Pathogen diversity of the non-native narrow-clawed crayfish (Pontastacus leptodactylus) in a UK water body.

Journal of Invertebrate Pathology
Biological invasions are intrinsically linked to introducing associated symbiotic organisms, some of which can be parasitic or pathogenic. The pathogenic risk of an 'invasive parasite' (aka.

Rapid assessment of population dynamics and monitoring methods for invasive narrow clawed crayfish Pontastacus leptodactylus in a freshwater reservoir [PDF]

Knowledge and Management of Aquatic Ecosystems
Narrow-clawed crayfish (Pontastacus leptodactylus) are a data deficient invasive non-native species in the UK. Boshaw Whams (West Yorkshire, UK) contains the only known population of narrow-clawed crayfish in Yorkshire.

Effect of chloride content in water on heart rate in narrow-clawed crayfish (Astacus leptodactylus) [PDF]

Knowledge and Management of Aquatic Ecosystems, 2009
A non-invasive method of recording cardiac activity was used to examine the impact of chloride level in water on narrow-clawed crayfish. This method permits one to record heart rate without any harm to the animal, and also locates changes in the shape ...
