Description

  The present invention relates to a seaweed culture technique, and more particularly to a self-drying device for seaweed culture, a culture device, and a tidal self-drying method.

  As the aquaculture intensity increases due to the serious pollution of the nearby seas, nutrient deficiency is deficient, drought and rot of nori seaweed continues to increase, and the demand for construction of coasts and ports is also increasing, making it difficult to perform near-sea aquaculture. It is coming. From half-floating nori culture in the intertidal zone to rod-insertion type nori culture, the support rods that were 7-8m at the beginning of use become 16-17m, and the aquaculture area spreads to the deep sea and the open sea every year ing. However, support rods are limited in length and strength and cannot be used in deeper waters.

  Conventional full-floating raft nori culture methods include U-shaped full floating raft dry aquaculture method, triangle frame type full floating raft dry aquaculture method and turnover type fully floating raft dry aquaculture method However, these methods have many disadvantages as follows. First, since all of the aquaculture methods require artificial manipulation, labor intensity is high, maritime work is difficult, man-made control is also required for the drying time, and it is difficult to control immediately. May affect growth. Second, the resistance to wind is poor. Although the artificially operated drying device is fixed to the floating rope in the seaweed cultivation area, the whole seaweed farm is floating and is not fixedly connected to the seabed. The impact load on the root cable of the seaweed farm is so great that the resistance to wind is inferior. In addition, since the artificially-dried floating raft supports only the ends of the mesh crack when supporting the mesh crack, the force applied to the two points of the floating raft is unstable, and it tends to overturn and tilt when subjected to wind shocks. In addition, it is not suitable for use in a sea area where the wind is large, and the wind prevention performance of the device itself is not good. Third, it is not completely dried. When drying by an artificial operation, since the wind makes the device unstable, the center of the device must be lowered, so it is difficult to completely dry the seaweed in the sea wave action. Fourthly, the work efficiency is low because the laver collection cannot be mechanized. The artificially-dried all-floating nori culture method requires artificial collection because the nori collection vessel cannot enter the bottom of the net cracks and harvest the nori and is blocked by the raft frame. Therefore, since a lot of labor is required, work efficiency is low. In addition, since it is difficult to control the length of the netted seaweed after harvesting, young laver and grown seaweed may be mixed in the next collection to affect the quality of the seaweed. Fifth, artificially dried net cracks must be removed from the water at once, but because the weight is heavy, the number of floating rafts increases and the operation time becomes longer, so the production volume is high for the high seaweed culture cost Few.
