Europe, inland waters
In the Wadden Sea and in the Oosterschelde, common cockles are harvested by hand, by means of a [hand dredge]. This is a kind of rake with a net attached to it, that is pulled through the upper layer of the seabed by hand. The fishermen work at low tide on sandflats. The yearly yield of this method is 300 to 600 tons of cockle meat. The yearly maximum that may be caught in the Wadden Sea is 2.5% of the harvestable stock. In the Oosterschelde there is an ecological food reservation limit of 5000 tons. This may not be fished but is food for birds and fish. In 2012 the Dutch hand caught cockle fishery became MSC-certifiedMSC Certified:
Fisheries that comply with the Marine Stewardship Council assessment criteria and are certified. Fish products with the blue MSC label are caught by sustainable fisheries..
