The family is made up of four extant (living) genera: The genera Astacus (which includes the European crayfish), Pontastacus (which includes the Turkish crayfish), and Austropotamobius are all found throughout Europe and parts of western Asia, while Pacifastacus (which includes the signal crayfish) is native to western United States and British Columbia, but has also been introduced elsewhere. (wikipedia.org)
The Italian crayfish was introduced to Spain in the 16th century, and spread due to multiple stocking events until the 1970s, when two North American crayfish (red swamp crayfish Procambarus clarkii, and signal crayfish Pacifastacus leniusculus) were introduced. (bvsalud.org)
Species of the genus Astacus are particularly susceptible to infection, allowing the more resistant signal crayfish to invade parts of Europe . (roeselienraimond.com)

Most crayfish cannot tolerate polluted water , although some species, such as Procambarus clarkii , are hardier. (wikipedia.org)
The term "crayfish" is applied to saltwater species in some countries . (wikipedia.org)
Both North American species are carriers of a pathogen (Aphanomyces astaci, the causal agent of crayfish plague) lethal to the Italian crayfish. (bvsalud.org)
Crayfish plague was transmitted to Europe when North American species of crayfish were introduced. (roeselienraimond.com)
Lobsters1
Crayfish [a] are freshwater crustaceans belonging to the clade Astacidea , which also contains lobsters . (wikipedia.org)
Astacidae2
Astacidae is a family of freshwater crayfish native to Europe, western Asia and western North America. (wikipedia.org)
Astacidae belongs to the superfamily Astacoidea, which contains all crayfish in the Northern Hemisphere. (wikipedia.org)
Parastacoidea2
Astacoidea is the sister taxon to Parastacoidea, which contains all crayfish of the Southern Hemisphere. (wikipedia.org)
Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea . (wikipedia.org)
Hemisphere1
There are three families of crayfish, two in the Northern Hemisphere and one in the Southern Hemisphere . (roeselienraimond.com)
Freshwater1
from the Parastacidae family Tasmanian giant freshwater crayfish found only in Tasmania, and the Murray crayfish found on Australia's Murray River . (roeselienraimond.com)
Plague1
Some crayfish suffer from a disease called crayfish plague , caused by the water mould Aphanomyces astaci . (roeselienraimond.com)
Crustaceans1
Like other edible crustaceans, only a small portion of the body of a crayfish is eaten. (roeselienraimond.com)

2021. Genetic diversity and structure of the noble crayfish populations in the Balkan Peninsula revealed by mitochondrial and microsatellite DNA markers. (kmae-journal.org)
We used 19 microsatellite loci and the cytochrome oxidase subunit I (COI) gene to assess population connectivity and genetic diversity of the Pristine Crayfish. (researchsquare.com)
North American2
After the introduction of the North American crayfishes, the collapse of the Italian crayfish involved a niche shift towards rough terrains in mountain areas. (bvsalud.org)
North American crayfish have eventually occupied most of the Italian crayfish's niche space, with the few no-coexistence areas being relegated to the most abrupt and high-elevation territories. (bvsalud.org)
Found2
The two morphologically distinct forms of the Pristine Crayfish are found in the upper Caney Fork (nominal Caney Fork form) and the Big Brush Creek and Cane Creek systems (Sequatchie form). (researchsquare.com)
Fossil records of crayfish older than 30 million years are rare, but fossilised burrows have been found from strata as old as the late Palaeozoic or early Mesozoic. (roeselienraimond.com)
Animals and plants2
Crayfish feed on animals and plants, either living or decomposing , and detritus . (wikipedia.org)
In Singapore , the term crayfish typically refers to Thenus orientalis , a seawater crustacean from the slipper lobster family. (roeselienraimond.com)
Range2
We conducted a population genetics and phylogeographic assessment of the imperiled Pristine Crayfish ( Cambarus pristinus ) sampled throughout its range encompassing two morphologically distinct forms. (researchsquare.com)
We hypothesised that the realised niche of the Italian crayfish, both in breadth and in position, has changed over time following changes in its range. (bvsalud.org)
Shown1
Also crayfish have been shown to be coprophagic - eating their own faeces, they also eat their own exuviae ( moulted carapace ) and each other. (wikipedia.org)
World1
Crayfish all over the world can be seen in an ecological role of benthic dwellers, so this is where most of their food is obtained - at the sediment/water interface in ponds, lakes, swamps, or burrows. (wikipedia.org)
Distribution3
Here, we analysed the distribution and niche dynamics of the Italian crayfish (Austropotamobius fulcisianus) in the Iberian Peninsula over the past 200 years. (bvsalud.org)
The distribution of the Italian crayfish expanded from the mid-19th century until the mid-20th century, in association with an enlargement of its realised niched, mostly towards less abrupt and more coastal-influenced areas. (bvsalud.org)
Our historical approach allowed us to document and understand the highly dynamic distribution and niche of the Italian crayfish in the presence of invader counterparts, and to explore the environmental conditions under which their coexistence is minimised. (bvsalud.org)
