Description

Vertical multi-tiered seaweed cultivation rack The present invention relates to a cultivation stand for cultivating seaweed by mounting vertically arranged nets in multiple stages, and more specifically, to a vertically multi-stage cultivation stand for cultivating seaweed in which multiple stages of nets are mounted vertically on a support connected via a wire to a lifting shaft that rotates forward and reverse by a control motor, and the nets are immersed in and removed from a seawater tank that stores seawater at regular intervals. Gim, also known as haetae, grows attached to underwater reefs like moss. It measures 14–25 cm in length and 5–12 cm in width. Its body is elongated oval or linear egg-shaped with wrinkles along the edges. The upper part of the body is reddish-brown, while the lower part is bluish-green. It consists of a single layer of cells, which are irregularly triangular, quadrilateral, or polygonal and arranged irregularly. The cross-section is quadrilateral, with the height being greater than or nearly equal to the width. The cells at the base are egg-shaped or oval and produce large, colorless rhizoids. In the East, artificial cultivation has been practiced since early times because natural reproduction alone could not meet the demand for laver. For artificial laver cultivation, materials for attaching the spores are installed in the sea in the autumn when the spores emerge, and the laver is collected and cultivated. Although laver attaches well to anything, such as rocks and branches, bamboo mats woven from bamboo strips and nets made of synthetic fibers are commonly used. Suitable locations for laver farming are calm inland bays with good tidal circulation and some influence from river water, ideally having a specific gravity of 1018 to 1028. It is unsuitable if the specific gravity drops below 1017 due to excessive freshwater inflow during floods. Since water temperature and light intensity are crucial for laver growth, special attention must be paid to the installation depth of the farming nets, taking into account tidal fluctuations. In Korea, farming is practiced along the coast of Jeollanam-do and Gyeongsangnam-do, with laver farming in Wando, Jeollanam-do, being particularly famous. Seaweed farming can be divided into stake farming and floating farming; stake farming is suitable for the West Sea, where the tidal range is large, while floating farming is suitable for the South or East Seas. First, stake-type seaweed farming is a method of cultivating seaweed by installing stakes vertically in tidal flats where seawater flows in and out with the tides, and installing seaweed farming nets with seaweed spores planted on the stakes. In pole-type seaweed farming, the nets are submerged in seawater during high tide and exposed during low tide, allowing them to receive wind and sunlight. This prevents the growth of seaweed diseases and algae, and prevents the occurrence of viruses. However, it has the disadvantage of high installation costs. Recently, with the expansion of land reclamation projects, pole-type seaweed farming, which was previously used in coastal areas of the West Sea, has disappeared, and floating-type seaweed farming is being implemented in the open sea off the coast. Gim is a organism that grows in the upper layer of the intertidal zone, which is submerged during high tide and exposed during low tide. As an intertidal organism (submerged 15 cm), gim needs to be exposed to water for about 4 hours, roughly twice a day, to grow well. Therefore, this is the reason why stake-type gim farming is active in parts of the West Sea and South Sea, where there is a difference between high and low tides. As seaweed farming technology advances, the area where seaweed is cultivated is expanding from the South Sea to the East Sea. Since seaweed farming in the South Sea and East Sea is a floating method, the success of seaweed farming in the South Sea or East Sea depends on how well the process of floating and exposing the seaweed to water twice a day is carried out. The reason is that if the seaweed farming nets are not properly exposed to sunlight, naturally, harmful algae and pathogens growing in the submerged area will invade the submerged seaweed farming nets, and damage such as the death of the seaweed will inevitably occur. Therefore, floating seaweed farmers must go out to sea every day and flip over the seaweed nets, which have floats made of styrofoam balls facing upward, so that the seaweed is exposed to sunlight. However, the time required to flip over these seaweed nets is too long, so not only can work efficiency not be improved, but there is also the disadvantage that a large amount of manpower is required to flip the nets. In addition, although floating seaweed farming has the advantages of reduced installation costs compared to stake-type seaweed farming and a low attachment rate of unwanted algae due to the smooth circulation of water currents, resulting in superior s
