A PROPOSAL FOR ACCEPTING PONTASTACUS AS A GENUS OF EUROPEAN CRAYFISH WITHIN THE FAMILY ASTACIDAE BASED ON A REVISION OF THE WEST AND EAST EUROPEAN TAXONOMIC LITERATURE

Knowledge and Management of Aquatic Ecosystems, 2006
The taxonomic classification of European crayfish is neither fully examined nor generally accepted as a unifying scheme. At present, one of the most obvious differences exists between astacologists from Western and Eastern Europe.

Prevalence, molecular identification and genotyping of the crayfish plague pathogen, Aphanomyces astaci in major narrow-clawed crayfish (Pontastacus leptodactylus Eschscholtz, 1823) populations from Türkiye

Journal of Veterinary Research
Crayfish plague is considered the most important crayfish disease globally. It is caused by the fungus-like agent, Aphanomyces astaci. This study aimed to identify and determine the prevalence of A. astaci using PCR in narrow-clawed crayfish (Pontastacus

Dietary Pectin Supplementation as a Potential Strategy to Mitigate the Toxic Effects of Microplastics and Cadmium in Freshwater Crayfish (Astacus leptodactylus)

Aquaculture Research, Volume 2026, Issue 1, 2026.
This study investigated the effects of cadmium (Cd), microplastics (MPs), and pectin (Pec) supplementation on biochemical, oxidative, and immunological parameters in crayfish (Astacus leptodactylus). Four hundred fifty crayfish were acclimatized under controlled laboratory conditions and distributed into 15 experimental groups using a definitive ...

Trophic plasticity and invasive success: dynamic feeding strategies of the signal crayfish in Croatian rivers

Journal of Freshwater Ecology
The invasive signal crayfish (Pacifastacus leniusculus), a species of high concern in European freshwaters, represents a substantial threat to native crayfish species and freshwater ecosystems.

Neural Repertoire Behind the World's Most Complex Retina: Neuroanatomy of the Stomatopod Lamina

Journal of Comparative Neurology, Volume 533, Issue 6, June 2025.
The lamina behind the complex retina of mantis shrimp is highly conserved between eye regions and species and is similar to crustaceans and distinct from insects. Midband cartridges connect along columns, providing a neural basis for the unique scanning behavior of stomatopods.

Better Alone Than in Bad Company: Trophic Ecology of Co‐Occurring Invasive and Native Crayfish

Ecology and Evolution, Volume 15, Issue 5, May 2025.
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 ...

A Review on the Role of 2–8 Carbon Chain Carboxylates in Enhancing Aquaculture Performance

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
Two to eight carbon chain carboxylates enhance aquaculture sustainability and productivity by improving growth performance, immune responses, environmental management, reducing antibiotic reliance, and promoting a circular economy. ABSTRACT Aquaculture is a key sector for global food security, but its sustainability and productivity remain constantly ...

Physiology of Ovarian Development in Crustaceans: Interactions Among Hormones, Nutrients, and Environmental Factors From Integrated Perspectives

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
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 ...

Effects of Rhodotorula mucilaginosa on Growth, Antioxidant, and Immune Function, and Toll/Imd and JAK‐STAT Signaling Pathways in Red Claw Crayfish (Cherax quadricanatus)

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
In aquaculture, the use of probiotics to improve growth, immunity, and stress resistance in crustaceans has gained increasing attention. This study examined the effects of incorporating different levels of Rhodotorula mucilaginosa (0.0, 0.1, 1.0, and 10.0 g/kg) into the diet on growth performance, antioxidant capacity (AOC), immune function, Toll/Imd ...
