. [0003] According to the materials, soilless culture can be divided into cage culture, plastic film culture, cement pond culture, plastic box culture and water tank culture. However, these models have different defects: for example, the cage culture is to raise the rice field eel in the rice field eel culture cage suspended in the water, and the dissolved oxygen in the cage ...
