| Individual transferable quotas (ITQs) have become a popular management tool for fisheries. They have been promoted in some quarters and seriously criticized in others because of their social and economic impacts. A more serious problem is that ITQs provide exclusive access to public resources presumably in return for some public benefit, namely conservation; however, in a high percentage of cases they do not conserve fish stocks. In this article, we focus on the reasons that ITQs do not conserve stocks. We point to a number of phenomena identified in the literature as affecting stocks of fish, including problems with total allowable catch (TAC), ecological hierarchy theory, r and K species, the Allee effect, scale and metapopulation structure, the need to... |

| There is increasing interest in privatizing natural resource systems to promote sustainability and conservation goals. Though economic theory suggests owners of private property rights have an incentive to act as resource stewards, few studies have tested this empirically. This paper asks whether private rights-owners were more conservative with respect to their management opinions than nonrights-owners in five Australian abalone (Haliotis spp.) fisheries. Multiple regression analyses were used to link opinions to demographic, economic, and attitudinal variables. In contrast to standard economic assumptions, nonrights-owners suggested more conservative catch limits than did rights-owners, confirming qualitative observations of behavior in management... |
