Better Alone Than in Bad Company: Trophic Ecology of Co‐Occurring Invasive and Native Crayfish [PDF]
Ecology and EvolutionThe North American signal crayfish, Pacifastacus leniusculus, is one of the most successful invasive crayfish species in Europe. Its broad trophic niche and ability to exploit various food sources across different trophic levels, coupled with the spread ...

Impacts of the North American signal crayfish (Pacifastacus leniusculus) on European ecosystems. [PDF]
Environ Sci Eur, 2015 As a vector of the crayfish plague (Aphanomyces astaci), invasive crayfish pose a major threat to endemic crayfish species in Europe. But do they affect whole ecosystems and fish species as well? A comprehensive review was done using online search engines on current literature to elucidate possible crayfish effects.

Reduced aggression and foraging efficiency of invasive signal crayfish (Pacifastacus leniusculus) infested with non-native branchiobdellidans (Annelida: Clitellata) [PDF]
Parasites & Vectors, 2015 Background Biological invasions are a principal threat to global biodiversity and identifying the determinants of non-native species’ success is a conservation priority.

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 ...

Potential impacts of invasive crayfish on native benthic fish: shelter use and agonistic behaviour [PDF]
NeoBiota, 2023 Spinycheek crayfish (Faxonius limosus) and signal crayfish (Pacifastacus leniusculus) are successful North American invasive crayfish species distributed throughout Europe. Both species compete with native benthic fish for shelter.

Three crayfish species of different origin in a medium-sized river system: a new state of affairs
Knowledge and Management of Aquatic Ecosystems, 2021 In view of contemporary changes in aquatic environments, determining the distribution of both native and emerging invasive crayfish species is increasingly important.

Simultaneous detection of invasive signal crayfish, endangered white-clawed crayfish and the crayfish plague pathogen using environmental DNA [PDF]
Biological Conservation, 2018 ABSTRACTAquatic Invasive Species (AIS) are important vectors for the introduction of novel pathogens which can, in turn, become drivers of rapid ecological and evolutionary change, compromising the persistence of native species. Conservation strategies rely on accurate information regarding presence and distribution of AIS and their associated ...

The Prevalence of Crayfish Plague (Aphanomyces Astaci) in Two Signal Crayfish (Pacifastacus Leniusculus) Populations in Finland [PDF]
Journal of Crustacean Biology, 2000 Abstract The occurrence of dark brown melanized spots indicative of the presence of crayfish plague fungus (Aphanomyces astaci Schikora) was investigated in three Finnish lakes inhabited by the introduced American signal crayfish (Pacifastacus leniusculus Dana) in 1979, 1983, 1985–1988, 1990, 1993, and 1994. The crayfish were caught with crayfish traps

Terrestrial dispersal of invasive signal crayfish during vulnerable life stages [PDF]
Behavioural Processes, 2018 1. Aquatic invertebrates commonly disperse between waterbodies by flight, though some decapods can emigrate from the water and walk overland. 2. The signal crayfish (Pacifastacus leniusculus, Dana) is a highly invasive species that can survive for days to weeks out of water, though it is unclear to what extent vulnerable life stages, such as ovigerous ...
