Alaska is the world’s principal supplier of Sablefish Anoplopoma fimbria a buttery-flavored whitefish greatly prized in Japan. Sablefish are distributed from Baja California to western Japan but the majority of commercial catches are from the Gulf of Alaska and the Aleutian Islands off Alaska. Landings volume and value of this...
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 perception of catfish farmers on climate change and it effect on the contribution of
catfish production to household income in Lagos State, Nigeria were investigated using primary
and secondary data as well as structured questionnaire. A multistage random sampling technique
was used to select 250 African catfish farmers. Descriptive...
The assessment of data-limited fish stocks is crucial for the sustainable management of marine living resources. Dependent on the scope and type of available data, a range of assessment methods are available, such as catch-only, length-based, or catch and survey-based methods. However, these methods suffer from several shortcomings, such as...
Over 11 % of total population engaged in fisheries and aquaculture and out of them about 10% is women in Bangladesh (DOF, 2013). Thus, women make essential contributions to local food security and in many cases; they take part in the commercially fishing production and trading too. There are pervasive...
Cisplatin (CDDP) is a highly active platinum-containing chemotherapeutic agent for use against solid tumors, including ovarian. However, like most antitumor agents, CDDP use is accompanied by non-tumor tissue toxicities leading to unwanted side effects, including neuropathy. To date, the mechanism(s) for these side effects are undefined. However, the clinical features...
Illegal, Unreported and Unregulated (IUU) fishing is a pervasive practice in small scale fisheries. It affects the ecosystem and the livelihoods of people depended on the fisheries resources. Many times management technical measures from development partners and government have been implemented without success. In this study, we apply governability framework...
Worldwide there is a recognition that fishing communities face challenges in changing environments, changing markets, and under different types of stressors. In this context, it is important to identify the causal factors of vulnerability and to understand how people deal with them, in order to find ways to reduce the...
Both internal and external factors influence on the market orientation of actors in the chain. In the case of the Norwegian king crab fishery the regulation of the fishery, i.e. the start of the quota year in September, was regarded by the onshore processing industry to negatively affect their market...
This presentation provides an overview of a presentation held during the Industry and Policy Day held at the IIFET 2016 Scotland conference in July 2016. The presentation was part of Session B3: Adapt, Improvise and Overcome - fishermen's responses to the LO. The session was chaired by Dr. Erik Lindebo...
Adequate energy stores are essential for animal survival, and sophisticated neuroendocrine mechanisms evolved to stimulate foraging in response to nutrient deprivation. Food search behavior is usually investigated in young animals, and it is not known how aging alters this behavior. To address this question in Drosophila, we compared the ability...
Pantar Island's coastal communities like many other coastal communities in eastern Indonesia have a high dependency on marine resources for income, food security and other benefits. Fish products (comprising several species of demersal and pelagic species) are particularly valuable (in addition to other products harvested and traded for export markets)...
There are many drivers for the pursuit of renewable energy extraction from coastal seas. In the United Kingdom these include moving away from fossil fuels to mitigate the impacts of climate change, improving energy security by diversifying supply options, increasing wealth generation in outlying coastal communities, and seeking alternative sources...
Situation: UK scallop fishing is input measures, with effort limits applied to >15m vessels only. There are no output limits. Industry members noted a decline in profits, and suggested that the effort regime was to blame. Government asked for evidence to support the claim and asked Seafish for economic analysis...
Self-management has been recognized as important in successfully governing the common pool resources. This is no exception in fishery. Fishery cooperatives, where fishermen collectively manage the fishery, are garnering much attention from both regulators and academics. In this study, we aim to empirically disentangle the efficiency mechanism of pooling system....
The Pacific sardine fishery is shared but independently managed by three nations: Canada, USA and Mexico. As a result, potential conflict scenarios may arise. A stochastic optimal control methodology is presented to analyze potential conflict scenarios by first considering a deterministic logistic stock growth function and adding a stochastic term,...
Parasites and diseases represent major challenges in aquaculture. In the Norwegian salmon farming industry, costs associated with treatment of sea lice are surging and reached 5bn NOK or 10% of the industry’s total export value in 2015. In addition to the direct impact on production, sea lice affect the industry...
