Fishing In Australia
Seafood in Australia comes from local and international commercial fisheries, aquaculture and recreational anglers. It is an economically important sector, and along with agriculture and forestry contributed $24,744 million to Australia's GDP in year 2007–2008, out of a total GDP of $1,084,146 million. Commercial fisheries in Commonwealth waters are managed by the Australian Fisheries Management Authority, while commercial and recreational fishing in state waters is managed by various state-level agencies. The sustainable seafood movement is growing in Australia as consumers become more aware of conservation issues and the importance of maintaining Fish stocks, fish stocks. Organisations such as the Marine Stewardship Council and Australian Marine Conservation Society'GoodFish: Australia's Sustainable Seafood Guidehave released guides helping consumers make sustainable seafood choices.

Aquaculture
Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. Nelumbo nucifera, lotus). Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems. Mariculture, commonly known as marine farming, is aquaculture in seawater habitats and lagoons, as opposed to freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain Fish as food, fish products as food. Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environme ...

Fish In Australia
Australia has over 5000 described species of fish, a quarter of which are endemic. Seafood and aquaculture are major and highly regulated industries, and fishing for marine and freshwater native fish is popular. Species of freshwater fish For its land-size, Australia has a low diversity of native freshwater fish with only 281 described species. This is largely because Australia is a very dry continent with sporadic rainfall and large areas of desert. There is a higher diversity of salt water fish. The most common freshwater fish are: *Murray cod * Australian bass Other species include: * Australian grayling * Australian smelt * Climbing galaxias * Common galaxias * Eastern freshwater cod * Eel-tailed catfish * Estuary perch * Flathead galaxias * Golden perch * Halfbeak/Garfish * Jardini * Inanga * Macquarie perch * Mary River cod * Mountain galaxias * Queensland lungfish * Rainbowfish * Retropinnidae * River blackfish * Saratoga * Salamanderfish * Short-fin ...

Marine Conservation
Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources. Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by response to the manifested negative effects seen in the environment such as species loss, habitat degradation and changes in ecosystem functions and focuses on limiting human-caused damage to marine ecosystems, restoring damaged marine ecosystems, and preserving vulnerable species and ecosystems of the marine life. Marine conservation is a relatively new discipline which has developed as a response to biological issues such as extinction and marine habitats change. Marine conservationists rely on a combination of scientific principles derived from marine biology, Ecology, oceanography, and fisheries science, as well as on human factors ...

Environmental Issues In Australia
Environmental issues in Australia describes a number of environmental issues which affect the environment of Australia and are the primary concern of the environmental movement in Australia. There are a range of such issues, some of the relating to conservation in Australia. Others, for example the deteriorating state of Murray-Darling Basin, have a direct and serious effect on human land use and the economy. Many human activities including the use of natural resources have a direct impact on the Australian environment and its ecology. Additionally Australian Aboriginal culture, Aboriginal culture has a strong connection to the land, with some landscape features considered sacred, and as such environmental damage to Australian Aboriginal sacred sites can also have significant cultural repercussions. Some of the key issues include: Climate change in Australia, climate change; contamination and pollution; ozone depletion; conservation; Invasive species in Australia, invasive spec ...

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas and transboundary protected areas across multiple borders. As of 2016, there are over 161,000 protected areas representing about 17 percent of the world's land surface area (excluding Antarctica). For waters under national jurisdiction beyond inland waters, there are 14,688 Marine Protected Areas (MPAs), covering approximately 10.2% of coastal and marine areas and 4.12% of global ocean areas. In contrast, only 0.25% of the world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; this ...

Conservation In Australia
Conservation in Australia is an issue of state and federal policy. Australia is one of the most biologically diverse countries in the world, with a large portion of species endemic to Australia. Preserving this wealth of biodiversity is important for future generations. 25% of Australia is managed for conservation. Animal habitats like reefs and forests must be preserved in order to preserve the population and diversity of animal species. Conservation is vital for future study and for field research to be taken, and because biological richness is an unmeasurable aesthetic that may be developed into commercial recreational attractions. According to Janine Benyus, the potential for advances in biomimicry in Australia is great because the extreme weather and conditions found here provide an excellent evolutionary incubator. Research on natural processes can only occur if the habitat is preserved and organisms continue to thrive. Federal and State governments manage protected are ...

