| Abstract: | 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%. |

| Keywords: | Pelagic trawl of pari - boat height of net opening vertical opening coefficient |
