Description

Intertidal cockle surveys are conducted annually in spring between the end of March and throughout April. Data is collected for stock assessments to inform fisheries management of the Wash Fishery Order 1992 regulated cockle fishery (Total Allowable Catch, which beds to open, spatial closures to protect juvenile stocks and to identify potential issues that might cause natural mortality to occur as a result of over-crowding). Data also forms part of the Habitats Regulation Assessment (HRA) process required to open a fishery under Regulation 61 of The Conservation of Habitats and Species Regulations 2010 (SI No. 2010/490), regarding The Wash and North Norfolk Coast Special Area of Conservation (Habitats Directive), The Wash Special Protected Area (Birds directive), the Wash Ramsar and SSSIs. Surveys are conducted on the intertidal sandbanks and mudflats of The Wash, which are broken down into 22 beds/survey areas. The survey incorporates approximately 1,250 sample stations that are arranged in a regular grid pattern with the same stations being used each year. Sampling is conducted either using a 0.1m2 Day grab over high water periods or by sampling on foot at low water using a 0.1m2 quadrat.
