Abstract.
The subject of research and implementation was large-sized pelagic trawls for catching dispersed shoals of fish in the open ocean.  In the new large-sized trawls, a new type of DYNEEMA fibers was used. The trawls tested were disigned  for 3,680 kW trawlers. At the first stage  of the research, tests were carried out on 1:10 scale models. Implementation tests were conducted on the Bering Sea on board the trawler M/T ACAMAR.
