Topic: Common yabby


In the News (Sat 28 Nov 09)

  
  Yabby - Wikipedia, the free encyclopedia
Yabby is a name given in Australia to two different kinds of crustacean.
Freshwater yabbies are crayfish of the genus Cherax (infraorder Astacidea, family Parastacidae).
Marine yabbies are ghost shrimps (infraorder Thalassinidea), which live in deep burrows in the intertidal zone.

 The Freshwater Yabby - NSW DPI - Fisheries   (Site not responding. Last check: 2007-11-01)
The common yabby forms an important part of the diet of white ibis, several cormorants, and warmwater fishes such as the Murray cod and the callop (golden perch or yellowbelly).
Substrate type is not critically important, although the yabby is commonly found on muddy or silted bottoms with the occasional rock or fallen branch (in contrast to the leaf-littered, rocky or pebbly streams of the spiny crayfishes).
The yabby is susceptible to insecticides and herbicides, particularly the organochlorines.

 Australian Aquaculture Portal
Because yabbies are an introduced species in Western Australia, the licensed yabby farming industry is restricted to the drier inland developed agricultural area of the south west, to the north of Perth and to the east of Albany.
Yabbies are produced mainly in existing dams and farm waterways as part of farm diversification.
Yabby ponds are an ideal use for land with heavy clay based soils that may be otherwise unproductive, and can represent an opportunity for diversification for farmers who have access to water and spare land.

Yabbies have large claws used for defence, holding food and digging.

 Yabby
The number of Yabby-holes over a flat often conveys a misleading impression of the density of these animals, for each adult Yabby may have three surface holes communicating with its main burrow, the walls of which are smoothed and compacted by its movements.
The adult male has one enormously-developed claw which is capable of giving a rather sharp nip; this feature is less well developed in the adult female, who may carry 2,000 eggs in a cluster under her abdomen.
Yabbies feed by straining out organic matter from the sand into which they have burrowed.

Yabbies are also cannibalistic, particularly where overcrowding occurs when a form of population control is exercised by yabbies eating their own kind.
Yabbies are a food source for aquatic birds and fish, and are a popular fishing bait and food for man, and are increasingly produced by commercial fish farms for both fishing bait and for restaurants, the yabby being considered a delicacy.
Yabbies are the semi-aquatic group of Australia's (and Victoria's) freshwater crayfishes.

Australian yabbies are in demand internationally due to their high quality, larger size than crayfish produced by overseas competitors, acceptance by European markets as a replacement for diminishing stocks of their own native crayfish, freedom from major diseases and ability to be landed live in the major international markets.
The yabbies remain in these tanks, where they are not fed, for a minimum of 48 hours to purge their hind guts and greatly improve the flavour and travelling condition.
A case study of the economics of harvesting yabbies from a farmer's dams was undertaken in 1996 by an extension officer employed by the Fisheries Department of WA.

 Yabbies
Yabbies are prolific breeders and spawn annually during the summer months in Victoria.
Feeding rates are between 2% and 4% biomass/day and the yabbies are fed artificial feeds, which are supplemented by natural feeds in the ponds.
Yabbies are popular domestically as table food and are also used as fish bait.

The live yabby can then be hooked lightly through the underside of the tail so the hook point comes out at the tip of the tail, making the yabby ride upright.
On the other side of the coin is the fact that yabbies are first class table fare and sometimes they are just too good to be used as bait.
The common yabby (cherax desructor) can be found in just about any western watershed in NSW (west of The Great Divide).

At the moment he estimates that most farmed yabbies are only one to five generations removed from their wild relations.
By injecting the yabbies with a fluorescent dye, researchers are able to monitor which family each animal is from to prevent inbreeding.
Even though there is confidence that there is a market for the yabbies, until there is the ability to produce consistently high numbers reaping the rewards of such substantial investment is not quite a reality.

 Crustacean Information
Although crustaceans are rarer as fossils than trilobites are, a number of different types of crustaceans are common in the rocks of the Cretaceous period as well as those of the Caenozoic era.
Most of the smaller crustaceans, such as shrimp, have an exoskeleton which is somewhat delicate and for this reason their fossil record is incomplete.

The decline of water quality, blooms of blue-green algae, contamination with pesticides, nutrients and sediment, microbes that threaten drinking water supplies, fish deaths, and the threats posed by increasing salinity are some of the widespread issues that affect many waterways in Australia.
