Australia’s western rock lobster fishery is its most valuable and hence from a biological perspective most tightly managed major commercial fishery, yet it has been beset by problems of miniscule recruitment over the past 3 years. This coming year 2010-11 is little better. It was the joint first Marine Stewardship...
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...
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...
Thomas More’s text, Utopia, introduces the word “utopia” in conjunction with an ideal society, prodding readers to think of “utopia” as synonymous with “ideal.” Indeed, Utopia is structured as an egalitarian and communal place, rendering it highly ideal to those wishing for equality in their own worlds. However, More overturns...
Understanding the complexities of ecosystems is difficult enough, but when the human dimension is added to the inherent uncertainty and risk in fisheries management, the actual versus expected results move from the counter-intuitive to the paradoxical. Without an adequate understanding of the interrelationships between ecosystem components, including the human dimension,...
The present study uses normalized profit function and adaptive expectation approaches to analyze U.S. catfish farm supply. Empirical estimations give short-run supply elasticity of 0.25 and 0.26 and long-run supply elasticity of 0.47 and 2.1 in each of the two approaches, respectively. Technological improvement is attributed for only 9.8% out...
Over the past century, the tuna canning industry has been dominated by a few big companies, some of
them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA,
Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...
Considerable attention has been applied to the development of models explaining how fish stocks change over space
and time, from relatively simple stock-recruitment relationships to ecosystem models with a complex food web
structure. However, in many case studies fishing effort is assumed to be exogenous and even in dynamic models...
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 University of British Columbia based Global Ocean Economics Project will, in its second phase, be
addressing the issue of the rebuilding of hitherto overexploited capture fisheries. In so doing, it looks
forward to working closely with the OECD. The paper argues that the first step in this second phase...
The fishing industry is particularly important for Sri Lankans for the domestic supply but there is also a
small but growing export market for high value products. The potential for economic development lies
there with yellowfin tuna as the most important specie. In this research the efficiency and productivity of...
This paper deals with the sustainable management of a renewable resource
based on individual and transferable quotas (ITQs) when agents differ in terms of
harvesting costs or catchability. In a dynamic bio-economic model, we determine
the conditions under which the manager of an ITQ system can achieve sustainability
objectives which...
In developed – and some less-developed – societies, managing an “open access,” renewable
natural resource sector generally involves taxes, quotas, or other government or community
restrictions. But some cultures, especially in their early years, have taken a different approach,
one that involves transfer of part of the output of the...
Fresh fish trade in Kribi, Cameroon is characterized by high uncertainty in a context of specific assets. Facing this uncertainty, actors have developed hybrid coordination mechanisms centered on contractual arrangements and networks. These implicit contractual arrangements involve price negotiation, delivery agreements between fishermen and buyers, as well as transactions including...
The two main pillars of the Icelandic fishing industry are the large vertically integrated fishing companies and the SMEs, specialised in fishing, producing or marketing. In order to understand how they are able to function side by side and at the same time secure a relatively high value added for...
In discussing property rights, efficiency and fisheries management economic literature often refers to a fishery with a hypothetical single owner, comparing it to fisheries with more fragmented ownership. Through a range of effort reductions, since the near collapse of the fishery in the early 1980s, the Exmouth Gulf Prawn fishery...
Overcapacity is probably the most fundamental challenge to fisheries management as it can lead to both overfishing and to low profitability. Most of the Norwegian fisheries have limited entry, through the use of annual permits (coastal fleet) and licences (ocean going fleet) in combination with individual vessel quotas (IVQ). Limited...
Shellfish farmers make their production decisions in an environment characterized by multiple
uncertainty. As shellfish farming is done in an open area, producers face a large number of risks:
e.g. biological, environmental, pollution or climatic risks. Historically, this sector has been
affected by several crisis; the last ones were the...
The north coast of Java Sea is home to thousands of small-scale fishers fishing for small pelagic fish. The
small pelagic fisheries have been the main economic and social activities for coastal communities where
other alternatives are limited. The fisheries have been experiencing turbulent states during the last thirty
years...
