The Upper Paraná River floodplain is the last lotic stretch of an ecosystem seriously threatened given that circa 50% of the original ecosystem has been converted into reservoirs. To assess the recreational value of the Upper Paraná River floodplain, 174 tourists were interviewed using the Willingness to Pay--WTP and Travel Cost--TC methods. The annual aggregated WTP attributed by tourists was ...

In this study we assess the ability of the Marine Recreational Fishery Statistics Survey (MRFSS) to support single-species recreation demand models. We use the 2000 MRFSS southeast intercept data combined with the economic add-on. We determine that the MRFSS data will support only a few species-specific recreation demand models. Considering species of management interest in the southeast, we fo...

Assessing the motivations and wildlife-related value orientations (WVOs) of outdoor recreations, such as recreational fishing (RF), is key importance to understand human dimensions natural resource use inform management actions. Using a national random telephone survey, we contrasted participation rate, socio-economical profile, WVO participants RF, recreation (OR), consumptive (COR), indoor (I...

The aim of this study was to assess the potential risk of infection constituted by HAV to persons using surface dam and river water for domestic and recreational purposes. It estimates the potential risk using a deterministic exponential risk assessment model with mean values and conservative assumptions. Hepatitis A virus was detected in 17.5% of river and 14.9% of dam water samples tested. Th...

Many communities are interested in developing and maintaining recreational trails to benefit trail users and as tourist attractions to stimulate economic growth. In this paper, a study is described which estimates the net economic value to trail users and the local economic impacts of the Virginia Creeper Rail Trail in south-western Virginia, USA. The monetary valuation results suggest that the...

Executive Summary Introduction Recreational fishing represents a popular and highly valued use of marine resources, with participation by a large percentage of the U.S. population. Nonetheless, many recreational fisheries, including a number of fisheries in the Gulf of Mexico (GOM) recreational reef fish complex, show trends towards shorter seasons, smaller bag limits and more restrictive size ...

The increasingly intense competition between commercial and recreational fishermen for access to fish stocks has focused attention on the economic implications of fishery allocations. Indeed, one can scarcely find a management plan or amendment that does not at least refer to the relative food and sport values of fish and to how expenditures by commercial and recreational fishermen on equipment...

Daily harvest limits are a common form of regulation in consumptive recreation. We show that angler willingness to pay for bag limit change is an option price and how it relates the value changes. Specifically, if expected utility theory holds, then prices one-fish increments along with catch distributions can be used “recover” compensating surplus (CS) increments. also further assumptions (e.g...
