As part of the Namibian government initiative on sustainable resources development, the Ministry of Fisheries and Marine Resources strongly urges right holders to continuously engage in value addition and market diversification of their products in an effort to realise maximum returns on their products. The importance of being in line...
Globalisation in the retail sector is transforming food value chains by driving consolidation in the industry and extending supply chains across the globe. Globalisation enables retailers to benefit from economies of scale and cheaper production in foreign locations. However, food markets themselves are increasingly responding to local consumer preferences. In...
The natural estrogen 17β-estradiol (E2) is responsible for the endocrine disruption and also has potential effect on the reproduction of vertebrate. However, its effect on invertebrate reproduction has scarcely been studied. The present study was conducted to determine the effect of E2 on survival, egg production and egg hatch of...
The coastal fishery in French Guyana is a challenging case study for the implementation of the ecosystem based fishery management. Although the current situation of this small scale fishery could be considered as satisfactory, the viability of the fishery can be questioned. Indeed according to demographic scenarios, the growth of...
This paper presents a new bio-economic simulation model for the Italian fisheries developed as a part of a project financed by The General Directorate for Fisheries and Aquaculture (under the Italian Ministry of Forestry and Agriculture Policies). The main objective of the model is to measure the effects of different...
This study is aimed at evaluating the effectiveness of buyback program implemented last during a 10-year period using a bioeconomic model. Aggregate fisheries stocks are assessed by the surplus-production model and standardized aggregate harvest function is used in the bioeconomic model. The simulation result indicate that the fish stocks are...
The West Coast Rock Lobster fishery is Australia's most valuable commercial fishery. Around 550 vessels
harvest 10,500 tonnes of lobster per annum. The industry has an enviable track record of biological
management which has been based on a variety of input controls. In recent years this has necessitated three
significant...
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...
Scallop fisheries are often characterized by variable abundance and periodic mass mortality occurrences. Area rotation is a respected management tool for sedentary species. A bioeconomic simulation model that incorporates the spatial and temporal distribution of scallop beds and fishing effort is presented. The model is user-friendly and was designed for...
The objective of the paper is to briefly present a comparative analysis of trends in the characteristics of
selected European fleets, observed over the last fifteen years, as an introduction to three empirical studies
of the behavioural determinants of these trends. The analysis presented aims at (i) describing changes
observed...
On 26th December 2004, colossal waves known as tsunami engulfed the coastal nations around the Indian
Ocean. The disaster brought physical, psychological and emotional suffering beyond measure to many
communities. It resulted in immense devastation of many coastal vegetations and marine ecosystems. The
fisheries in the coastal villages in Sri...
Generalised linear estimation and multi-layer perception neural network modelling techniques were applied to the Scottish trawler fleet data in order to estimate which inputs have the greatest impact on boat profits and output. Both produced comparable estimates that revealed inelastic and non-linear response to vessel power and length, negative response...
We focus on problems of access to marine sites for aquaculture in different countries, particularly in Maine, U.S.A. and Canada. The main question examined is how public natural goods (marine space) are allocated for aquaculture activities. Using ideas from law and economics, as well as institutional economics, we looked at...
Complex social–ecological systems such as small-scale fisheries require the inclusion of human dimensions in fisheries management and planning for simultaneously preserving human health and habitat health.However, linkages between ecological, social, political and economic subsystems have been largely ignored in conventional fisheries management, in Nigeria in particular. Hence, the weak governance...
This paper discusses sustainable development of Yemeni fisheries towards achievement of Millennium Development Goals (MDG) and stakeholder aspiration. Yemen is considered a Least Developed Country ranking 148 among 174 countries in terms of the Human Development Index. In terms of food security, Yemen is classified as a Low-Income and Food...
The harvest technology of several multispecies fisheries has been explained in the recent literature using dual-based models. These studies are useful for explaining rent dissipation, estimating input and output elasticities, as well as describing other aspects of fisherman behavior. Most of these analyses have assumed that inputs are fixed at...
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...
This paper proposes a formal analysis of the discarding issue including the sorting labour costs. Empirical evidences from an application to the Nephrops fishery in the Bay of Biscay show that sorting is an important time consuming activity on board and a factor of discarding. However existing literature does not...
For three years, a multidisciplinary group of researchers in social sciences, has analysed the Ethical, Legal and Social Aspects of fisheries management in Europe. In the framework of this ELSA Pêche programme funded under the ELSA line of the FAIR research programme of the European Commission (DG XII, Research), a...
A principle U.S. fisheries management concern is ensuring compliance with Endangered Species Act requirements to limit incidental takes of listed species to levels which do not result in potential jeopardy to existing population stocks. Part of the risk assessment process involves an analysis of historic takes (bycatch) of ESA-listed species...
The aim of this paper is to assist teaching undergraduate students how to analyse the issue of fish stock investment. The mathematical prerequisites are a basic knowledge of calculus. Both discrete and continuos time frameworks are used. To fish down or to build up a fish stock takes time, and...
