Another environmental impact is with the impact on wild salmon. The aquaculture industry argues that farmed salmon eases pressure on wild stocks. Theoretically, this may be true but in practice the argument lacks strength. ild salmon stocks are subject to quotas and active management from the Department of Fisheries, and the global overfishing problem is not necessarily related to wild salmon stocks. There is no evidence presented that demand for wild salmon decreases as the result of the increased availability of farmed salmon.
Most farmed salmon are Atlantic salmon, which are preferred by the industry for a couple of reasons. These salmon are not native to British Columbia. Specimens do escape from fish farms, and this creates significant risk to local species. On the Atlantic Coast, wild stocks of Atlantic salmon are listed as critically endangered, and can be put at risk by escaped farm fish. In British Columbia, the…… [Read More]
Aquaculture in the Midwest
Except for bucolic scenes of fishing on rivers meandering across the Midwest and Great Plains, most people don't equate fish with that region, at least not huge catches of commercial fish. However, as long ago as 1996, "traders in the 'futures pit' of the Minneapolis Grain Exchange were shouting and signaling bids and offers for spring wheat, white wheat, white shrimp and black tiger shrimp" (Weber 1996). Moreover, the shrimp being traded in Minneapolis was of interest to the local trading office of the Thai government (Weber 1996); Thai food depends heavily on shrimp, so finding it at commodity prices is important to the Thai people.
Naturally, this scene would not have been possible except that it is no longer necessary to harvest shrimp from warm coastal waters where they live naturally. Shrimp, as well as other shellfish and finned fish as well, are raised on…… [Read More]
Two of the
greatest threats to sustenance in India are drought and pestilence, both of
which account for the widespread failure of many crops to reach harvest.
The bollworm that ravages cotton crops in India accounted, in 2003, for the
destruction of more than 50% of the nations' cotton harvest. (Yang, 1)
However, during this same year, a breed of cotton was engineered for
resistance against the bollworm "with a gene from the insecticidal
bacterium Bacillus thuringiensis (Bt)." (Yang, 1) The results would be a
dramatic success in yielded greater crop harvest with no reported negative
health outcomes. Naturally, this is still an area which does require far
greater scientific research before we can fully dismiss the possibility of
its negative impact on environment, ecology and human health. But it does
offer some promise to developing nations.

The plan would be the result of the scientific method, through which the impacts and causes of the current environmental problems would be addressed. Additionally, the scientific method would sit at the basis of the future actions to be taken. These would traditionally include:
The search for alternative sources of energy
The search for renewable sources of energy
The creation of an infrastructure which allowed the propagation and populous use of alternative energies
The education of the population to reduce their levels of consumerism to life necessities
The implementation of stricter regulations which punish economic agents who pollute waters or cut the forests in an unsustainable manner
eplant forests, clean waters and support the sustainable life of the endangered species.
At a smaller size and specific level, the alternative and immediate action to be taken is that of reducing the harvesting of krill by commercial fishermen. This would be achieved…… [Read More]
This means that the fishing industry today has a responsibility to manage the available resources well, so that the entire industry will not be forced to collapse, and what is an important part of this is that development of the industry can no longer be based on increased catches of fish. (Past, present, and possible future of the fishery industry)
For appropriate research on the herring, the New England Fisheries Department has formulated a plan that would make this type of research more beneficial to fishermen and others concerned, and what the research involves is that one must continue to develop and use the inshore as well as the newly formed 'acoustic' trawl surveys in order to estimate stock sizes, and also to develop tagging and morphometric studies for the study of the herring. (New England Fisheries Management Council, esearch priorities)

