  Citation × Citation Citation Abstract Copy Title: From Shark Fin Markets to Shark Populations: An Integrated Market Preference Cohort Analysis Of the Blacktip Shark (Carcharhinus limbatus) Author: Fong, Quentin S.W., Anderson, James L. Year: 2001 The increasing demand for shark fins in Asia and the shark s life history pattern of slow growth, late maturity, and few offspring, have generated concerns regarding the sustainability of shark resources. Despite this concern, little effort has been spent on understanding the markets for shark fin products and the population dynamics of sharks. This work incorporates the results of a conjoint analysis of dried processed shark fins from Hong Kong into a cohort model of the balcktip shark with the objective of maximizing the utility of Hong Kong shark fin importers/processors. Results show that optimal harvest sizes and ages for all mortality and discount factor scenarios are greater than the maturation sizes and ages for both male and female blacktip. Policy implications for this study are also discussed.
