Rocks are defined as aggregates or mixtures of minerals; rocks also include noncrystalline materials such as the natural glasses, and organic material such as coal. Rocks are found ready-made in nature. They are not homogeneous nor are they crystalline, although they may be made up of crystalline material. The composition...
The purpose of this study was to determine whether knowledge
beneficial to an organization operating under normal conditions could
be gained by studying a manufacturing plant operating with salaried
personnel during a labor strike. It was hypothesized that no difference
in productivity would exist between the strike work force study...
Dry strength is an inherent structural property of a paper sheet. It is due primarily to the development of fiber-to-fiber bonds. Polyamines, especially polyallylamine·HC1 (PAA), were found to be suitable mordants for rosin sizing. However, their effectiveness as dry strength agents has not been studied. In this study polyallylamine·HC1 was...

Letter from federally-recognized treaty fishing tribes of the Columbia River Basin to Darlene Hooley requesting continued funding for the Fish Passage Center.
At a hearing about the Green Paper (an analysis of the EU fisheries policy over the last 10 years and an outlook for the next decade) the following statement was given by an economist: „The Ecosystem Approach is the fata morgana of the fisheries biologists.“ Indeed, a lot of biologists...
The inclusion of ecosystem considerations in fisheries management implies two changes with extensive institutional repercussions: the uncertainties about states and outcomes rise dramatically and a multiplicity of new stakeholders, interests and objectives must be accommodated in the management institutions. The first change may potentially add immense costs to the management...
Small-scale fisheries play an important role in generating employment, income and livelihood to the
fisherfolk. It constitutes 81 per cent of the total fisheries sector in India. But, this sector remains neglected
and the fisherfolk are socially and economically backward. Even after six decades of planned
development nearly 62 per...
The result of changes in regulation or monitoring and enforcement of commercial fisheries are highly dependent on fishers’ supply response decisions. One central determinant of fishers’ reactions to such changes is their risk preferences. Empirical studies of fishers’ preferences have found that most fishers are risk averse. In this paper,...
The fisheries sub-sector in Nigeria accounts for about 40% of animal protein in the diet and it contributed 4.74% of the agricultural share of the nation's GDP in 2003. Recently, demand for fish products has doubled as other sources of animal protein have become expensive due to pressure by the...
Equations are presented for predicting height to crown base (or bole ratio) for fourteen species of trees common to the mixed-conifer zone of southwest Oregon. Nonlinear regression was used to fit a weighted logistic function for each species. The independent variables include height, crown competition factor in larger trees, stand...
If fisheries management is supposed to affect behaviour, it has to be enforced. Fisheries
enforcement has generally been found to be quite costly compared to the attainable rents from
the fishery. This has a number of important implications. First, obviously, it is economically
important to operate the enforcement activity at...
Indonesia as an archipelagic country with 81,000 Km coastline has the best, wide coastal and marine area in the world. The abundance of resources in coastal and marine area should be a potential capital for the community to improve their livelihood. However, the development activity in the coastal area so...
The study looked at gender roles in the value chain for small scale Tilapia capture and marketing in villages and market centres along the Sinazongwe shore line of Lake Kariba, Zambia. Objectives were to identify dominant gender in supply chain functions, compute price changes due to value addition and isolate...
A bioeconomic model allowing different degrees of harvesting closures for two sub-stocks consisting of mature and immature fish is presented. Hence the model opens for partial closures of fisheries on both sub-stocks. Migration between the two sub-stocks is defined as recruitment of the young to the mature sub-stock, and egg...
A method is introduced and applied to analyse changed in productivity of firms harvesting in a multi-species fishery. The index-number technique decomposes firm profits into its contributions and can be used to assess economic performance by both regulators and individual firms across an industry and over time. Using an unbalanced...
Setting aside the traditional simplistic “tragedy of the commons” notion, fisheries crises observed in the Northern Atlantic may be seen as the result of “mismatches” in the decision making process. The collapse of two fisheries, Atlantic Cod (Gadus morhua) in Canada and European Hake (Merluccius merluccius) in Europe, illustrate the...
Rights-based management in federally managed fisheries off Alaska has evolved rapidly over the past decade. While license limited entry and individual quotas (with rights assignments to vessel owners) were the principle tools under consideration in the early 1990s, in 2002 a wider range of programs and program options are under...
Fisheries worldwide continue to suffer from the negative consequences of open access. In 1986, New Zealand responded by establishing an individual transferable quota (ITQ) system that by 1998 included 33 species and more than 150 markets for fishing quotas. We assess these markets in terms of trends in market activity,...
The language G is an expression based language designed around the concept of the stream; where a stream is a sequence of values, perhaps infinite in length. There are no statements in G, only expressions. All expressions are evaluated on a demand driven basis, no computation takes place that does...
Fisheries management has been carried out on the assumption that a fish population is in equilibrium with the fishing effort under the average environmental conditions and hence there must be a maximum sustainable yield (MSY). However, since the simultaneous rise and fall of the interdecadal and global scale of sardine...
To disseminate update technologies and to enhance capabilities of resource poor farm families for the production of capture as well as culture fisheries, using natural and socio-economic resources an extensive study on linkage between resource availability and production potentiality were undertaken in the study area (under New Alluvial Zone of...
In this paper we use stock size, harvest quantity and fishing effort, respectively, as strategic variables. We model a two agent (nations) non-cooperative fishery game, where the agents harvest a common fish stock. The planning horizon is infinite. The model is solved successively using one instrument at a time as...
Market chain analysis can provide information on distribution of costs and profits to intermediaries and aid in identifying concentrations of market power. There is a paucity of research and limited empirical data on market chains in developing country fisheries, especially small-scale fisheries. With these fisheries dominated by artisanal and subsistence...
With heightened media attention on the poor state of world fish stocks and the environmental impacts of aquaculture production methods, both governments and seafood industries are keen to demonstrate support for improved management measures. This paper includes results from a DFID funded project concerned with seafood certification, ecolabelling and developing...
The increasing demand for shark fins in Asia and the shark s life history pattern of slow growth, late maturity, and
few offspring, have generated concerns regarding the sustainability of shark resources. Despite this concern, little effort has
been spent on understanding the markets for shark fin products and the...
Great efforts have been made in order to manage the fisheries more sustainably, but so far, most of these efforts have failed. This is putting the welfare of current and future generations at risk. The fishing fleets have catching capacity that well exceeds the rate at which ecosystems can produce...

In Senegal, the management of artisanal fisheries which account for approximately 90% of the total catch is an urgent task in view of the declining trend of fisheries resources. In this context, community-based fisheries co-management (CBFCM) has been attracting much attention in recent years as an artisanal fisheries management method....
A discrete-time bioeconomic model of two stocks is presented, where one of these two stocks can be partially protected by a reserve or some other hindrance to harvesting. The interaction between the two stocks is geographic, in the sense that the protected stock can migrate out of the reserve and...
There has been little research into how end-user programming environments can provide explanations that could fill a critical information gap for end-user debuggers - help with debugging strategy. To address this need, we designed and prototyped a video-based approach for explaining debugging strategy, and accompanied it with a text-only approach....
Beginning in 1998 on the East Coast of the United States (US) and ending on the West Coast of the US in 2000, the National Marine Fisheries Service (NMFS) conducted a series of surveys to gauge marine recreational angler expenditures by region. These surveys were conducted using the Marine Recreational...
The optimal management of the European hake fishery (southern stock) is analysed. Since
the activity of the fleets has different impacts on marine resource in this fishery, depending
