Non-market valuation research has produced value estimates for over forty threatened and endangered (T&E) species, including mammals, fish, birds, and crustaceans. Increasingly Stated Preference Choice Experiments (SPCE) are utilized for valuation, as the format offers flexibility for policy analysis and may reduce certain types of response biases as compared to...
Incorporating catch or harvest rate information in repeated-choice recreation fishing demand models is challenging, since multiple sources of information may be available and detail on how harvest rates change within a season is often lacking. This paper develops a framework for evaluating which source(s) of information should be used to...
During AY 2009/10 OSU Libraries’ Research and Innovative Services Department (RIS) conducted a pilot project on “environmental scanning.” One of our goals for the year is to develop a process to investigate emerging trends based on a topic and disseminate our findings. Initially we each scanned a segment of the...
One component of the Bering Sea Integrated Ecosystem Research Project
(BSIERP) is a spatial economic model that predicts changes in fishing
activity in the Bering Sea pollock fishery that may result from climate
change. Models such as the one employed here have been used in the
Bering Sea and elsewhere...
Species within marine ecosystems are known to be interconnected. This is
a result of many factors including predation and competition for resources.
Despite this, many fisheries are still managed using a single species
framework. This paper uses cointegration analysis to quantify the
relationship between different fish species. Cointegration is a...
This study estimates the demand for saltwater recreational angling trips
within the Southern California Commercial Passenger Fishing Vessel
(CPFV) fishery. The CPFV fishery provides a variety of trip types to
support recreational anglers targeting several species including, tuna,
rockfish, yellowtail, and shark. Trips vary by fishing location, by length of...
Many of the coastal counties in Florida have active artificial reef
deployment and monitoring programs. These reef systems have been
shown to be an important destination for the marine recreational boating
industry, as well as for the for-hire commercial sector (i.e., six-pack charter
vessels, guide boats, party/head boats, and dive...
The motivation of this paper is to detail the application of Markov chains in
simulating fleet dynamics in Australia's Northern Prawn Fishery (NPF).
The Markov chains are enhanced through the use of the multinomial logit
(MNL) and Seemingly Unrelated Regressions (SUR) models to explain
transition probabilities. The terms MNL Markov...
The past twenty years has seen the offshore outsourcing of post-harvest
fish processing gain unprecedented momentum. The growth in offshore
processing is a further stage in an increasingly globalised fisheries value
chain. Raw material is head and gutted, then frozen, and transported to
processing sites in Asia (especially China). The...
This paper is based on a review and assessment of lessons from three
projects on fisheries co-management in Bangladesh: i) Community-based
fisheries management (CBFM), ii) Management of aquatic ecosystems
through community husbandry (MACH), and iii) Fourth Fisheries Project
(FFP). These co-management initiatives established 191 Community Based
Organizations (CBOs) in 179...
Due in part to limitations in data and models, fishery managers have been
hindered in their efforts to simultaneously address economic and ecological
effects of management measures. In the US, this promotes violation of
National Standard 8 of the Magnuson Stevens Fishery Conservation and
Management Act, which mandates that conservation...
The paper develops a model of recreational fisher behaviour in which
fishers maximize their individual utility by adjusting fishing time, trips,
catch and size of fish caught. It investigates the optimal behaviour or an
individual fisher with and without constraints such as bag limits. The
model is used to assess...
This study analyzes supply and demand system for the mussels in the EU
markets. The results show that farmed and wild quantity of two main
species of mussels, Mytilus edulis and Mytilus galloprovincialis, have
declined in recent years due to limits of seed and space. However, a
demand system analysis...
Inspired by the export boom developing countries got involved in multiple
export earning activities. However shrimp exports have become quite
lucrative activities for many developing countries including Bangladesh.
Shrimp occupies a good chunk of our export income. In calculating the
return from shrimp exports the usual practice is the nominal...
In the economic literature on fisheries management complete information
is normally assumed. In reality fishermen have more information than the
regulatory authority. In the present paper a principal-agent approach is
applied to analyse management with a tax on fishing days under
asymmetric information about the skill of fishermen (productivity) and...
Many renewable resources, such as fish stocks, water or environmental
quality, are shared between different countries. The management of such
resources then relies on international agreements. We develop a model of a
shared renewable resource for which there is an international agreement
that determines each country's share of total extractions....
The economy of Bangladesh has benefited enormously from the rapid
development of the aquaculture production, in particular from shrimp
cultivation. In 2007-08 Bangladesh earned US$ 445.41 million from
shrimp export, which is about 4.25% of the value of total national export.
There are over 600,000 people employed directly in shrimp...
Pacific sardine (Sardinops sagax), which is a transboundary resource
targeted by Mexican, U.S. and Canadian fisheries, has exhibited extreme
decadal variability in its abundance and geographic distribution
corresponding to water temperature regime shifts within the California
Current Ecosystem. Our study develops a three-agent bioeconomic
framework that incorporates environmental effects on...
A major simplification in bioeconomic models is that the model parameters
and functional forms are assumed known. In fisheries, the failure to capture
model uncertainty can easily cause overconfidence in model outputs and
resultant policy recommendations. Although fisheries modelers regularly
assume rather complete knowledge of the systems they study, in...
