Spatial structure and informational asymmetry in the economics of multiple stock renewable resources
… uncertainty inherent in the catch composition in multispecies fisheries, for example, has been largely ignored by the literature, though it has important implications for the efficacy and relative merits of different types of regulation. In this dissertation, I present two papers which extend the …

Identification and incorporation of quantitative indicators of ecosystem function into single-species fishery stock assessment models and the associated biological reference points
The move towards an ecosystem approach to fisheries management requires baseline information on the biotic communities and an understanding of the interactions among species. The two objectives of this study were to describe the demersal fish community (DFC) associated with the northwestern Gulf …

An exploratory approach to social impact assessment of public policy decisions: Multiple stakeholders perspectives on the social impact of overfishing in New England groundfisheries in the 1990s
… and collapse of the New England groundfish fisheries in the 1990s.</p><p>To enact a fisheries management plan amendment, Environmental Impact Statements (EIS, which include an SIA) must be submitted. Agencies use SIA guidelines to carry out such assessments but relatively few scientific …

Roads, Rights, and Rewards: Three Program Evaluations in Environmental and Resource Economics
… to a very different question: does rights-based fisheries management increase fish prices? Rights-based management, specifically “catch shares,” is known to extend fishing seasons by slowing the destructive “race to fish.” This reduces fishing costs. It may also increase fishing revenues, because …

Approaches to assessing the status of nearshore and estuarine fish and fisheries and their responses to environmental change
In multispecies fisheries knowledge, personnel and funding limitations often create the dilemma over which species should be the first to receive management and research attention. This thesis uses a Multi-Criteria Decision Analysis approach to prioritize 176 South African linefish species on the …

Flood pulse influences on exploited fish populations of the Central Amazon
Seasonally fluctuating water levels, known as flood pulses, influence the population dynamics and catches of fishes from river-floodplains. Although different measures of flood pulses, here called flood pulse variables, have been correlated to changes in catches of river-floodplain fishes, the …

More Value From the Same Fish: Catch Shares, Fishing Behavior, and Revenues
… goals (e.g., biological targets in fisheries). However, these policies remain quite controversial and are even opposed by some of the very same stakeholders who would stand to gain some of these property rights. In fisheries, this issue has an additional dimension that has not …
