摘　　要：本文报道了改进设计的专用鳀鱼变水层拖网1994～1995年期间海上的试验结果。试验结果表明:该网的结构合理,网具性能优良。网口高度达12.6m,拖速提高到3.0～3.8节。拖网阻力比原生产网减少19％,平均网次产量比原生产网增产35.3％。This article reports the testing results of the improved pelagic trawl of pair - boat, which designed specially for the catching of anchovy. The experimental results showed that the net structure was reasonable and the trawl performance was fine. The height of the net opening is 12.6 meters. Trawling speed is increased io 3.0 - 3. 8 knots. Compared with former productive net, the trawling resistance of the net is reduced by 19% , and the average catch per haul is increased by 35.3%.
