Problems solved by technology

The advantage of bottom-seeding multiplication in sea areas is that the breeding environment is a natural environment, the bait required by sea cucumbers is abundant, and the growth rate is fast. The disadvantage is that the ability to resist natural disasters is weak, and the survival rate and harvest rate of sea cucumbers are low, and the harvest rate is generally below 5%. The advantages of building ponds on rocky reefs in the intertidal zone are large water changes, the breeding environment is close to the natural environment, and the survival rate can reach more than 50%. The disadvantage is that it occupies a large amount of intertidal sea area and seriously damages the natural landscape. Therefore, it cannot meet the needs of sea cucumber culture; the advantage of pond culture is th

Embodiment Construction

[0014] Describe concrete structure and using method of the present invention in detail below by example:

[0015] 1. Structural content:

[0016] The separated japonicus breeding net cage is rectangular, and its structure is made of frame 5, net sheet 4 and net bag 6. Frame 5 is made of Φ2cm PVC plastic pipe, which is 0.75m in height, 1m in length and 1m in width, and bonded by elbows, tees, glue, etc. Cut into equal mesh pieces with a size of ×1m, and hang them vertically and evenly in the frame 5 with a 65° slope. space. Mesh bag 6 is the polyethylene knotless net of mesh 0.8cm, is made into tubular shape by the size of long 2.5m, circumference length 3.5m, and is overcoated on the frame 5. After the ginseng seedlings are put into it, the net bag 6 two ends use nylon rope to seal firmly.

[0017] 2. How to use:

[0018] Use 360 ​​plied nylon rope to make the floating rope 2, the two ends of the floating rope 2 are fixed on both sides of the pool dam by wooden stakes, an...

Abstract

The Stichopus japonicus cultivating separate mesh cage apparatus has the structure comprising a frame, mesh sheets and mesh bags. The frame is made of PVC pipes connected with elbows and T-pieces; the mesh sheets are hung inside the frame; and the mesh bags made of polyethylene net are cylinders around the frame and have ends tied with nylon ropes. The separate mesh cage apparatus provides closed Stichopus japonicus growing space without effects of harmful environment factors and enemy organism invasion, and has high Stichopus japonicus survival rate and yield.

Description

Technical field: [0001] The invention belongs to the aquaculture technology, and relates to a separated sea cucumber cultivation device in net cages. Background technique: [0002] At present, the scale of japonicus farming in northern my country is expanding day by day, and the farming method has also changed from bottom seeding and multiplication in the sea area to building ponds on intertidal rocks and reefs, and then pond farming in the transformation of shrimp ponds. The advantage of bottom-seeding multiplication in sea areas is that the breeding environment is a natural environment, the bait required by sea cucumbers is abundant, and the growth rate is fast. The disadvantage is that the ability to resist natural disasters is weak, and the survival rate and harvest rate of sea cucumbers are low, and the harvest rate is generally below 5%. The advantages of building ponds on rocky reefs in the intertidal zone are large water changes, the breeding environment is close to ...
