In this paper, a three-country dynamic bio-economic model is presented and used to simulate catch levels, stock size and profit potential of alternative management strategies for the Norwegian spring-spawning herring fishery. Management of the herring fishery is complicated by the migratory behaviour of the species moving between coastal state zones...
When attempting to mitigate the environmental impacts of a fishery there are typically multiple criteria
against which the performance of any measures can be assessed. If the gains are non-commercial (i.e.
non-market) in nature, formally determining how well measures perform becomes more difficult. This study applies the analytic hierarchy process...
Aquaculture remains as a suitable avenue in India for augmenting fish production, which is easy, cost effective and sustainable at the same time. It provides livelihoods to rural people through generating income and employment and reduces poverty by developing and strengthening community based approaches. The expansion of farmed fishery development...
The contribution of aquaculture development to the Vietnamese national economy and to farmers’ incomes has been documented in various government reports as well as working papers produced by development projects. However, the role of aquaculture in the life satisfaction of poor farmers has not been considered rigorously. In particular, it...

There are many livelihood activities as fishing, aquaculture and farming. Aquaculture systems are diversified:...
Tilapia culture in Yucatan State, Mexico, is largely semi-intensive. The producers are mostly poor farmers who receive government subsidies for purchase of fingerlings and balanced feed. Feeding practices are often inadequate (satiety rations), moreover, producers frequently suffer financial and resource shortfalls. During feed shortages producers are known to use empirical...
Capture-based aquaculture (CBA) is an industry that utilizes wild-captured specimens as stocking animals for ongrowing or storage. This yields an intriguing direct link between capture fisheries and aquaculture of these resources. Examples of CBA are collection of early life stages of many crustaceans and adolescent tunas for grow-out in aquaculture...
This study focused on analysis of the influences of the Post-Tsunami Rehabilitation Programs on the socio-economic status of cage aquaculture farmers along Andaman sea coast, Thailand. The study also emphasized on the enhancement of the livelihood of the farmers. Data was collected by interviewing 164 farmers, who reside in the...
A post-tsunami economic analysis of cage culture along the Andaman Sea coast of Thailand was carried out in five provinces (Ranong, Phang-nga, Krabi, Trang and Satun) from September 2007 to February 2008. Two of the culture species normally raised in this area include sea bass (Lates calcarifer) and grouper (Epinephelus...
This paper comparatively examined resource-use and technical (TE) efficiencies of aquaculture farms in the Southwest Nigeria. A total of 160 farms were randomly selected from four states across the region. Econometric applications of the stochastic frontier models provide measure of the farm’s technical efficiency. The results of regressions specified for...
This study examines income generation potential and resource- use efficiency of aquaculture farms in Nigeria. A total of 120 aquaculture farms were sampled.

Following the introduction of the red drum Sciaenops ocellatus in the early 80_s in the Caribbean island La Martinique, farming techniques were set up and a small scale farming sector developed. The introduction of that fish species in Indian Ocean islands, la Reunion and Mayotte, allowed to start fish farming...
Most current models analyzing technology adoption are based on a function that assumes farmers make decisions upon utility maximization but ignores cultural or social factors. The traditional production systems of the Mekong Delta were based on floating rice varieties and fish harvested both from rivers and rice fields. Since 1980...
In the last 30 years the Chinese Aquaculture Sector has become one of the most rapidly developing areas within Chinese Agriculture. The total output of aquaculture products (more than 51 million tons) has placed China as the world’s largest producer of aquaculture products since 1990, with more than 70% of...
Over the last four decades, the aquaculture sector especially in developing countries has experienced dramatic growth. The increase in aquaculture production is a combination of area expansion and technological change (enhanced strains, input of feed and fertilizer, and improved management). One example of such technological change is the selective breeding...
Promoting shrimp culture industry is one of the effective ways to earn foreign currencies and reduce rural
poverty for developing countries. However, there is a question if rising wage rates might be a constraint for further development. Thailand, for example, has established a firm position in the industry, but its...

