Electronic monitoring (EM) systems hold promise for the future collection of fishery-dependent data, either to supplement human at-sea observers or replace them. Several pilot studies have been conducted on EM in the New England groundfish fleet, though there are still on the water operational and shore-side protocols to further test...
Indicators of the economic performance of fishing vessels are frequently computed in many countries. Usually, measures of economic performance are based on the return on capital invested. However, several measures of capital value exist, according to the economic information available. In this paper, we use different types of information to...
This paper compares two methods for collecting data concerning professional fishing fleets economic performance : use of preexisting bookkeeping databases and ad hoc field surveys of fishers. Each method has its pros and cons and, for practical reasons, it may be necessary to make use of both. Such a feature...

In this paper, the estimate of the productive efficiency for some Italian fleet segments is proposed. The estimate is based on a Stochastic Frontier Production (SFP) function and a Data Envelopment Analysis frontier (DEA) using micro data of fishing vessels. The essential random nature of the fishing processes under consideration...
The fish market has a long tradition in economic literature. Many authors refer to it when they want to investigate the organisation of exchanges, whether from the point of view of equilibrium or disequilibrium. This market constitutes a kind of economic paradox in the sense that, in many cases, first...
Fisheries nationwide are facing major challenges that require collection of real time (RT) and near real time (NRT) information. High-resolution RT and NRT data are critical for addressing a variety of fishery needs including quota accounting, observer coverage, bycatch management, electronic logbook and fish ticket requirements, research and monitoring, spatial...
Overcapacity situations appear regularly in the activity of marine natural resource exploitation. The measure of capacity utilisation and allocative efficiency for fishing vessels is an approach that can determine the details of that overcapacity. On the one hand, DEA (Data Envelopment Analysis) methodology can be used in the case of...

The Training Department of the Southeast Asian Fisheries Development Center has completed a wide range of experimental fishing trials on the use of Juvenile and Trash Excluder Devices (JTEDs) over recent years. These trials have investigated the effectiveness of the rigid sorting grid, rectangular window and semi-curved window JTEDs in...
The structure of global supply and demand for fish has changed dramatically over the past few decades. Traditional marine fisheries increased and reached its peak in the 1990s, while aquaculture has expanded rapidly since the 1970s, making it one of the fastest growing sectors in all of agriculture. Fish has...
Rights-based fisheries management programs allocate to fishermen a specified portion of the annual TAC, providing fishermen with the incentive to optimize the value of this share, which has been shown to lead to more economically efficient behavior. Less efficient operators will tend to leave the fishery, decreasing overcapacity, but this...
Vietnam is the peninsular country and lying in the area of monsoon tropical climate therefore has very diversify and abundant and valuable fish resources. Since long time ago the fisheries resources in natural water bodies (as in dams, rivers, lake, canals, sea) have been concerned as common property (and is...
The artificial reef of Vilamoura (ARV) deployed between 1998 and 2001 is situated off the fishing community of Quarteira and the tourism resorts of Vilamoura (Southern Portugal). The reef extends for approximately over 4,000 m long and 1,400 m wide at a depth ranging from 20 to 40 m below...
The official catch records generally are carried out in the landing operations. There three categories of fishing that are not included in landings; illegal, unreported and unregulated catch (IUU) and are considered like lack of information. It is necessary, to consider these categories of fishing to know the true impact...
Prior to the introduction of the modern management regime, the concept of capacity constituted no other reference than the technical capacity of a given fishing vessel. However, after closing the commons and the introduction of a an heavily institutionalized management regime, the fisheries sector have been transfomed to complex web...
This paper presents an analysis of the collapse of the European anchovy fishery (engraulis) in the Bay of Biscay. The analysis shows that this crisis is a clear expression of general troubles facing the CFP and its an applied case of deliberations that are analysed in the Green Paper. In...
The White paper on European Governance suggests enhanced participation and transparency to improve policies, regulations and outcomes.

