Previous NMFS/MRFSS Recreational Valuation Research

• McConnell and Strand, 1994

• Hicks, Steinbeck, Gautam, Thunberg, 1999

• Haab, Whitehead, and Ted McConnell, 2000

Single Species Models

• Targeting behavior

• Species substitution

• Preference heterogeneity

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%) [self-reported and < 200 miles one-way distance], delete missing values on key variables (28% PRIM1 is missing)– n = 18,709 +/-

• Targets a species – n=11,257 +/-
