Abstract:Fishing effect of the pelagicl trawl with big meshes depends on aimed fishing grade. The approach of controlling and determining the operation water layer of pelagical trawl with big meshes made by the adjustment of buoysinker force, warp length, towing speed and distance between ships is put forward according to the writer's experiments and researches for many years. It is widely applied in production practice and has achieved good results.
Keywords:pelagical   trawl with big meshes   aimed fishing   buoy - sinker force   net position
