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

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 ...

FEATURES OF FISH BEHAVIOR IN THE ACTION ZONE OF MIDWATER TRAWL
Vestnik of Astrakhan State Technical University. Series: Fishing industry, 2017 Researches in the field of behavior and distribution of fish at different stages of fishing were conducted using midwater trawls in order to increase fishing efficiency, subject to the fact that, besides fish behavior, parameters of midwater trawls and types of trawling affect the efficiency of trawling.

Modeling of the Midwater Trawl Dynamical Behavior Based on R Language [PDF]
Proceedings of the 2015 International Conference on Mechatronics, Electronic, Industrial and Control Engineering, 2015 The midwater trawl is used widely in many oceanic fisheries. In this study, the midwater trawl dynamical behavior was simulated and modeled with the mathematical mechanic equations based on R language platform. A lump-mass and spring method was used to build the physical model.
