According to the netting structure and operation condition, the netting types of China's coastal bottom trawl are analysed in this paper. Several decades of typical trawl with a bag and wings used in offshore waters have been researched. A vast amount of statistics on netting design parameters have been made and analysed by the factors of netting structure and operation condition. It is finally considered that four netting types of bottom trawl are widely and effectively used in China. They are stern trawl, trawl with large mesh,trawl with large mesh improved and braided trawl. These trawls mentioned above meet the different requirements for their working conditions around all the offshore waters in China. To sum up, the four netting types of trawl have their own performances. The trawl with large mesh improved means high opening of mouth and mid-speed, stern trawl means both of medium,braided trawl means mid-opening of mouth and higher speed, and trawl with large mesh means low opening of mouth and higher speed.
