• 32. [Article] Location for Random Utility Models From Uncertainty in Self-Reported Spatial Data: Determining the Value of Coral Reefs

  Citation × Citation Citation Abstract Copy Title: Location for Random Utility Models From Uncertainty in Self-Reported Spatial Data: Determining the Value of Coral Reefs Author: Jarvis, Sonia Greater awareness of the importance of ecosystem services and ecosystem management has sparked interest in examining on-the-water location choices of fishermen; however, some studies still rely on selfreporting due to high costs or governmental restrictions to obtaining GPS and satellite information. Selfreported data may be inaccurate due to spatial comprehension difficulties or an unwillingness to truthfully report on-the-water locations. Uncertainty in spatial data can lead to significant differences in the outcomes of valuation studies since travel cost estimates are highly dependent upon location specifications. This study examines the implications of uncertainty in self-reported data on willingness to pay estimates obtained from random utility models using self-reported data from recreational anglers in Puerto Rico. Inability to translate on-the-water locations to grid cells on a map and concerns about area closures may have adversely impacted the quality of data obtained from these fishermen. This study examines the effects of locational uncertainty on the estimated value of coral reefs around Puerto Rico.

• 34. [Article] The Limits of Risks Hedging in Aquaculture: The Case of Shellfish Farming in France

  Citation × Citation Citation Abstract Copy Title: The Limits of Risks Hedging in Aquaculture: The Case of Shellfish Farming in France Author: Le Bihan, Veronique, Pardo, Sophie Shellfish farmers make their production decisions in an environment characterized by multiple uncertainty. As shellfish farming is done in an open area, producers face a large number of risks: e.g. biological, environmental, pollution or climatic risks. Historically, this sector has been affected by several crisis; the last ones were the unexpected mortality of spat in 2008 and 2009. Insurance is one important potential mechanism for managing this kind of risks (e.g. crop insurance in agriculture), but shellfish farming had limited insurance availability in France. The purpose of this article is first to determine specific risks of this segment of agriculture. We then present the existing hedging mechanisms, from self-protection / self-insurance measures to the possible intervention of the Fishery European Funds. We analyze the limits of such instruments and we try to explain why efficient protection is not available for this sector. Main reasons of such a lack are: High level of ambiguity in risks definition, individual correlation and the high degree of specialization of a small sector, what limits the possibility of risk pooling.

  Citation × Citation Citation Abstract Copy Title: Application of a Dynamic Stochastic Adaptive Bioeconomic Model to Evaluate the Economics of Offshore Bluefin Tuna Aquaculture Author: Shamshak, Gina Louise, Anderson, James L. Over the past fifteen years, the market for bluefin tuna has evolved in an attempt to further enhance the economic value of bluefin tuna landings. Historically, the US East Coast has been a major supplier of high quality bluefin tuna to Japan, the primary market for sashimi grade tuna. To date, many questions regarding the economic feasibility of offshore aquaculture, and in particular offshore bluefin tuna farming in the United States, remain unanswered. This research assesses the economic feasibility of an offshore bluefin tuna aquaculture industry located on the East Coast of the US by developing a dynamic stochastic adaptive bioeconomic model of such an offshore enterprise. The bioeconomic model incorporates the biological constraints of the species, the interaction of relevant economic parameters and constraints, and stochastic sources of risk, to solve for the profit maximizing behavior of a farmed bluefin tuna producer. This research identifies the optimal harvest schedule for an offshore bluefin tuna farming facility that maximizes the net present value of the operation under a variety of economic, biological and regulatory conditions. Economic feasibility is analyzed using profitability indicators including net present value (NPV) and internal rate of return (IRR). This research is relevant given the continued expansion of bluefin tuna aquaculture globally, the increasing demand for high-quality bluefin tuna, and the uncertainty regarding the economic feasibility of an offshore bluefin tuna aquaculture industry in the United States.
