THE EFFECT OF THE LARGE-SCALE INTRODUCTION OF SIGNAL CRAYFISH ON THE SPREAD OF CRAYFISH PLAGUE IN SWEDEN

Knowledge and Management of Aquatic Ecosystems, 2006
Since 1907, coinciding with the arrival of the crayfish plague, the noble crayfish (Astacus astacus) has steadily declined in Sweden. To substitute the noble crayfish fishery lost, mainly due to the plague, and since the species is highly susceptible to ...

Investigation of the first recent crayfish plague outbreak in Ireland and its subsequent spread in the Bruskey River and surrounding areas

Knowledge and Management of Aquatic Ecosystems, 2022
White-clawed crayfish (Austropotamobius pallipes) is a keystone species found in western European freshwater bodies, where it has suffered drastic declines due to pathogens, competition with non-indigenous crayfish species (NICS) and habitat ...

The signal crayfish is vulnerable to both the As and the PsI-isolates of the crayfish plague

Knowledge and Management of Aquatic Ecosystems, 2014
The carrier status and possible elevated tolerance of the signal crayfish (Pacifastacus leniusculus) against the crayfish plague disease agent (Aphanomyces astaci) has been speculated for several decades.

Confirmation of crayfish plague in Italy: detection of Aphanomyces astaci in white clawed crayfish [PDF]

Diseases of Aquatic Organisms, 2010
In the summer of 2009, high levels of mortality among white clawed crayfish Austropotamobius pallipes were observed in 3 watercourses of central Italy. PCR and culture methods were used to detect the causative agent of the disease. Two strains of Aphanomyces spp.

Controlled Infection Experiment With Aphanomyces astaci Provides Additional Evidence for Latent Infections and Resistance in Freshwater Crayfish

Frontiers in Ecology and Evolution, 2021
For 150 years the crayfish plague disease agent Aphanomyces astaci has been the cause of mass mortalities among native European crayfish populations. However, recently several studies have highlighted the great variability of A.

Invasive crayfish and crayfish plague on the move: first detection of the plague agent Aphanomyces astaci in the Romanian Danube [PDF]

Diseases of Aquatic Organisms, 2012
Native European crayfish, such as Astacus leptodactylus, are threatened, among other factors, by the crayfish plague agent Aphanomyces astaci, dispersed by invasive North American crayfish. Two of these invaders, Pacifastacus leniusculus and Orconectes limosus, have extended their distribution in the River Danube catchment; the latter was detected for ...

Simultaneous detection of native and invasive crayfish and Aphanomyces astaci from environmental DNA samples in a wide range of habitats in Central Europe [PDF]

NeoBiota, 2020
Crayfish of North American origin are amongst the most prominent high-impact invasive invertebrates in European freshwaters. They contribute to the decline of European native crayfish species by spreading the pathogen causing crayfish plague, the ...

Practical disinfection chemicals for fishing and crayfishing gear against crayfish plague transfer [PDF]

Knowledge and Management of Aquatic Ecosystems, 2014
We tested four commercial disinfectants against crayfish plague (Aphanomyces astaci) spores in both aquatic solutions and with material mimicking fishing and crayfishing gear, e.g. traps, ropes, mesh, etc. The tested disinfectants were Proxitane®5:14, Proxitane®12:20, Wofasteril®E400, Virkon®S and hydrogen peroxide.

Chronic crayfish plague infection and eroded swimmeret syndrome in Lake Saimaa (Finland) signal crayfish [PDF]

Freshwater Crayfish, 2017
Abstract We present data and results from a 9-year survey (2009 – 2017) of the Lake Saimaa signal crayfish population in Finland. This population has a history of chronic infection with Aphanomyces astaci. It has now been discovered that female signal crayfish from Lake Saimaa suffer from various stages of eroded swimmeret syndrome (ESS), and male ...
