In 2006, Viet Nam’s fishery sector contributed about 6.1 percent to the GDP of the country and the value of aquatic products in export turnover was about US$ 3.3 billion. This accounted for 9-10 percent of the country’s total export value (MOFI/USDAFAS, 2007). Home consumption of fish has increased from...
Fisheries are increasingly important in the world with growing demand for fish in China, Western, African and Asian countries. Many people depend on fisheries and will be benefited from fisheries. Many governments took fisheries promotion policies after the 1970s when the UN 3rd Law of the Sea Conference developed. However,...
Climate change may cause significant changes in the distribution, abundance, and species mix of commercial fishery resources. In any given area stocks of some species may decline; stocks of other species may increase; and new species may appear in commercially significant volumes. However, it is difficult to predict what specific...

Binh Thuan has more than 30 Van Chai in coastal areas, in which about 20 importantly...
This paper formulates a simple biomass growth model of a fishery. The property rights regime is of the unregulated local common property type with a fixed number of fishermen and where the fish stock is exploited in a myopic profit-maximizing manner. Within this resource management setting it is demonstrated that...
The sustainable yield function is a favoured tool in fisheries policy making. Normally, this function is drawn as a continuous curve in effort-yield space. This means that sustainable yield (harvest) is gradually reduced to zero as fishing effort increases. This, however, does not have to be the case. The sustainable...
The majority of monitored fish stocks globally is fully or over exploited, that is, at or below their maximum sustainable yield stock levels. Despite this resource situation international trade in fish products have been increasing for a long time. An export tax on fish and fish products, as an alternative...
Fisheries models are generally built to assess the dynamics of a resource with a given fishing mortality
which level can be decided by some “decision maker” and/or which can be an observed process, e.g. times series proportional to some observed values of fishing effort. In these cases, the resource dynamics...
Fishing for the life reef fish has been an important source of economy both at macro level and micro level. At Macro level, life reef fish for food (LRFF) plays a greater role in increasing export revenue since most of the fish are sold in overseas markets such Hong Kong...

countries by providing an important source of cash revenue. On the other hand, fish trade is...
Today, decentralization and democratic participation are presented as necessary conditions to achieve poverty alleviation and ensure the sustainable use of our diminishing natural resources. In small-scale
fisheries, similar ideas predominate and decentralization has become the new management paradigm through the concepts of community-based and co-management. In this paper, we present...
NOAA’s National Marine Fisheries Service (NMFS) recently completed two reports on excess harvesting capacity, National Assessment of Excess Harvesting Capacity in Federally Managed Commercial Fisheries and Excess Harvesting Capacity in U.S. Fisheries: A Report to Congress. This paper presents the definitions of harvesting capacity, excess capacity, and overcapacity used in...
When weak and strong fish stocks are caught in the same fishery, managing for the protection of the weak
stock may result in foregone economic benefits from harvest of the strong stock, while managing for the
strong stock may result in overfishing of the weak stock. A particular complication arises...
There is growing recognition worldwide that the impacts of fishing on non-targeted components of marine ecosystems should be included in the assessment of fisheries sustainability. This leads to the inclusion of new constraints in evaluations of the long-term bio-economic performance of fisheries. In this paper, we analyze the implications of...
Outputs and inputs during 1994-2006 in the USA Northeast Multispecies (groundfish) fishery—including days fished for a group of 47 otter trawl vessels fishing out of New Bedford, Massachusetts, USA—were analyzed to test the hypothesis that restricting the annual days-at-sea (DAS) of individual fishing vessels increased Technical Efficiency (TE). The results...
In many fisheries, the harvesting pattern shows considerable intra-year variation. These fluctuations give
challenges for downstream firms in value chains where predictability and continuity in the flow of production are important. Seasonal harvesting may well be rational from an economic perspective, as migration patterns can give huge variations in catch...
Under the reauthorized Magnuson-Stevens Act (MSRA), US fisheries management councils must specify an annual catch limit (ACL) for each managed species and institute accountability measures (AMs) to ensure that actual harvest will not cause the stock to be overfished. While the details of implementation are still being developed, a set...
In 2001, New Zealand modified its quota management system (QMS) to function as a hybrid ITQ/tax system. Catches in excess of annual catch entitlements (ACE) incur payments, called “deemed values”. The deemed value
system was part of the reforms that separated ACE from quota, which reduced transactions costs for both...
A key issue in fisheries restoration is the speed at which recovery can occur, while still meeting the
economic and social constraints which managers must deal with. This paper uses the viable control approach to examine fisheries restoration and study the tradeoffs involved with the selection of recovery strategies. We...
Fisheries management is complicated in nearly all fisheries by various types of uncertainty. Numerous economics and fisheries science publications prescribe adjustments to harvest strategies in the face of uncertainty. The conclusions and recommendations from this body of work are conflicting in many cases, are often dependent on critical but unrealistic...
