裤式拖网法是渔具选择性研究方法之一 ,其网形和校核试验于 2 0 0 2年 1月在挪威特鲁姆瑟海湾进行。在 1 1 5～ 2 70 m的水深范围内 ,测量的裤式拖网网口的水平扩张平均为 (2 3.2 7± 0 .2 6) m,网口高度为 (6.53± 0 .1 2 ) m;右网囊对左网囊的虾渔获物重量之比为 1 .0 0± 0 .0 4 ,右网囊对左网囊的渔获物尾数之比为 1 .0 8± 0 .0 9,渔获物种类及体长频率分布相似 ,基本符合用裤式拖网法进行选择性研究的要求 Pants trawling method is one of the fishing gear selective method, its net shape and verification test in January 2002 in Norway Trumpse Bay. In the water depth range of 115-170 m, the horizontal expansion of the pants trawl net averaged at (2 3.2 7 ± 0.26) m and the net port height was (6.53 ± 0.12) m ; The weight ratio of the left and right webs to the left webs was 1.08 ± 0.04 and the ratio of the right and left webs to the catch of the left webs was 1.08 ± 0. 0 9, catches species and body length similar to the frequency distribution, basically in line with the pants trawl method for selective research requirements
