Narrow-clawed crayfish Astacus leptodactylus (Eschscholtz, 1823) The distribution of narrow-clawed crayfish is mainly linked with the south-eastern region of the country and more rarely in the rest of Latvia (Bērziņš 1936, Mazītis 1955, 1967, 1971). Earlier evaluations of the distribution of this species have been quite inconsistent.

Drug and chemical toxicology (New York, N.Y. 1978), 2020
Azoxystrobin is a broad-spectrum fungicide used worldwide. Since azoxystrobin spreads to large areas, its toxic effects on non-target organisms have aroused interest.

Ontogeny of Osmoregulation in the CrayfishAstacus leptodactylus
Physiological and Biochemical Zoology, 2000Osmoregulation was studied during the postembryonic development of Astacus leptodactylus Eschscholtz 1823 in juvenile stages 1-8 and in adults. Juveniles hatch and later stages develop in freshwater or in moderately saline waters. The time of acclimation from freshwater to a saline medium increased from early juveniles to adults.

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1977
Abstract 1. 1. Composition of egg proteins of Astacus astacus and A. leptodactylus is compared by different methods. 2. 2. Disc electrophoresis reveals seven fractions in each case, four of them being identical in both species. 3. 3. By immunodiffusion (double diffusion test) three precipitin lines can be obtained, with one of them fusing.