Another major competitor in the Hong Kong market is COFCO (China National Cereals, Oils and Foodstuffs), which competes in the canned ready meal market and holds a 51% share there. All ready meals can be considered competitors for Tassal. COFCO is a Chinese brand with a major Hong Kong subsidiary. Another major competitor is Kraft, which markets a wide variety of all food products, including some ready meals (Market Research Centre, 2006).
The fragmented nature of the industry and the multiple distribution channels gives rise to an interesting industry dynamic. Firms can be intensely competitive, but for the most part they compete against one their own merits, rather than against one another. This allows new entrants to gain access to the market without significant backlash. ith multiple distribution channels available, there are many ways for firms to enter the Hong Kong market. Competition is based on a wide range of…… [Read More]
Women and water in India. In the villages of North Gujarat in India, so much groundwater has been removed that water supplies are now becoming scarce, according to hawana Upadhyay, writing in the journal Agriculture and Human Values. Women in North Gujarat are basically looked upon as "…domestic water users while men are seen as productive water users, despite the fact that women make significant use of water for productive purposes as well"
(Upadhyay, 2005, p. 411). Domestic water usage in India goes well beyond drinking and cooking, Upadhyay writes. Dalit women in Nepal for example grow commercial vegetable crops with the water they draw; they utilize a drip system, which costs just $12 to install, and it results in a profit of around $80 annually. Without a source of safe water, the livelihood of these women would disappear. Still, women's use of water tends to be classified as domestic,…… [Read More]
These gunboats would devastate wildlife area and other immense and indefinite environmental impact. These tankers would carry liquefied natural gas or LNG in cruising through Head Harbor Passage. It would take at least 90 minutes for each tanker, the size of Queen Mary, to cross the passage of whale and porpoise feeding areas, breeding grounds and nurseries as well as aquaculture sites and fishing grounds (Figart).
The Passamaquoddy people and their ancestors have, for thousands of years, lived, fished, hunted and cultivated land in the Quoddy region (Harvey, 2004). They have thrived on marine species for survival. ut over 200 years of permanent European settlement in the region since the late 18th century introduced environmental predators and developers. With the passing of the years, they increased and became more and more efficient (Harvey). In response to the situation, the United Nations Environment developed the Global Programme of Action…… [Read More]
This seafood research paper will outline some basic facts about striped bass, one of the most succulent fish served in the United States. Basic information about striped bass, including market information, use in menus, potential parasites, commercial fishing information and seasonality is included.
Striped bass is also known as striped bass, striper, linesider, bass, rockfish, rock, sewer trout and Fr. bar raye. The scientific name for striped bass is Morone saxatilis, and the fish appears in some early scientific literature as Roccus lineatus. Striped bass is a member of the medium- to large-sized, perch-like fishes, and inhabits coastal marine, brackish, and fresh waters in both temperate and tropical regions. This fish species was successfully introduced in into both a large number of inland lakes and reservoirs, and the Pacific coast. Striped bass now are resident from Ensenada, Mexico to British Columbia.
Along the Atlantic coast, most…… [Read More]
Powerful Stakeholder Policy to Prevent Industrial Environmental Impact
Friedman's stakeholder theory emphasizes the critical function of stakeholders in determining company's goals and responsibilities. Responsibility in a corporation is stated as individual role of each employee and manager to act and report to the upper level and finally to the decision-making boards.
As the top-level management and decision makers, corporate directors address their responsibility to the stakeholders, literally as the "owners" of the company, to whom all the running processes in the company, goal settings, and money spent should be reported. To follow the track, a manager is tied to what his/her employers have defined in the tasks list. Whatever skills and creativity managers possess must be utilized within the range of responsibility they have to the stakeholders, as stakeholders are the top decision-making board.
Company directors act based on the interest of shareholders as stakeholders. Scholl reads them as the…… [Read More]
Measurements were obtained both in the presence of and the absence of whale watching boats. It was observed that a period of intense boating activity caused the killer whales to adjust their call duration levels to compensate for the background noise. This clearly indicates that anthropogenic noise levels directly interfere with the routine life of the killer whales, which are dependent on vocal communication for successful hunting and survival. [Andrew et.al. 2004]
It is well-known that anthropogenic sounds can even have fatal consequences as evidenced by the recent mass strandings of beaked whales that coincided with the mid frequency sonar exercises by the navy. A recent research by (Holt et.al, 2009) focused on the effects of anthropogenic sounds on the vocal behavior of killer whales. The resident killer whales of the waters of the Puget Sound, Seattle, were the subjects of this study. The southern resident killer whales in three…… [Read More]
These proteins include homologous members of yeast. The presences of these proteins suggest that E. histolytica is skilled to perform homologous recombination, which is the same as in other organisms. DNA damage was evaluated by TUNEL assay. In yeast and in human cells, histone H2AX becomes rapidly phosphorylated when DSs are introduced into chromatin (Lavi et al.).
Studies show that histone as a protein plays a significant role in the transition between the expression of a fetal gene and that of the adult gene. The adult gene's metabolism becomes oxidative in order to adapt to air and to weight, as it generates methylated transmitters and creatine phosphate. The muscles get used to life on the ground as compared to the fetal life which takes place in an aquatic environment. Regulated proteins allow the muscles to respond in a more adequate manner to this environment.
Now, let us see how histone…… [Read More]
The government should create more incentives to use energy efficient alternatives, and they should be developed so that more people can afford them and use them.
Another solution, although extremely unpopular, it to tax carbon emissions. Some experts propose a worldwide tax of $50 per ton, which would tax industries that create greenhouse gases (Johansen 256). While this would not instantly solve the problem, it would encourage industries to develop alternatives to fossil fuels, and this could help reduce emissions while setting aside some of the tax funds to help combat global warming in other ways. Of course, industries reliant on fossil fuels are extremely opposed to the idea, and the tax would add costs to everyday items such as gasoline, oil, and coal.
The science and history of global warming defend this solution. Global warming has increased more in the last 100 years than it has at any time…… [Read More]
Another consequence of the exploitative use of water resources is the destruction of mangrove forests and the fragmentation of the habitats of endangered species. The United Nations Convention on International Trade in Endangered Species of Wild Flora and Fauna listed 189 endangered species in China among the 740 in the world.
Sand content is quite high in the Yellow iver. In the dry season, sand rises and flies up with the wind and soil desertization becomes severe. In addition, the iver's dri-up directly reduces the quantity of water for farmland irrigation. The supply of ground water decreases while the exploitation quantity of ground water increases. The results would include a deep crescent of ground water, a decrease of land evapo-transpiration, local climate drying, soil desertization, a reduction of biotic population and a simplification of biocommunity structure.
Another serious problem confronted in the Yellow iver is nitrogen contamination. A study found…… [Read More]
And so, as a solution, aquaculture farms are beginning to be created near Anchorage, raising cod, shrimp, and other fishes. This rising industry will attract newcomers to the area, which takes a certain hearty type because of the long cold winters. The labor force averaged 158,071 workers in 2006 (www.labor.state.ak.us).Alaska ranks #3 in oil production in the U.S., #1 in fisheries, and #1 in ports in National Marine Fisheries. Also, tourism is a big industry in Anchorage, and indeed 10% of the jobs are in leisure and hospitality sectors.
Anchorage history: it was first inhabited by humans in 5,000 B.C.; a "wave" of humans arrived around 3,000; then another "wave" arrived in 2,000 B.C., and Eskimo peoples and Dena'ina peoples made their home there before Europeans arrived in 1778 (www.ci.anchorage.ak.us).

