  2. PRESENTATION • Model components • Methodology • GIS model of the Grand Banks • Impacts analysis • Issues CORS National Meeting 2007

  3. MODEL COMPONENTS • Space – Grand Banks mapping • Planning period – 1977-2005; 2006-2010 • Grand Banks fish stocks (10) • Fleets: (5) Harvesting and Processing • Communities: Newfoundland (10) and Nova Scotia (5) CORS National Meeting 2007

  4. METHODOLOGY SpatialTemporal Stock Assessments Module 1 Stock Status Data Stocks Fishing Mortality Fleets Attribution Annual Catch Schedule per Stock Module 2 ZIFF Files Fleet Harvesting Costs & Revenues Module 3 Fleets Characterization Fleet Integrated Economic Performance Harvesting and Processing Employment & Labour Earnings Community Population Module 4 CORS National Meeting 2007

  5. GIS MODEL • Mapping using ArcGIS and Google Earth • Species presence, catch, effort and value • GIS analysis • Spatial-temporal animations CORS National Meeting 2007

  6. IMPACTS ANALYSIS • Species and Gears • Economic impacts – historical and projections • Report conclusions and issues CORS National Meeting 2007

  11. Economic Inputs - Historical CORS National Meeting 2007

  12. Historical Economic Impacts and Projection Scenarios 2006-2010 • Status Quo – extension of recent history (post 1995) • Negative – “worst case”, decline in stock-recruitment, depressed prices, homogeneous gear allocations • Positive– “best case”, improved stock-recruitment, improvements in prices, homogeneous gear allocations CORS National Meeting 2007

  13. Economic Impacts – SQ Harvesting CORS National Meeting 2007

  14. Economic Impacts – SQ Processing CORS National Meeting 2007

  15. Economic Impacts - Negative CORS National Meeting 2007

  16. Economic Impacts - Positive CORS National Meeting 2007

  17. Communities Impacts CORS National Meeting 2007

  18. Ecosystem Impacts of Trawling • Studies of small relative areas • Kenchington et al (2006) – Maritimes review • Gilkinson et al (2006) – NL review • Rice (2006) – International review • Results depend on extent of trawling • Larger impacts on heavily trawled ecosystem communities CORS National Meeting 2007

  19. ISSUES • Policy/Management need for understanding spatial-temporal impacts • Data requirements and availability • Can’t extend small-scale analysis • Exercise in system validation through data analysis CORS National Meeting 2007

  20. ISSUES • Model good for testing “what-if?” hypotheses for ecosystem interactions • Benefits for integrated strategic planning • Policy evaluation tool CORS National Meeting 2007
