Although there is a huge demand for kelp as food, its main production is still left to natural collection. On the other hand, amidst the remarkable depletion of fisheries resources in recent years, cultivation and breeding of fisheries have been strongly promoted. In business, there is a rapid shift to aquaculture methods with higher catch productivity, and recently, large-scale aquaculture projects for rock-based seafood such as abalone, sea urchins, and turban shells are being planned in various locations. .

However, rockfish such as abalone, sea urchin, and turban shell live in rocky reef areas, and grow primarily on brown algae such as kelp, kajime, arame, and wakame, which grow on the reefs. Coastal sea areas, which are the breeding areas for species, have become extremely polluted or enriched with wastewater from factories and households.
Furthermore, the ecosystem changes due to changes in tidal currents due to port construction and coastal civil engineering work, and certain algae and aquatic animals, especially stubble calcareous algae and colonial sea urchins, breed abnormally, causing damage to the entire reef surface. The phenomenon of rock burning, which inhibits the attachment and growth of zoospores of brown algae, is rapidly expanding. Brown algae are also in dire need, and in order to maintain and expand the Isotsuke seafood aquaculture business, there is a strong desire to increase and cultivate brown algae.

Therefore, at present, as shown in Figure 1,
Main net A is a twisted rope made of synthetic fiber material, etc.
Then, the seed yarn B obtained by collecting young brown algae seedlings is wound around the trunk net A, or the seed yarn B is tied at appropriate intervals, or the seed yarn pieces B' cut into short pieces at appropriate intervals are held. This is spread out in the form of a long line at a depth of about 1 to 5 meters below the sea surface to increase the culture, but brown algae grow to relatively large sizes, especially kelp, which is 2 to 10 meters deep.
As the main net A grows, it not only increases the tidal current resistance, but also because the trunk net A is spread out in relatively shallow water, it not only has wave resistance in normal times, but also strong wave resistance in stormy weather. It will be added. Therefore, in order for brown algae to grow against the current resistance and wave resistance, its rhizoids must be firmly attached to the trunk net A, but the trunk net A is simply a twisted rope. Since the rhizoids are not intertwined or intertwined, and the cross section is approximately circular, they are only attached by wrapping along the outer circumferential surface. It is relatively smooth except for slight twisting depressions, and especially when synthetic fiber materials are used, the material's slipperiness and mold release properties make it easy to slide. As the brown algae grows, when strong tidal current resistance or wave resistance is applied, the rhizoids detach from the main net A and slide, and these repeated resistances further increase the sliding and cause them to separate from the main net A and become washed away. The production yield is very poor, and even those that have survived the shearing process are severely damaged by repeated sliding after peeling and sliding, and their rhizoids are severely damaged and their growth is inhibited. Because the species move unevenly to arbitrary positions on the trunk net A, even when the entire trunk net A is settled to the reef surface to feed the rocky fish and shellfish that live in the rocky reef area, There are major problems with the current brown algae cultivation ropes, such as the inability to feed fish and shellfish evenly.

The present invention was made in view of this problem, and the present invention involves knitting a knotted or knotless net-like material with a number of stitches within 1 to 10 stitches, and in which the net yarns related to the knitting are twisted in the first twist. The number of ply twists is 1.0 to 3.0 times the number of ply twists, and as the tension is released after knitting, the untwisting force of the highly twisted ply twists of the net threads is used to tightly converge the net in a spiral manner to form a net structure. By using this rope, it is possible to firmly fix the rhizoids and prevent them from sliding, increasing the production yield of brown algae, achieving uniform fixed growth, and evenly feeding fish and shellfish on the shore. The invention consists in a mesh rope for cultivating algae that can be fed.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 2 is a sketch of a knotted net, FIG. 3 is a sketch of a knotless net, FIG. Fig. 5 is an explanatory diagram of the present invention using a knotted net-like material, and Fig. 6 is a diagram of the same usage mode. There is no limit, but since it is necessary to use the pre-twisting and untwisting force of the net threads 2 after knitting to tightly converge the threads, it is not appropriate to have a wide width of the so-called net-like material 1 with too many stitches. It is preferable to limit the number of multiplications within the following range. The mesh sizes 10A and 10B of the net-like material 1 are determined in various ways depending on the diameter of the mesh thread 2 used, the size of the brown algae to be grown, the growth density, etc.; It is something that grows, but 10~
If the net yarn 2 itself is to be grown to a weight of 20 kg, it must have sufficient toughness, so its diameter should be 5 to 10 mmφ.
The mesh size is 10A, 10B.
It is also preferable that the fibers are knitted to a length of about 100 to 300 cm.

