Our research will consider:

  • Targeting behavior

    • Compare various angler targeting models

      • single-species

      • aggregates of related species

      • all species combined


Our research will consider l.jpg

Our research will consider:

  • Species substitution

    • Estimate angler willingness to substitute to other species or species groups when fishing quality or fishing management changes


Our research will l.jpg

Our research will:

  • Estimate how willingness to substitute species might differ by angler type

    • socioeconomic factors

    • preferences

    • gear type (i.e., mode)


Our research will5 l.jpg

Our research will:

  • Provide species-specific estimates of economic value for:

    • changes in fishing quality

    • management (e.g., size limits, bag limits)


To date l.jpg

To date:

  • We have identified the feasibility of demand modeling at the species level

  • Estimated a prototype single species demand model


Mrfss 2000 l.jpg

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

Species l.jpg

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

Random utility models l.jpg

Random Utility Models

  • Conditional Logit

    • U = X’β + e

  • Mixed Logit

    • U = X’δ + ε + e


Dependent variables l.jpg

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

Economic value of one fish per trip l.jpg

Economic value of one fish per trip


Policy analysis l.jpg

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 …


Future work l.jpg

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
