Embodiment 1

[0030] Such as figure 1 As shown, the single-ringed weed indoor cultivation device adopted in the present embodiment includes a cultivation pond 1, a cultivation box 2, a brick body 3, a microporous inflatable pipe 4, and an overflow pipe 5. The bottom of the cultivation pond 1 is provided with matrix-shaped A plurality of brick bodies 3, the specification of cultivating pool is 6m * 3m * 1m in the present embodiment; Lay microporous gas-filled tube 4 between adjacent two rows of brick bodies 3, the diameter of micro-porous gas-filled tube 4 in the present embodiment is 16-25mm, preferably 20mm, a row of micropores is evenly arranged along the direction of the microporous inflatable tube 4 pipe walls, the interval between every two micropores is 5-15cm, preferably 8-10mm, the diameter of the micropores is 1mm, and at least one Microporous inflatable tube 4, 6 microporous inflatable tubes are laid in the present embodiment; Breeding box 2 is placed on the brick body 3, and the ...

Embodiment 2

[0037] What the culturing method in the present embodiment adopted was the cultivating device that embodiment 1 provided, and concrete cultivating method is as follows:

[0038] Step 1, seedling cultivation:

[0039] From April to May every year, we select the broods of Echinococcus monoringensis from the natural sea area, and promote maturation in the nursery room for 3-5 days to obtain mature eggs. After fertilization and hatching, they develop into trochophore larvae, and the larvae are cultivated for 15-20 days to inhabit Dive into the sand and metamorphose into juveniles. After 35-40 days of cultivation, the juveniles will grow into seedlings with a body length of 1-1.5cm.

[0040] In the cultivation process of the present invention, the parent bodies in mid-April, the mature eggs obtained in the seedling cultivation room for 4 days, the larvae formed after 18 days of cultivation, and the seedlings of 1 cm grown in 38 days were selected.

[0041] Step 2, cast seedlings: ...

Abstract

The invention belongs to the field of aquatic livestock breeding, and particularly relates to an indoor breeding device and method for urechis unicinctus. The breeding device comprises a breeding pond, breeding boxes, bricks, microporous inflation pipes and a water overflow pipe. The bricks are arranged at the bottom of the breeding pond in a matrix shape, each microporous inflation pipe is laid between the two adjacent rows of bricks, the breeding boxes with a plurality of round holes are placed on the bricks, net boxes, grait and screen meshes are sequentially laid on the bottoms of the boxes, and the water overflow pipe is arranged at the bottom of the breeding pond. The breeding method comprises the steps that 1, fry are bred; 2 the fry are fed; 3, in the breeding stage, feeding, water change and temperature controlling are carried out; 4, box shifting and fry screening are carried out; 5, the fry are developed. The bricks are adopted as supporting bodies, the breeding boxes are adopted as carriers, inflation equipment is laid on the bottom of the pond, organic matter in the breeding device is discharged out, local pollution is avoided, the living environment of the urechis unicinctus is improved, the indoor breeding sand changing and pond shifting time is prolonged, the breeding yield is improved, and labor cost is lowered.

Description

technical field [0001] The invention belongs to the field of aquatic animal breeding, and in particular relates to an indoor culturing device and method for the single-ringed weed. technical background [0002] Commonly known as "sea intestines", the single-ringed spinyweed is a common species in the benthic populations along the coasts of the Yellow Sea and the Bohai Sea. The single-ringed spiny spiny is fat and delicious, and its body wall muscles are rich in protein and a variety of essential amino acids. The coastal areas of China, Japan and South Korea are all regarded as famous and precious seafood, and have relatively high economic value. Due to the excessive fishing intensity in recent years, the resources of E. monoringensis have declined sharply, so the work of artificial breeding and breeding has begun to be paid attention to. [0003] Through the technological research in recent years, the artificial seedling raising technology of Echinococcus monoringensis has ...
