Abstract:
The aims of the project are to develop a GIS-based method or tool to assist in the strategic development of fisheries, and to apply the methodology in a pilot study area a South East Wales. The tool is intended to enable spatial analysis of angling opportunity and participation across an Area or Region. This will help fisheries managers in deciding on locations where development of fisheries will result in the greatest social and economic benefits, thereby prioritising investment in fisheries. The tool can be applied on two levels, a basic map-based level and a more advance spatial and statistical level. The map-based level involves visually assessing the distribution of anglers and fisheries across an Area or Region, which can provide a kind of agap analysisa of fishing opportunity. The spatial-statistical level involves more in-depth spatial analysis and quantifying the effect of angling opportunity on participation. The results of such spatial-statistical models can then be used to compare between sites on the basis of numbers of population zones affected and/or numbers of new licence holders generated. The results of the spatial-statistical models using South East Wales data, show that angling opportunity does indeed have a significant affect on participation. A 1km decrease in straight-line distance to fisheries increases licence holders by between 3 and 10%. Similarly a 10% decrease in travel time to fisheries increases licence holders by between 3 and 10%. And an additional fishery within 10km of postcode sector centroids increases licences by 1%. The report applies these results to three case study examples of fisheries development sites in South East Wales, to illustrate how the spatial-statistical component of the tool could be used in fisheries management decisions. Recommendations to take the work forward include to: a Produce maps of angling opportunities by type for other Agency Areas; a Develop the measure of angler opportunity e.g. obtain data on size of fishery; a Develop the measure of angling participation, e.g. estimate more accurate levels of use using the ratio of licence holders to days fished. a Link spatially referenced databases of fisheries with databases of river characteristics. i Science Report Defining Angler Opportunity: Phase 2 Report CONTENTS 1 Introduction 1.1 Introduction 1.2 Structure of report 2 Developing the data and methodology 2.1 2.2 2.3 2.4 3 Measures of angling participation Population data Measures of angling opportunity Fisheries density Extending the analysis 3.1 Spatial analysis of licence holders and fisheries 3.2 Correlation 3.3 Modelling 4 Discussion of the spatial model results 4.1 Applying the results 4.2 Case study conclusions 1 1 1 3 3 3 3 6 7 7 12 13 18 19 25 5 Conclusions 26 6 Recommendations 27 List of Figures List of Tables Annex A iii iv 28 Science Report Defining Angler Opportunity: Phase 2 Report ii LIST OF FIGURES Figure 1.
