This is MARELITT Baltic

This brochure contains a simplified picture of the causes and consequences associated with derelict fishing gear in the Baltic Sea. It also presents the MARELITT Baltic project, aims and work process from an overall perspective.
The brochure is free to download.

Communication Strategy

All communication concerning the MARELITT Baltic project will be done in accordance with the Interreg guidance for communication and with the requirements of the Monitoring Committee (MC), the Managing Authority/Joint Secretariat (MA/JS). The aim of the communication in the MARELITT Baltic project is to ensure that external stakeholders are well informed about the progress, outputs and impacts of the MARELITT Baltic project.

Harbour Reception Survey  Report 4.1

The objective was to assess the readiness, capability and capacity of Baltic Sea fishing harbours to receive, separately collect and sort the derelict fishing gear (DFG) collected from the sea as well as end-of-life fishing gear. Fifty fishing harbours by the Baltic Sea were visited during the survey. The results reveal that more than half of the harbours selected for participation in the survey have organised waste management services at a reasonably good level...

Environmental Impact Assessment – Report (WSP Sweden)

The environmental impacts of DFG retrieval operations have, to our knowledge, never before been thoroughly investigated and development of guidelines or good environmental practices are needed. These guidelines can be used during the planning of retrieval operations to highlight the possible impacts the operation can have on the environment and can help to minimize these impacts. It is important to consider whether the retrieval operations themselves can cause harm to the marine environment, and therefore when it is accordingly better to avoid DFG retrieval.

Prestudy on Sonar Transponder – Report (Avalon Innovation)

One of the critical challenges of the MARELITT Baltic project is to identify more cost-efficient techniques – enabling more environmentally friendly, smoother and more accurate ways to detect and locate lost fishing gears. One potential way is to use hydro-acoustic surveying, like side-scan sonars. The MARELITT Baltic project has ordered a literature study on different kinds of technologies to strengthen the respond/echo from sonars to assess the possibility to “better see DFG in future”.

Recycling Options for Derelict Fishing Gear - Report 4.2

When derelict fishing gear (DFG) is retrieved from the sea, the material is highly mixed and contains metal anchors, chains, organic matter, and other marine litter as well as nets, ropes, float and sink lines. So how could retrieved fishing gear be treated to enter the value and recycling chain? And what preparation is necessary for a full recycle scheme? This report on technical feasibility describes in detail the results of all DFG recycling trials and the physical and chemical properties derived to evaluate the material quality of lost fishing gears retrieved from the Baltic Sea.


Ammunition Risk Assessment Study – Report (EGEOS GmbH)

This study concerns the safety of DFG retrieval crews and divers and the risk imposed by warfare ammunitions potentially encountered on seafloor or on wrecks.

In 2018 Baltic Diving Solutions were contracted by WWF Polska foundation on behalf of the MARLEITT Baltic INTERREG Project to perform diving operation of removal of abandoned fishing nets from the wrecks of the vessels in German and Polish sector of Baltic Sea.
