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.

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.

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 ...

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 ...

Exploring the Coexposure Effects of Pyrogallol and Microplastic on the Red Swamp Crayfish Procambarus clarkii

Aquaculture Research, Volume 2025, Issue 1, 2025.
Investigating the impact of two or more toxic chemicals on aquatic organisms is one of the main objectives of toxicological research. Microplastics (MPs) are identified as a carrier or vector for other pollutants. Therefore, the current study investigated the effects of both pyrogallol (PG) and MPs, individually and in combination, on freshwater ...