9% of the turtles" -- and "plastics" dominated the debris found (Katsanevakis, p. 75). The list of plastic trash found in those turtles is too long to include in this research.
Seabirds (especially pelicans, gannets and gulls) often fall prey to "monofilament line"; albatrosses, petrels, penguins and grebes are not found entangled in plastic fishing line or other plastic debris as often as pelicans and gulls (Katsanevakis, 2008, p. 69). hat is particularly insidious about plastic is when it is ingested by marine animals is releases "toxic chemicals" due to the chemical additives that are added to the plastic during the manufacturing process. Once in the abdomen of the animal the toxic materials can block the digestive tract and block "gastric enzyme ingestion, diminished feeding stimulus, nutrient dilution, reduced growth rates, lowered steroid hormone levels, delayed ovulation and reproductive failure," Katsanevakis asserts (p. 71).

law help protect the environment and what steps can citizens take to ensure that the law accomplishes this goal?
Protection of the environment is important for our health, but humans affect the system through various means such as through polluting water and atmosphere with toxic gasses, with oil, with car fuels, and with debris that is plunked into the waters as well as depleting the fisheries and filling the air with smog and the earth with pollution.
It is for this reason that legislation is put into effect to curb our destruction and to teach us how to look after the environment in better ways. The state employs its own regulations, but it needs a synthesis of both state, business and citizen involvement to safeguard the environment, and motivation from both business and citizen is not always forthcoming. The following essay discusses policies that have been implemented to help protect…… [Read More]
Annelids are members of the Superphylum Lophotrochozoa. The division of the Phylum is in three classes Hirudineans (leeches), Oligochaetes (earthworms) and Hirudinean (Polychaetes and leeches). They inhibit marine aquatic with Parapodia, like nereis Meglitsch P, 1972()
They are worm like animals that have muscular body walls that elongate. They are also circular in cross section. The major difference between Phylum Annelida and other worm like creatures is that, they have segmented bodies (also known as metameric). Each segment has its own particular function. Phylum Annelida include different types of earthworms, leeches and marine polychaetes. There are those that live in fresh water, marine also terrestrial. Some of them live as parasites. Annelids are skilled in swimming, creeping and burrowing Badea, Gagyi-Palffy, Stoian, & Stan, 2010

