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...
