  1. Angler Heterogeneity and Species-Specific Demand for Recreational Fishing in the Southeast United States* Tim Haab (Ohio State University) Rob Hicks (College of William and Mary) Kurt Schnier (University of Rhode Island) John Whitehead (Appalachian State University) AFS Annual Meeting, Lake Placid, NY, Sept. 10-14, 2006 *MARFIN #NA06NMF4330055

  2. Our research will consider: • Targeting behavior • Compare various angler targeting models • single-species • aggregates of related species • all species combined

  3. Our research will consider: • Species substitution • Estimate angler willingness to substitute to other species or species groups when fishing quality or fishing management changes

  4. Our research will: • Estimate how willingness to substitute species might differ by angler type • socioeconomic factors • preferences • gear type (i.e., mode)

  5. Our research will: • Provide species-specific estimates of economic value for: • changes in fishing quality • management (e.g., size limits, bag limits)

  6. To date: • We have identified the feasibility of demand modeling at the species level • Estimated a prototype single species demand model

  7. MRFSS 2000 • LA to NC • n = 70,781 • Southeast 2000 (Limited Valuation Round) • n = 42,079 • Hook and line trips only (99%), day trips only (67%), delete missing values on key variables • n = 18,709 • Targets a species • n=11,257

  8. Fishing mode

  9. State of intercept

  10. Species • 425 unique species caught by recreational anglers sampled by the MRFSS • 15 species account for 82% of the targeting activity and 38% of the (type 1) catch

  11. Top 5 target species of interest

  12. Species groups

  13. Target Behavior

  14. Random Utility Models • Conditional Logit • U = X’β + e • Mixed Logit • U = X’δ + ε + e

  15. Dependent variables • Travel cost • [party/charter] TC = charter fee + driving costs + time costs • [private/rental] TC = driving costs + time costs • Predicted (type 1) catch rate • Depends on 5-year historic (type 1) catch rate • Big (20” or greater) • Small (less than 20”) • Historic big game catch rate • Number of MRFSS interview sites in the county

  16. Conditional/Mixed Logit Party/charter boatEight counties Private/rental boat Ten counties

  17. Conditional Logit Results Number of observations = 685 Number of alternatives = 18 Number of cases = 12330

  18. Mixed Logit Results Number of observations = 685 Number of alternatives = 18 Number of cases = 12330

  19. Economic value of one fish per trip

  20. Policy analysis • About 1.3 million dolphin trips in east coast of Florida • The welfare loss of new 20” size limit is about: • $15/fish/trip • x 1.3 million trips • = $19.5m (=/- 1 sd: $33.8m, $14.3m) • These costs could be compared to the benefits …

  21. Future work • Incorporate 1997 data • Consider species substitution models for: • Dolphin • King mackerel • Red drum • Spanish mackerel • Snapper-grouper • Aggregate species groups • Policy analysis: size limits, bag limits

  23. Nested Logit Party/charter Private/rental Ten counties Eight counties

  24. Nested Logit Results Number of observations = 685 Number of alternatives = 18 Number of cases = 12330