Conservation goals and resource use can easily conflict when externalities
exist. This is the case in the Baltic Sea with grey seal (Halichoerus grypus)
and Atlantic salmon (Salmo salar). Both of the species have been defined
as critically endangered in the late 20th century but due to conservation
schemes, harvest...
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...
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....
In 2003, an industry-financed, government-administered buyback of trawl
fishing permits and vessels took place on the US West Coast, resulting in
the retirement of about one-third of the limited-entry trawl fleet. The lack
of cost data in this fishery precludes an analysis of how the buyback has
affected profitability, but...
The paper will report on the development of a new set of wealth-based
Fishery Performance Indicators (FPI) for evaluating and comparing the
worlds fisheries management systems. A wealth-based fishery management
system is one that is ecologically sustainable, socially acceptable, and
generates sustainable resource rents or profits. The Fishery Performance
Indicators...
Assessing distribution of the expected bio-economic impacts of
management measures between fleet segments is a main issue for decision
making in fisheries management. This requires as a first step a good
description of the system and of the interactions between fleets through
stocks. Making this assessment operational also needs flexible...
ITQ introduction has had several effects on fisheries in terms of, for
example, changes in the composition of the fishing fleet and fishing
efficiency gains. After ITQ introduction in the Tasmanian rock lobster
industry in 1998, an increasing number of fishers have become dependent
on quota leasing to catch fish...
Recent work in the domain of fisheries ecology has shown that major
changes occur in fish communities exploited by commercial fisheries.
Selective fishing pressure on the more highly valued components of fish
communities is amongst the key factors proposed to explain these changes.
Under de facto open access conditions, it...
While right-based managements have often been encouraged as effective
management tools, few studies presented an empirical analysis on the
effects of those systems. This paper focuses on a special form of Territorial
Use Rights Fisheries called an income pooling system, and examines the
effects of the system empirically. Income pooling...
Upon request by the European Inland Fisheries Advisory Commission
(EIFAC), group of prominent economists and other social scientist were
assembled to create a set of guidelines for assessing socio-economic
benefits of the European inland recreational fisheries. A wide range of
international interest groups and academics were included in this process...
Fishers from coastal communities have been facing hazards of different
nature. Those stressors plus high fishing pressure have contributed to
resources deterioration, which in turn affects peoples livelihood, creating a
vicious circle. In order to understand this vicious circle and to explore how
this could be turned around, in this...
Aquaculture is one of the most dynamic food-producing subsectors
worldwide. In the Philippines, shrimp monoculture started in the 1980s,
only to collapse less than a decade later due to disease. More recently,
extensive polyculture of fish, shrimp and mud crabs has developed. The
objective of this paper is to analyze...
Environmental resource values are often obtainable only through stated
preference or hypothetical surveys because other nonmarket valuation
methods only account for part of the resource value or are unsuitable.
Despite the recent popularity and many advances in discrete choice
techniques for nonmarket valuation, the implications of questionnaire
structure, namely framing...
This paper investigates the welfare effects of random closures in a fishery
operating under open access. At each point in time, a fishery is facing the
probability of an extreme event that impairs fishing activities but has no
direct impact on the fish population. Examples include massive blooms of
dinoflagellates...
The UN Law of the Sea of 1982 assigned rights and responsibilities to the
fishery resources within 200 nautical miles of the coast (i.e.,the Exclusive
Economic Zones: EEZs) to the adjacent maritime countries. A key
responsibility is the requirement that these countries manage their marine
living resources sustainably through time...
With a national policy on catch shares in progress in the United States and
increasing use of transferable fishing rights in fisheries worldwide, it is
important to understand how the markets created by these programs
function in the real world. This paper presents information collected from
interviews with Florida spiny...
In this paper, we analyze the efficiency of the existing management regime
of the Bay of Biscay anchovy fishery, which has been closed since 2005
due to stock collapse. We also study Pareto improving strategies to
improve management of the fishery once the moratorium is lifted, expected
for spring 2011....
The paper empirically illustrates the social capital status of the tsunami resettlements
and its impact on donor dependency. After five years of Indian
Ocean tsunami, study investigates the resettled fishing communities in
eastern coast of Sri Lanka. Sample composed of 200 fishing families resettled
in new locations but not in...
New Zealands quota management system is based on transferable
harvesting rights operating within regulated allowable harvest limits. The
system has evolved since its implementation in 1986. One particular
challenge has been the design of mechanisms to encourage the balancing of
catch against quota. A model is developed for a target...
Fisheries constitute a major productive sector in Latin America and the Caribbean. This sector generates income, provides employment, and makes a significant contribution to food security and the generation of foreign exchange. With most fishery resources fully exploited or depleted, opportunities for fishery development lie primarily in restoring depleted
stocks...
Artisanal fishermen are the great unknown of fisheries. Being the more
numerous segment, is the more abandoned community by managers. In a
generalized context of overcapacity and taking into account the dwindling
state of resources, the situation seems to be paradoxical since artisanal
métiers are considered to be the less...
Establishing marine protected areas (MPAs) often results in fishers being
displaced from at least some of their existing grounds. A direct
consequence of this is that governments may be required to make
compensatory payments to the firms that are affected. Experience has
demonstrated that these payments can be significant, as...
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...
