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.

Shelter Occupancy by Mixed-Species Pairs of Native Signal Crayfish and Non-Native Red Swamp Crayfish Held in Enclosures [PDF]
Journal of Freshwater Ecology, 2009 ABSTRACT Sheltering ability does not appear to confer an advantage to non-native red swamp crayfish (Procambarus clarkil) in a small, western Washington lake where the invader outnumbers the native signal crayfish (Pacifastacus leniusculus.) When paired with similar-sized non-native P. clarkii, P.

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.

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 ...
