In this paper we analyse different econometric procedures of technical efficiency to estimate fishing capacity. These procedures are then applied to the purse seine fishery located in the Gulf of Cádiz. The target species of this fishery has changed quite a lot over the past few years. It used to...
Since the collapse of the Newfoundland groundfishery in 1992, the snow crab fishery has become Newfoundland’s largest fishery, accounting for approximately half the value of total landings. This study uses trip log data to estimate the production frontier and the technical efficiency of this fishery using a Stochastic Frontier Analysis...
Marine scientists and stakeholders are increasingly advocating ecosystembased
fishery management (EBFM). However, the way to operationalize
such EBFM remains controversial. The viability approach can be a relevant
modelling framework for EBFM as it accounts for dynamic complexities,
uncertainties, risks and sustainability objectives balancing ecological,
economic and social dimensions together with...
An investigation was carried out on Lake Geriyo in the month of April to know the pattern of
fish exploitation. The fish species sampled were mainly by using canoes as they were landed at
the landing site of the lake. A total of fourteen (14) species of thirteen (13) families...
After joining the WTO, easier access to Taiwanese market due to tariff reductions and deregulation of import restriction is expected to have substantial impacts on the fishery sector in Taiwan. Comparing to the tariff rates in 2001, the average tariff rates of fishery products will decrease 35.5%, in 2004. Especially,...

Vietnam’s marine fisheries are in need of knowledge-based management. This necessitates the establishment of
reliable indicators, which in turn entails a good data collecting and processing system. To bridge the gap between
specific requirements for fisheries policy development and the limited resources available, we have conducted a
study on costs...
Vietnam’s policy is to shift the fishing pressure from onshore to offshore water since the coastal resource has been overexploited, and a programme for investing in offshore vessels has thus been implemented since 1997. The question raised is whether the offshore fishing fleet is profitable and efficient or not? This...
Self-management has been recognized as important in successfully governing the common pool resources. This is no exception in fishery. Fishery cooperatives, where fishermen collectively manage the fishery, are garnering much attention from both regulators and academics. In this study, we aim to empirically disentangle the efficiency mechanism of pooling system....

In most of the coastal countries, the fisheries enable to satisfy multiple socio-economic needs such as food safety, public receipts, employment and so on. It is especially true in many coastal developing countries where fisheries constitute a considerable source of food and incomes. However, the strong pressure on the fisheries...
40 years ago the Atlanto-Scandian herring stock collapsed with severe consequences for Iceland´s monotonic economy at that time. Two years ago the international credit crisis brought the country´s largest banks to insolvency, which shocked the whole economy with butterfly effects in neighbouring countries. The paper begins with an overview of...
Situation: UK scallop fishing is input measures, with effort limits applied to >15m vessels only. There are no output limits. Industry members noted a decline in profits, and suggested that the effort regime was to blame. Government asked for evidence to support the claim and asked Seafish for economic analysis...
Pantar Island's coastal communities like many other coastal communities in eastern Indonesia have a high dependency on marine resources for income, food security and other benefits. Fish products (comprising several species of demersal and pelagic species) are particularly valuable (in addition to other products harvested and traded for export markets)...
An ITQ scheme has been shown to create a quota induced incentive for discarding of fish in excess of what is socially optimal. This finding is corroborated by empirical evidence in several ITQ managed fisheries. The incentive for discarding, over and above those expected in an unmanaged or input controlled...

Many species of wild fish continue to decline or remain significantly below target levels...
Illegal, Unreported and Unregulated (IUU) fishing is a pervasive practice in small scale fisheries. It affects the ecosystem and the livelihoods of people depended on the fisheries resources. Many times management technical measures from development partners and government have been implemented without success. In this study, we apply governability framework...
Assessing distribution of the expected bio-economic impacts of
management measures between fleet segments is a main issue for decision
making in fisheries management. This requires as a first step a good
description of the system and of the interactions between fleets through
stocks. Making this assessment operational also needs flexible...
Over 11 % of total population engaged in fisheries and aquaculture and out of them about 10% is women in Bangladesh (DOF, 2013). Thus, women make essential contributions to local food security and in many cases; they take part in the commercially fishing production and trading too. There are pervasive...
This paper examines the circumstances under which farmers respond to the introduction of tilapia production technology, and analyzes the manner in which the benefits from such introduction are shared and distributed among recipients. The hypothesis that the inverse relationship between yields and operational land size widely observed in agriculture is...
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...
The assessment of data-limited fish stocks is crucial for the sustainable management of marine living resources. Dependent on the scope and type of available data, a range of assessment methods are available, such as catch-only, length-based, or catch and survey-based methods. However, these methods suffer from several shortcomings, such as...
Worldwide, the scientific community and international organisations have
gradually agreed on the need for an ecosystem-based approach to fishery
management. However, the practical implementation of such an approach
faces huge problems, especially in developing countries where current
fishery management systems are generally weak.
One way to improve a fishery management...