About 27,000 fish cage culture operators in the Andaman coastline were affected by the tsunami impact, covering a total cage area of some 1,123,176 square...
The Western Central Pacific Fishery Commission (WCPFC) was inaugurated in 2004 after a preparatory process which commenced in 1996. Scientific advice is that skipjack stocks are in good condition, but bigeye and yellowfin stocks are being exploited too heavily and reductions of effort are needed to avoid overfishing. Compared to...
The potential for achieving sustainable and efficient harvesting of three species of migratory tuna in the
Western and Central Pacific Ocean is examined. The stocks reside in exclusive economic zones (mainly those of Pacific island countries) and in the high seas. Most harvesting is carried out by distant water fishing...
In the past several years, the fishing sector of the South Central Vietnam have been developing sharply, generating over 226 thousands employments. The sector has contributed a share of approximately 70% to the production value of the fisheries nationwide. The primary aim of this research paper is to assess the...
The fishery barometer surveys the economic prospects and trends of fishery enterprises in Finland. The barometer survey was developed on the basis of the general business surveys. The survey has been carried out annually since year 2000. Here we study if the results could be explained by external economic information...
Planning is an important kind of policies making. Meanwhile it is considered as activities which specify general development strategies of a nation, sector or even a specific field; it also is the basis for developing and implementing development projects (Huong, 2005). Therefore, it is essential to recognize the challenges, opportunities...
The shrimp fishery accounts for more than one-half of the total revenues generated by commercial fishing activities in the U.S. Gulf of Mexico. Due to its historical open access nature the harvesting sector has historically been overcapitalized (from an economic perspective) resulting in a suboptimal generation of rents. Various management...
In the past, Java island was known as “Java-dwipa”(a place where over-whelmed with food stock). However, due to over population, then food security became fragile including in fisheries sector. The such situation is worsen by economic and political turbulency in Indonesia.This study aimed to explore the level of fishers’s powerment...
Kattudel or stake net fishery is an ancient (from early 1950s) lagoon fishing technique in many regions of Sri Lanka. It drags special attention due to the absence of open access nature. The fishery is regulated by kattudel association stemming from the Catholic Church. In fact, the fishery has its...
This paper models and investigates the foreshortening of transferred quota which is applied in the Norwegian fisheries management. This reduction in the transferred quota amount by 20% is then redistributed amongst all vessels in the relevant vessel group. It is shown that fishing units can be expected to be operated...
This report presents the results of bio-economic assessment studies of the Bohai Sea & the Yellow Sea and the associated fisheries management. The studies, which were facilitated through workshop with the participation of international experts, included fisheries resources rent assessments and causal chain analysis to determine the rent losses in...
While there have been substantial benefits to fish trade and the fishing industry from the opening up of
markets, deregulation and greater flexibility in how and where companies can operate, this may have come at a significant cost when it comes to managing fish stocks sustainably. Globalization has facilitated the...
Norway has been characterized as a “hesitant reformer” regarding fisheries management. Instead of introducing a fully fledged ITQ-system after the crisis in the coastal fisheries in 1990, a new Individual Vessel Quota (IVQ) system was introduced. Later a structural policy was introduced, whereby fishing rights (and adjoining quotas) may be...
We estimated the economic rent obtained currently (that is, in 2002) in the Namibian hake fishery and the rent that might potentially be obtainable if the fishery were managed optimally in the sense of economics. We first reviewed previous economic and biological studies. We then used the theory and model...
During 1986-2006, fisheries in Tonkin Gulf had made rapid development. Total engine power increased 11.6 times while total catch only increased 2.9 times. Big increase in number of fishing boats has resulted to the overexploitation in near shore waters since 1995 and this situation has been spread out all over...
A debate is emerging over the extent to which privatization of fishery resources – private ownership and resource management without significant state oversight- is practical and socially desirable. What we term the “optimists” maintain that there are no effective limits to privatization and that the decades old fear that privatization...
Despite potential advantages of rights-based management over competitive fisheries, there has been significant political resistance to rights-based management from many fishermen, which has slowed the
adoption of rights-based management. This paper explores the concept of voluntary transitions to rights-based
management, under which fishermen may choose between an allocated fishery (with...
The fishery resources in the Gulf of Thailand have been subjected to excessive levels of fishing effort since perhaps as long as two to three decades. This has caused a change in catch composition with a higher share of short-lived species. The influence of this change on the value of...
About 8000 fishers are operating today in the Lake Nasser’s fishery (Egypt) and the annual official landing varies between 12,000 and 15,000 tons. Despite this relatively modest importance, the Egyptian authority decided to embark in a reform of the Lake Nasser fishery in the early 2000s. The objective of the...
There has been a long-standing interest in local knowledge in fisheries research and management. Much of this interest has been in terms of how local knowledge can be interpreted scientifically and used by fisheries experts and managers. Local knowledge becomes the property of scientists, wrapped up in a format and...
Over fishing is one of the obstacles faced in managing sustainable fishery resources. Even though various management instruments to control fishery resources have been in place, most of the time these instruments are not effective to curb over fishing especially in developing countries where poverty in coastal communities is still...
Marine Protected Areas (MPAs) can be considered as one of powerful conservation tools of fishery resource management in the literature. However, due to continuing environmental awareness and mismanagement, the Philippine government has decentralized the power of legislation and management of its MPAs since the early 2000. This encouraged participation of...