Agriculture In Australia
Although Australia is mostly arid, the nation is a major agricultural producer and exporter, with around 421,000 people employed in agriculture, forestry and fishing as of 2023. Agriculture's farm gate output was $100 billion a year for a 5.7% share of GDP in 2023. Farmers and grazers own 135,997 farms, covering 61% of Australia's landmass. Across the country, there is a mix of irrigation and dry-land farming. The success of Australia in becoming a major agricultural power despite the odds is facilitated by its policies of long-term visions and promotion of agricultural reforms that greatly increased the country's agricultural industry. There are three main zones: the high rainfall zone of Tasmania and a narrow coastal zone (used principally for dairying and beef production); wheat, sheep zone (cropping (principally winter crops), and the grazing of sheep (for wool, lamb and mutton) plus beef cattle) and the pastoral zone (characterised by low rainfall, less fertile soils, a ...

Fisheries Observer
A fisheries observer is an independent specialist who serves on board commercial fishing vessels, or in fish processing plants and other platforms, and is employed by a fisheries observer program, either directly by a government agency or by a third party contractor, such as the Northwest Atlantic Fisheries Organization. Observers spend anywhere from one day to three months with the vessel, recording data on catch composition, biological sampling, and fishing activity. After returning to land, the observer is debriefed, which involves reviewing any unusual occurrences or observations, violations observed, and any safety problems or other hardships they endured during the trip. These data are then integrated into the regional agency’s database used to monitor fish quotas. Observers are usually the only independent data collection source for some types of at-sea information, such as bycatch, catch composition, and gear configuration data. Independent data collection in this co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquaculture In Australia
Aquaculture in Australia is the country's fastest-growing primary industry, accounting for 34% of the total gross value of production of Seafood in Australia, seafood. 10 species of fish are farmed in Australia, and production is dominated by southern bluefin tuna, Atlantic salmon and barramundi. Scylla serrata, Mud crabs have also been cultivated in Australia for many years, sometimes leading to over-exploitation. Traditionally, this aquaculture was limited to table oysters and pearls, but since the early 1970s, there has been significant research and commercial development of other forms of aquaculture, including Fin-fish, finfish, crustaceans, and Mollusca, molluscs. Australia produces 240,000 tonnes of fish a year with aquaculture contributing a third to this. Over the decade to 2006–07 aquaculture production has almost doubled from 29,300 tonnes to 57,800 tonnes. The gross value of aquaculture production in Australia continued to rise in 2007–08 by $62.7 million to $868 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish And Chips
Fish and chips is a hot dish consisting of batter (cooking), battered and fried fish, served with French fries, chips. Often considered the national dish of the United Kingdom, fish and chips originated in England in the 19th century. Today, the dish is a common Take-out, takeaway food in numerous other countries, particularly English-speaking and Commonwealth of Nations, Commonwealth nations. Fish and chip shops first appeared in the UK in the 1860s, and by 1910 there were over 25,000 of them across the UK. This increased to over 35,000 by the 1930s, but eventually decreased to approximately 10,000 by 2009. The British government safeguarded the supply of fish and chips during the First World War and again in the Second World War. It was one of the few foods in the UK Rationing in the United Kingdom, not subject to rationing during the wars, which further contributed to its popularity. History The British tradition of eating fish battered and fried in oil may have been i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Random Sample
In this statistics, quality assurance, and survey methodology, sampling is the selection of a subset or a statistical sample (termed sample for short) of individuals from within a statistical population to estimate characteristics of the whole population. The subset is meant to reflect the whole population, and statisticians attempt to collect samples that are representative of the population. Sampling has lower costs and faster data collection compared to recording data from the entire population (in many cases, collecting the whole population is impossible, like getting sizes of all stars in the universe), and thus, it can provide insights in cases where it is infeasible to measure an entire population. Each observation measures one or more properties (such as weight, location, colour or mass) of independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly in stratified sampling. Results from probabil ...