When knitting the knotted net-like material 1A or the knotless net-like material 1B, the mesh threads 2 forming the mesh are
is the so-called triple twisted net yarn 2A or strand 20 made by twisting three strands of each strand 20A.
It may be knitted using either of the so-called twin-twist net yarns 2B, which are made by twisting two A strands, but the number of ply twists given to the strand 20A itself per unit length is two. Or when three threads are twisted together to form net thread 2, the number of twists is 1.0
It is important that the twist is strongly twisted within the range of ~3.0 times. In other words, the net yarns used in normal net knitting are designed so that the repulsive forces (untwisting forces) of the first twist and final twist are balanced with each other so that the net yarns themselves are free from deformation or kinking. For example, in the case of a net yarn with a diameter of 6 mmφ, the strand diameter is 3 when the configuration is a triple twist.
mmφ is used, and when twin-twisted, the strand diameter is approximately 4.2 mmφ,
In such a case, the relationship between the first twist and the first twist is that in triple twist, when the number of first twists is 200 per 1 m, the number of first twists is approximately 100, and in double twist, when the number of first twists is 170 to 180 per 1 m. The number of first twists is said to be approximately 100 times in terms of balance, and in summary, the ratio of the number of first twists to the number of first twists is approximately 0.5 times for triple twists and approximately 0.55 to 0.6 times for double twists. hand,
From this, it is understood that the number of twists of the net yarn 2 in the present invention is extremely high. The strongly twisted ply twist of the net yarn 2 exerts an untwisting force as the tension is released after knitting, but in the relationship between the number of first twists and the number of final twists of the net yarn 2, the strand 20A is formed. If the fiber to be used is a synthetic fiber monofilament with a fineness of 1000 to 10000 deniers, metal fiber, or a material with high rigidity such as a vegetable fiber such as sisal, manila hemp, or balm, the number of ply twists relative to the number of ply twists is
The untwisting power of ply twisting is sufficient even when the number of ply twists is 1.0 to 1.5 times, but on the other hand, when using fine-grained fibers or fibers with high flexibility, the number of ply twists relative to the number of ply twists is
It is desirable to have a strong twist of about 1.5 to 3.0 times in order to exhibit untwisting power. If the number of first twists is less than 1.0 times the number of first twists, the untwisting force will be poor and the net 1 cannot be tightly twisted and focused, and if the number of first twists is 3.0 times or more compared to the number of first twists, especially once the net yarn 2 is created. In knotted knitting, the net yarn 2 easily develops kinks, making it difficult to handle, and also causes various troubles during knotted and knotless knitting, which is undesirable. In this way, the knotted net-like material 1A or the knotless net-like material 1B knitted to the required number of stitches and mesh mesh is subjected to the untwisting force of the mesh yarn 2 as the tension is released after knitting,
The knitted knotted net-like material 1A or knotless net-like material 1B is twisted in the untwisting direction and tightly bundled to form the rope-shaped product 3 of the present invention.

Using the product 3 of the present invention as a trunk net, seed threads from which young brown algae seedlings have been collected are wound around, tied or clamped at appropriate intervals, and stretched out into a long line to increase and cultivate brown algae. Of course,
The product 3 of the present invention is formed by converging a large number of net threads 2 in a spiral manner and forming a large number of convergence gaps 3A, so that it imparts appropriate turbulence to the tidal current and stimulates the zoospores of brown algae floating in the sea. Since the seedlings can be applied, the natural settlement of zoospores is significantly improved, and natural seedling collection and cultivation of the seedlings can be achieved simply by spreading the product 3 of the present invention.

The present invention has the above-mentioned configuration, in which the net-like material is knitted with knots or without knots with the number of stitches from 1st to 10th, and the number of final twists is 1.0 to 3.0 times the number of first twists. Due to the untwisting force of the net yarns that are strongly twisted in As the rhizoids grow, they become entangled and intertwined in a complicated manner within the focusing gap, and because the rhizoids straddle and wrap around a large number of net threads, the straddling wrapping area increases significantly and becomes strong. In addition, stable adhesion is achieved, and peeling and sliding due to tidal current resistance or wave resistance is significantly prevented, and production yield is greatly improved. In addition, in the present invention, since the mesh threads have knots or intersections at required intervals, even if they slip, uneven movement is prevented within the knots or intersections at each required interval, thereby preventing damage to the rhizoids. This prevents this and maintains homogeneous fixation and growth over the entire area, making it possible to achieve an even feeding effect for seafood on the shore.

In addition, since the present invention is knitted with a small number of meshes, it is possible to simultaneously produce several tens of meshes with one knitting machine, which not only makes it possible to provide a very low-cost product, but also to provide a knitted material with knots. When a net-like material is used, knots appear at required intervals, and when expanded, the knots exert a locking action when connecting with a float net or fixed net, improving long-term facility maintenance, etc. This is a mesh rope for algae cultivation that has the following characteristics.
