Embodiment Construction

[0024] Attached below figure 1 ~ attached Figure 4 The present invention is described in detail below.

[0025] Such as Figure 1~4 Shown, the present invention comprises three-dimensional support 1, two layers of cultivation areas are set on the top of three-dimensional support 1, are respectively the scallop cultivation area 2 of the upper floor and the sea cucumber cultivation area 3 of the lower floor, and nets are used around each layer of the cultivation area. Surrounded by clothes 4;

[0026] Eight standing vertical nets 5 are fixed between the opposite two side nets of the Ezo scallop culture area 2, and eight three-dimensional net pockets 6 are arranged on each longitudinal net 5, a total of 64, and the material of the three-dimensional net pockets 6 is usually The used net clothes of scallop cultivation net cage, the size of net bag 6 is 20cm * 10.5cm. The three-dimensional net bag 6 can prevent the scallops from colliding and biting each other due to the non-se...

Abstract

The invention relates to the technical field of aquaculture, specifically to a mixed culture system for sea cucumber, shrimp and shellfish based on a deep-water net cage. The mixed culture system of the invention comprises a stereo bracket, wherein the upper part of the stereo bracket is provided with at least two layers of culture areas; the periphery of each layer of the culture area is surrounded with a netting; the bottom layer of the culture area is used for the culture of the sea cucumber; a plurality of sea cucumber blindages are fixedly arranged on the netting of the bottom layer of the culture area; other layers of the culture areas are used for culture of Patinopecten yessoensis; a plurality of longitudinal nettings are fixedly arranged between the nettings at two opposite side surfaces of the Patinopecten yessoensis culture areas; and a plurality of stereo string bags are arranged on each longitudinal netting. The mixed culture system provided by the invention is designed according to biological and ecological characteristics of the Patinopecten yessoensis and the sea cumber, can promote growth of the sea cucumber and improve culture yield per unit of the Patinopecten yessoensis, has the characteristics of simple operation and strong on-site operability and can improve culture yield and reduce environmental pressure by making full use of maritime space and complementarity of ecological niches of different varieties.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a deep-water cage-based ginseng, shrimp and shellfish mixed culture system. Background technique [0002] Apostichopus japonicus is one of the precious species of marine economic animals in my country, and it feeds on seabed sediments scraped or swept by tentacles. Sea cucumber is not only a delicacy and health food, but also a marine drug with high medicinal value. With the development of social economy and the improvement of people's living standards, the demand for this era is increasing. [0003] Ezo scallop belongs to cold-water shellfish, which has the advantages of large individual, fast growth and high economic benefit. Since it was introduced into my country in the 1980s, after years of technical research and research, breakthroughs have been made in artificial breeding and breeding technology, and it has been cultivated on a large scale in Liaoning, Shandong and o...