The fishery cooperative association of Akita Prefecture closed the sailfin sandfish Arctoscopus japonicus fisheries from 1992 to 1994 to rehabilitate the stock. Following the temporary closure, the total allowable catch (TAC) has gradually increased. The aim of this study is to evaluate the effects of the fishery moratorium and other...
This contribution employs a „fish chain‟ approach or ocean to plate analysis to examine key market drivers affecting Northern Gulf cod fisheries recovery since their collapse in the early 1990s. Drawing upon the backward bending supply model of fisheries; secondary data was compiled and analyzed for the pre- and post-collapse...
Coastal nations can impose conditions of use on foreign fishing firms that operate in their Exclusive Economic Zone. We develop a game-theoretical model in which a fishery owner maximizes the revenue that it collects from firms that operate in its EEZ by charging them a fishing fee. We find that...
The high ecological, social and economic value placed on Western Australia’s aquatic environment creates a significant obligation on the WA Department of Fisheries to develop and implement appropriate and sustainable resource management strategies for the State's fisheries and fish habitats. Historically, fisheries management in Western Australia has been based on...
Sustainable aquaculture can be achieved when risk and uncertainly are incorporated in the analysis of the activity. This paper presents a precautionary approach to the feasibility analysis of a project for a commercial hatchery, applying decision theory. Two production scenarios were assessed, continuous and periodic, the later a combination of...
Recent work in the domain of fisheries ecology has shown that major changes are occurring in fish
communities exploited by commercial fisheries. Selective fishing pressure on more highly valued
components of fish communities, and its indirect effects via trophic interactions, are amongst the key
factors proposed to explain these changes....
Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management
indicators tied to outcomes described in management plans or on the achievement of a single objective such as an
increase in the size or number of older, more fecund female fish in a protected...
Algal beds are a key component of coastal ecosystems. In terms of inshore fisheries, algal beds are important as: spawning grounds for fishes; habitats for fry; and sources of small prey animals for fishes. To maintain robust fish catches, it is considered worthwhile to maintain the functions of algal beds,...
Nearly 75% of the stocks in the waters of the European Union are overused. Therefore, recovery programs
are both necessary and urgent. However, the decisions made by the fisheries ministers rather seem
to prolong the overuse situation instead of putting an end to it.
From an overall perspective, it would...
In this paper we define the regulatory structure of the New Zealand Quota Management System (QMS) and document key changes in its operation over time. We document the relevant legislation that affected the quota market from the Fisheries Act 1983 forward. We describe how the QMS operates in New Zealand...
The aquaculture sector is uniquely placed to complement production from the stagnating capture fisheries sector and it has advantages in terms of controllable production characteristics. However, aquaculture poses undeniable economic, environmental and social challenges that may be poorly evaluated or inadequately addressed within current policy frameworks. In such cases, the...
Unfortunately, most of the stocks are damaged by natural disasters or human activities and rebuilding the
stock are urgent requirements. Until now, in the stock management, some policies are commonly believed
to valid but have not been confirmed. A simulation model of the population dynamics incorporating
uncertainty has been already...
A balanced development between economic activities and environmental concern are profound in public and emphasized by the government policy. It is especially so with the change in working policy, thus the increase in leisure time for Eco-tourism. All along, fishing industry and marine based tourism have been major industries in...
It is widely accepted that in sea bottom areas where there is a scarcity of rocky formations and declining marine fish due to fisheries pressure, the deployment of artificial reefs (ARs) is a possible way to mitigate the problem. If ARs have an ecosystem-based fisheries management goal that means their...
Earlier this year a White Paper from the Norwegian Minister of the Environment presented a new, holistic, area-based management plan for the Norwegian part of the Barents Sea, including the Fishery protection zone around Svalbard. The plan will provide guidelines for managing human activities in relation to their use and...
Eco-labeling has been touted as a way for consumer preferences for environmentally benign products to be transmitted in markets. The label, as the argument goes, provides information to consumers who may then pay a price premium for the labeled products. Producers view demand for the eco-labeled products as quality differentiated...
To ensure the long-term conservation and sustainable use of straddling fish stocks, the 1995 United
Nations Fish Stock Agreement calls for the establishment of regional fisheries management organizations
to manage such stocks. This paper studies the potential for cooperation in straddling stock fisheries when
the cooperative coalition of countries acts...
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...
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,...
A study was conducted to understand current practices of commercially important marine fish marketing systems in the Patuakhali area of southern Bangladesh. A total of ten commercially important marine fish were identified such as: 1) hilsa, 2) pomfret, 3) marine catfish, 4) tuna, 5) coral fish, 6) marine eel, 7)...
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...
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...
The purpose of this article and presentation is to present an overview of the value-chain analysis project on international fish trade and food security with an impact assessment of the small-scale sector.
