Abstract

The invention provides a ship side board supporting rod type saury stick-held net. A piece of netting is connected to an upper border rope and a lower border rope, the two ends of the upper border rope are connected to one end, far away from the ship side board direction, of a first supporting rod and one end, far away from the ship side board direction, of a second supporting rod respectively, and the two ends of the lower border rope are connected to one end, far away from the ship side board direction, of the first supporting rod and one end, far away from the ship side board direction, of the second supporting rod respectively. The upper border rope is connected with one end of an upper lifting net rope, and the other end of the upper lifting net rope is connected to a net twisting machine. The lower border rope is connected with one end of a lower lifting net rope, and the other end of the lower lifting net rope is connected with a roller. According to the design, a supporting rod fixing device is applied to the saury stick-held net, the net is improved to be of an oval structure approximately, while the saury stick-held net is kept stable relative to the ship body, the sea sweeping area of the stick-held net is increased to the maximum, and the saury fishing yield is improved.

Description

technical field [0001] The invention belongs to the field of fishery devices, and in particular relates to a ship side stern pole type saury side lifting net. Background technique [0002] The stick-held net originated in Japan in the 1930s. Because of its simple operation, it was quickly promoted and applied. At present, the countries and regions engaged in saury fishery production in the high seas of the Northwest Pacific Ocean mainly include South Korea, Taiwan Province of my country and mainland China. Although larger fishing boats are used, the length of the upper line of the nets generally does not exceed 60m. At the same time, due to the fact that the saury clusters in the high seas and the resource density are relatively small compared to offshore waters, the existing nets in the original offshore side lift nets have different types of nets. The net gear designed on this basis, in the production process of saury in the high seas, the net coverage area in the water is ...
