Sea Turtle Interactions with Hawaii's Longline Fishery: An Extended Multiobjective Programming Model Incorporating Spatial and Seasonal Dimensions

Creator:: Pradhan, Naresh and Leung, PingSun
Abstract:: Accounting for endangered and protected sea turtle interactions with the pelagic longline fishery by the fishery management has become an important policy goal recently. A multi-objective programming model for Hawaii's longline fishery that incorporated sea turtle interactions (Pradhan and Leung, in press, Ecological Economics) has been extended with spatial and...

Estimating Future Fish Demand

Creator:: Cai, Junning and Leung, PingSun
Abstract:: There are perennial efforts in forecasting future fish supply and demand (e.g. the IFPRI Fish to 2020 model, the OECD-FAO Fish Model and the WB-IFPRI-FAO Fish to 2030 model). A panel model is developed to estimate a country's fish demand in the future. Instead of using a country's' own historical...

Economic Impacts of Catch Allocation from Commercial Fishery to Recreational Fishery in Hawaii

Creator:: Sharma, Khem R. and Leung, PingSun
Abstract:: The recent expansion of the longline commercial fishery has heightened the conflicts among various fisheries in Hawaii, especially between longliners and non-longline commercial (troll and handline) and recreational fishing boats. The recent court ruling against longline fishing on some waters around Hawaiian islands may provide an impetus for the expansion...

Modeling entry, stay, and exit decisions of the longline fishers in Hawaii

Creator:: Pradhan, Naresh C. and Leung, Pingsun
Abstract:: A behavioral study on the entry, stay and exit decisions of the fishers in Hawaii's longline fishery was undertaken in a random utility framework by applying the multinomial logit (unordered) model. Pooled annual cross-sectional and time-series (1991-98) data were used. The empirical results confirm that the entry, stay, and exit...

Partial Harvesting in Intensive Shrim Culture: A Network-Flow Model

Creator:: Yu, Run, Leung, PingSun, and Bienfang, Paul
Abstract:: Theoretically, partially harvesting the standing stock of cultured species over the growout cycle to reduce competitive pressure due to increased biomass could enhance growth and total yield. There are several promising laboratory results and theoretical arguments on the potential of partial harvesting in enhancing the productivity and profitability of intensive...

Understanding the Contribution of Aquaculture and Fisheries to GDP

Creator:: Cai, Junning, Huang, Hui, and Leung, PingSun
Abstract:: The contribution of aquaculture and/or fisheries to Gross Domestic Product (GDP) directly or indirectly are essential indicators for policymakers to assess the sector's economic performance and make informed policies or decisions that can affect the level of political and financial support to the sector, and hence, its development pace. Despite...

Marketing Potential for a Locally-grown Oyster in Hawai'i

Creator:: Chen, Jessie, Haws, Maria, Fong, Quentin, and Leung, PingSun
Abstract:: While studies have long examined the economic viability of oyster industries along the Pacific and Atlantic coasts of the mainland United States, Hawai`i has had no industry to speak of in decades. The Pacific oyster, <i>Crassostrea gigas</i>, is being cultivated in a traditional Hawaiian fishpond for the first time, providing...

Ethnic diversity, social capital and the potential for co-managemet - a case study of Hawaii's longline fishery.pdf

Creator:: Barnes-Mauthe, Michele, Arita, Shawn, Allen, Stewart, Gray, Steven, and Leung, PingSun
Abstract:: Social networks and social capital can facilitate or constrain collaborative arrangements which can enhance resource governance and adaptability in complex social-ecological systems such as fisheries. Yet, the impact of ethnic diversity among resource users on social network capital in the context of resource governance has not been previously examined. To...

How to Measure Economic Impacts with Multiple Interacting Policies?

Creator:: Sweeney, Jonathan, Howitt, Richard, Chan, HingLing, Pan, Minling, and Leung, PingSun
Abstract:: We present a positive mathematical programming model (PMP) for Hawaii's longline fishing fleet with the aim of examining the outcome of specific fishery policies. This model expands an earlier model which developed a generalized adaptation of the PMP framework to study fisheries. The current model provides managers with a realistic...

Employing Pattern-Oriented Modeling Strategy in Developing Agent- Based Model of Socio-Economic Systems: the Experience From Hawaii's Longline Fishery

Creator:: Yu, Run, Pan, Minling, Railsback, Steven, and Leung, Pingsun
Abstract:: Pattern-oriented modeling (POM) strategy has been successfully applied to build, calibrate and validate agent-based models (ABM) in ecology. Instead of the traditonal modeling strategy that often requires comparison of the magnitude of model outputs to a selected set of observed responses, POM focuses on the ability of the model to...