Gender and Smell Recognition
WHOSE IS SHARPER?
It is common belief that women have a sharper sense of smell than men. However, there are separate studies suggesting that the sense is as strong in men as in women. Can women really identify smells better than men? Is women's sense of smell stronger in detecting certain types of scents, like cologne and perfume?
Feminine Smelling Ability Superior
Standard tests establish the superiority of women's smelling ability to that of men in terms of odor detection, discrimination and identification (SIRC, 2012). Women convincingly scored higher than men in these tests. A research said that this capability in females was shown in studied female newborns. ut other studies can refute this established finding. A separate study hinted that this feminine capability may be stronger to certain scents but not to others. Female sensitiveness to smell has been demonstrated to be 10,000 stronger to…… [Read More]
As for how this hurts Ecuador: shrimp is Ecuador's third-largest export, and many thousands of Ecuadorians are employed in the shrimp farming industry, Coglitore added.
Stevens - the American Seafood Distributors Association president - said the "zeroing" strategy guarantees that dumping margins can be used against foreign shipments. "The whole process just defies logic," he said.
This is "absolutely the worst time to be placing more taxes on the shrimp industry," said Brian Wynn, who is CEO of ubicon esources in Los Angeles, a major Thai shrimp importer, according to an article in the Asia Africa Intelligence Wire (January, 2005). "Together with the tsunami, there are real questions about the viability of the Thai shrimp industry."
Meanwhile, on the subject of the tsunami: "Officials within both sectors say that the World Trade Organization, international aid groups, and some of the stricken countries want the U.S. To drop tariffs or forgive…… [Read More]
Promotes better plant growth by improving the value of fertilizer. Helps prevent plant burning from over use of fertilizers by trapping and slowly releasing valuable nutrients when and as the plants need them.
Improves the cation exchange capacity of soil resulting in less fertilizer requirements.
Natural zeolites make an excellent soil amendment, and are environmentally friendly for landfill dump sites (with the exception of zeolite that has been used as a molecular sieve or filter medium for the removal of radioactive waste or the removal of heavy chemical toxins deemed hazardous by government regulations.)
educes nutrient and fertilizer loss through heavy rains, leaching and irrigation, resulting in less environmental damage through water runoff.
The water retention capability of zeolites allows less irrigation applications.
Zeolite is used to reduce offensive odors, especially ammonia from sewage, animal manure and waste water situations.
This retained valuable nitrogen improves the quality of the resulting…… [Read More]
K-12 Curriculum and Instruction: Changing Paradigms in the 21st Century
This is not your grandfathers' economy or his educational paradigm however; today's curriculum still appears as such and therein lays a very significant and challenging problem that presents to today's educators and leaders. According to Sir Ken Robinson, "We have a system of education that is modeled on the interest of industrialism and in the image of it. Schools are still pretty much organized on factory lines -- ringing bells, separate facilities, specialized into separate subjects. We still educate children by batches." (rain Pickings, 2012) Make no mistake in the opinion of Robinson who believes that divergent thinking most emphatically is not "…the same thing as creativity" because according to Robinson in his work proposing a new educational paradigm.

A BIEF synopsis of the Australian Blueberry Industry
Introductory Production Information
Australian and World production
Seasonal growth cycle
Native to North America, the blueberry, is also known as bilberries, whortleberries and hurtle berries, (Filippone 2006). The blueberry is a member of the Ericaceae, or Heather family and its growth was regulated by the indigenous peoples of North America (Agriculture and Agri-Food Canada 2005). Blueberries are of the genus Vaccinium, which originates from the Latin word vacca, which means cow. Captain James Cook, circa late 1700s, noted in his records that cows really liked to eat this tasty berry (Filippone 2006). The first European settlers recognized these berries to be analogous to kinds of berries found in their land of birth. For example, there's the blaeberry which is found in Scotland, whortleberries in Ireland, bilberries in Denmark, blabar in Sweden,…… [Read More]
Operating/ethical guidelines of International Trade. The objective of this paper is to discuss issues associated with the expansion of international trade related to pollution, worker rights, and product safety/standards and issues associated with property rights/trade secrets when operating in multiple countries.
The expansion of international trade has its pros and cons. On one hand it increases communication between countries on the other hands issues like pollution, worker rights, product safety become extremely important and sometimes need immediate attention. There are a number of organizations, which make sure that there is no exploitation of foreign workers at any time but international trade may promote exploitation of foreign workers and they try hard to eliminate all sweatshops and stop child labor.

Perhaps no other aquatic species contributes to oceanic ecology like the Brine Shrimp. Brine shrimp is a form of zooplankton. It is versatile in its physical and chemical characteristics. Its hardiness and survivability make it very special for preservation. It is sold for home aquariums. It has a fantastic ability to adapt to vagaries of temperature, oxygen content in the water and salinities. Its attractive to home aquariums is the almost chameleonic range of colors it can adopt based on its food intake. Brine shrimp have an elongated body and eleven pairs of legs. That is why they are confused with shrimp and the name.
Brine shrimp are also known as Artemia salina -- which is more of a generic name and several varieties of brine shrimp are in existence. They are arthropods that belong to the class of crustaceans. As zooplankton, one can consider them a major…… [Read More]
Human esource Management in Multinational Banks in Tanzania
ealization of effective management of operations and resources in the financial institutions is a dream for most organizations globally. Providing services that aim at meeting consumer needs becomes a key determinant that influences the realization of the stated objectives. In specific, providing services that empower the employees ensure the realization of the planned objectives as it creates the desired organizational culture of excellent performance. Analysis of different companies shows that the variance in the performance arises from the manner in which operations are managed (Wilkinson, 2009). Therefore, the following analysis compares and diagnoses the management of human resources of two multinational banks in Tanzania. The analysis illuminates the light into the different factors that influence effective management of operations in an organization.
