Embodiment Construction

[0048] The specific implementation manners of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0049] A simple and efficient ecological interculture cage, the main schematic diagram of the cage is as follows figure 1 As shown, the interior floor plan is as figure 2 shown. Including the upper and lower culture units, the multi-functional drainage system in the middle and the placement place 5 of the sea urchin carcass area. Each culture unit includes two layers of structure: the upper sea urchin area and the lower sea cucumber area, each culture unit is 150 cm long, 80 cm wide, and 38 cm high; The feces produced by sea urchins are separated by a polyethylene net of 2.5mm, and the feces produced by the sea urchins fall to the sea cucumber area through the mesh holes of the polyethylene net as bait for young ginseng. The sea urchin area and the sea cucumber area alternately form a relatively indep...

Abstract

The invention discloses an ecological intercropping net cage for precious marine products and belongs to the field of aquaculture. The ecological intercropping net cage comprises an upper-layer culture unit, a lower-layer culture unit, a multifunctional drainage system in the middle and a matched device, wherein the culture units are vertically distributed in a net cage purse net; each culture unit comprises an upper-layer sea urchin area and a lower-layer sea cucumber area, and the sea urchin areas and the sea cucumber areas are alternately arranged two by two to form a relatively independent intercropping system; and the upper-layer sea urchin areas and the lower-layer sea cucumber areas are separated by polyethylene nets with meshes, and excrement generated by sea urchin falls into the sea cucumber areas from the meshes to serve as young sea cucumber bait. The multifunctional drainage system is located in the middle of the net cage surrounding net, penetrates through the whole culture net cage, and is used for feeding baits in the sea urchin areas and cleaning sea urchin excrement which is not eaten up by sea cucumbers, excrement generated by the sea cucumbers and other metabolites in the sea cucumber areas. The problems of sea urchin winter ingestion and excrement cleaning can be solved, and winter growth of sea cucumbers is facilitated; and the ecological intercropping net cage uses common culture materials, is low in price, simple and time-saving to operate, capable of realizing large-scale intensive production and suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to equipment for cultivating sea treasures, in particular to a simple and efficient ecological nesting cage for sea treasure seedlings. Background technique [0002] With the improvement of people's living standards, the demand for sea treasures is also increasing. Taking sea urchin and japonicus as examples, my country's 2019 output is about 171,700 tons and 8,242 tons respectively, but it still faces a sharp contradiction of short supply. Low-efficiency seedling intermediate cultivation is the most serious bottleneck restricting its industrial development. [0003] For the sea urchin industry, sea urchin seedlings produced in the north need to be cultivated indoors in winter. The heating cost of this process is high, and the growth effect of sea urchin seedlings is not ideal, and the proportion of class I seedlings (shell diameter> 1cm) is low. As far as the sea cucumber industry is...
