<p>The present invention relates to a net for capturing ark shell larvae and, more particularly, to a net for capturing ark shell larvae that is manufactured by combining lengthwise fasciated yarn with widthwise linked yarn to make the holes of the net form quadrangles. It is not necessary to combine separate rope-shaped supporting strings at both side edges of a net when installing the net as reinforcing supporting parts, which is more compact than net hole parts, are formed at both side edges in a lengthwise direction of the net. Linked yarn with a constant width, which is colorless and odorless polyethylene yarn, is selected as the widthwise linked yarn, which is combined between the lengthwise fasciated yarn and the lengthwise fasciated yarn. The knitting stitch of a recovery part thereof is coupled to the knitting stitch of the lengthwise fasciated yarn and is fixed between the lengthwise fasciated yarn and the lengthwise fasciated yarn. The capturing rate of ark shell larvae is increased by additionally arranging reinforcing yarn and enabling the ark shell larvae to approach the net without aversion and to be captured by the linked yarn. Damage to the ark shell larvae is minimized in a separation step and separation efficiency is increased by facilitating the separation of the ark shells from the net when the ark shell larvae have grown up and the ark shells is forcibly separated from the net to send the ark shells to a farm. In addition, reduction in the width of the net during installation is minimized by reinforcing the tissue of the net and stabilizing the holes of the net to increase the durability of the net. The net for capturing ark shell larvae can be recycled as a net having a long lifetime is manufactured by preventing damage to the net when the net is drawn for withdrawal.</p> |
