Transmission of crayfish plague [PDF]

Diseases of Aquatic Organisms, 2002
Two possible means of transmission of crayfish plague were investigated: via fish (as vectors), and via crayfish (as hosts or vectors when dead). The crayfish transmission experiments focussed on both the viability of the fungus in dead crayfish when kept in simulated field conditions, and on the treatments which kill viable forms of Aphanomyces astaci

Hungary: a European hotspot of non-native crayfish biodiversity

Knowledge and Management of Aquatic Ecosystems, 2020
There is a long history of crayfish introductions in Europe and numbers keep increasing. In Hungary, spiny-cheek crayfish Faxonius limosus, signal crayfish Pacifastacus leniusculus, red swamp crayfish Procambarus clarkii, marbled crayfish P.

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 ...

Non-consumptive effects of native, alien and invasive alien crayfish on damselfly egg life history and carry-over effects on larval physiology [PDF]

NeoBiota
Invasive alien (IA) predators pose significant threats to native ecosystems, often leading to profound impacts on prey species through both direct and non-consumptive effects (NCE). This study focused on the NCE of predator-induced stress from one native

Exponential increase of signal crayfish in running waters in Sweden – due to illegal introductions?

Knowledge and Management of Aquatic Ecosystems, 2011
Sweden has only one indigenous species of crayfish, the noble crayfish (Astacus astacus, Fabricius). There has been a steady decline of noble crayfish populations in Sweden since 1907, mainly due to the crayfish plague.

Native European crayfish Astacus astacus competitive in staged confrontation with the invasive crayfish Faxonius limosus and Procambarus acutus.

PLoS ONE, 2022
The European native, noble crayfish (Astacus astacus) has suffered from a serious and long term population decline due to habitat destruction, water pollution and the impact of the invasive North American crayfish that are carriers of the crayfish plague

Crayfish epidemics

Parasitology, 1956
Epidemics in English crayfish, Astacus pallipes, were found to be due to micro-sporidia and yeasts similar to, if not identical with, those causing diseases in another Crustacean, namely, Gammarus pulex, in many parts of England.
