Cheliped loss and abnormalities of the narrow-clawed crayfish, Pontastacus leptodactylus (Eschscholtz, 1823) (Crustacea: Decapoda: Astacidae) [PDF]
Heterochely is an important phenomenon in decapod crustaceans. Nevertheless, it was rarely examined in freshwater crayfish. Therefore, the aim of this study was to investigate cheliped loss and abnormalities of the narrow-clawed crayfish, Pontastacus ...

Morphology of the narrow-clawed crayfish (Astacus leptodactylus Eschscholtz, 1823) in the north-west Croatia [PDF]
Astacus leptodactylus jedna je od četiri nativne vrste porodice Astacidae u Hrvatskoj, ujedno je i ključna vrsta u slatkovodnim ekosustavima. Unatoč važnosti vrste A. leptodactylus, općenito nedostaju podaci o toj vrsti na europskom nivou.

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.

The sublethal effects of (2,4-Dichlorophenoxy) acetic acid (2,4-D) on narrow-clawed crayfish (Astacus leptodactylus Eschscholtz, 1823) [PDF]
Abstract2,4-D is a widely used phenoxy herbicide, potentially toxic to humans and biota. The objective of the present study was to reveal short term sublethal effects of 2,4-D on narrow-clawed freshwater crayfish (Astacus leptodactylus Eschscholtz, 1823), based on histology, total haemocyte counts, selected haemolymph parameters, and oxidative stress ...

Better Alone Than in Bad Company: Trophic Ecology of Co-Occurring Invasive and Native Crayfish. [PDF]
This study investigated and compared trophic interactions between invasive signal crayfish and native white‐clawed crayfish at sites of co‐occurrence and in allopatry. The presence of crayfish plague, body condition, and trophic niche traits were explored as possible factors that make invasive signal crayfish a strong competitor, enhancing its ...

Physiology of Ovarian Development in Crustaceans: Interactions Among Hormones, Nutrients, and Environmental Factors From Integrated Perspectives. [PDF]
Reproductive maturation remains a central bottleneck in crustacean aquaculture, as ovarian development dictates broodstock quality, fecundity, and larval viability. This review synthesizes current knowledge on the physiological regulation of ovarian maturation in decapod crustaceans, emphasizing the interplay of hormones, nutrients, and environmental ...
