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...
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...
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...
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...
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...
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...
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...
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...

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...
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...
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 modern times. This may soon change due to the recent establishment of a long-absent water quality monitoring program required...

Pelagic fishers operate in a dynamic environment and are faced with a high level of uncertainty on a daily basis. To cope with this complexity, fishers often rely on sharing information with others in order to improve their decision making. Yet previous research has not explicitly investigated the effect of...
Tilapia is the world's most popular aquaculture species farmed mostly in earthen ponds. Experience in China (the largest tilapia farming country) is used to develop and calibrate a bio-economic model on intensive tilapia pond culture. The model is used to simulate the impacts of climate, technical and/or financial factors on...

Whatever the quantity and the rate of water utilization is, economic principles indicate that there will
always be other water utilization methods which might increase the efficiency of the use of this resource.
Due to the geo-climatic position of Iran, this country finds itself in a water deficit situation as...
Vietnam is in the club of countries gifted with the long coastal line, and strong in marine features accordingly. Fishing operations are artisan characteristic and the management method is primarily open – access. Since the past few years, the yellow fin tuna long- lining fishery has become one sub-sector experiencing...
The incorporation of fisheries commodities into the International Food Policy Research Institute’s (IFPRI) International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) model suggests that demand for fisheries products will rise faster than supply over the next two decades, and that fishery commodity prices will rise relative to...
The concept of compensatory mitigation is well established as an approach to environmental management. In the past, mitigation programs have been used to conserve wetlands affected by development, and is proposed as a cost-effective approach to offsetting greenhouse gas emissions through reforestation programs. The concept may be equally applicable to...
