We introduce a modified version of the standard Gordon-Schaefer fishery model. Standard theoretical models usually treat fishing effort as an aggregate measure encompassing all different types of inputs. Consequently, these models do not enable us to examine the problem of fleet redundancy and capital stuffing separately, i.e. two ways in...
Recently the greening of fisheries has become a central theme among policymakers. The discussion on
how improved governance structures and policies can
help in achieving green growth goals is yet in its
infancy. One problem is that there is a lack of a general framework in which to address those...
Research costs are constantly rising world-wide, research institutes are often bound to conduct research in bad weather conditions. Fish density accurate estimation made via acoustic echo integration is problematic in bad weather conditions due to acoustic signal attenuation by waterborne air bubbles and vessel movement, which result in an underestimation...
The contributions of small-scale fisheries to income and employment are well recognized but not sufficiently understood. It is difficult to gauge, for instance, whether this sector is economically viable, especially in the context of large-scale economic, social, political, and ecological change processes. These knowledge deficits create an environment of uncertainty...
Culture of resilient species to drought and stressed water quality conditions may be a significant part of the future of African aquaculture. Air breathing fishes potentially have a role in low-management culture systems because dissolved oxygen is not a limiting factor. The African lungfish (Protopterus spp) is advantageous because it...
The Icelandic fisheries management system has always been controversial in Iceland. In the wake of the force of the financial crisis that hit Iceland the political debate has become increasingly emotional and heated. In this debate a rational understanding of the fisheries management system‚ aims and efficiency has lacked. Previous...

In the Pacific Ocean, the total catch of skipjack tuna has been increasing rapidly. Then, eight of Polynesian, Melanesian, and Micronesian countries (PNA countries) have concluded a cooperative management of tuna fisheries. Although those countries do not catch a large amount by themselves, the main migrating area is included in...
In Zanzibar, an increasing number of women have entered fish markets acting as a link between fishers and
consumers, i.e. a middleman. However, since fisheries are traditionally male dominated, women receive little
recognition. Thus, gender analysis in the fisheries sector potentially can enhance management and development
policies as well as...
Socio-economic impacts of the tsunami and the nuclear power plant accident are discussed in this study. A strong earthquake hit Japan on March 11, 2011. It triggered massive tsunamis and as a consequence, 28,612 fishing boats (equivalent to 15.4% of the Japanese fishing boats) were lost or destroyed and 319...
Small-scale fisheries are no exceptions to the requirements of staying within the biological bounds of sustainability, by purposively limiting fish harvests, and of maintaining productivity of oceans and freshwater systems, by protecting ecosystem health and habitat quality. However, while these fisheries, like all others, have the potential to pose conservation...

As many cases of tropical small-scale fisheries, the French Guiana coastal fishery is characterized by
the
high fish biodiversity of its ecosystem, the weak selectivity of the fleets exploiting the resources,
the
heterogeneity of the vessels in term of size and fishing techniques. The traditional tools used to manage
fisheries...
The estuaries and coastal waters of Northern Samar are characterized by an abundance of mud crab juveniles (Scylla serrata). These, however, are being overexploited by mud crab collectors with backing from financiers in other islands to the disadvantage of coastal poor producers. The SEAFDEC/AQD technology transfer of mud crab nursery...
The efficiency analysis literature has long acknowledged the difference between program/policy effects and relative efficiency effects. The use of incentive compatible policy has been an important research agenda for fisheries economists, and Canada uses an array of policies and regulatory tools to fulfill the objectives of their Fisheries Act. One...
In 2010, the New England Groundfish fishery adopted a sector-based management plan, wherein self-identifying groups of harvesters are allocated their collective total share of the harvest of each species as a group right, that they may manage in any way they wish. This means a single fishery with a single...
In Europe, the United Kingdom is one of the top nine producers of trout. Scotland accounts for

Over 90% of global aquaculture production comes fro
m the Asia Pacific region. International trade in live
aquatic animals and the intensification of aquaculture practices over the past several years have led
to
emergence and spread of several aquatic animal diseases in the region. At the same time, while the...
With the development of the ecosystem approach to f
isheries (EAF), fisheries management is
increasingly required to deal with multiple, often
conflicting objectives. In this context, the
stochastic co-viability approach has been proposed
as a useful modeling framework as it allows
for the combined representation of complex fisherie
s dynamics,...
The objectives pursued by governments managing fisheries may include harvesting the fish stocks to maximize profits, to minimize the impact of harvesting on the marine ecosystem, or to secure jobs in the fishing industry. These objectives all depend on the composition of the fishing fleet as the various vessel types...
Production quotas can restore efficiency in industries characterized by production externalities, such as resource industries and industries with environmental regulations. However, with imperfect quota enforcement, firms may have incentives to build up excess capacity relative to their quotas. Firms with excess capacity may, in turn, have stronger incentives to violate...
The Atlantic deep sea red crab (Chaceon quinquedens) is the target of a small, directed fishery in the Northeast US, which has been managed using total allowable annual catches (TACs) at the fleet level since 2002. Although not a catch share fishery, it shares many of the same features, behaviors,...
Acknowledging that there is stochasticity in the dynamics of a fish stock, one has a situation where the fish stock can collapse even without any fishing pressure. To derive the probability of collapse, we suggest a Monte Carlo approach because it is relatively simple model and can capture complex stock...
The depletion of important fish stocks and the degradation of marine ecosystems are common problems worldwide. Two approaches that have been widely used to restore depleted fish stocks are the implementation of harvest control rules and the establishment of marine reserve networks. Harvest control rules, underpinned by the monitoring and...
A theoretical model links price risks at processors market to farm supply response. Price risks at wholesale market affect processors‚ factor demand for farm-raised catfish. The fluctuation in factor demand also influence the farm-raised catfish supply response. Price risks at wholesale market reduce processors‚ factor demand for farm-raised catfish, and...
In order to ensure sustainable aquaculture development basic elements needs to be taken into consideration, i.e. environmental, social and economic aspects. Most of the research focuses on the environmental aspects and very little of the social and economic aspects. There is no doubt that when dealing with sector development, socio-economic...
Biologists have criticized traditional biomass models in fishery economics for being oversimplified.
