Commercial Fishery Department tests new fishing systems

In the hydrochannel of Fischering Service LLC, students and postgraduates of the Commercial Fishery Department under the guidance of their lecturers and the Head of the Commercial Fishery Department, Candidate of Engineering Sciences, Associate Professor A.A. Nedostup, conducted experimental studies with a catamaran model and a pelagic trawl.

During the experiments, the researchers worked out the interaction between the aggregate trawl resistance and the vessel's available thrust for the first time.

It is very difficult and expensive to carry out such tests in full-scale conditions.

Therefore, a group of scientists developed 3-D computer-aided design software to determine these parameters as part of the preparations for the trials.

While previous experiments have made the trawl's aggregate resistance well known, further research is required to determine the vessel's parameters, in particular the characteristics of its available thrust.

During hydrochannel work, the researchers created near-field conditions and determined the correct vessel-trawl coupling, saving energy on the installed electric motors and significantly reducing the carbon footprint.

These studies are suitable for the development of not only the Autotrawl system, which allows unmanned fishing, but also for remote-controlled fishing as a drone-vessel-trawl system.

According to the researchers, these systems can be several, for example, a parent ship with a number of such drones that independently conduct fishing.

The research is carried out within the framework of the state task 3/2025 Development of a Wireless Monitoring System for Trawl Parameters with Elements of Artificial Intelligence Autotrawl.

KSTU Department of Commercial Fishery would like to express gratitude to A.N. Fedorov, Director of Fischering Service LLC, for the opportunity to conduct experimental research in the hydrochannel.