Modern fisheries management is strongly based on ecosystem theory. Ecosystem management involves direct manipulation of the habitat and population as well as human activity in order to optimize sustainable returns to humans. The ecosystems approach is widely viewed as a new concept in management of fisheries and aquaculture. Ecosystems based...
Ecosystems are one of the most productive fishing grounds in the world, with important commercial and valuable fish stocks. However, overfishing, IUU activities, discards, habitat destruction and alteration of the biogeochemical conditions of the ecosystem combined with an increase in fish demand continue to drive fisheries to an alarming situation....
The need for management of the marine ecosystem using a broad perspective has been recommended under a variety of names. This paper uses the term Ecosystem Management, which is seen as a convergence between the ecological idea of an organisational hierarchy and the idea of strategic planning with a planning...
The main objectives assigned to ecosystemic indices are to fuel the debate on the best ways to reduce the impact of global warming. Fishing activities are also concerned with the debate. The assessments carried out about fish products show that the use of fuel in the fishing stage has the...

Marine conservation measures such as moratoriums challenge the economics of fisheries. Efficiency of moratoriums depends on the acceptation by fisheries of such conservation measures. If the measure is unaccepted by fisheries the moratorium is not respected which leads the stock to extinction. The purpose of this article is to identify...
We study the combined effects of periodically varying carrying capacity and survival rates on the fish population in the ocean (sea). We introduce a new delay differential equation model with a control parameter which describes how fish are harvested.
We consider a predation function as the function of the delayed...
This research analyzes the effects that a redistributive fishing quota policy, within a collective rights quota assignment system, might have on the profits and employment of artisanal fisher organizations. The Chilean authorities have been pursuing a deliberate quota redistributive policy between ship-owners of different vessel categories. This policy has affected...
In this paper we study whether environmental bureaucrats share preferences for environmental policy with the general public. We use the choice experiment method to elicit preferences for improvements in coastal cod abundance along the Swedish West coast. This is done for the general public, Swedish EPA (SEPA) bureaucrats, and for...
In the 2002 CFP Reform, a potentially significant change that took place involved tentative steps toward increasing stakeholder participation if fisheries governance. Participation by the fishing industry (and conservation groups) in the management of fisheries is, in general, a positive thing. However, participation has many different ‘practical definitions,’ i.e. it...
Small-scale fisheries make key contributions to food security, sustainable livelihoods and poverty reduction, yet to date the economic value of small-scale fisheries has been poorly quantified. In this study, we take a novel approach by characterizing post-landing trends of small-scale fisheries resources and estimating their total economic value, including both...
The main instrument used in fishery management is the total allowable catch (TAC). Fishery management often fails because TACs are set too high and do not sufficiently restrict fisheries. The question we address in this paper is why do decision makers choose inefficiently high TACs? Our approach is to model...
The introduction of individual fishing quotas (IFQs) in the Gulf of Mexico red snapper fishery significantly impacted the way the commercial fleet operated. As result of the added flexibility afforded by the IFQ program, vessels began taking fewer but longer trips. They also began diversifying the composition of their catch....
This paper illustrates a case study to identify problems and actions to build the basis for an integrated fishery management plan, considering stakeholders participation. The application was made on the southern complex multispecies groundfish fishery, where operate various scales of production under a right-based fishing system. A multimethological approach (Mingers,...
In developing countries the framework for institutional engagement in small-scale fishing communities needs to consider the regional, social, economic and environmental complexities of informal resource-based economies. The combination of socio-economic trajectory of artisanal fisherfolks, their relationship with the environment, the economic pressures and the public policy framework, which often regarded...

The clam, Galatea paradoxa has for decades been an important source of protein to the riparian communities of the lower Volta River and provides employment to about 2000 people, especially women. The fishing grounds have dwindled from 100 km from the pre-dam era to a narrow stretch of 10 km...
The potential economic impact of a fully developed mariculture industry in Alaska is not well understood by industry or policy makers. It is also not entirely clear what is needed to move from Alaska’s current micro industry (approximately $500,000 in annual sales) to a fully developed industry. In general, the...
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....
