Collection Activity and Crab Survey in the Menai Strait (2009) dataset https://portal.medin.org.uk/portal/start.php?tpc=007_NRW_DS115077 Special Areas of Conservation (SACs) are strictly protected sites designated under the EC Habitats Directive. In the Menai Strait and Conwy Bay SAC the relevant Annex I intertidal habitat features are Mudflats and sandflats not covered by seawater at low tide and Reefs. Specific areas of interest include areas of tide-swept bedrock and boulders and areas of tide-swept Fucus serratus on mixed sediment along the Menai Strait. In previous studies it was noted that a portion of the boulders had been turned by bait collectors. Surveys to assess bait collection activity and crab counts were carried out along the length of the shoreline of the Menai Strait using student volunteers. Data quality and confidence considered high. 20101130
