Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts

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.

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.