Cohorts selected for the present analysis were women born between 1951 and 1966. Survey questionnaires were mailed to...
Over the past 30 years, fisheries management on the west coast of the United States has undergone a rapid evolution. Starting with very limited management and stock assessment techniques, the complexity of fishery models and size and breadth of fishery data sets have gradually increased, which has coincided with increasingly...
Biologists have criticized traditional biomass models in fishery economics for being oversimplified. Biological stock assessment models are more sophisticated with regard to biological content, but rarely account for economic objectives. Recently, age-structured models of fish stocks have increasingly been used in fisheries economics, but applications have so far mainly been...
Fishing overcapacity has lead to unsustainable harvesting and rent dissipation in global fisheries. Only government intervention of some kind can lead to a reduction in capacity. If efficiency is the primary objective for the regulator, then the least efficient vessels should be decommissioned. Here we analyze the Swedish fishery using...
This paper deals with the application of a dynamic model, combining Transaction Cost Economics (TCE) and Penrose’s theory of the growth of firms, under the New Institutional Economics (NIE) terms, to analyze and manage the “Agribusiness Innovation System” (SIE) coordinated by an agricultural research-development (R&D) organization in Brazil – Embrapa....
U. S. agriculture is at a crossroads. The value of traditional agricultural exports has fallen while imports have increased.

Since October 2013, consecutive cases of food mislabeling, such as Black Tiger Prawns being sold under the name of Kuruma Prawns in famous restaurants, department stores, etc., have begun to surface in Japan, and this has become a social problem. This study conducted a consumer questionnaire in free-answer format in...
Japan is both the largest producer and consumer of tuna in the world. However, Taiwan has been a major exporter to Japan of Thunnus albacares and Thunnus obesus recently. For example, the market shares of Taiwan's supply are 20% for T. albacares, and 44% for T. obesus in 1992. Hence,...
Closed areas are often used as either temporary or permanent measures to reduce fishing pressure on stocks. A major concern, however, is what happens to the effort that was previously employed in these areas. When modelling the potential impacts of the closed areas, it is necessary to model changes in...
Ecolabelling has become an essential component of the global sustainable seafood trade. The MSC is currently the world leader in certification and ecolabelling programs for wild capture fisheries. While the environmental benefits of certification have been widely recognised, its economic benefits are often anecdotal or unknown. The South African hake...
The Leptobotia curta, known as the Ayumodoki in Japanese, is a Japanese endemic freshwater fish that has been designated as a national treasure since 1977. This fish is, however, categorized as a "critically endangered species" by the Ministry of the Environment's Red Data Book in Japan. While a direct reason...
Because of the stagnation of commercial landings, the development of aquaculture activities is expected to rise during the next decades to match the growing demand for fisheries goods. Overall, it is often expected that the aquaculture sector could reduce to a certain extent the pressure applied over wild stocks. However,...
Seafood is a staple for most Sri Lankans and the country is a net importer of seafood, because of the
heavy consumption. Tsunami has had crippled the Sri Lanka’s main protein supply system and
thousands of others in marketing chain lost their jobs. The main focus of the study was...

The interpretation given to WTO agreements by successive Panels and Appellate Bodies has provided guidance regarding how such measures...
Economic indicators are needed for future knowledge-based fisheries management in Vietnam. This entails a good data collecting and processing system. This paper contributes to this requirement for the tuna-mackerel gillnet fishery, near-shore and offshore, in Nha Trang, South-Central Vietnam. For 2005 and 2006 fifty vessels were surveyed for technical characteristics,...
Non-market valuation research has produced value estimates for over forty threatened and endangered (T&E) species, including mammals, fish, birds, and crustaceans. Increasingly Stated Preference Choice Experiments (SPCE) are utilized for valuation, as the format offers flexibility for policy analysis and may reduce certain types of response biases as compared to...
The Constitutional imperative in South Africa after 1994 was to build a just and equitable order that would benefit its entire people's after centuries of social and legal privilege benefited ruling minorities. In
1998 new era fisheries legislation aimed to redistribute fishing access rights and reform the sector. The challenge...
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...
Two economic base analysis techniques that identify and measure
commercial fishery dependency at the local level are compared. The most
common method, the location quotient technique, uses direct metrics of
economic activity (sales, employment, wages, or value-added) to compare
a local economy with a reference economy. We compared this technique...
The paper is the first attempt to explore the ecological and economic impacts of genetic interaction between farmed and wild salmon over generations. An age- and stage-structured bioeconomic model is developed. The biological part of the model includes age-specific life history traits such as survival rate, fecundity, spawning success for...

