A scientific knowledge gap exists with regard to how benthic habitat is affected by destructive fishing methods, such as bottom trawling, and how this impacts upon the productivity of commercial fish stocks. This
article addresses analytically the effects of destructive fishing practices of a single gear fishery on a non-renewable...
The Northern Prawn Fishery is one of the most valuable fisheries in Australia with a yearly estimated value of production of about $64mil. Nine prawn species are commercially harvested from the Northern Prawn Fishery with 80% of annual average catch represented by the banana prawn (Fenneropenaeus merguiensis) and the tiger...
This paper investigates the application of cellular automata (CA) models in bioeconomic studies involving varying biological growth and area distribution. A simple 2D continuous cellular automata (CCA) model is presented and incorporated in a fish harvest model based on standard assumptions of economic rational behaviour by individual decision makers. The...
The individual size of fish as a proxy for life-history traits and market
value displays an important, yet in bioeconomic modelling often ignored
biological and economic parameter. This raises the question if and to what
extent the consideration of a pricing related to the individual size
influences optimal harvest strategies....
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,...
Adoption of aquaculture, particularly among the rural poor, requires timely
and quality seed at the farmer level. In areas of Northwest Bangladesh, the
region considered most marginalised for food production, carp polyculture
has been improved through the introduction of Nile tilapia, but constrained
by under-developed seed supply. In order to...
This paper addresses to a comparative approach of long term changes in the characteristics of marine fisheries at a regional scale, in three ecosystems: up-welling, tropical and temperate. The South Moroccan
continental shelf, under the influence of the Canary current, where up-wellings take place, is the most productive part of...
The purpose of this paper is to provide a comparative index characterization of shrimp farms in Bangladesh, India and Indonesia. There has been considerable work carried out on shrimp farming in South East Asia with emphasis on biology, environmental factors, management and trade issues but much less work on the...
Research of value chains in fish industries indicates that there is great
difference in value creation of the domestic part of the value chain between
countries with underdeveloped fish industries and developed fish
industries. This comparison is founded on the authors´ research on the
value chains of Icelandic cod and...
The productivity and resilience of fisheries are subject to a multitude of dynamic and interrelated influences that arise from complex coupling of fish populations with the natural and human systems of which they are a part. With few exceptions, fisheries are managed independently, ignoring important natural and human linkages among...
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...

Millions of people across the world, and particularly in Asia, depend on small-scale fisheries for a livelihood. Small-scale fisheries contribute in significant ways to employment, income and food security, and in many parts of the world small-scale fisheries constitute the backbone of remote, rural economies. However, several problems, within and...
The primary purpose of this Guide is to encourage private landowners to conserve, and when appropriate, actively manage Oregon white oaks that already exist on their property, and consider planting additional oaks. In the early chapters of the Guide, we describe some of the uses and benefits of this remarkable...
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...
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...
This paper develops a count data model of target species and bycatch
production for an arbitrary number of species that handles correlation
between species and over time. The model is applied to a large observer
dataset for fishing trips taken from 1990 to 2008 for roughly 150 vessels
participating in...
Five species of marine turtles are found within the territorial waters of Vietnam, and all populations are declining. As part of a broader strategy and Action Plan, the Government of Vietnam and WWF Vietnam have launched a two-year project to: 1) document relative gear impacts, and geographic hotspots , for...
After three-quarters of a century of introduction of 152 conifer and broadleaf species,
no promising candidate exotic was found for the Douglas-fir region. Growth curves
spanning 50 years or longer are figured for many species. Firs, pines, larches, spruces,
hemlocks, and cedars originating in northwestern North America had superior growth...
An industry group has proposed a novel mechanism for management of the multispecies groundfish fishery off the northeastern United States. Under this mechanism, individual harvesters would be allocated a budget of points, to be expended landing fish. A regulatory body will set different prices, denominated in points, for landing each...
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....
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...
In 1996, the US New England Fishery Management Council formed a
technical team (PDT) to develop a new plan for Atlantic Herring (Clupea
harengus harengus). The inshore stock was close to fully exploited while
the offshore stock was underexploited. There were few full-time herring
harvesters and very few processors. Fresh...
Indian Ocean Tuna fisheries after a rapid development period from
seventies to the end of the last century are faced with challenges including:
the fishing capacity control, the profitability improvement, and the
limitation of impacts on high seas biodiversity. In this area, tuna species
are exploited by coastal states as...

Marine scientists and stakeholders are increasingly advocating ecosystembased
fishery management (EBFM). However, the way to operationalize
such EBFM remains controversial. The viability approach can be a relevant
modelling framework for EBFM as it accounts for dynamic complexities,
uncertainties, risks and sustainability objectives balancing ecological,
economic and social dimensions together with...
An investigation was carried out on Lake Geriyo in the month of April to know the pattern of
fish exploitation. The fish species sampled were mainly by using canoes as they were landed at
the landing site of the lake. A total of fourteen (14) species of thirteen (13) families...
This study is part of the research program on theme Post Harvest Management Strategy of Supply Chain For Thai Shrimp Products currently supported by the Department of Fisheries (DOF) and Post Harvest Technology Institution (PHT), Chiangmai University (CMU). That focuses on the cost efficiencies of 51 shrimp processing plants under...
This interview took place on the back porch of her house. It was laid back and she gave me coffee to drink. She was also more interested in asking me questions about who I am than actually getting interviewed. She told me that she wanted to hear what I had...