In an open fishery, the competition for the limited fish stock can lead fishermen to a ``race for fish" with sub-optimally high capital investments. Buyback programs to reduce excess capacity in national fisheries have been often used, but seldom successful. Where they have successfully reduced excess capacity, the programs have...
Fishing is the most dangerous job in the United States. When fisheries management creates the incentive to "race for fish", a fishing season can be reduced to only a few days and involve around-the-clock fishing in life-threatening weather conditions. Overloaded vessels, ignoring maintenance problems on vessels, and fishing in dangerous...
During mitosis, sister chromatids are separated by the action of the mitotic spindle. The mitotic spindle attaches to chromosomes at centromeres through a protein complex called the kinetochore. While ~100 proteins have been identified at kinetochores and centromeres, the function of most is poorly understood.
The centromere protein, CENP-T (Centromere...
The Columbia River Treaty has been in effect for over 45 years, but its future is uncertain. Starting in 2014, Canada and the United States will have the opportunity to announce ten years’ notice for termination of the current arrangement. As this artificial deadline approaches, stakeholders are working to determine...
Choosing a policy instrument is a strategic choice. In the case of fisheries interactions with marine mammals and sea turtles, the preferred policy instrument has been a command-and-control approach such as effort reductions (e.g. area closures) and/or technology standards (e.g. gear modifications), even though market based approaches are available. Since...
The Florida reef ecosystem is a highly valuable resource managed by multiple federal and state agencies with many stakeholders. Over half of the $75 million annual dockside value of finfish landings in Florida is comprised of snappers and groupers, but this resource is threatened by overfishing. Current management strategies include...
Dominant models of harvester behavior typically focus on where or when harvesters allocate their effort within a fishery, adjusting effort on the intensive margin in response to fishing conditions and management. However, many harvesters participate in multiple fisheries during a year, and thus a major consequence of management change is...
Background: Fish are an important part of a well-balanced diet as it contains high quality proteins, as well as polyunsaturated fatty acids that are known to play an important role in human health. Consumption of fish, however, is the primary route of exposure to methylmercury in humans. A quantitative risk-benefit...
In many small-scale fisheries around the world, hookah diving is the main fishing method and gear to catch high-value species like sea urchin, sea cucumber, queen conch and spiny lobster. Decompression sickness (DCS) and carbon monoxide poisoning (COP) are diseases related to hookah diving and are the cause of non-fatal and...
Pelagic fish stocks are subject to fluctuations that are driven by climate change, overfishing and changes in market conditions. The fluctuating nature of pelagic fisheries creates uncertainties in fishers’ income, thereby adversely affecting their livelihoods. The aim of this contribution is to reduce the risk and vulnerability fishers face by...
Production data from the red grouper fishery, Mexico, were analyzed to determine the production function. Three different models were tested in cross-sectional data from the period 1988 to 2014. The data were collected from the logbooks provided by skippers. Number of fishermen (crew) per trip varied from 3 to 15,...
Australian governments spend millions of dollars each year on pre-border, border and post-border biosecurity programs. The majority of these programs are resourced through existing deeds of agreement, but some currently fall outside of these funding frameworks. Frameworks not based on economic principles have the potential to deliver sub-optimal outcomes with...
National Standard 1 states that a primary function of fisheries management in the single stock case is the determination of the annual allowable harvest, and it is based on the selection of a target stock size and a control rule that will specify a harvest path that that will cause...
Abstract
Understanding the effects of climate change on forest ecosystems requires exploration of the relationships of different components of the system, such as the response of biota to local hydrology, temperature, precipitation, and elevation. The Long-term Ecological Research Program at the H. J. Andrews Experimental Forest, located in the Western...
Modifications of histone tail amino acid residues are necessary for many reactions involving chromatin. These processes can produce transcriptionally active, euchromatic, or inactive, heterochromatic, segments of DNA. The formation and maintenance of facultative heterochromatin is critical for the proper growth and development of many eukaryotes. Euchromatin can be changed into...
