Examining target species substitution in the face of changing recreational
The National Marine Fisheries Service (NMFS) is mandated by law to analyze
the benefits, costs, and economic impacts of the recreational fisheries
policies it promulgates. NMFS has developed single species models that
predict welfare and effort changes stemming from changes in various recreational
regulations. Little is known, however, about angler switching behavior
between species in the face of these same policy changes. That is, as
regulations are tightened for one species do those anglers quit fishing
entirely or switch to a substitute species with less stringent regulations?
Estimating these relationships requires specialized data collections involving
long-term panel studies to gauge revealed preferences or the presentation
of hypothetical scenarios to elicit stated preferences. NMFS is currently
pursuing the latter; conducting a stated preference mail survey that presents
anglers a series of choice scenarios that vary in quality, policy, and
species target attributes, and asks them to choose a preferred trip. Species
included in the scenarios include grouper, red snapper, king mackerel,
and dolphin fish. This data collection will field surveys monthly through
August 2004 using anglers sampled during the Marine Recreational Fisheries
Statistical Survey (MRFSS) creel survey and the MRFSS random digit dial
survey of coastal households in the South Atlantic and Gulf Coast states
of the US. This paper presents the preliminary results of the stated preference
survey, including a random utility model that examines the substitution
of target species under different policy scenarios.
