Cheliped loss and abnormalities of the narrow-clawed crayfish, Pontastacus leptodactylus (Eschscholtz, 1823) (Crustacea: Decapoda: Astacidae) [PDF]

Nauplius
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 ...

Tail Fan Necrosis syndrome in decapod crustaceans: A review

Journal of Fish Diseases, Volume 47, Issue 5, May 2024.
Abstract Lobsters and crayfish in Australasia can develop a condition known as Tail Fan Necrosis (TFN syndrome). Many attempts have been made to find a primary pathogen or link the syndrome to commercial activities, but a solution remains elusive. TFN syndrome is a ‘wicked problem’, a problem difficult or impossible to solve because of incomplete and ...

The first Marmorkrebs (Decapoda: Astacida: Cambaridae) in Scandinavia

BioInvasions Records, 2013
Invasive crayfish have attracted much attention by scientists and policy makers in Europe, partly due to their ability to transmit diseases to native crayfish species. In December 2012, 13 specimens of a new crayfish species were found in the River Marstaan in central Sweden.

Meta‐analytic assessment of physiological markers for decapod crustacean welfare

Fish and Fisheries, Volume 25, Issue 1, Page 134-150, January 2024.
Abstract Decapod crustacean welfare is not only an ethical consideration for legislative purposes. Under culture and fishery settings, poor environmental conditions and operator practices can cause stress, which compromises the immune system and increases the risk of disease.

Systematics of the European Endangered Crayfish Species Austropotamobius Pallipes (Decapoda: Astacidae) [PDF]

Journal of Crustacean Biology, 2000
Abstract Mitochondrial DNA sequence variation in the 16S rRNA gene was used to estimate the phylogenetic relationships of Austropotamobius pallipes. The program ModelTest was used to test alternative models of evolution for our data using likelihood ratio tests.

Additional supply of decapsulated Artemia cysts for various periods in intensive rearing of juvenile crayfish (Pacifastacus leniusculus, Astacidae)

Knowledge and Management of Aquatic Ecosystems, 2011
The additional supply of live feeds such as Artemia remains indispensable in juvenile astacid rearing from the start of independent life. Considering that cost and work could be reduced by restricting this supply, a 100-day experiment was carried out ...

Antifungal treatments in artificial incubation of crayfish eggs (Pacifastacus leniusculus, Astacidae): Searching for alternatives to formaldehyde [PDF]

Knowledge and Management of Aquatic Ecosystems, 2009
Considering the concerns about the safety of the use of formaldehyde as antifungal agent, the effects of three alternative chemicals (potassium sorbate, copper hydroxide and magnesium chloride) were tested in the artificial incubation of signal crayfish (

Eradication attempt for an early detected invasive crayfish: the case of Pacifastacus leniusculus (Decapoda, Astacidae) in the Clitunno River (central Italy) [PDF]

NeoBiota
The signal crayfish Pacifastacus leniusculus (Dana, 1852) is one of the most ecologically impactful decapod crustaceans introduced in Europe. As a species of Union concern, early detection and rapid eradication measures are required to prevent its ...
