Summary

A pilot study has been conducted to determine whether the theoretical combination of habitat sensitivity to fishing activity of different gear types. This theory was converted into a model, and run using combined fishing activity data, collected through the FishMap Mon pilot project, to predict the sensitivity of habitats. The objective of this data capture was to determine whether the data on resistance to fishing activity data for each fisheries habitat developed during the NRW habitat sensitivity project could be applied to the impact of cumulative fishing activity on each habitat. Specific aims of the modelling project were to: - Calculate footprint versus resistance curves for each fisheries habitat and fishing activity using the revised activity footprints calculated for the FishMap Mon project - Develop a methodology to model combined fishing effects - Test the methodology on Red Wharf Bay and Conwy Bay - Produce an output layer at 1 km grid resolution - Produce thematic maps The source GIS data was collated during the FishMap Mon project using a standard questionnaire and post-processing method. The resistance and intensity definitions were supplied by the FishMap Mon project team. The curves were calculated using an automated process to ensure processing was identical for all habitats and visually verified to ensure a good fit. This project was a pilot to determine feasibility of the use of such models, therefore the output data is suggestive of the habitat sensitivity.

• Access contraints: The following data is considered OS derived data and is therefore jointly owned by NRW and the Ordnance Survey. This dataset is sensitive and restricted. The sensitive data is the precise locations of fishing activities, and the data also contains specific information about the fishing activities, and so is restricted to the FishMapMon Team and certain partners - contact the dataset owner for more information. Sensitive data must be kept confidential; general release is not permitted due to risk of harm to the environment or third parties. Sensitive data may only be released under an appropriate NRW Licence. Requests should be referred to NRW's Access to Information Officer. Data may be released freely if the sensitive records are removed in advance, or shown only at a coarser scale.
