Escaped farmed salmon are then capable of spreading these infections to wild Pacific salmon populations. Of course, the big question is, “What can we do about these problems?” The best approach according to Frazer & Lewis (2008; as cited in SeaWeb, 2007), would include “… locating sea cages very far from wild fish” (Abstract), or using a “closed containment” (p. 2) system in order to isolate farmed fish from wild fish. Unfortunately, both options are more expensive than popular methods of aquaculture. Short-term gains from aquaculture and other human interventions appear to outweigh short-term losses, so industry has little incentive to follow more sustainable practices. If these practices continue, then long-term losses may result in the extinction of multiple Pacific salmon species
Close to the likely locations of these hotels, the environmental cost will likely be payed by the mangroves due to their unattractiveness by the mainstream tourist. This phenomenon of people flooding the region is likely to occur not only the reef, but in the mangroves as well. The only reason the degradation of the mangrove and coral reef habitats is occuring is a result of this coasts’ high potential for a beautifully, healthy, and bio-diverse community.
Scientific Name: Pomatomus saltatrix Common Name: Blue Fish Culture method: Hook and line, pound nets, seines, and trawls. Where/How harvested: The majority of bluefish are caught by recreational fishermen. Most commercial fisheries for bluefish use gillnet, but other types of nets are used to a lesser degree (generally small mesh nets). Sustainability: “Sustainability is about balancing the economic and nutritional needs of today with preservation of ocean resources for tomorrow.” Sustainability has emerged as a result of significant concerns about the unintended social, environmental, and economic consequences of rapid population growth, economic growth and consumption of our natural resources.

2009). This program would now be called Save the Tasmanian Devil Program (ibid.). The main aim of this program is “to maintain the Tasmanian Devil as an ecologically functional species in the wild” (AUSVET 2005), where research and conservation would be done in order to help to eliminate the apparent decrease of the species (IUCN, 2008). In regard to this project program, four management methods have been taken to protect the Tasmanian devil (ibid.). Firstly, insurance of Tasmanian devil population and breeding program are employed (ibid.).
If the cost of installing new defences is met by the benefit of the area, then a SMP (Shoreline Management Plan) is developed. An SMP (Shoreline Management Plan) is a large-scale assessment of the risks associated with coastal processes and helps reduce the risks to people, agriculture and infrastructure. The organisation responsible for the SMP in north Norfolk is the Environment Agency. The SMP for North Norfolk has been split into two sub cells to make managing easier: Sub cell 3A and Sub cell 3B. Overstrand, Sea Palling, Happisburgh and Bacton are located in Sub cell
He makes it clear to the audience that the development of the reef into a marina will be the loss of 'something precious' and will lead to the 'franchise, chlorination and sterilisation' of the wildlife. He appeals by giving examples of the 'wilderness experience' that is the reef. By using the rhetorical question 'how many places can you go to where you can swim with a whale shark, be circled by manta rays and see a dugong' he is showing the audience the uniqueness of the location, giving more reason for the protection and the prevention of the development. He also takes an attacking argument on the 'five star resorts' of the world, saying that when people return from a holiday, they do not remember the 'shopping mall like' hotels, 'seen one, seen them all' type buildings, unlike nature which is unique and diverse in each location. Why replace uniqueness with
It describes how the Bluefin is viewed in many different lights either as food or an economic goldmine to those that fish them, legally or illegally and how powerless the authorities are to stopping the underground trade. They then present the idea that there is only way to preserving the species; by commercial fish farming in protected waters. Overfishing and Fisheries Management: Stocks of commercially fished species must be managed carefully to ensure that the catch (take) does not undermine the sustainability of the fishery. In Australia, about 50 species make up 85% of the commercial catch. The most important species are either fully exploited and are being managed to achieve a sustainable yield, or have been overexploited and are now being managed to allow recovery.
These people also think that it opens the California dams to a whole host of nonfood genetically engineered organisms. Well, they do have a point, but, how would the Glofish get to the dams? A great thing about Glofish is that they can detect when they are in polluted water. These fish swim light up and swim away from areas of polluted water.” Glofish are a helpful resource to today’s society.
Outline 3 reasons why it is important to protect the Hunter River Estuary from environmental harm. The Hunter River Estuary is an important site for migratory shorebirds and home to a range of fish and crustaceans. The Lower Hunter region is part of a transition zone for many plant and animal species between the sub-tropical influences of the north and the cooler conditions of the south. As a consequence the vegetation and fauna species is unique to neighboring regions. 6.
It is important to research on ways of controlling draught and limiting algae growth because it will mitigate further expansion of the Gulf of Dead Zone. References Bruckner, M. (2012).
