The potential economic impact of a fully developed mariculture industry in Alaska is not well understood by industry or policy makers. It is also not entirely clear what is needed to move from Alaska’s current micro industry (approximately $500,000 in annual sales) to a fully developed industry. In general, the...
The fisheries resource is almost and/ or had have been over-exploited in Java Island. Cilacap lies in the southern part of Java has a reasonable stock at this moment but adversed by the climate change. Many parties have not prepared to react for the adaptation with such uncertain situation. The...
Scientific database has proven that Vietnam is one of the most affected countries due to climate change impacts on aquaculture and economies of rural communities. Ben Tre region has suffered immensely from recent salt water intrusion. Climate change generates sea level rise, increase in temperature and salt water intrusion. In...
Climate and marine ecosystem research informs us that marine fish resources would come under increasing stress over the course of the 21st century as global climate change, ocean acidification and de-oxygenation combine with other stresses on the ocean, including heavy fishing pressure and marine pollution, to change the primary productivity...
It can not be denied that climate change is now an overriding environmental issue challenging humanity. Scientific research has proven that Vietnam’s 10 most vulnerable provinces are among the top 25% most susceptible regions in South East Asia. Eight of those ten provinces including Ben Tre province belong to the...

Vietnam has been ranked as one of the countries in Asia with the highest vulnerabilities to climate change impacts on fisheries and aquaculture. Eight of those ten provinces are located in the Mekong River Delta, including Ben Tre Province. We conducted a study to identify the impacts of climate change...
Pacific sardine (Sardinops sagax) in the California Current Ecosystem (CCE) has exhibited extreme sensitivity in its abundance and distribution in the face of decadal-scale climate regime changes. Warm regimes enhance the abundance of Pacific sardine and expand its distribution. Cold regimes lessen the abundance and restrict the distribution. For instance,...

Climate change is generally agreed to be one of the biggest challenges facing the world today, and Australia is no exception. Marine fisheries productivity and distribution is predicted to change with ocean warming. Here, I will examine the economic consequences of climate change on the Australian fishing industry. I will...
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...
Fishing involves the act of hunting for fish by hooking or trapping and may also include pursuing other aquatic animals by extension. However, modern fishing is both a recreational and professional sport in communities with natural and man-made water bodies. Recreational fishing involves fishing for pleasure or recreation and it...
Traditional extensive coastal and semi-intensive aquaculture systems in Southern Europe are facing difficulties, especially due to increased competition for coastal areas uses and market competition, due to low-price products from intensive aquaculture. The positive effects of extensive and semi-intensive aquaculture in coastal areas - including environmental protection and restoration in...
Increasingly fishery managers are expected to take an ecosystem approach to fisheries management that accounts for the interrelationships of target species as well as non-target species and habitat. Fishery managers would benefit from coupled ecological-economic models that includes both the human and ecological aspects of the fishery and incorporates them...
Age and size at maturity are key life-history traits in a fish stock. At the individual level, age and size at maturity affect fecundity, growth and survival. At the population level these factors interact to affect the age and size distribution, the population dynamics and the productivity of the stock....
Our paper aims to study the image of the European fisheries sector, as perceived by European citizens. To
our knowledge, no approach has focused on the perceived impact of fishing on the halieutic resources. More precisely, we seek to analyze the perceived impact on the marine environment of fishing activities...
In industries that are characterized by frequent innovations and high productivity growth, substantial variation in both produced quantity and input use may occur and lead to increased cost. As both excessive input use and misallocation of inputs are costly for the producer, firm-specific measures of both technical and allocative inefficiency...
After decades of decline, real salmon prices paid to California fishermen have rebounded in the past few years. This recent price recovery is probably due in part to reduced availability of fresh salmon in local
markets, but anecdotal evidence suggests increased product differentiation by consumers is also an important part...
When attempting to mitigate the environmental impacts of a fishery there are typically multiple criteria
against which the performance of any measures can be assessed. If the gains are non-commercial (i.e.
non-market) in nature, formally determining how well measures perform becomes more difficult. This study applies the analytic hierarchy process...
The impacts of fishery management actions on shore-based fishing and fishing related infrastructure have received increased attention in the Northeast region of the United States. However, analyses of these impacts have generally focused on directly affected fisheries, ignoring changes in other fisheries and on other sea and land-based activities. Developing...
Over the last four decades, the aquaculture sector especially in developing countries has experienced dramatic growth. The increase in aquaculture production is a combination of area expansion and technological change (enhanced strains, input of feed and fertilizer, and improved management). One example of such technological change is the selective breeding...
In many situation, fishing activity adversely impacts the state of the marine ecosystem, impacts which feed back to affect fish stocks. Some ecosystems appear to have multiple equilibria and exhibit hysteresis, whereby they can become stuck in low productivity states. We show how adding ecosystem dynamics to a classic fisheries...
The sinking of the oil tanker the Prestige in November 2002 off the coast of Galicia in Spain had an
important social, environmental and economic impact. The aim of this paper is to carry out an initial
analysis of the costs relating to a halt in the activity of an...
Despite several factors favoring the development of haddock (Melanogrammus aeglefinus) aquaculture, there is virtually no economic information on its feasibility. This paper uses bioeconomic simulation techniques to conduct an ex-ante impact assessment of the early life stages in haddock production. Using an economic engineering methodology, early life stages are modeled...
In 1998, the National Marine Fisheries Service (NMFS) launched a series of marine recreational angler expenditure survey in the Northeast (NE) management region (Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Delaware, Maryland, and Virginia). This series was extended to the Southeast (SE) management region (North Carolina,...
Cette communication s'intéresse à l'essor que connaît l'aquaculture en Thaïlande depuis quelques années dans le but de mettre en évidence certaines répercussions socio-économiques provoquées par le développement accéléré de cette activité. L'auteur présente le cas d'un village côtier du sud-est thaïlandais où la transformation récente d'un territoire rizicole en une...
En quelques années, l'Indonésie est devenue un des premiers pays producteurs de crevettes. L'extension et l'intensification rapide des élevages a des répercussions socio-économiques et écologiques majeures. Après un pic de 130.000 tonnes en 1992, la production est tombée à 100 000 tonnes en 1993. Depuis, le développement de nouveaux sites...
The global aquaculture industry has seen dramatic growth over the last two decades, and is forecast to become increasingly important into the next century. The aquaculture output, of the African continent, however, remains low at about 4% of the total. There is a perception of failure where donor assisted projects...
