Improving the selectivity for cod in Danish trawl fisheries (38887)

Project Details

Description

The aim of the project was to develop and test more selective fishing gear for three major Danish fisheries:
- The demersal trawl fishery in the North Sea (120 mm)
- The demersal trawl fishery in Kattegat and Skagerrak (90 mm)
- Improve the selection range (SR) in the BACOMA codend used in the Baltic Sea.

The new and more selective fishing gears were developed under consideration of the economy in the fishery. The project delivered three new selective gear solutions of which two were tested during experimental fishery. Technical descriptions of the new designs were delivered. Furthermore, an economical model to quantify the economic consequences of using the new selective fishing gears compared to existing standards was developed.
Experiments were conducted in the Baltic Sea cod fishery demonstrating that the selection range (SR) could be reduced by using a larger diamond mesh in the lower sheet of the BACOMA design. Further the project demonstrated the efficiency of legal selective escape panels in Skagerrak/Kattegat and the effect of varying design parameters in both the panel section and the trawl body. Finally the project demonstrated that active stimulating fish behavior around selective escape panels significantly can improved the escape panels’ selectivity.

The project was coordinated by DTU Aqua and funded by the Danish Ministry of Food, Agriculture, and Fisheries and the European Fisheries Fund (EFF).
