Fisheries co-management starts with the premise that stakeholders have the innate capacity to improve resource condition as well as the welfare of the society. If this is true, there is a need for rapid and substantial devolution of fisheries management institutions. The main purpose of this study was to examine...
This paper investigates the welfare effects of random closures in a fishery
operating under open access. At each point in time, a fishery is facing the
probability of an extreme event that impairs fishing activities but has no
direct impact on the fish population. Examples include massive blooms of
dinoflagellates...
In this paper we try to assess the welfare implications of the Tanzanian fisheries boom following from the increase in quantities and prices of the Lake Victoria Nile perch export primarily to Europe over the last twenty years. We have a micro level perspective using data from a 1993 World...
The paper will report on the development of a new set of wealth-based
Fishery Performance Indicators (FPI) for evaluating and comparing the
worlds fisheries management systems. A wealth-based fishery management
system is one that is ecologically sustainable, socially acceptable, and
generates sustainable resource rents or profits. The Fishery Performance
Indicators...
The spatio-temporal overlap of morphologically undistinguishable weak and healthy stocks is a major concern for the Pacific Northwest troll Chinook salmon fishery. Regular fishery closures have led to major financial losses calling for alternative regulatory measures. One approach for such complex and pressing socio-ecological challenges is the transition towards transdisciplinary...
Madagascar is the world, fourth biggest island, and
one of the world‚ poorest countries. Given its severe
poverty, Madagascar has no large-scale domestic fleet. Consequently, it is required by the United Nations
Convention on the Law of the Sea to rent these un-exploited resources to distant water fleets (DWFs)
from...
This paper analyzes the suitability of strong and weak sustainability assessment in the context of fisheries management. This topic is a main stream issue in the field of Ecological Economics, but its application to fisheries is rather ambiguous, although fisheries have been the focus of many pioneering studies related to...
Fisheries economics has recently earned a seat at the global fisheries governance table, with everything from subsidies, to high seas fisheries, to Indigenous rights, food security, and human rights now being open for global assessment. The papers in which these studies are housed are in high impact journals, are highly...
Inland fisheries in the Tonlesap Lake of Cambodia play an essential role in providing with protein and cash income to the poor around the lake. However, the fisheries face a crisis of fish resource depletion due to excessive catch, water pollution and decline in the water level of the Lake....
Recent aggregate models of recreational participation have largely focused
on demand systems and choice models utilizing cross sectional data. While
these strategies may be advantageous for the estimation of welfare
measures, they have left unexplored the relationship between recreation
participation and general temporal economic trends. This research shifts its
focus...
Vulnerability assessments play an important role in the climate change adaptation process in that they link physical changes (either current or projected) with the ability of aquatic and human systems to cope or benefit from such change. In general, a vulnerability assessment helps to target adaptation actions by better understanding...
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...
Quota management systems (QMS) provide faith-based incentives for individual quota holders to conserve the resource voluntarily; quota holders expect the system to work and to be enforced and their expectations are usually realized despite imperfect incentives and significant enforcement burdens. Even with QMS there is never an individual incentive to...
This article gives insights on the complex balance between coalitions structure,
resource state or dynamics and agents’ heterogeneity to avoid bio-economic
collapses. A model bringing together coalition games and a viability approach
is proposed to focus on the compatibility between bio-economic constraints and
an exploited common stock dynamics. It is...
This paper examines the viability of the management of a transboundary resource, the Bay of Biscay anchovy (Engraulis encrasicolus L.). A deterministic model is used to simulate the anchovy dynamics, with the fish stock consisting of two age groups, “young" and “old", while recruitment follows a Beverton Holt pattern. Two...
The paper presents a vessel level simulation model of the impact of a landing obligation on a typical Scottish demersal trawler under a discard ban in addition to existing quota management controls. The simulation model is based on a simple microeconomic model of firm behaviour and predicts landings, discards and...
The purpose of this article is to report the results of a statistical investigation of links in the fish supply chain in Uganda. We are particularly interested in the extent of ex-vessel prices impacting links downstream in the fish supply chain. We test for vertical and horizontal co-integration for five...
Fishery villages (Van Chai) has been formed for about 300 years since pioneered fishers settled in Phan Thiet for their livelihoods. This was a original social professional organization found before official administrative system established.
Binh Thuan has more than 30 Van Chai in coastal areas, in which about 20 importantly...
This study applied brand choice model and stated preference data collected in French context by means of choice experiment to investigate value of intrinsic and extrinsic attributes of various fresh seafood species. The estimated models show that the extrinsic attributes (i.e. product forms, production method, and product origin) and intrinsic...
A major problem facing the Seychelles is the decline in the quality and the value of marine protected areas (MPAs). Economic valuation can help guide policy makers to understand the value of marine resources and the cost of neglecting MPAs by expressing the value of their goods and services in...
The value of commercial fisheries is expressed in a variety of ways in marine policy development, implementation and in individual marine proposals and consent decisions. This presentation provides a fishing industry perspective on the experiences of the delivery of Marine Protected Area and marine planning policy and licensing in the...
