Problems solved by technology

However, in these open waters, when carrying out nutrient-intensive farming on these aquatic products, the applied nutrient-enriched fertilizers and feeds will be washed away by strong winds and waves. Therefore, how to weaken the strong winds and waves in the breeding area and seek better Fertilization method has become a key issue in aquaculture nutrition fortification
[0006] Patent CN2673090Y reports a combined pontoon for anti-wind and wave aquaculture cages. This pontoon adopts the structure of a floating frame surrounded by an integrally formed plastic hollow substrate with water exchange holes. The floating frame is integrally formed. The manufacturing process is not quite simple. The fine connection structure at its corners reduces the stability of its structure, and the side design of this floating tank has a small middle and two large double-cone water exchange holes. The shape is limited, and its specific size is not mentioned, and the design purpose of this water body exchange hole is to exchange water bodies inside and outside the aquaculture area. The problem of loss due to impact
[0007] However, the current aquaculture rafts, aquaculture net cages, and aquaculture net bags are all similar to the above-mentioned aquaculture floating tanks. Patent CN101617637A reports a kind of marine aquaculture net cage, and patent CN201409375Y reports a kind of marine aquaculture net cage fishing raft. , patent CN101822207B has reported a kind of construction method of kelp culture raft frame in deep-water high area, and patent CN101743917B has reported a kind of anti-current and anti-wave culture raft, and these patents have only introduced how to make culture net cage, culture raft firmer, more The method of wind and wave resistance, the existing technology can not effectively solve the problem of the erosion loss of nutrient-enhanced feed and fertilizer, which makes the nutrient-enhanced aquaculture more difficult

Embodiment 1

[0043]Choose a beach in the intertidal zone. When the tide is low, tidy up the beach a little so that the surface of the beach is flat, which is more convenient for the production of aquaculture rafts. The manufacturing method of the aquaculture raft of the present invention is: select the plank 1 most root that is 2 cm in thickness, select the wooden strip 4 most root that length surpasses 2 m, select the foam column 2 most that the diameter is 50 cm and according to Image 6 The cutting method is cut into multiple segments; every 4 segments of foam columns are arranged in a straight line, such as figure 2 and Figure 5 As shown, the chamfered faces of all foam columns 2 face the same side, and there is a space of 10 cm between adjacent foam columns 2. The wooden board 1 is horizontally placed on the foam columns 2, and the foam columns 2 and the foam columns are connected by ropes 6. Plank 1 fastened; as figure 2 and image 3 As shown, on the two sides of the board, tig...

Embodiment 2

[0046] Purchase kelp seedling curtains from Xiapu, Fujian, put the kelp seedling curtains in the seawater of Qifeng kelp farm in Fenghua City, Zhejiang Province, raise them temporarily for two months, and then pick the seedlings. Choose a 3.7-m-long brown rope to make the kelp rope. Two pieces of the kelp rope Tie a thin nylon rope on the end, and clamp the roots of the kelp seedlings into the kelp rope, and clamp 100 seedlings on each rope. Hang the thin nylon rope at both ends of the kelp rope into the opposite screw hook 3 in the culture raft described in Example 1 and adjust the water layer, and hang a kelp rope every 1 m; meanwhile, according to the same method, in the common The cultured kelp in the cultured raft is used as a common cultured raft group.

Embodiment 3

[0049] When the kelp was harvested, 3 kelp plants were randomly selected from the kelp rope of the common culture raft far away from the fertilization area as the non-iodine-enhanced control group of the common culture raft. The final determination of the biological iodine content of the kelp was 1083±120 mg / kg (dry weight) .

Abstract

The invention relates to an aquaculture raft. The aquaculture raft is a firm cultivation raft capable of floating under the water surface, which is built by materials, such as a fixing material layer (1), a floating material layer (2), a suspending device (3), a hanging arm (4), a fixing device (5), a rope (6), a connector (7) and the like. The aquaculture raft is used for culturing various aquatic products, and cultivates for a period of time through a method of applying fertilizer or feed to the cultured aquatic products so that the content of specific elements of the aquatic products is remarkably improved and an aquatic product culture effect of reinforcing the nutrition of the specific elements is reached. When the aquaculture raft disclosed by the invention is applied to aquaculture, a large amount of the fertilizer and the feed can be saved, and the aquaculture raft can be applied to cultivating aquatic products in rivers, lakes and seas, such as sea tangles, agars, fishes, shrimps, crabs, shellfishes, abalones, sea cucumbers and the like, is especially suitable for the aquaculture with reinforced biological nutrition and is also suitable for deepwater hypervariable regions with lack water nutritions, deep water, supercritical flow, large wind and large waves.

Description

technical field [0001] The invention relates to an aquaculture raft, which belongs to the technical field of aquaculture and biological nutrition enhancement. Background technique [0002] Currently, more than half of the world's population is undernourished, threatening their physical health, cognitive abilities, productivity and even survival. Deficiencies in protein, calcium, iron, zinc, selenium, iodine, vitamins and other nutrients have led to serious consequences in terms of human health, fertility, well-being and national development. According to UNICEF statistics, vitamin and mineral deficiencies Resulting death, disability and lost labor force have cost some countries more than five percent of their gross domestic product. With the gradual deepening of people's understanding of nutritional deficiency, nutritional fortification, as one of the main ways to control nutritional deficiency, has attracted more and more attention from all over the world. [0003] Biolog...
