specific Embodiment approach

[0023] Taking the cultivation of salmon in the area with a water depth of 50m in the cold water mass of the Yellow Sea as an example, the specific implementation methods are as follows:

[0024] Such as figure 1 As shown, a compound net cage for deep sea fish culture consists of a fish culture cage 1, an energy platform 2, a column 3 connecting the fish culture cage 1 and the energy platform 2, and an anchoring system 4.

[0025] The fish cage 1 has a frame made of metal pipes, which are cylindrical or multi-faceted; fish are kept in the fish cage 1; there is a tubular column 5 in the middle of the fish cage, with a pipe diameter of 5m and a height of 30m , the bottom cover and the upper opening; the perimeter of the cage is 250m, and the netting 6 is 20m high; the netting is made of copper alloy wire or ultra-high molecular weight polyethylene fiber; the mesh size of the copper alloy wire mesh is 4-5cm, The specific specification depends on the specifications of the stocking...

Abstract

A compound net cage for deep-sea fish culture is characterized in that it includes a fish culture net cage, an energy platform capable of providing solar power generation, a pillar connecting the net cage and the energy platform, and an anchoring system. Under normal conditions, the fish cage is located in the upper layer of the water body; when a typhoon comes or the water temperature in the upper layer of the sea is too high for the season of fish farming or the need for disease prevention, the fish cage is sunk to a specific water layer or the bottom of the water body through the platform lifting device; When fishing or drying nets, the fish cage can be partly or completely exposed to the sea surface. The invention can overcome the disadvantages of the current cages, and has the advantages of avoiding typhoons, cultivating cold-water fish in summer, preventing fish lice infestation, green energy, automatic baiting, preventing shark attacks, easy fishing, easy cleaning of attached organisms, and occupying sea area The advantages of small size and low cost are more suitable for the application and promotion of aquaculture in deep and open seas.

Description

technical field [0001] The invention belongs to the field of aquaculture and marine resource development, and in particular relates to a composite net cage for deep sea fish culture, which is used to support the expansion of seawater fish net cage culture to deep sea. Background technique [0002] Large-scale mariculture is concentrated in a narrow space in shallow waters near the coast, which has brought about a series of problems such as industrial conflicts, ecological losses, disease risks, and quality and safety. Therefore, it has become an inevitable choice for the development of my country's mariculture industry to expand mariculture from nearshore to offshore and to deep sea. [0003] In order to meet the needs of offshore farming, some units at home and abroad have successively developed high-density polyethylene (HDPE) circular floating deep-water cages, lifting circular cages, and dish-shaped deep-water cages. In recent years, my country has also successfully dev...
