Project Details
Description
The aim of the project is to reduce emission of climate gases in relation to the catch of brown shrimp by the Danish fishing fleet. This will be accomplished by a reduction of the fuel consumption during the fishing trip and by a diminished benthic impact that that will lessen the diffusion of substrate bound CO2 and methane. Gear changes/adaptations also aims at reducing the bycatch, potentially giving higher yield per trip in comparison to the traditional gear setup in the Danish brown shrimp fishery.
All the gear changes that will be tested are either known/developed by the participating fisher, in other fisheries or from other nations and will adapt to the conditions of the Danish brown shrimp vessels and the fishery. The tested changes include but is not restricted to; inserts of large mesh panels (>= 100mm), a lighter operated rolling beam, and a reduction in the numbers and a changed construction of the bobbins in the “ruller”. The larger brown shrimp fishing nations Netherlands and Germany have many different ongoing experiments and if they find positive results within this project period it will be valuable to test this under Danish conditions. In addition, a reduction in the bycatch of other species is expected without a loss of landing size shrimps.
The expected effects of the project are:
- Optimized design and use of a large-mesh panel that provides less bycatch, lower water resistance and thus lower fuel consumption and thus a greater quantity of landed shrimp per emitted kg CO2.
- Optimized fishing trip planning which, with the least fuel consumption, leads to areas with the highest catch of horse prawns.
- Test results of other gear modifications that the fishery has seen indications of is saving fuel.
- Reduced emission of climate gases from the bottom substrate – is largely unknown but the % reduction is proportional to the benthic stress.
Funding
The project is co-funded by the European Union through the Danish Maritime, Fisheries and Aquaculture Programme (EMFAF).
