Improving the technique of fishing for Pacific squid

Abstract

The paper considers the problems arising in the trawl fishery for Pacific squid and suggests ways to solve them. The necessity of using flexible spacers (GRU) for horizontal opening of trawls when working on difficult soils and for stable output of the trawl system to the surface is shown. The ease of control of the trawl system with the GRU is shown in contrast to the trawl systems with boards. To ensure a large horizontal opening of the trawl and reduce drag, it was proposed to use multi-wall trawls. According to calculations, the proposed trawl sys-tems will reduce fuel costs by 1.7-2 times and, accordingly, will reduce the carbon component (CO₂ emissions).
