The paper predicts the outcomes of alternative management scenarios for the Southern Bluefin Tuna (SBT) fishery over the next twenty years. Two criteria are used to characterize outcomes: economic efficiency as measured by the present value of fishery rent generated; and conservation as measured by the predicted size of the...
Data scarcity and weak institutional governance make the implementation of top-down, quota-based fisheries management in much of the developing world’s fisheries difficult. An alternative to quota-based management is the use of space-based rights such as territorial use rights fisheries (TURFs). In spite of wide spread use of TURFs as a...
Non-radial measure of technical efficiency of fish farms in Oyo State was examined using Data Envelopment Analysis (DEA). Use of the non-radial measures to calculate overuse of inputs by inefficient fish farmers was demonstrated and the potential for reducing inputs used by improving efficiency was evaluated. Ordinary Least Square (OLS)...
Oregon ocean shrimp annual harvest relies on the successful recruitment and growth of age one shrimp. Changes in oceanic conditions appear to have major impacts on recruitment, spatial abundance and growth rates. Successful recruitment has been identified with the timing and strength of the spring transition generating oceanic conditions favorable...
In recent years, considerable attention has been given to the effects of removing trade restrictions on natural resource utilization and on poverty, especially in developing countries. Our paper adds to the growing body of conceptual work to show conditions under which a developing country that, in isolation, is unable to...
The status of fisheries resources on coastal and offshore areas is getting worse in Taiwan. Thus, to establish a fishery resources management system has become the main task among stakeholders. In this study, we would like to examine the feasibility of imposing the community-based co-management system and setting closed fishing...
A bioeconomic model allowing different degrees of harvesting closures for two sub-stocks consisting of mature and immature fish is presented. Hence the model opens for partial closures of fisheries on both sub-stocks. Migration between the two sub-stocks is defined as recruitment of the young to the mature sub-stock, and egg...
Organizers convened an international workshop to address training necessary to produce effective managers for 21st century fisheries. The workshop involved government, industry, academic, and nongovernmental organization (NGO) leaders from Oceania, North America, and Europe. They addressed vision and management challenges of 21st century fisheries; requisite skills and knowledge; current training...
This paper presents the results of the impact of the attitude and knowledge of the Bajau tribe in Nain Island of North Sulawesi, Indonesia, on the development of their fishery activities. The results are also compared with the same parameters on another community of the same Island, the Sangihe tribe....
The structure of global supply and demand for fish has changed dramatically over the past few decades. Traditional marine fisheries increased and reached its peak in the 1990s, while aquaculture has expanded rapidly since the 1970s, making it one of the fastest growing sectors in all of agriculture. Fish has...