The documentation of sustainability constitutes a significant opportunity for product value-adding in the captured fish sector, and a means of differentiating sustainably caught and landed fish from inferior alternatives. In the industry-owned R&D project WhiteFish the main objective is to create a tool for catch and processing SMEs in the...
This paper explores some theoretical and practical issues in developing policy for the management of shared fisheries for maximum value. Maximisation of value from the use of resources is a key component of sustainability, and transferable rights in commercial fisheries management have contributed significantly toward this goal. Maximising value becomes...
Although many countries develop dominating export conventions aimed
for strengthen the fishing industry export based economy, the export
performance varies. The institutional reasons for such differences in
performance are investigated in a comparative study of the Norwegian and
Icelandic export of salted cod to the Spanish market. Iceland has over...
Capture fisheries and aquaculture in freshwater bodies play a very important role and is considered to have great potential for augmenting fish production as well as diversification of livelihoods in both Cambodia and Vietnam. In Cambodia, inland fisheries remain primary importance in the fisheries sector, while aquaculture is more important...
Session #504 A Benefit-Cost Analysis using ratios of annual costs and benefits was calculated for fish farmers (aquaculture) and fish marketers (including distributors, processors and retailers). Forty five of the 86 respondents had a benefit cost ratio higher than 1. Further analysis investigated effects of selected variables on ratios. Relative...
The Spanish market for salted cod has undergone important transformations in recent decades. The collapse of the Newfoundland fishery dramatically reduced local processors’ access to the raw material, which previously was mainly supplied by Spanish vessels. The price of salted cod increased and processors margins decreased. By using price integration...
The value chain for the sea cucumber fishing industry in Sri Lanka was analyzed using the data collected by interviewing the main actors of the chain from February to December 2014. Divers, buyers, processors and exporters are the main actors in the value chain. Divers are the key upstream players...

La lagune de Nador se caractérise par un écosystème semi-fermé, en communication avec la mer par une étroite passe. Cet écosystème est sous l'influence de plusieurs facteurs externes tels que l'ensoleillement, l'apport en eau douce, les eaux de ruissellement, le lessivage des champs agricoles et les eaux usées urbaines. L'influence...
Illegal, Unreported and Unregulated (IUU) fishing activities are a threat for both the marine environment and society. By undermining effective management systems, IUU fishing activities not only generate harmful effects on economic and social welfare, but also reduce the incentives to comply with rules. The issue of IUU fishing has...
In the institutional framework of fishery management in Japan, which can be seen as a Co-Management system, fishermen's agreements are prerequisites for implementation of resource management measures. However, because of uncertainties in the effect of management measures, fishermen's agreements are difficult to obtain. This study applied a decision-making method under...
As fisheries management is increasingly required to consider the full impacts of their operations, this work seeks to define the relationship between fishing effort and interactions with listed endangered species. The study employs logbook data containing over 64,000 sets, matched with observer data from 2008 to 2015 in an undisclosed...
Given the fragile nature of fish stocks in the North Sea, it is of increasing importance to produce accurate and informed estimates of the state of stocks for the purpose of setting TACs. In order to do this, realistic and reliable estimates of fishing mortality and the current state of...
The development of several sub-fields of general economics, including those of bounded rationality, institutional economics and the evolutionary economics, has expanded the scope and intensity of the dialogue both within economics, as well as between economists and other scientists. One of the more important preoccupations of early evolutionary economics was...
Policy makers must ensure that regulatory frameworks contribute to the maintenance of resilient marine ecosystems. Recreational fishers add additional pressure on worldwide fish stocks to that exerted by commercial fishing, especially in coastal areas. Fishing tourism have an increasingly stronger presence in areas with growing numbers of permanent residents. Marine...
There is no doubt that policy makers must ensure that the different regulation frameworks contribute to the maintenance of resilient ecosystems that sustain healthy resources for commercial fishers, contributing to the economies that depend on their activity and supply markets with healthy products. However, marine recreational fishing also contributes significantly...
Though the basic purpose of MPAs is marine ecosystem conservation, the question of their influence on the local economy is often critical since it governs their social acceptability. This paper addresses the
problem of measuring the local economic impact of MPAs, on the basis of a comparative analysis of socio-economic...
This paper provides an overview of use rights, that sanction fishers, fisher groups and fishing communities to access and use fishery resources. The paper first reviews the various forms of use rights, ranging from access rights (territorial use rights and limited entry) to quantitative input (effort) and output (harvest) rights....
Britain has traditionally tried to protect its livestock, fish and shellfish production industries from many serious diseases by restricting imports of live animals- fish and shellfish to those from countries free of specified important diseases affecting particular classes of stock. Although the primary aim of the European Union has been...
In the summer of 2005, fishing began under a novel management program in the Bering Sea and Aleutian Islands crab fisheries. To protect processor and community interests, the program requires harvesters to land their catch with processors having historic participation in the fisheries. This requirement effectively prevents
processor competition for...