River flooding is a recurrent threat and its control and management continues to be a challenge. It has been recognized that effective flooding control requires a real-time strategy that combines optimization with a physically-based simulation model. Current real-time frameworks that combine simulation and optimization have two main drawbacks. The first...
We developed an integration-based line detection algorithm. Existing line detection methods such as the Hough Transformation (HT) and its variants are insensitive to image noise. The reason is that HT finds lines by calculating the gradient of the image and assumes that the region where the gradient is the steepest...
This paper is the result of a project that began with NAAFE 2015 special session on Fisheries Certification, which asked what forces are driving the market for sustainable seafood. Many previous studies looked at consumers' demand, but in this paper we looked at the entire supply chain (from producers to...
The growth of a plant’s root system is essential for its survival. Preliminary observations suggest that a protein complex called the exocyst may play a role in the development of the root system by facilitating the growth of roots and root hairs. Previous work discovered a protein that potentially interacts...
Proceedings of the Eighteenth Biennial Conference of the International Institute of Fisheries Economics and Trade, held July 11-15, 2016 at Aberdeen Exhibition and Conference Center (AECC), Aberdeen, Scotland, UK.
A quarter of biomass losses in Scottish marine Atlantic salmon aquaculture are attributable to infectious disease. Interventions to reduce the consequences of disease include the use of disease-resistant stock, vaccines and other authorised medicines, functional feeds, and modified farm management strategies. There are, however, only a few evaluations of the...
This paper addresses adverse incentives built into the process of TAC setting as an instrument to prevent overfishing in multispecies fisheries. Under the Magnuson Stevens Act (MSA), the primary law governing marine fisheries management in U.S. federal waters, regional Fishery Management Councils must develop a rebuilding plan for every overfished...
Conflicts over the use of coastal areas are expected to increase in Norway in the future. In Northern Norway, salmon aquaculture and marine fishing tourism are expected to expand, affecting both the space available for other uses and ecosystems, including traditionally harvested fish stocks. While data is available to managers...
As fisheries management becomes more collaborative by seeking input and involvement from stakeholders, it is important to understand and address the diversity of those stakeholders. Gulf Coast fisheries communities include diverse racial and ethnic groups, particularly a large number of Vietnamese Americans involved in all aspects of the seafood industry....
The recent history of fisheries management in New England has seen substantial interannual variability in total allowable catches (TACs), with stocks deemed healthy in one year retroactively identified as overfished soon thereafter. Concurrently, avenues for and examples of coordination between fishermen are increasing in the region, as exemplified by the...
Two faculty-librarians in the US led a small group of undergraduate students from Oregon State University on a short-term study abroad to Barcelona in the summer of 2016. While in Barcelona the librarians and one of their students delivered a presentation to librarians in Catalonia. The paper presentation detailed the...
Western Australian (WA) fisheries have a long association with environmental certification- the WA rock lobster fishery (in 2000) was the first fishery certified under the Marine Stewardship Council (MSC) standards.In 2012 the Western Australia Minister of Fisheries announced that the State Government had committed $14.6 million across a four-year period...
The inter-relationships of vegetation, soils, and stream channel erosion characteristics were examined in two riparian meadows of the Ochoco National Forest where progressive stream headcut incision is a critical resource management issue and restoration priority. Scientific literature establishes that headcut incision leads to lower groundwater tables, with corresponding shifts in...
The Joint Water Commission (JWC) in Forest Grove, Oregon completed a greenhouse gas (GHG) inventory of all the direct and indirect emissions associated with the daily operations of its 75 MGD conventional water treatment plant. Currently, very few water and wastewater facilities have completed a greenhouse gas inventory to date....
This research examines the gendered livelihood implications of fisheries management decisions through an exploration of a seasonal ban on fishing. The 45 day closed fishing season on the Eastern coast of India began in 2001 and applies to mechanized boats. While there is existing research on the impact of the...
Granting catch shares to cooperatives is a fisheries management option that has been widely applied. Although fishery cooperatives systems around the world are structured in various ways, it appears that most share the characteristic that members of the same cooperative are jointly and severally liable for not exceeding collectively assigned...
