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