9 Factors influencing the rope tension of saury stick-held lift nets SHI Yongchuang 1, ZHU Qingcheng 1, 2, 3, ZHANG Yandong 1, HUA Chuanxiang 1, 2, 3, ZHOU Wenbo 1 1. College of Marine Sciences, Shanghai Ocean University, Shanghai , China; 2. National Engineering Research Center for Pelagic Fishery, Shanghai Ocean University, Shanghai , China; 3. Key Laboratory of Sustainable Exploitation of Oceanic Fisheries Resources, Ministry of Education; Shanghai Ocean University, Shanghai , China Abstract: We evaluated the influence of haul speed and leadline weight on net tension in Cololabis saira stick-held lift nets. Tests were carried out in a water tank using a scale model net in November December, The tension on the siderope and leadline of the model net increased with haul time. The tension approached a maximum near the end of the haul. The tension on the model net siderope and leadline increased as the hauling speed increased and the rate of increase in net speed accelerated as the hauling speed increased. The hauling speed at m/s had a significant effect on rope tension (P<0.05), while at hauling speed of m/s, the change in rope tension was stable. The tension in the model net sideline and the leadline increased when the leadline weight increased, though there was no effect on rope tension. Our observations provide insight into ways to improve rope tension performance and a reference for fishing operations. Key words: Cololabis saira; stick-held net; rope tension; model test; hauling speed; leadline weight Corresponding author: ZHU Qingcheng. qczhu@shou.edu.cn