According to nutrition based indicators, 50% of Indias population is
estimated to be below poverty line with inadequate nutritional intake.
Though majority of Indian population derives its nutritional requirement
from plant sources, there is a need to include animal proteins according to
nutritionists. In India, animal protein costs much more...
Concerns about declining stock and profitability in the Tasmanian rock
lobster industry led to the introduction of individual transferable quota
(ITQ) management in 1998. In this study, fisher groups were categorised
by effort and quota ownership traits to examine response to revised
management, and how profit drivers moderated this change....
The coastal zone is a dynamic area surrounding the interface between land and sea. The coastal area and its resources offer great benefits and opportunities for human use. Most coastal activities in Tanzania rely on the natural resources that the coast offers (fishing, forestry, agriculture, tourism, mining, salt production mariculture...
The geoduck fishery in British Columbia has been managed by individual quotas since 1989. Individual
quotas have fostered a co-operative management approach in the fishery, which is implemented through a
non-profit society with membership made up of licence holders in the fishery. This non-profit society, the
Underwater Harvesters Association (UHA),...
The US Magnuson-Stevens Act authorizes the use of onboard observers to
monitor commercial fisheries catch and bycatch (PFMC 2003). A question
of concern in implementing an observer program is that of the appropriate
level of observer coverage. Current practice varies by fishery; for example,
the California-Oregon drift gillnet fishery for...
A community based sea urchin (Tripneustes gratilla) culture was chosen as an alternative livelihood by
fisherfolks of Nalvo, a fishing village along the South China Sea in Sta. Maria, Ilocos Sur, Philippines.
The sea urchin culture was adopted among fishermen to augment their rapidly declining income from
fishing. The said...

The paper outlines the critical importance of managing marine resources for small islands countries of the Pacific and focuses on the role that women can play towards achieving sustainable fisheries.
The paper looks...
A two-stage, distributionally neutral and efficient rationalization policy design—one that preserves the ex
ante wealth distribution—is developed by blending elements of a cooperative and a partnership. It is
formally proven that there is no impediment to win-win rationalization using only IFQs allocated only to
harvesters. The design creates a bilateral...
Among the questions that ecosystem-based management raises for economists is how to partition uses of the many biological, chemical and physical attributes of marine ecosystems into sets of property rights that undergird total ocean wealth. An elemental basis of property rights for fisheries involves the interplay between ecological and technological...
Fisheries worldwide continue to suffer from the negative consequences of open access. In 1986, New Zealand responded by establishing an individual transferable quota (ITQ) system that by 1998 included 33 species and more than 150 markets for fishing quotas. We assess these markets in terms of trends in market activity,...
Many experts have argued that the traditional management of commercial fish stocks as single-species is short-sighted, wasteful, and ineffective. Ecosystem-based fisheries management (EBFM) now is being promoted as a potential solution to the problem. While much attention has been directed recently at the potential benefits of implementing EBFM for commercial...
An inverse system framework is followed in this paper to analyse the process of price formation in the Sydney Fish Market for the quota species of Australias South East Fishery.

In response to growing concerns about illness and deaths associated with Vibrio Vulnificus, California initiated a program in March 1991 that required anyone selling oysters to notify potential consumers that the “consumption of raw oysters can cause serious illness and death among people with liver disease, chronic illness, or weakened...
A dynamic game model is used to predict the strategic behavior of harvesters engaged in a non-cooperative fishery on a common property resource. The model predicts that an increase in the current number of harvesters in a common property fishery will reduce both the equilibrium harvest level and the current...
In the Philippines, the current licensing policy for commercial fishing does not significantly contribute to the general goals of fisheries management. It is a failure as a monitoring tool as evidenced by the absence of a comprehensive information system on fish catches, effort and area of operation. Fisheries licensing does...
This study examines income generation potential and resource- use efficiency of aquaculture farms in Nigeria. A total of 120 aquaculture farms were sampled. Using gross margin (GM) analysis, the result shows that, all the sampled farms were able to cover their total operating expenses with an average GM > 200,000...
If the spatial and temporal distribution of resources is not homogenous it creates an assignment problem. While the adoption of individual (or transferable) quota management in many commercial fisheries has resolved issues of over-appropriation, assignment problems may remain due to the spatial and temporal complexity of fisheries resources, which creates...
In many fisheries, harvesters of different scales, different gears, or on
different sides of political boundaries crossed by a single stock are
effectively managed separately. The New England Multispecies
(groundfish) fishery is about to dramatically expand the number of
management systems in place concurrently, by allocating portions of the
total...
For the past decades, around 20% of the natural coral reefs were lost and > 20% more is currently deteriorating. Due to the recognition of positive impact to fishery resources enhancement by artificial
reefs (ARs) deployment, Taiwanese government has started deploying ARs as a measure to improve the environment of...
Marine recreational fishing (MRF) is a leisure activity and a cultural ecosystem service that, beyond the welfare obtained by its practitioners, has an interesting potential to boost maritime economies. However, it does not represent a formal sector on the national accounts and, in Europe, it lacks a systematic and common...
Context and objective: Beyond leisure and food (sea ES) → MRF boosts maritime economies, but not a formal industry in our economic accounts. EU DCF → increasing focus on MRF, to be considered in commercial fisheries management decisions (CFP). Limitations of traditional approaches (aggregated expenditures,non‐market microeconomics) to assess MRF economic...
The small scale fisheries are generally unknown over the world due to a crucial lack of data, and particularly costs and earnings data. This is also true for the European fisheries while vessels less than 12 meters represent almost 75% of the total European fleet. Faced to the increasing price...
While indicators and assessment frameworks are being developed for ecosystems, and tools for determining the economic status of a fishery are readily available, integrated assessment tools are still mostly lacking. However, the development of an ecosystem approach to fisheries management requires the monitoring and assessment of exploited ecosystems in all...
