Abstract

© 2019 Elsevier LtdData on fishers' spatial distribution are vital, driven by a requirement for evidence-based management, and the trend towards Marine Spatial Planning. Intertidal fisheries have received considerably less attention from managers and scientists, compared to inshore and offshore counterparts to date. The need for additional intertidal fisheries data to inform management, specifically within European Marine Sites, has been identified. The purpose of this study is to map the spatial distribution of the data-poor Northumberland lugworm fishery, relating this to the sensitive features, habitats, and species present within the Berwickshire and North Northumberland Coast European Marine Site (BNNC EMS), ultimately mapping the vulnerability of areas to lugworm bait digging. Suitability, sensitivity, and vulnerability to the lugworm fishery were spatially modelled using cost-effective methodologies. Weighted Linear Combination models were created using both collated (e.g. sediment type, conservation designations) and collected data (e.g. lugworm density and size). Data processing was undertaken in GIS, and criteria weightings were assigned from expert interviews. Model outputs revealed the most intensely harvested sites (most suitable), the areas which contained the most sensitive habitats or species (most sensitive), and the sites which were most likely to be impacted by the lugworm fishery (most vulnerable). Extant spatial management measures within the BNNC EMS (e.g. byelaws) were found to encompass the majority of the most vulnerable areas identified, with exceptions highlighted for marine managers. There is scope for methods to be developed further, for additional intertidal fisheries and localities, as a useful management tool where spatial data are lacking.
