Turbulent flow interacting with flexible trawl net structure including simulation catch in flume tank [PDF]
Scientific Reports, 2023 The interaction between fluid and the midwater trawl with stocked catches is extremely complex, but essential to improve the understanding of the drag force acting on the trawl, the behavior of the fishing structure during a trawling process, and to ...

Journal of Marine Science and Engineering, 2021 The codend of a trawl net is the rearmost and crucial part of the net for selective fish catch and juvenile escape. To ensure efficient and sustainable midwater trawl fisheries, it is essential to better understand the drag characteristics and fluttering

Journal of Marine Science and Engineering, 2023 The authors have developed a method to estimate the catch efficiency of sampling gear using acoustic information. Since different sampling conditions will cause different sampling results, it is necessary to know more details about catch efficiency to ...

Engineering calculation of a midwater fishing trawl
Vestnik Tomskogo gosudarstvennogo universiteta. Matematika i mekhanika, 2023 This paper presents a method for calculating the power and geometric properties of a midwater fishing trawl, which is a complicated engineering structure made up of tied flexible (threads, ropes, flap) and rigid (rigging, trawl boards) elements. A computational model, the functional relations for internal forces and geometric characteristics of the ...
