Influence of Material with Medium and High Molecular Weight Replacing Polyethylene on Trawl Performance
East China Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, Shanghai 200090, China
Taking single-boat trawling fishing in West Africa as the research object and maintaining the breaking strength of the original netting gear as the standard, we used medium- and high-molecular-weight materials to replace common polyethylene material in producing the trawl model. Test results showed that, under the same test conditions, the resistance of medium- and high-molecular-weight material trawls decreased by 16.80% compared with that of most of the common polyethylene material trawls. The maximum difference in the height of the net opening between the two material trawls was approximately 2.3 m. The energy consumption coefficient decreased by 23.65%.
