We estimate the economic value of changes in saltwater fishing regulations to anglers fishing on charter and private boat trips in southeastern U.S. waters. Our new estimates of angler willingness to pay (WTP) are for hypothetical changes in the bag limits for dolphinfish, Coryphaena hippurus; red snapper, Lutjanus campechanus; other/aggregate snappers, Lutjanidae spp.; grouper, Epinephelus spp. and Mycteroperca spp.; and king mackerel, Scomberomorus cavalla. We use a multispecies choice experiment with varying levels of regulations (e.g., bag limits), not catching or keeping fish. The focus on changes in regulations, instead of catch, allows us to explicitly consider how angler WTP might vary over the range of potential regulation levels, including closure. We compare three specifications of WTP for regulations that span the range of economically reasonable behavior: no decreasing marginal WTP (linear increasing WTP), piece-wise linear WTP, and absolute among trip attributes in the SPCE. In our approach, the choice situation faced by respondents in our survey more closely reflects the actual choice situation prior to a fishing trip, where regulations are known but fishing success is not. Our SPCE modeling also explicitly considers how angler values might vary over the range of potential bag limits, including zero which represents the case when the fishing season is closed. Much of the research on angler preferences assumes that the relationship between angler WTP and catching or keeping fish is linear or other simple function. A constant marginal WTP, i.e., a non-decreasing marginal WTP, is convenient for regulatory analysis, but, if incorrect, could lead to inaccurate estimates of changes in economic value. Furthermore, anglers’ value for regulations and catching or keeping fish might change in discrete ways that are crucial to consider in economic analyses. Anglers might place a large value on the opportunity to keep at least one fish, but value subsequently kept fish relatively less or not at all. We refer to the case where the angler does not value subsequently kept decreasing marginal WTP, where only the first unit has value (i.e., anglers care about the opening of the season but not about how many fish they may keep). We find absolute decreasing marginal WTP for four out of the five cases we can evaluate. We also test whether the WTP for regulations depends on the mode of fishing (charter or private boat). After controlling for differences in party size, we find no statistical evidence that the WTP differs between the two modes.
