Modelling habitat requirements of white-clawed crayfish (Austropotamobius pallipes) using support vector machines

Knowledge and Management of Aquatic Ecosystems, 2011
The white-clawed crayfish’s habitat has been profoundly modified in Piedmont (NW Italy) due to environmental changes caused by human impact. Consequently, native populations have decreased markedly.

CRAYFISH PREDATION EXPERIMENTS ON THE INTRODUCED ZEBRA MUSSEL, DREISSENA POLYMORPHA, IN IRELAND, AND THEIR POTENTIAL FOR BIOCONTROL.

Knowledge and Management of Aquatic Ecosystems, 2001
The zebra mussel Dreissena polymorpha, native to the Aralo-Caspian region, has spread across Europe in the last 180 years. Although it reached England in 1820, it only arrived in Ireland in around 1995, probably attached to the hull of pleasure boats ...

HIGH DISPERSAL ABILITY OF AUSTROPOTAMOBIUS PALLIPES REVEALED BY MICROSATELLITE MARKERS IN A FRENCH BROOK

Knowledge and Management of Aquatic Ecosystems, 2002
The genetic structure of a large population of the white-clawed crayfish Austropotamobius pallipes was assessed with five microsatellite markers by sampling six sites along its extent.

Two indigenous European crayfish under threat – how can we retain them in aquatic ecosystems for the future?

Knowledge and Management of Aquatic Ecosystems, 2011
Indigenous crayfish species (ICS) are under threat in Europe; due to competition from invasive non-indigenous crayfish species (NICS) from crayfish plague, which is carried by introduced American crayfish, and habitat degradation.

VITELLOGENIN AND GLUCOSE CONCENTRATIONS IN THE HEMOLYMPH OF WILD AND CONFINED CRAYFISH (AUSTROPOTAMOBIUS PALLIPES LEREBOULLET 1858)

Knowledge and Management of Aquatic Ecosystems, 2003
The white-clawed crayfish (Austropotamobius pallipes) is a native species in the Friuli Venezia Giulia region of North-Eastern Italy. This species is under threat because of habitat modifications and water pollution.

EFFECTS OF DEAD EGG REMOVAL FREQUENCY ON STAGE 2 JUVENILE PRODUCTION IN ARTIFICIAL INCUBATION OF AUSTROPOTAMOBIUS PALLIPES LEREBOULLET

Knowledge and Management of Aquatic Ecosystems, 2004
In artificial incubation (AI) of astacid species, which have a long embryonic development, eggs have to remain during long periods without maternal care and it is recommended to remove the dead ones.

Crayfish Plague and Microsporidiosis Occurrence in Wild Populations of the White-Clawed Crayfish Austropotamobius Pallipes Complex in Trentino (North-East Italy)

Journal of Invertebrate Pathology
One of the causes of the decline in distribution and abundance of the endangered white-clawed crayfish Austropotamobius pallipes complex throughout Europe is the invasion of alien crayfish, and the associated spread of infectious diseases, primarily the crayfish plague caused by Aphanomyces astaci.

The long-term effects and detection ranges of passive integrated transponders in white-clawed crayfish Austropotamobius pallipes

Knowledge and Management of Aquatic Ecosystems, 2018
Individual identification of the endangered white-clawed crayfish (Austropotamobius pallipes) can provide valuable information when assessing long-term survival of animals released into the wild; currently the most effective method is the use of passive ...

AN INVESTIGATION INTO THE DISAPPEARANCE OF AUSTROPOTAMOBIUS PALLIPES (LEREBOULLET) POPULATIONS IN THE HEADWATERS OF THE NORE RIVER, IRELAND AND THE CORRELATION TO WATER QUALITY

Knowledge and Management of Aquatic Ecosystems, 2003
Monitoring of the protected white-clawed crayfish Austropotamobius pallipes (Lereboullet) has been carried out in the headwaters of the Nore River since 1995. In recent years a reduction in crayfish abundance had become apparent.

Welfare considerations during a conservation translocation of white-clawed crayfish (Austropotamobius pallipes): Proof of concept

Animal Welfare
Translocations are a conservation method used to establish or supplement self-sustaining populations. However, research regarding the welfare implications of this strategy is limited, particularly in recipient wild populations.
