Skates are widely consumed across the globe, but many large species are subject to considerable concern regarding their conservation and management. Within Europe such issues have recently driven policy changes so that, for the first time, reports of skate landings now have to be made under species-specific names. Total allowable catches have also been established […]

Overfishing threatens coral reefs worldwide, yet there is no reliable estimate on the number of reef fishers globally. We address this data gap by quantifying the number of reef fishers on a global scale, using two approaches – the first estimates reef fishers as a proportion of the total number of marine fishers in a […]
Teh LCL, Teh LSL, Jumin R (accepted). Combining human preference and biodiversity priorities for marine protected area site selection in Sabah, Malaysia. Biological Conservation
High human reliance on marine resources in developing countries is a challenge for implementing marine protected areas, which usually seek to limit or restrict fishing in selected areas. Fishers’ spatial preferences should be considered during the site selection process, but biodiversity considerations are generally the primary focus. The Protected Area Suitability Index (PASI) is a […]
Teh LSL, Teh LCL, Sumaila UR (in press) Time preference of small-scale fishers in open access and traditionally managed reef fisheries. Marine Policy
Individuals with high discount rates are likely not partial to conservation because they are unwilling to sacrifice short term benefits for potentially higher gains in the future. Many reef fisheries worldwide are open access, and fishers under open access systems are theorized to discount the future at an infinite rate. In contrast, fishers in a […]
Teh LSL, Teh LCL, Sumaila UR, Cheung W (2013) Time discounting and the overexploitation of coral reefs. Environmental and Resource Economics DOI 10.1007/s10640-013-9674-7
The incentive to overexploit a fishery resource is thought to exist if the resource owner’s discount rate is sufficiently higher than the biological productivity of the targeted fish stock. Coral reef fisheries are extensively overexploited worldwide, but the discount rates of reef fishers are largely unknown, and there is little information about how discount rates […]
Sumaila, U.R. (2013) Game Theory and Fisheries: Essays on the Tragedy of Free for All Fishing. Oxford, UK: Routledge. 178 pp.
The book targets both economists and students of economics who are familiar with the tools of their trade but not necessarily familiar with game theory in the context of fisheries management.

“What distinguishes this book most from previous works is that [it] begins with a holistic, global-scale focus for the first several chapters and then provides an example of how this approach can be applied on a regional scale, for the Pacific region.”

Abstract: Tuna fisheries in the Western and Central Pacific Ocean are among the most valuable resources in the region. These fisheries, worth an estimated $4.1 billion each year, play a pivotal role in supporting incomes and development goals in the region. However, due to the twin, and potentially inter-related effects of harmful fishing practices such […]

Abstract: Amid declining shark populations because of overfishing, a burgeoning shark watching industry, already well established in some locations, generates benefits from shark protection. We compile reported economic benefits at shark watching locations and use a meta-analytical approach to estimate benefits at sites without available data. Results suggest that, globally, 590,000 shark watchers expend USD […]

Abstract: West Africa was identified as one of the most vulnerable regions to climate change in previous global analyses. Adverse changes in marine resources under climate change may pose significant threats to the livelihoods and well-being of the communities and countries that depend on fisheries for food and income. However, quantitative studies on the potential […]
