Description
Technical Field
The invention belongs to the field of wind power cultivation, and particularly relates to a seawater net cage structure of a marine single-pile foundation wind power column and a cultivation operation method.
Background
Seawater cage culture has been popularized in China coastal areas for many years, and at present, the main culture modes comprise a traditional wood plate frame type cage and an HDPE floating cage. Generally, 1-port wood plate frame is 4m long and 4m wide, a plurality of frames are connected together to be called a fish raft, and a 4 x 4m net cage net is hung in conventional cultivation, so that the fish raft can be cultivated in a shallow sea area with the water depth of about 5 m. The HDPE full floating net cage is more circular and also square, and the perimeter of 1 port is generally more than 40 m. The HDPE full-floating net cage is suitable for sea areas with water depth of more than 10 meters, and is also called as a deep-water net cage.
The HDPE full-floating net cage is suitable for hanging a net coat with a large net to culture large commercial fishes, the wood plate frame type net cage is suitable for culturing fish fries, and when 1 large net cage is hung under a multi-port net cage frame, the HDPE full-floating net cage is also suitable for culturing large commercial fishes (1 port of the net cage hung by the 1 port of the frame is called a system 1, 2 ports of the net cage hung by the 2 port of the frame is called a system 2, and so on). In the seawater net cage culture industry, it is acknowledged that the growth speed, feed coefficient and quality (strip shape and taste) of commercial fish are obviously superior to those of the commercial fish cultured in small net cages when the large net cages (4-system net cages with at least more than 4 openings combined by wood frames or HDPE floating net cages with more than 40m of perimeter) are used for culturing edible seawater commercial fish.
When the net is soaked in seawater for a long time in cage culture, a large amount of marine fouling organisms can be attached and grow, and about 650 types of marine fouling organisms are recorded along the coast of China. These species belong to the major phyla of marine fungi, algae and marine animals, respectively. The marine algae mainly comprise diatom, enteromorpha, ulva and the like. The marine animals include oyster, barnacle, sea anemone, sea squirt, etc. After a large amount of fouling organisms are attached to the fish culture net, the net meshes can be blocked, oysters and barnacles are attached to the net to directly scratch the body surfaces of commercial fish cultured in the fish culture net, and sea anemones can secrete toxins when touching the body surfaces of the fish to corrode the fish. The method has the advantages that a large amount of attached fouling organisms seriously affect the fish culture of the net cages, the fish to be cultured must be cleaned regularly, the wood frame net cage culture generally needs to be cleaned for 1 time in half a month in spring, summer and autumn with high water temperature, and the cleaning of the fouling organisms attached to the net cage is one of important work and labor cost of daily management of the seawater net cage culture.
Patent No. CN201710304668.9 discloses a land-based integrated assembly method of an offshore wind power coupling culture device, which provides a culture method but cannot be used for net drying, and the culture efficiency is low after long-term use.
