The freshwater crayfish Astacus leptodactylus (Eschscholtz, 1823) is an important aquacultured decapod species as well as an invasive species in some European countries. In the current investigation we characterized the different classes of circulating blood cells in A. leptodactylus by means of light and electron microscopy analysis and we explored their reaction to different latex beads.
Organism Astacus leptodactylus (Turkish narrow-clawed crayfish) (Pontastacus leptodactylus).
The effects of seasonal, sex and size on digestive enzyme activities of Astacus leptodactylus in natural habitat were investigated in the present study. The freshwater crayfish were sampled 584 individual as seasonally from Egirdir Lake.
Astacus leptodactylusis a widespread species distributed throughout Europe, the eastern Russia, and the Middle East (Souty-Grosset et al.2006). Freshwater crayfish has had an economic importance in Turkish markets. Recently, there has been an increase, gradually. In 1990s, the annual crayfish production was between 300 and 500 tonnes.

Narrow-clawed crayfish (Astacus leptodactylus Eschscholtz, 1823 species-complex) is one of five European freshwater crayfish species. Even though widely distributed, it hasn’t been frequently studied and its taxonomy and systematics are unresolved. The results of a recent comparative morphometric character study revealed that morphometry of Asian and European populations differ significantly.
Subject browse uses CABICODES which are CABI’s own classification codes for broad subjects that would be difficult to describe with keywords alone. Each database record is assigned with at least one CABICODE which describes the relevant area of science. Click on a subject area to search for all records coded with that CABICODE.
The Astacus leptodactylus specimens were collected from four sites of Aras reservoir, North-West of Iran and examined for the epibionts during 2009. Protozoan epibionts from ciliophora (one genus and seven species) and tracheophyta were isolated from the cuticular surface of different body parts of narrow-claw crayfish, A.leptodactylus.
