Description
Technical Field
The invention relates to the technical field of ecological breeding, in particular to a seaweed breeding device combined with a floating-sinking type breeding net cage and a using method thereof.
Background
The seaweed is not only a regulator of marine environment, but also a high-quality bait for precious marine products (such as sea cucumber, abalone, sea urchin and the like). At present, the main seaweed culture varieties in China mainly comprise: kelp (Laminaria japonica), Gracilaria (Gracilaria), Undaria (Undaria), laver (Pyropia) and the like, the cultivation of these kinds of seaweeds is mainly concentrated in shallow sea areas within a deep line of 20 meters and the like, and offshore deepwater cultivation of seaweeds has not been effectively developed due to the reasons of cost, technology, risk and the like.
At present, the kelp, the gracilaria and the undaria are cultured by adopting a traditional raft culture mode basically, namely a pile driver piles a muddy sea bed as a fixing mode, and a root rope connects a frame rope (or a floating rope) with a root pile on the sea bed. And tying the seedling ropes of the kelp or the undaria pinnatifida to the rack ropes or the floating ropes at certain intervals. The cultivation mode can only be applied to offshore and gulf waters, and in recent years, the environment of the offshore water area deteriorates year by year due to high-density and overload offshore cultivation, various diseases frequently occur, and the cultivation yield and quality are greatly reduced.
In the prior art, some patent inventions aiming at cultivating seaweed in a deep water area are provided, for example, Chinese patent with publication number CN101822207A discloses a construction method of a deep water high-area laminaria culture raft frame, the method only increases the fixation of deepening roots according to the characteristics of the deep water area and adopts a fixing mode of a thick root rope, but the scheme is difficult to fix because the deep water area is located offshore (the water depth exceeds 20 meters), and the offshore deep water area (the water depth exceeds 20 meters) often has large waves, so that the seaweed cultivation is easily lost once the deep water area is not firmly fixed.
Compared with the traditional aquaculture net cage, the offshore deep-water floating type large aquaculture net cage for aquaculture of marine economic animals (fishes, precious marine products and the like) has the advantages of strong wind and wave resistance, wide application sea area and the like, so the offshore deep-water floating type large aquaculture net cage is gradually popularized and used in offshore deep-water areas (the water depth exceeds 20 meters), and better economic benefit can be generated if the offshore deep-water floating type aquaculture net cage can be combined with seaweed aquaculture.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-2, the invention comprises a sinking and floating culture net cage 5 and a flexible culture raft frame, wherein the flexible culture raft frame comprises a first floating rope 1 and a second floating rope 2 which are parallel to each other, the second floating rope 2 is arranged between the first floating ropes 1, a plurality of hooks 6 are arranged on the lower side of the first floating rope 1 at equal intervals, a plurality of floating balls 3 are arranged on the upper side of the first floating rope 2 at equal intervals, a plurality of floating balls 3 are arranged on the upper side of the second floating rope 2 at equal intervals, two ends of the seaweed seedling rope 7 are respectively fixed on the hooks 6 corresponding to the first floating ropes 1 on two sides, the seaweed seedling rope 7 is supported and kept on the same culture water layer through the middle second floating rope 2, chains 4 are arranged at two ends of the first floating rope 1 and the second floating rope 2, a chain hook 8 is arranged at the free end of the chain 4, as shown in fig. 1, one end of the flexible culture net cage 5 is fixed on the floating net cage 5, and two ends of the first floating rope 1 and the second floating rope 2 are wound on the floating rope 5 At the edge, the chain hook 8 at the free end of the chain 4 bypasses the edge of the upper end of the floating aquaculture net cage 5 and then hooks any chain hole on the chain 4 to realize binding, and a fixed rope 9 is connected at the joint of the first floating rope 1 and the chain 4, as shown in fig. 1, the other end of the fixed rope 9 is bound with a seabed fixed seat below the floating aquaculture net cage 5 to resist the larger sea current in the offshore deep water area. The ups and downs type culture net cages 5 realize ups and downs through inflation and deflation, and the ups and downs type culture net cages 5 are well known in the art.
In this embodiment, the first floating boom 1 and the second floating boom 2 are made of polyethylene or polypropylene ropes, each floating boom has a length of 60 to 100 meters, the three floating booms are arranged in parallel at equal intervals, the distance between every two floating booms is 3 to 4 meters, the length of the chain 4 is 10 to 15 meters, the distance between the hooks 6 on the first floating boom 1 is 0.6 to 0.9 meter, the distance between the floating balls 3 on the first floating boom 1 and the second floating boom 2 is 5 to 7 meters, and the floating ball 3 is used for adjusting cultivation, so that safe production can be ensured when a large wind wave occurs, and meanwhile, the light energy utilization efficiency of the sea belts and the like can be improved to the maximum extent, and the yield of the kelp can be improved.
The two ends of the seaweed seedling rope 7 are knotted into a ring shape, so that the seaweed seedling rope can be directly hung on the hook 6, and the seaweed seedling rope is different from a traditional seedling rope with two ends tied on a floating boom, so that the labor intensity is greatly reduced, and the labor efficiency is improved.
The working principle of the invention is as follows:
1) seedling picking and temporary culture of seaweed seedlings: and (4) cutting the seedling curtain with the attached seedlings into rope sections with the length of 50 cm, temporarily culturing in the sea area, and starting seedling separation after temporarily culturing for 20-30 days.
2) Separating the seedlings to obtain the kelp seedling cultivation ropes: when the kelp seedlings grow to be more than 15 cm-20 cm, the seedling separation culture is carried out batch by batch in a mode of separating large seedlings from small seedlings, and the handle parts of the seedlings meeting the seedling separation specification are clamped on the culture ropes to obtain the seaweed seedling ropes 7.
3) The seaweed seedling rope 7 is used for carrying out the flat culture in the offshore deep water area: two ends of the seaweed seedling rope 7 with the length of about 6-8 m are knotted into a ring shape and then are distributed and hung on the hooks 6 on the two first floating ropes 1 on the outer side, and the seaweed seedling rope 7 is supported by the middle second floating rope 2, so that seedlings on the seaweed seedling rope 7 can be on the same cultivation water layer even in the later cultivation period.
4) Adjusting a culture water layer: in the cultivation process, the cultivation water layer needs to be adjusted according to the conditions of seawater transparency change, precipitation, algae weight increase and the like. The regulation of the culture water layer can be realized by hooking the chain hooks 8 at the free ends of the chains 4 in different chain holes on the chains 4, and the culture water layer can be regulated by lifting the floating culture net cage 5 or by combining the lifting and the regulating to ensure the regulation accuracy. When meeting large storms, the whole flexible culture raft frame can be sunk to a certain depth under water through the floating culture net cages 5 so as to avoid loss.
5) Harvesting the kelp: when the kelp can be harvested after the kelp is cultured, the seaweed seedling rope 7 only needs to be taken down from the hook 6 on the first floating boom 1 instead of the conventional manner of opening the knot or cutting the knot with a knife, so that time and labor are saved and materials are saved.
