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. 10 species of fish are farmed in Australia, and production is dominated by southern bluefin tuna, Atlantic salmon and barramundi. Mud crabs have also been cultivated in Australia for many years, sometimes leading to over-exploitation. Traditionally, this aquaculture was limited to pearls, but since the early 1970s, there has been significant research and commercial development of other forms of aquaculture, including finfish, crustaceans, and 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 million. In 2008 the Aquaculture industry directly employed more than 7000 ...

CSIRO ScienceImage 2686 Salmon Cages
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research began in Australia years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly and achieved significant early successes. In 1949, further legislated changes included renaming the organisation as CSIRO. Notable developments by CSIRO have included the invention of atomic absorption spectroscopy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Budj Bim Heritage Areas
Budj Bim heritage areas includes several protected areas in Victoria, Australia, the largest two being Budj Bim National Heritage Landscape and the Budj Bim Cultural Landscape. Within the latter, there are three Indigenous Protected Areas: the Tyrendarra Indigenous Protected Area, Kurtonitj Indigenous Protected Area, and the Lake Condah Indigenous Protected Area. All of the protected areas are related to the volcanic landscape created by the eruption of Budj Bim (Mount Eccles) more than 30,000 years ago, and the dormant volcano is included in the National Heritage and World Heritage sites (which also include Budj Bim National Park). The various areas are of great historic and cultural significance to various clans of the Gunditjmara, the local Aboriginal people: Budj Bim features in their mythology as a creator-being, and the Gunditjmara people developed an extensive system of aquaculture on the land created by the lava flows up to 8,000 years ago. Tae Rak (Lake Condah) form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marron
Marron is a name given to two closely related species of crayfish in Western Australia. Formerly considered a single species, it is now recognised as comprising two species, the critically endangered '' Cherax tenuimanus'', and the species that is outcompeting it, '' C. cainii''. Marron are considered a luxury product and are the subject of a developing aquaculture industry in Western Australia and other Australian states. Total Australian production of farmed marron was 30 tons in 1996. In Western Australia, recreational fishing for marron is tightly controlled, with a limited season, permits are required, and minimum sizes are enforced. Marron have been introduced to Kangaroo Island in South Australia South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories ..., where they have been co ...

Cherax Quadricarinatus
''Cherax quadricarinatus'' (known by several common names, including Australian red claw crayfish, Queensland red claw, redclaw, tropical blue crayfish, freshwater blueclaw crayfish) is an Australian freshwater crayfish. Distribution and ecology ''C. quadricarinatus'' is native to permanent freshwater streams, billabongs and lakes on the north coast of the Northern Territory, northeastern Queensland, and Papua New Guinea. Through translocation by humans, the range has spread down to southern Queensland and into the far north of Western Australia. ''C. quadricarinatus'' is considered an invasive species, and has established feral populations in South Africa, Mexico, Jamaica, Puerto Rico, Indonesia, Zambia, Malaysia and Singapore. This tropical crustacean is very tolerant of environmental changes, and is primarily a detritivore. Description The colour of ''C. quadricarinatus'' ranges from dark brown to blue-green and adult males have a distinct red patch on the outer margin o ...

Crayfish
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as ''Procambarus clarkii'', are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' (Modern French '). The word has been modified to "crayfish" by association with "fish" (folk etymology). The largely American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prawn
Prawn is a common name for small aquatic crustaceans with an exoskeleton and ten legs (which is a member of the order decapoda), some of which can be eaten. The term "prawn"Mortenson, Philip B (2010''This is not a weasel: a close look at nature's most confusing terms''Pages 106–109, John Wiley & Sons. . is used particularly in the United Kingdom, Ireland, and Commonwealth nations, for large swimming crustaceans or shrimp, especially those with commercial significance in the fishing industry. Shrimp that are present in this category often belong to the suborder Dendrobranchiata. In North America, the term is used less frequently, typically for freshwater shrimp. The terms shrimp and prawn themselves lack scientific standing. Over the years, the way they are used has changed, and in contemporary usage the terms are almost interchangeable. Shrimp'' vs. ''prawn Regional distinctions The terms shrimp and prawn originated in Britain. In the use of common names for species, shrim ...

Bidyanus Bidyanus
The silver perch (''Bidyanus bidyanus'') is a medium-sized freshwater fish of the family Terapontidae endemic to the Murray-Darling river system in south-eastern Australia. Taxonomy The silver perch's scientific name comes from an aboriginal name for the species – ''bidyan'' – recorded by Major Mitchell on the Barwon River on his 1832 expedition. (Mitchell's original scientific name for the species was ''Cernua Bidyana''.) Silver perch are not a "true" perch of the genus ''Perca'', but are instead a member of Terapontidae or 'grunter' family. They are the largest member of the Terapontidae, capable of growing in excess of and close to , but today wild river specimens are typically and . The silver perch is the only major representative of the family Terapontidae in the southern Murray-Darling system, compared to northern tropical systems where terapontid species are common.

Tuna
A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna (max length: , weight: ) up to the Atlantic bluefin tuna (max length: , weight: ), which averages and is believed to live up to 50 years. Tuna, opah and mackerel sharks are the only species of fish that can maintain a body temperature higher than that of the surrounding water. An active and agile predator, the tuna has a sleek, streamlined body, and is among the fastest-swimming pelagic fish – the yellowfin tuna, for example, is capable of speeds of up to . Greatly inflated speeds can be found in early scientific reports and are still widely reported in the popular literature. Found in warm seas, the tuna is commercially fished extensively as a food fish, and is popular as a bluewater game fish. As a result of overfishing, some tuna species, s ...
