Fecundity of the narrow-clawed crayfish Pontastacus leptodactylus in the water bodies of Belarus

open access: yesProceedings of the National Academy of Sciences of Belarus, Biological Series, 2023
Pre-larvae hatching fecundity and ovarian fecundity of narrow-clawed crayfish populations were estimated in the lakes and reservoirs of Belarus. Statistically significant differences in the fecundity of females from various water bodies were noted only for Lake Kichino.

Interactions between metals accumulated in the narrow-clawed crayfishAstacus leptodactylus(Eschscholtz, 1823) in Dikilitaş Lake, Turkey [PDF]

open access: yesChemistry and Ecology, 2015
The accumulations of Al, Cd, Cr, Cu, Fe, Ni, Pb and Zn in the exoskeleton, gills, hepatopancreas and abdominal muscles of crayfish Astacus leptodactylus (Eschscholtz, 1823) were determined. The strongest correlation observed was between Cr and Ni in the gills (r = 0.904); moderate to strong correlations between Al, Cr, Fe, Ni and Cu were also observed ...

Observations of crayfish plague infections in commercially important narrow-clawed crayfish populations in Turkey

open access: yesKnowledge and Management of Aquatic Ecosystems, 2018
We studied the presence of possible Aphanomyces astaci infections in eight Turkish narrow-clawed crayfish (Astacus leptodactylus) populations by analyzing the prevalence and genotypes of the disease agent A. astaci. The qPCR analyses revealed A.

Dead Matter, Living Machines: Repurposing Crustaceans' Abdomen Exoskeleton for Bio‐Hybrid Robots

open access: yesAdvanced Science, Volume 13, Issue 15, 13 March 2026.
Crustacean exoskeletons, repurposed from food waste, are engineered into sustainable bending actuators combining biotic structure with synthetic control. The augmented exoskeletons achieve rapid and robust motion with lightweight body and can be used as part of robotic manipulators, grippers and swimmers.

Farming of the Juvenile Narrow-clawed Crayfish (Astacus leptodactylus) in Cages and Ponds in Polyculture With Fish in the Heated Waste Water of the Thermal Power Plantf [PDF]

open access: yes, 2010
Experimental research has been carried out on fanning of the narrow-clawed crayfish larvae in ponds and cages in the TPP waste water. It was shown that farming in such conditions during the first vegetation period was more effective, than in water bodies
