Impacts of bait collection on Welsh Marine Protected Areas (MPAs): Crab Shelter
Survey to assess the impacts of three bait collection methods on Welsh MPAs - bait digging (Sites : Angle Bay, Four Mile Bridge, Penmon - Beaumaris), boulder turning (Penmon-Beaumaris, West of Great Orme) and crab shelters (Deganwy, Bangor Pier). Samples taken from control and impact sites. Infaunal cores, sediment cores, benthic megafauna (i.e. razor clam, cockle) quadrat, worm cast count, seagrass coverage, boulder epifauna, boulder turning classification.
This metadata covers the results of crab shelter monitoring at Bangor Pier and Deganwy.

Assessment of crab shelter provision as a bait collection technique was monitored at Bangor Pier, Gwynedd and Deganwy, Conwy where tyres and tiles have been observed being used to collect peeler crabs. Bangor Pier is adjacent to the Menai Strait and Conwy Bay SAC and Deganwy is located within the Aber Afon Conwy SSSI. Both sites are subject to crab shelter provision which has the potential to impact some of the designated features within each site.
Mudflats and sandflats and marine invertebrates were identified as target features for the survey, due to their demonstrated sensitivity to the impacts of crab shelter provision impacts, which can lead to significant changes in species
composition, reduced biodiversity, and altered habitat complexity.
Monitoring was carried out at Bangor Pier and Deganwy sites between 20-23 August 2024.
