云鳚单拖网技术研究

Design on the Single-drag-net For the Fishing of Enedrias nebulosus

为合理开发利用云鳚(Enedrias nebulosus)资源,设计了云鳚单拖网。2年的生产试验证明,云鳚单拖网生产效果良好,主机功率58.8—73.5 kW渔船在云鳚汛期(2个月)的捕捞产量达到250t以上,产值18万元以上,且比双拖网生产节油20％以上。专家鉴定认为,该项试验成果填补了国内云鳚资源开发利用的空白,居国内领先水平。

The single-drag-net was designed in order to exploit the fish resource reasonably.Practice indicated that the total yield of the fishing trawler whose main engine was 58.8~73.5 kW and equipped with the single-drag-net during the fishing season was above 250 tons,and the total value was above 180 thousand yuan,Furthermore,the oil consumption was decreased by 20 percent compared to the ship applying the double -drag-net.
