First record of Astathelohania contejeani (Henneguy, 1892) in the narrow-clawed crayfish Pontastacus leptodactylus (Eschscholtz, 1823) from Belarus

Oceanological and Hydrobiological Studies
Porcelain disease, caused by the parasite Astathelohania contejeani, is a fatal disease for freshwater crayfish. Previously published data provide information on the occurrence of A. contejeani in various crayfish species. However, its prevalence in host

Elevated water temperature impairs gamete production in male narrow-clawed crayfish Pontastacus leptodactylus (Eschscholtz, 1823)

Knowledge and Management of Aquatic Ecosystems, 2018
Water temperature is one of the major environmental factors affecting the reproductive output of freshwater crayfish. The reproduction of freshwater crayfish only occurs in a limited water temperature range and minor changes in water temperature could ...

Molecular-genetic testing of freshwater species and breeds of animals (fish, narrow-clawed crayfish, mollusks)

Faktori eksperimental'noi evolucii organizmiv, 2018
Aim. Description of the results of molecular genetic studies of a number of fish, narrow-clawed crayfish, and mollusk species. Methods. For the analysis, RAPD, SSR, and DNA-barcoding methods were used. Results. Unique RAPD amplicones were identified to differentiate Lahvinsky, Tremlyansky and Isobelinsky carp breeds.

Comparative biology of the signal crayfish, Pacifastacus leniusculus (Dana), and the narrow-clawed crayfish, Astacus leptodactylus Eschscholtz [PDF]

, 1996
Some aspects of the biology of Pacifastacus leniusculus and Astacus leptodactylus have been compared. The literature survey shows that considerably more studies have been carried out on P. leniusculus than A. leptodactylus. Although no major differences have been found in the morphology of appendages and mouthparts of the species, structural ...
