Throughout the Indo-Pacific region, communities are increasingly
empowered with the ability and responsibility of working with national
governments to make decisions about their marine resources. In some
instances, co-management arrangements have been successful at
conserving marine resources by developing locally appropriate rules to
limit overexploitation. These examples have often prompted...
There is an increasing demand for marine space from many different economic sectors in the German coastal and exclusive economic zone: sand and gravel removal, wind farms, fisheries, shipping or oil and gas exploration. Additionally, the Natura 2000 directive requires the declaration of areas for nature con-servation. Opposite to other...
We present the outlines of an integrated economic-ecological framework
designed to help assess the implementation of the ecosystem-based
management (EBM) of fisheries in New England. We develop the
framework by linking a computable general equilibrium (CGE) model of a
coastal economy to a bottom-up model of a marine food web...
Recreational fishermen quickly adjust fishing effort directed at a specific
site to variations in fishing quality. Holding all other quality parameters
constant, the functional relationship between fish abundance and the
resulting recreational fishing effort is denoted an effort response function.
This paper proposes a Cobb-Douglas utility function for the benefits...
The herring stocks in the Northeast Atlantic were nearly fished to
extinction in the 1970s. This collapse is usually attributed to advances in
fishing technology. The impact of productivity shocks depends critically on
how sensitive the fish catch is to the size of the stock. If the catch per unit...
In the northwestern Pacific area, the fish alternation phenomena amongst sardine, anchovy and chub
mackerel have been observed in the cycle of about fifty years. The sardine biomass has been drastically
increased in 1930s and 1980s. Chub mackerel biomass has in 1970s, and anchovy has in 1960s and 1990s.
It...
Fish is the cheapest animal protein source in Nigeria and dry fish, in particular, has the potential to solve the pervasive protein shortage problem owing to its relative affordability compared with fresh fish. Boosting dry fish consumption will entail retail price reduction which is achievable only if the market for...
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...
Since the 1990s, moored Fishing Aggregating Devices (FADs) have had a
sharp success in the Lesser Antilles and beyond, because they make it
possible for small nondecked fishing units to reach, at low costs, offshore
resources which they could do only seasonally or resources normally
accessible by large scale vessels...
While French marine fisheries must cope with increasing difficulties, the concept of
multifunctionality of fisheries (as previously observed in agriculture) is emerging
through a diversification of activities. Indeed, fishers resort to alternatives in order to
sustain their activity by calling on new ways to interact with environment, institutional
players, scientists,...
Traditionally, little attention was paid to the market and how the different levels of the market chain
interact. However, recent price developments and the increase in the retail chains’ market share have
raised awareness on the food supply chain and possible market power situations in Europe. This paper
uses 2004-2009...
The main objective of this paper is to analyze the economics effects that
the Prestige oil spill over (2003) had on the Basque coastal fishing industry
by means of a two-stage stochastic production frontier approach. The first
stage is based on the econometric specification of a parametric production
frontier based...
The present study employs a cointegration method and error correction model to analyze the long-run relationship and short-run adjustment of aggregated seafood import demand function for selected Caribbean countries. The results show that there exists a long-term equilibrium relationship between Caribbean seafood import and related factors. Import demand elasticity is...
The cumulative global loss of economic potential from fisheries over the
last 30 years is US $3 trillion. More than half of these fishery sector losses
come from developing countries. However, these are only primary costs
and do not take into account human security risks associated with poorly
governed fisheries....
Aquaculture investments in virgin situations are subject to a large number
of variables and range in values. This is even more so when considering
investments in open ocean aquaculture.
The paper presents the key factors and results obtained for a proposed
large-scale open ocean aquaculture development in Western Australia with...
Interest in ecosystem-based management or the ecosystem-based approach
to fisheries management has rapidly increased on a global basis. Most
options for ecosystem-based management have emphasized some type of
biological and natural conservation or non-use, and minimal attention has
been given to assessing the social and economic ramifications of
ecosystem-based management....
The recovery of fish stocks is in principle an investment decision weighing up short term losses against
future gains. In the Common Fisheries Policy (CFP) of the EU long term management or recovery plans
are a main instrument. One of the basic aims is to move from a short term...
Substitution and elasticity give about the history of supply and the demand structure for fish and seafood. It is also relevant to the detection of change in a particular exploited marine ecosystem. The purpose of this paper is to test if market elasticity of substitution of seafood categories can further...
A guide for 4-H food preservation club leaders that includes tips on organizing content for club meetings, teaching techniques, food preservation experiments and standards for evaluating preserved food products, and a short history of food preservation.
