As in other benthic decapods, crayfish have chelae that are important for intra‐specific agonistic encounters. In Austropotamobius pallipes, scars and mutilations are present mostly on the chelae, these being the main targets of agonistic contacts. Because males participate in more aggressive interactions than females do and compete with other males ...

Currently, the distribution of the European native white-clawed crayfish (Austropotamobius pallipes) is restricted, fragmented and mainly located in headwater streams. Many European countries have active programmes for its conservation and some also have reintroduction programmes.

The white-clawed crayfish is generally considered as an endangered species and it is necessary to estimate the functioning quality in residual population patches, particularly reproduction. For six consecutive years, a population was studied in a forest brook in Normandy (France). The size, state of maturity, density and egg number in mature females as

Embryonated eggs of theEuropean native white-clawed crayfish Austropotamobius pallipes Lereboullet weresubjected to three periods of storage usingpolystyrene boxes and, afterwards, artificiallyincubated. At the end of the longest storage(42 days) survival rate was 98.3%, with 65%developed to stage 2 juvenile.

Journal of Invertebrate PathologyAphanomyces astaci is the oomycete responsible for crayfish plague, a disease with devastating effects on susceptible crayfish populations across Eurasia. Recently, low virulence strains of this oomycete, mostly belonging to genetic group A, have been reported to coexist with European crayfish species.

Here we report a high level of mtDNA variationfrom RFLP analysis within A. p. pallipes from 21 French and 4British populations. Seventeen haplotypes were recorded among 269individuals. Nucleotide sequence divergence (p) among mtDNAhaplotypes ranged from 0.0019 to 0.0425.

Phylogenetic position of white-clawed crayfish from the east Adriatic coast
2010The white-clawed crayfish (Austropotamobius pallipes (Lereboullet)) is a native European freshwater crayfish inhabiting Croatian freshwater habitats. It is naturally distributed in the Adriatic Sea drainage, while in Europe it is found in its southern and western parts, including British Isles.
