Description

In the Limfjorden, cockles are only caught as a by-catch of the blue mussel dredge fishery, mostly associated with cockle surfacing behavior where buried cockles move to the surface of the sediment.

In the last five years (2013-2017) cockle landings in the Limfjorden reached the same value as blue mussel landings and now represent ca. 35% of European Union cockle catches by weight. Therefore, industry and governmental agencies are interested in the regulation and management of the cockle fishery and population in the Limfjorden. The COCKLE projects implements the first research plan on the cockle population of the western Limfjorden.

Project aims:
- Evaluate the historical cockle fishery in the Limfjorden as a by-catch of the blue mussel fishery
- Evaluate the cockle population abundance and structure in the western Limfjorden
- Assess the impact of the cockle fishery on cockle populations
- Evaluate cockle surfacing behaviour and its links to environmental, biological and fishing activities
- To perform an initial census of pathogens and parasites in the Limfjorden cockle population

The project is divided into a number of interrelated work packages:
WP 1: Historical data
WP 2: Spatial survey and baseline assessment of cockle populations in the Limfjorden
WP 3: Surfacing survey and fishing events
WP 4: Monitoring and experimental evaluation of cockle population surfacing
WP 5: Pathogens and diseases in C. edule in the Limfjorden: baseline and management perspectives
WP 6: Management and dissemination.

The projects is coordinated by DTU Aqua and is funded by the European Maritime and Fisheries Fund and the Danish Fisheries Agency.
